  • Comparative study on the composition and functional proprieties of chitin/chitosan extracted by new combined bioprocess.

    Bessadok, Boutheina; Sadok, Saloua (2023)
    INSTM Bulletin: Marine and Freshwater Sciences
    Bio-extraction of chitin is a greener and eco-friendly process than the conventional chemical method. Taking shrimp waste of Pandalus borealis recovered from plant as a model, two methods were applied for chitin extraction; a chemical and a yeast-based processes (Ch-C and Ch-B respectively). The recovered chitins and chitosan were tested for their biochemical and functional properties. Compared to commercial chitin, both lots, have similar chitin recovery (~26%) and physiochemical properties with ash<1%, protein <10%, with degrees of acetylation (DA) varying 70-80%. However, chitosan obtained from Ch-B lot showed significantly lower molecular weight (MW) and DA (MW: 6.34 KDa, DA: 23.4%) than that found in Ch-C chitosan (MW: 11.36 KDa, DA: 33.4%). The new method proved to be efficient for the production of chitosan of good quality which allowed the elaboration of the membrane.
  • Effects of chitosan-microparticles-coating on the quality of vacuum-packed sea bass (Dicentrarchus labrax) fillets during refrigerated storage.

    Besbes, Nadia; Sadok, Saloua (2023)
    INSTM Bulletin: Marine and Freshwater Sciences
    In this work, a combination of vaccum pachaging and bio-coating by chitosan were used to coat sea bass (Dicentrarchus labrax) fillets in order to delay growth of total mesophilic aerobic bacteria, psychrophilic bacteria during refrigerated storage (22 days). The preservative effect of refrigerated and vacuum-packed seabass (Dicentrarchus labrax) fillets treated at two different percentage doses (0.2% and 0.5% w/w) of co-products of shellfish was evaluated on the basis of microbiological, proximate composition, pH, total volatile basic nitrogen (TVB-N), trimethylamine (TMA), thiobarbyturic acid (TBArs), and fatty acids (FA). Two ways ANOVA and multiple comparisons were applied, factors being storage time and treatment. During refrigerated storage, the treatment with chitosan from separate co-products exhibited more antimicrobial activity and the lowest value of the TVB-N, TMA and TBArs compared to control lots. The bio-coating by 0.5% dose of chitosan preserved quality and the prolonged shelf-life for 10 days longer. Overall, this treatment may open new promising opportunities for the biopreservation of fish products by enhancing the period of storage of refrigerated and vacuum-packed seabass fillets.
  • Overview of Bottlenose dolphin depredation in Teboulba region (East of Tunisia).

    Ben Massaoud, Rimel; Gharbi, Maissa; Cherif, Mourad; Koched, Wael; Ben Nakhla, Lobna (2023)
    INSTM Bulletin: Marine and Freshwater Sciences
    This work was carried out in response to the numerous fishermen claims following to the interaction between dolphins and fishing gears along the coast of Teboulba. The aims of this work were: to establish an inventory of dolphins present in the study area and interacting with fisheries, to define the most affected fisheries by the depredation and to attempt to assess it economic consequences. For this purpose, field surveys as well as weekly monitoring of a sample of the fleet and sea trips were carried out in order to respond to the previously mentioned objectives. The findings of this study led to the conclusion that there are two dolphin’s species: the Bottlenose dolphin and the Striped dolphin. These two species have a different demographic and ecological distribution. They also interact in two different ways with the fishing boats and their nets. According to the surveys, the most depredated fisheries is the small scall fisheries. Set gillnet and trammel nets were the types of the fishing gear most vulnerable to dolphin depredation. The depredation rate and economical loss due to depredation vary slightly between gillnets and trammel nets. The depredation induces many holes with different size requiring mending operations that can be onerous. Likewise for landing, the resulting bites on the catch leave it unsaleable. It is necessary to continue this study in order to identify the factors that can cause the depredation and propose mitigation measures to avoid any ecological and economic blunder.
  • Age et croissance de l'allache ou sardinelle ronde (Sardinella aurita Valenciennes, 1847) dans le Cap Bon (Tunisie).

