• The Western Indian Ocean tuna fishery from 1980 to 1985: a summary of data collected by coastal states.

      Lawson, T.A.; Lablache, G.; Simeos, F.; Ali, A.F. (Victoria: Seychelles Fishing Authority, 1986-08)
      A report of data collected by Mozambique, Seychelles and Somalia. As a result of a workshop funded and organised by the FAO/UNDP Indo-Pacific Tuna Programme held at the Seychelles Fishing Authority from 10-24th July 1986 these data have been processed and the statistics reported.
    • Le developpement de la peche thoniere dans l'Ocean Indien face aux ressources.

      Hallier, J.P.; Michaud, P. (Colombo : Indo-Pacific Tuna Development and Management Programme, 1986-11)
      Since 1983, tuna purse seine fishery has increased rapidly in the Indian Ocean. This fishery, being mostly based in Seychelles, represents an excellent opportunity to this country. However, it is essential that a good management strategy be adopted in order to ensure the rational exploitation of the resources. Since this fishery is in its early stage of development, it is not yet possible to obtain an accurate assessment of the stocks based on usual stock assessment methods. Nevertheless, from existing knowledge on the Indian and Atlantic oceans, a preliminary analysis of the resources is attempted. Of the two stocks studied, the skipjack, known as an opportunist species, can support a higher exploitation rate than the yellowfin. It would seem that catches of Indian Ocean yellowfin can be increased, but in view of the lack of knowledge, it would be more reasonable to maintain the actual level of effort in the purse seine fishery.

    • Le crabe girafe Ranina ranina, aux Seychelles: biologie et exploitation

      de Moussac, G. (Seychelles Fishing AuthorityVictoria, Seychelles, 1988)
      Commercial catches of the crabe girafe, Ranina ranina in the Seychelles are analyses. Male crabs are dominant in the catch (65_310= male to 35_310= female) Large individuals present in the catch (exceeding 115mm) are all males. The size at first maturity for female crabs is 89.5mm. One spawning season is observed annually, around December Von Bertalanffy growth estimates obtained from length frequency data using the Hasselblad method to separate the modes followed by modal progressions, are as follows: Males: L oo = 160mm, k = 0.24 per year: Females: L oo = 137mm, k = 0.12 per year. Alternative estimates are also given using the Von, Bertalanffy equation assuming seasonally oscillating growth. The total mortality which corresponds to the natural mortality is estimated as 0.8 for females and 1.0 for males. The crabe girafe fishery in Seychelles waters is described: catch rates seem to be seasonal averaging 0.5 kg/tangle net or 180 kg per fishing day. 18 tonnes of crab were captured from December 1986to March 1988. The relationship between catches and lunar variations is described

    • Artisanal fishing boats in the Seychelles

      Mees, C. C. (Seychelles Fishing AuthorityVictoria, Seychelles, 1989)
      The results of a census of fishing boats on Mahe Praslin and La Digue are presented in total 439 active fishing boats were counted of which 156 were pirogues, 196 were outboards, 68 were whalers and 19 were schooners. The details are discussed in relation to the catch assessment survey conducted by Seychelles fishing Authority. An evaluation of historical data follows. the number of pirogues and outboards increased up to 1986 and declined thereafter. The number of whalers steadily increased since1985 whilst the number of schooners has not changed significantly. It is argued that the changes in boat numbers are a results of interactions between the available near shore and offshore resources, the development of commercial opportunities through the Seychelles Marketing Board, and the effects of fisheries policies towards the promotion of outboard and inboard motors and boats. An assessment of the future boat requirements is presented and discussed in the light of development goals.

    • Activite des embarcations impliquees dans la peche a la ligne a main aux Seychelles.

      Bach, P. (Victoria: Seychelles Fishing Authority, 1989)
      Fishing performances of four different types of boats (pirogues, outboard, whalers, schooners) are studied through the analysis of the temporal evolution, between July 1985 and June 1988, for four parameters: numbers of active fishing boats,- total number of fishing trips, - average number of trips/boat, - average trip duration. The trends from these analysis reveals that the boats involved in the handline fishery in seychelles have evolved considerably. These changes must be taken into consideration in the case of an eventual reorganisation of the fleet.
    • Seychelles schooner fishery: an analysis of data collected during the period January 1985 to July 1990