    Gaamour, Adel; Missaoui, Hechmi; El Abed, Amor; Deniel, Christian (2001)
    Bulletin de l'Institut National des Sciences et Technologies de la Mer de Salammbô
    A new esseous part, the opercula bone, is used to estimate age of 2009 round sardine (Sardinella aurita Valenciennes, 1847) captured in the Cap Bon area. The period of sampling with a monthly rhythm, is spread out June 1994 at December 1995 and from June to September 1996. Th relation between the length of fish (LF) and the ray of opercula (RT) is LF= 22,25 RT 0,994 . The validation of age estimate method is carried out directly by the monthly follow-up of overage marginal lengthening and the percentage of individuals with marginal hyaline zone. This study showed that the round sardine has a double cycle of growth of the age-length shows that the females dominate in the majority of age groups the parameter of growth in length according to the model of Von Bertalanffy are estimated by direct enumeration of the hyaline zone and retrocalcul. The curves of growth obtained by employ retrocalculed data describe better the growth of the round sardine in Cap Bon area.
  • Résultats Généraux des Pêches Maritimes 2019.

    Ministère des Pêches et de l'Economie Maritime, Dakar (Sénégal). Direction des Pêches Maritimes (DPM) (Direction des Pêches Maritimes, 2022)
    La Direction des Pêches maritimes assure la mise en œuvre de la politique de l’Etat en matière de pêches maritimes artisanale et industrielle. A ce titre, elle a pour mission, entre autres, la collecte, le traitement et la publication des statistiques des pêches maritimes. Les données de la pêche artisanale maritime proviennent des services déconcentrés des pêches. Elles sont collectées sur des fiches confectionnées par les services eux-mêmes et faisant appel aux techniques d’échantillonnage aléatoire simple. Par ailleurs d’autres méthodes se fondent sur l’enregistrement et l’exploitation des données dans des cahiers de sondage, des certificats de contrôle d’origine et de salubrité (COS) et des certificats à la première vente (CPV). En ce qui concerne la pêche industrielle, les données de base proviennent essentiellement des journaux de pêche renseignés depuis 2017 par les capitaines des navires et sont complétées par les notes de pêches (bon de pesée) et les manifestes de déclaration fournis par la Douane aux armements. Les données des crevettiers profonds sénégalais et des navires de l’Union européenne opérant dans le cadre de l’accord de pêche avec le Sénégal sont collectées au moyen du système ERS mise en place. L’ensemble des données collectées sont centralisées à la DPM où elles sont saisies, traitées, analysées et publiées sous forme d’un rapport annuel intitulé « Résultats généraux des pêches maritimes ». Ce rapport est produit pour répondre aux différentes sollicitations des utilisateurs. Les débarquements de la pêche maritime de l’année 2019 s’élèvent à 533 479 tonnes pour une valeur commerciale estimée à 272,602 milliards de FCFA contre 524 851 tonnes pour une valeur commerciale estimée à 272,466 milliards en 2018. En glissement annuel, on note une légère augmentation des débarquements en volume de 1,64% et en valeur de 0,05 %. Les quantités de produits de la transformation artisanale s’élèvent à 56 860,91 tonnes pour une valeur de 53,150 milliards de FCFA contre 51 236,84 tonnes l’année dernière pour une valeur de 42,115milliards. Comparée à 2018, nous notons une hausse de 11% en volume et 12% en valeur. Le mareyage des produits frais s’élève à 232 875 tonnes contre 193 990 tonnes en 2018, soit une hausse de 20%, et celui des produits transformés tourne autour de 16 698 tonnes sur le marché intérieur. La distribution locale totale des produits frais au sein des régions maritimes s’élève à 50 810 tonnes. Quant aux exportations, elles sont passées de 293 792,00 tonnes en 2018 à 311 882,51 tonnes en 2019, soit une hausse de 18 090,51 tonnes en valeur absolue et 6% en valeur relative. Quant à la valeur commerciale, elle est passée de 299,184 milliards en 2018 à 308,208 milliards en 2019, soit une augmentation de 3%.
  • Effects of dilution ratio on the potency and viability of the spermatozoa of African Catfish (Clarias gariepinus Burchell, 1822) using normal saline solution.

    Egwenomhe, Marinus; Oghenevwairhe, Emefe; Momoh, Blessing (2020)
    Journal of Agriculture and Environment
    Normal saline solution is one of the most common diluents in artificial breeding and to dilute the milt of C. gariepinus, however the most desirable quantity or volume to be used is still a problem leading to several failures in artificial propagation of fish. The study determined the effects of dilution ratio on the potency of the spermatozoa, fertilization and hatchability rate of the eggs and survival rate of the hatchlings. The dilution ratio used included milt to saline solution ratio of: 1:10 (T2), 1:50 (T3), 1:100 (T4), and zero saline inclusion (T1), as the control. The experiment was laid out in a complete randomized design (CRD) with 3 replications each for the treatments. The result showed that there was significant difference (P<0.05) in percentage motility of the milt, egg fertilization and hatchability rate, and survival rate of the larvae across the treatments. The highest percentage motility (87.67%), fertilization (97.55%), hatchability (87.78%) and survival rate (I83.53%) occurred at T2 (1:10), while the least percentage motility (49%), fertilization (75.89%), hatchability (40.73%) and survival rate (45.43%) occurred at T1 (zero saline inclusion). It can be concluded that normal saline improves artificial propagation of C. gariepinus and with further increase of normal saline solution there is a negative effect on the potency of the milt, fertilization and hatchability of the eggs and survival rate of the hatchlings. A dilution ratio of 1:10 is therefore recommended to fertilize eggs of C. gariepinus for improving artificial propagation of fish
  • Heavy metal concentrations in the West African clam, Egeria radiata (Lammark, 1804) from McIver market, Warri, Nigeria.

    Nwabueze, Aghata; Oghenevwairhe, Emefe (2012)
    International Journal of Science and Nature
    Samples of Egeria radiata were purchased from local dealers in McIver mar et, Warri, Nigeria, to investigate the presence and concentrations of some heavy metals in order to ascertain the suitability of the clam for human consumption. Analyses using Atomic Absorption Spectrophotometer (AAS) show that E. radiata accumulated some heavy metals with the following sequence of concentration: Iron> Nic el> Lead> Copper> Arsenic> Manganese> Chromium> Cadmium> Mercury. The variability of heavy metals concentration observed in E. radiata during the period of study was affected by rainfall amount. A negative relationship between changes in rainfall and body weight of clams show that the higher the rainfall the lower the mean dry weight. Individual heavy metal differed significantly (P< 0.05) in concentration. However, heavy metal concentrations did not vary significantly (P> 0.05) by months. Out of the nine heavy metals found in E. radiata tissues, lead and cadmium were higher than the WHO/FAO set limit. E. radiata sold in McIver mar et during this period of study were contaminated with lead and cadmium and therefore not fit for consumption.
  • Gynogenesis: An effective way of controlling fish population and increasing profit in aquaculture

    Emefe, Oghenevwairhe; Sorhue, Ufuoma Godstime (Genetics Society of Nigeria, 2014)
    Gynogenesis is a gene manipulation technology to produce all female fish. Brood stock of Clarias gariepinus were obtained from a fish farm in Mosogar, Delta State, Nigeria. The milt was irradiated with Ultra Violet (UV) light to inactivate the male chromosomes. The fertilized eggs were then cold shocked. One way analysis of variance was use to analyze the data on the haploids, triploids and diploids. Hatchability of fertilized eggs indicated lower hatchability and survival rates in the diploids and the triploids. Analysis of variance showed significant difference in the growth of the diploid and triploid. There were also higher growth rates in the triploid than the diploids.