      Mees, C. C. (Seychelles Fishing AuthorityVictoria, Seychelles, 1990)
      Schooners are the largest category of vessel participating in the local fishery. They are fully decked fishing boats equipped with inboard engines and fish with handlines or electric fishing reels. They account for about 15% of the total artisanal catch, but commercially valuable demersal species predominate. Their economic importance is thus greater than the catch volumes would indicate. Furthermore, they have the greatest range and are able to undertake longer fishing trips than other local vessels. They, or a similar class of vessel, are thus considered vitally important for the future development of the local fishery, where the potential for expansion from demersal species is considered to be offshore on the more distant banks and island groups. The potential yield of demersal species available to the line fishery is estimated to be 3,800 MT. Despite efforts to promote the schooner fishery the number of boats actively fishing has declined in recent years. The fleet is considered to be run down and to offer poor financial returns on investment. Recently, in an attempt to rejuvenate the fishery, new boat designs and electric fishing reels have been introduced, and policy changes have been proposed to encourage new investment in this sector. The present report examines the impact of some of these changes.
    • Analyse des donneés collecteés lors des embarquements à bord des senneurs basés aux Seychelles (1986-1989)

      de Montaudouin, X.; Hallier, J.-P.; Hassani, S. (Seychelles Fishing AuthorityVictoria, Seychelles, 1990)
      The tuna purse seine fishery based in Seychelles is analysed using data collected by observers on board French, Spanish, Japanese and Soviet vessels. From 1986 to 1989, diffferent types of data were recorded such as meteorolical and oceanographic parameters, aspects and sizes of schools sighted, seiner activities, fishing characteristics (catch, yield, duration of fishing sets). Reliability of observers data with respect to catches is assessed by comparison with log data from French purse seiners.
    • Seychelles artisanal fisheries statistics for 1989