  • Fisheries Statistical Report Year 2021

    Seychelles Fishing Authority (Seychelles Fishing Authority, 2022)
    This Seychelles Fisheries Statistical Report present annual updates of fisheries statistics for the industrial, semi-industrial, artisanal, sea cucumber and lobster fishery by vessel type, species, and geographical locations for the year 2021. Profiles of each fishery, summary of data collection and processing procedures are also provided. For the purse seine fishery, 46 purse seiners holding licences to fish inside the Seychelles EEZ reported a total catch of 412,922 MT in the in the Western Indian Ocean (WIO), for the year 2021. This represents a 17% increase over the estimated catch of 353,675 MT reported in the year 2020. The Spanish fleet accounted for 38% of the total catch in the WIO for year 2021, whilst the Seychelles and French fleet accounted for 30% and 19% respectively. A total catch of 43,001 MT was reported inside the Seychelles EEZ during the year 2021 representing a 55% decrease from the 95,668 MT reported for the year 2020. This corresponds to a decrease of 49% in fishing effort in 2021 when compared to the previous year. It is worth noting that the catches and effort reported in 2021, was the lowest recorded inside Seychelles EEZ since 2013 and the decrease may be due to the change in fishing ground, with higher availability of tuna outside Seychelles EEZ. In terms of species composition, Skipjack tuna dominated the total purse seine catches, accounting for 61% of the total catch followed by yellowfin and bigeye tuna representing 29%, and 9% of the total catch respectively. Skipjack, yellowfin, and bigeye tuna catches increased by 13%, 8% and 122% respectively in 2021 when compared to the year 2020. It is worth noting that in 2021, SFA encountered technical issues with its purse seine data processing software which did not allow for the species composition corrections. Hence the species composition provided here may change following species composition correction. The Seychelles flagged purse seiners reported a total catch of 122,855 MT in the WIO in 2021, achieved from a fishing effort of 3,027 fishing days thus giving a mean catch rate of 40.60 MT/fishing day. This represents an increase of 9% in catches and a slight decrease of 6% in fishing effort. In 2020 the Seychelles purse seine fleet reported a total catch of 112,231 MT obtained from a fishing effort of 3,221 fishing days with a mean catch rate of 34.84 MT/fishing day. Species composition of the Seychelles purse seine fleet in the year 2021 comprised of 24% yellowfin tuna (29,407MT), 66% of skipjack tuna (81,390MT) and 9% of bigeye tuna (11,230MT). This represents a decrease of 4% in yellowfin tuna catches and an increased of 8% and 91% in skipjack and bigeye tuna respectively. Like previous years, Port Victoria remained the principal port for tuna transhipment and landing by purse seiners in the WIO during the year 2021. A total of 387,992 MT of tuna was unloaded through port Victoria compared to 335,074 MT in 2020. This represents 93% of the total landing and transhipment for that year and a 16% increase from the previous year. For the industrial longline fishery, 188 vessels licensed to fish in the Seychelles EEZ during year 2021 reported an estimated catch of 25,340 MT, obtained from a fishing effort of approximately 66.6 million hooks. This resulted in a mean catch rate of 0.38 MT/1000 hooks, a much lower catch rate than 0.55 MT/1000 hooks estimated for the previous year. The total catch reported by 162 vessels in the year 2020 was 31,496 MT, obtained from a fishing effort of approximately 57.4 million hooks. Only 58% of the total reported catch or 14,575 MT of fish were reported to have been caught inside of the Seychelles EEZ during the year 2021 despite an increase of 49% in fishing effort inside the Seychelles EEZ. In terms of species composition, bigeye tuna catches accounted for 41% of the total catch whilst Yellowfin tuna, swordfish and the `others’ category