      Mees, C. C. (Seychelles Fishing AuthorityVictoria, Seychelles, 1990)
      1. During 1989 an estimated total of 4,391.7mt of fish was landed on Mahe, Praslin and La Digue by 390 fishing boats, (including sport fishing boats), 81.2% of which was landed on Mahe alone. The volume of catch does not differ significantly from 1988, but the number of boats has decreased, being a decrease in the number of small boats and schooners, whilst whalers using handlines have increased. 2. The most important species groups landed (greater than 5% of the total catch) were carangues (32.0%), job (9.6%), red snapper (9.1%), capitaine (7.0%), maquereau doux (6.7%), and trap fishes (cordonier 5.6%, others 5.0%), and bonite (5.3%). 3. The variation in monthly landings was not as pronounced as in previous years. Peak landings occurred in April (430.1mt), May (446.6mt) and November (471.7mt). The lowest catch was recorded during July (263.4mt), during the period of S.E trade winds. The average catch per month was 366mt. 4. Species variation in the catch was apparent with pelagic fish (including bonite) tending to represent a greater proportion of the catch during the period of S.E Trades (May-September); and demersal fish (red snapper, vieilles, and to a lesser extent, job) being greater during the period January - May and October - December. Carangues were greater in the catch during April - June and November. Trap fishes did not show much variation but tended to be greater during January - February and August - October, capitaines peaked in the catch between July and September, whilst maquereaux were caught in the early and latter parts of the year with a distinct peak in September. Much of the variation observed, particularly the inverse relationship exhibited by pelagic and demersal fish may not represent seasonal variations in catchability of the fish, but rather changing fishing strategies during the different monsoon periods. 5. By landing site, Victoria was the single most important site accounting for 37.6% of the total. Other important sites were: Anse Royale Market (7.3%), Belombre (6.9%), and Anse Boileau (3.9%) on Mahe; Baie St. Anne/Cap Samy (4.0%) and Flying Dutchman/Grand Anse (3.5%) on Praslin, and on La Digue, La Passe (2.6%). Whalers accounted for a large part of this catch, and considering the small boats only (on foot, pirogues, outboards) the most important sites were Belombre (7.4% of small boat catch), Bougainville (6.6%), Pointe Conan (5.8%) Glacis (4.6%), La Retraite (4.5%) and Anse Aux Pins (4.2%) on Mahe, whilst on Praslin and La Digue where there are fewer whalers the rank order of importance does not change. 6. Trap fishes dominate the catch on Praslin and La Digue whilst carangue are most important on Mahe. This reflect the predominance of the small-boat fishery on Praslin and La Digue. 7. In total, the small-boat fishery accounted for 39.5% of fish landings during 1990: fishermen on foot, 0.6%; pirogues, 5.3%; outboards, 33.1%; whalers with traps, 0.5%. Fishermen on foot landed mostly octopus (72.9% of landings); pirogues landed trap fishes (43.7%) and maquereaux (21.1%); outboards landed maquereaux (32.1%), trap fishes (23.2%) and carangues (19.1%) whilst whalers with traps landed almost entirely trap fish (81.0%). Demersal fish formed only a minor part of the landings by the small boat fishery. 8. The whaler-handline fishery accounted for 46% of total landings. An average of 78 whalers operated each month during 1989 showing an increase of 13 boats since1988, whilst the catch landed was slightly less than 1988. Carangues accounted for the largest part of the landings (42.6%). Other important species were job (10.9%), red Snapper (10.0%), other carangues (9.6%), bonite (7.6%), capitaine (5.5%) and becune (5.5%). 9. An average of 16.2 schooners operated each month during 1989 and accounted for 14.2% of total landings. Although the number of boats decreased by 4.8 on average, the catch was significantly greater than during 1988. Bourgeois was the single most important species caught (19.0%) followed by job jaune (16.0%), job gris (8.9%), lascar (7.8%), vara vara (7.5%), vieille maconde (6.7%) and vieille platte (5.1%). The spanner crab, Ranina ranina accounted for 2.8% of schooner landings. The larger proportion of the catch landed by schooners during 1989 may reflect the use of electric reels on some boats, increasing their efficiency. 10. An average of 4 sport fishing boats accounted for 0.3% of total landings. Bonite (43.1%), sailfish (37.8%), wahoo (8.9%) and dorade (5.1%) were the most important species. 11. Fish purchases from the Artisanal Fishery by Seychelles Marketing Board (SMB) were equivalent to 29.8% of total landings (1308.7 mt). 67.5% was purchased through the 8 SM8 centres on Mahe and 32.5% through the 3 centres on Praslin and La Digue. Victoria was the single most important centre (50.4% of all purchases), followed by Anse La Mouche (9.2%) on Mahe. The Baie St Anne (12.1%) and La Passe (13.4%) centres on Praslin and La Digue respectively also accounted for a substantial volume of purchases. The least important centre was Cascade (0.2%), that at La Retraite already having ceased to function. The major species purchased were job (20.9%), red snappers (18.9%), vieille (14.7%), capitaines (8.8%) and carangues (8.7%). 12. S.M.B also purchased 272.6 mt of frozen fish (gutted and ungutted) from foreign longline vessels during 1989. Species purchased were all pelagic of which yellowfin was the most common (38.2%), followed by sailfish (18.8%), kingfish (5.7%) and marlin (5.5%). 13. Total exports (excluding tuna transhipped through Seychelles or through the cannery) amounted to 707 mt, 37% being fresh and 63% frozen, valued at SER 14.2 million (CIF). This represent an increase of 132.4 mt since 1988. Major destinations for the fish were Reunion (79.3%), England (10.4%), and France (2.9%). Job (25.6%), red snapper (24.1%), and maconde (19.1%) formed the most important fresh fish exports, whilst red snapper (31.0%), job (20.5%), and capitaine (20.4%) were the important frozen fish species. 14. A comparison of data collected between 1985 and 1989 follow. Data prior to 1985 are reported in the Artisanal Fisheries Statistics for 1985.
    • The fishermen of Seychelles: Results of a socio-economic study of Seychelles fishing community

      Mees, C. C. (Seychelles Fishing AuthorityVictoria, Seychelles, 1990)
      OBJECTIVES: The present study was conducted to evaluate the socio_economic status of Seychelles fishing community in order to provide a foundation for formulation of rational management and policy decisions relating to the artisanal fishing sector. ANALYSIS: The data generated were analysed by boat - type, and by analytical strata thus: Crew, All skippers, skipper-owners with a loan, skipper-owners without a loan, share skippers (non boat owners). SURVEY COVERAGE: 300 interviews were conducted on the islands of Mahe, Praslin and La Digue, of which 112 were crew members and 188 were skippers. It was estimated that the skippers of 60.3% of all full-time fishing boats were interviewed. The coverage was greater for schooners (100%) and whalers (71.6%) than outboards (57.2%) and pirogues (45.5%). In relation to the number of men rather than boats, it was estimated that up to 1000 people may be fishing on a casual basis, but that the true number of ‘commercial’ fishermen is in the range 475-640, giving a survey coverage of 47%-63%. This number represents approximately 2.7% of the entire working population. Agriculture, forestry and fisheries account for 8.1% of the working population, of which 62.6% were farm workers, 3.8% worked in forestry, and 33.6% were fishermen or marine rangers.
    • The development of the lobster fishery in the Seychelles