represented 27%, 7% and 16% of the total catch comparable to the year 2020. During the year 2021, the 64 Seychelles flagged industrial longliners reported an estimated catch of 14,526 MT representing a decrease of 35% in catches despite just a slight decrease of 2% in fishing effort. During the previous year, the 62 Seychelles flagged vessels reported a total catch of 22,469 MT. Species composition of the Seychelles industrial longline fleet in the year 2021 comprised of 21% yellowfin tuna (3064.2MT), 40% of bigeye tuna (5825.8MT) and 24% of “other species” (3549.7MT). This represents a decrease of 61% and 21% in yellowfin and bigeye tuna catches respectively and an increase of 36% in catches of “Other species”. In the semi-industrial fishery, a total of 375 fishing trips targeting tuna and swordfish were conducted by 41 semi-industrial longliners in the year 2021. This represents an increase of 23% in number of trips targeting swordfish and tuna over the 306 fishing trips conducted in 2020 by 35 vessels. The total catches by the Semi industrial vessels increased by 18% to reached 1,759 MT compared to 1,485 Mt the previous year corresponding to an increase of 36% in fishing effort. In terms of species composition, yellowfin tuna accounted for 89% of the total catch followed by swordfish and bigeye tuna accounting for 6% and 3% of the total catch, respectively. During the previous year, the semi-industrial catches was dominated by yellowfin (86%) followed by swordfish (9%) and bigeye tuna (4%). The mean number of boats operating per month in the artisanal fishery, during the first semester of year 2021 has increased to 327 boats active per month when compared to a mean of 303 boats active per month during the first semester of the year 2020 (the covid19 pandemic period). The highest increased was observed in the mean number of schooner active, 56 in 2021 compared to 43 in the year 2020. The artisanal fleet was still dominated by outboard vessels accounting for 62% of the fleet with whalers and schooners accounting for 19% and 17% respectively. During the first semester of the year 2021, the total artisanal catches increased by 28% to reach 2346 MT compared to a total catch of 1833 MT estimated for the same period the previous year. Typical of previous years, the handline fishery dominated artisanal fisheries catches, accounting for 70% of total landings during the first six months of 2021.The most important species groups landed for the first semester of the year 2021 were carangues (24%), bourgeois (14%) and job (11%). During the first six months of the year 2021, the total fishing effort for handline, trap and net fishery increase by 43%, 58% and 41% respectively. The Catch rate for the handline and net fishery decreased during the first semester of the year 2021 when compared to same period the previous year. The catch rate for trap fishery has remained unchanged. For the sea cucumber fishery, the landings in numbers for the 2020/2021 fishing season were 243,169 Flower teatfish, 53,241 White teatfish, and 38,494 Prickly redfish. This represents a decrease of 10% and 22% for Flower teatfish and White teatfish respectively and an increase of 4% for Prickly redfish compare to the 2019/2020 season. Fishing efforts have increased over the years, with 155 trips completed in 2020-2021, two trips less than the 2019/2020 season. The lobster fishery catch fluctuates from season to seasons. The highest catch of 6.1 MT was recorded in the 2020/2021 season, whereas the lowest catch of 0.61 MT was recorded in the 2013/2014 season. A notable peak in catch was recorded in 2019/2020 following a two-year closure. In terms of catch composition for the targeted species, historically P. penicillatus dominated the catch for all seasons with an average of 2.9 MT per season, followed by P. longipes with an average of 0.9 MT per seasons. A total of 242 fishing trips were recorded during the 2020/2021 season compared to only 196 trips in 2019/2020 representing an increase of 23%.

  • Seychelles’ 1st Report to the Fisheries Transparency Initiative (FiTI) Calendar year: 2019

    FiTI National Multi-stakeholder Group of Seychelles (MSG) (Ministry of Fisheries and Blue Economy, 2021-04)
    Seychelles, an island group in the western Indian Ocean, comprises of 115 islands spread over an Exclusive Economic Zone (EEZ) of 1.37 million km2. Despite having a land mass of just 455 km2, Seychelles is a large oceanic state, and a major player in the global tuna industry, with Port Victoria one of the busiest industrial fishing ports in the Western Indian Ocean. Seychelles is heavily reliant on its two main pillars of the economy: tourism and fisheries. In view that marine fisheries is such a key contributor to the social, economic and cultural fabric of Seychelles, the fisheries sector plays a central role in the nation’s developmental agenda, from successive National Development Plans to strategies for socio-economic growth. Seychelles has also prioritised the nationalising of the international agenda for sustainable fisheries, such as the Code of Conduct for Responsible Fisheries of the Food and Agriculture Organisation of the United Nations (FAO). There is a widely shared understanding of the need to achieve sustainably managed marine fisheries. But coastal states, like Seychelles, face a complex challenge: ensuring that fishing and fish trade contribute to income, employment, food and nutrition security, while also conserving marine biodiversity for future generations. While there are many aspects to achieve sustainable fisheries, the public availability of information is essential. Transparency does not only contribute to improved decision-making by public authorities, it can also highlight underlying factors of unsustainable fisheries. National authorities, private fishing companies, local fishing communities, investors, retailers and partner countries engaged in fishing agreements stand to benefit from increased transparency. Promoting these positive features of fisheries lies at the heart of the Fisheries Transparency Initiative (FiTI).
  • Economic Impact of the Seychelles Sea Cucumber Fishery and Industry

    SFA Fisheries Economics (Seychelles Fishing Authority, 2021-09)
    1. The Seychelles sea cucumber industry has a non-transferable licensing framework granting access to only 25 fishing and 4 processing licenses. A Total Allowable Catch (TAC) was introduced in 2018 with only three species allowable for fishing: flower teatfish, prickly redfish and white teatfish. The fishing fleet is comprised of 25 vessels embarking on average 6 trips per season and with a mean fishing trip duration of 17 days. Some form of pre-processing is conducted onboard involving eviscerating and salting the sea cucumber. At the processing-level, the 4 licensed processors utilize the entire supply of landings and processes the sea cucumbers to a dried state. Based on the processors’ estimates, the industry’s processing capacity can increase twofold. 2. On a seasonal basis for the 2019/2020 season [October to May], the sea cucumber fishing fleet landed 371,599 pieces of sea cucumbers representing a 34% increase from the 2017/2018 season and a 40% increase from the 2018/2019 season. Flower teatfish had the highest landings (72%) followed by white teatfish (18%) and prickly red (10%). The fleet utilised 99% of the TAC which is an improvement of 28 percentage points compared to the previous season. 3. On an annual basis in 2020, a total of 376,181 sea cucumbers were landed with an estimated landings revenue of SCR 51.9 million. This represents a 78% increase from 2018 and a 22% increase from 2019. Fishers tend to be paid a standard unit price for each specimen, with a SCR 10 commission earned only on the sale of flower teatfish and white teatfish to processors. Increases in ex-vessel prices were observed in 2019, with flower teatfish and white teatfish growing by 25% and 35% respectively. White teatfish garnered the highest ex-vessel price per piece with prices typically SCR 15-20 higher than flower teatfish and SCR 80-110 higher than prickly redfish. 4. Export consignments of dried sea cucumbers are mainly transported via air with Hong Kong as its only destination. Export trends indicate that export is on the rise despite a marginal fall in both the number of pieces and weight by 1% and 4% respectively during 2018-2019. In 2020, data is from January-July and shows that export value has attained an increase of 32% from 2018 and 3% from 2019. Similar to ex-vessel prices, white teatfish is the most valuable specimen exported and in 2020, all 3 species recorded individual highs with white teatfish at SCR 2,295 per kg, flower teatfish at SCR 2,040 per kg and prickly red at SCR 1,020 per kg. Average export prices for white teatfish, flower teatfish and prickly red stands at SCR 1,539, 1,401, 720 per kg respectively. 5. The sea cucumber industry directly supports about 185 jobs generating an income impact of approximately SCR 29.6 million. The fishing component generated the most jobs (150) and income earnings (SCR 23.9 million). Page | 4 There are 118 locals employed in the fishery, resulting to about 143 households directly dependent on the industry, ultimately leading to an estimated 486 individuals impacted to some degree by the industry. 6. The Government through the SFA charges various fees to operators including licensing fees, management fees, and an inspection fee. In 2020, SFA collected SCR 1.8 million in such fees translating to a 18% increase in 2018 and a 15% increase in 2019. 7. In 2019, it is estimated that the mean operational cost for a sea cucumber fishing vessel amounts to SCR 1.2 million, with the main operational cost items being labour remuneration (79%), food (9%), fuel (6%), and accommodation (5%). Vessel owners benefit from a fuel excise tax exemption equivalent to SCR 8.50 per litre. This subsidy reduced fleet-level costs by SCR 1.5 million and lowered the annual operational cost of a vessel by 4%. 8. The industry generated a value-added impact of SCR 43.5 million, with the fishing component and processing/exporting components contributing SCR 31.3 million and SCR 12.3 million respectively.
  • Fisheries Statistical Report Year: 2019

    Seychelles Fishing Authority (Seychelles Fishing Authority, 2020)
    The Seychelles Fisheries Statistical Report is a comprehensive source of information for the commercial fishing industry, fisheries managers, policymakers, and researchers. Since 2014 the report has presented annual updates of fisheries statistics for on a bi-annual basis. The report contains data on the volume of production from Seychelles artisanal, semi-industrial, industrial longline and purse seine fishery by vessel type, species, and geographical locations. Profiles of each fishery, summary of data collection and processing procedures are also provided. Readers should note that data in 2017 SFA implemented a new data management system for artisanal fishery which created delays in data capture and the delays in publication of this report. SFA wishes to apologise for any inconvenience caused by the delay of this publication. Information on recreational, sea cucumber, Lobster and sport fishery is not included in this current edition but will be included progressively in future editions. As a result, the publication gives only a partial estimate of the total volume of local fishery production. Readers should note that some figures presented in this bulletin may be different to previously published because these figures may have been revised following thorough verifications carried out on the data following database upgrading, new data received that were previously missing, revised EEZ shape file used or data validation using VMS data. Also, some of the figures presented may be subject to revision (usually upwards) as more data become available. Since space is a limiting factor in some tables, flag country appearing in these tables is included based on their total catch. The remaining flags are classified under “OTHERS”. Flag countries with only one vessel are automatically placed under “OTHERS” to preserve the confidentiality of data pertaining to the vessel.
  • Report on the Spiny Lobster Fishery: Summary of Fishing Activity for the 2021-2022 season

    SFA Fisheries Research Section - Seychelles Fishing Authority (Seychelles Fishing Authority, 2022-10)
    Spiny lobsters (Palinuridae) are amongst many marine species with great commercial importance for small-scale fisherman. In Seychelles, the spiny lobster has traditionally been managed as a seasonal closure and limited access (license-limited) fishery. The lobster fishing season usually opens for 3 months. This report presents analyses of the fisheries-dependent data collected from the spiny lobster fishery during the 2021/2022 fishing season and makes comparison between previous fishing seasons. To achieve this, data collected from fishers and sampled Catch and Effort logbooks were used. Statistical analyses to compare sizes between the previous seasons for Panulirus longipes (Long-legged spiny lobster) and Panulirus penicillatus (Pronghorn spiny lobster) were performed. Results for 2021/2022 season showed that snorkeling was the predominant fishing method used. A decrease in both the total catch (1.87 MT) and the number of fishing trips (103 trips) was observed compared to the two previous seasons. In terms of fishing sites, Mahé remains the most dominant area for both total catch (1.29 MT) and number of trips (72 trips) amongst the major fishing sites. A decrease in the number of trips (CPUE) was observed. For the 2021/2022 season, female, and male carapace length (CL) size were mostly constant compared to the two previous seasons. Overall, the data analysis for 2021/2022 season indicates that there was a decline in lobster’s relative abundance, most probably attributed to lobster fishing season being open for three consecutive fishing seasons. The CPUE has decreased by 27% compared to the previous season. The 2022 fisheries independent survey will be conducted during the last quarter of the year to establish the changes in the relative abundance of lobsters.