      Bautil, B.R.R. (Seychelles Fishing AuthorityVictoria, Seychelles, 1991)
      Two different groups of lobsters are of commercial importance in the Seychelles: spiny lobsters and slipper lobsters. The spiny lobsters are: Panulirus penicillatus, Panulirus longipes, Panulirus versicolor and Panulirus ornatus. Fishing for spiny lobster in Seychelles is a traditional activity in the shallow waters surrounding the main granitic Islands. Fishing is conducted at night by skin divers operating with lights. Following the development of the tourist industry during the seventies the local demand for lobsters increased to several tonnes a year. After being open for many years, the fishery was closed from 1983 to 1989. The fishery was reopen from December 1989 to May 1990, during which time an estimated 10 tonnes of spiny lobsters were supplied to the local market. The regulations for lobster fishing included: a closed season from the 1st May to 30th of September; a minimal size of 7,5 cm cephalothoracic length; a ban on the catching of berried females; no fishing was allowed in marine parks and reserves; and all lobsters had to be sold alive to one company (SMB). Subsequently, the fishery was closed again due to abuse of the regulations. Since the closure, 15 tonnes of frozen lobsters per year were imported from Singapore, representing an expenditure of 225.000 US$. The imported lobsters are of the same species as the local one. In September 1991, a lobster survey began, to better assess the resource on the granitic areas of the Mahe plateau. It is anticipated that if limited to the granitic areas a well managed artisanal fishery will not supply 15 tonnes a year to the local market. It is therefore recommended that the lobster artisanal fishery be developed in the outer Islands. One of the main constraints of that development is a problem of quality control. It is felt that this constraint could be overcome by using the right preservation methods and by organizing training course. A research survey in the Amirantes is proposed in order to better assess the resource and assess the development possibilities.
    • A mothership dory fishing operation in Seychelles: results of the first voyage of the locally owned vessel Pecheur Breton, March - May 1991.

      Mees, C. C. (Seychelles Fishing AuthorityVictoria, Seychelles, 1991)
      A Mother ship dory fishing operation was conducted in Seychelles waters by the vessel Pecheur Breton and 11 catcher boats during 1991. This venture was carried out over a 72 day period from 2nd March 1991 to 14 May 1991 and 246 tonnes of fish were caught.

    • Pêcheur Breton : An analysis of data relating to a Mothership Dory fishing operation in Seychelles Waters from March 1991 - June 1992

      Mees, C. C. (Seychelles Fishing AuthorityVictoria, Seychelles, 1992)
      This report presents analyses of data for Trips 2, 3 and 4 undertaken by the mothership - dory fishing venture of Pecheur Breton. Trip 1 was described separately (Mees, 1991). A comparison of data for the 4 trips follows. Trip 2, from 22 October 1991 - 16 December 1991 targeted stocks at the SE edge of the Mahe Plateau (25 days), the banks South of the Plateau (12 days), Amirantes (5 days), Platte (1 day) and the Providence / Farquhar group (12 days). 665 dory fishing trips landed 248.86 tonnes of fish of which 85.4% were demersal species. The mean catch rate was 12.76 kg/man-hour. Trip 3, from 8 January 1992 - 12 March 1992 fished for 28 days in the Amirantes, 22 at the banks South of the Mahe Plateau, 5 on the SE edge of the Mahe Plateau and 2 days at Junon Bank. 169.7 tonnes of fish were landed during 651 dory fishing trips, and the mean catch rate was 9.14 kg/man-hour. 86.2% of the catch was demersal species. Trip 4 took place between 18 April and 5 June 1992 and was confined soley to the Providence / Farquhar group of islands. 558 dory fishing trips were recorded and landed 231.3 tonnes of fish. However, there were 5 days without an observer and the total landings were estimated to be 262.3 tonnes. The mean catch rate was 15.87 kg/man-hour, significantly higher than the other locations nearer to Mahe. Demersal species formed 92% of the catch. In total, the four trips undertaken to date by Pecheur Breton have landed 926.9 tonnes of fish of which 86.9% were demersal species. The most important species landed were Batrican (27.4% of the total), Capitaine Rouge (16.7%), Vara vara (9.1%), Job gris (8.7%), and Vielle platte (5.0%). However, species composition varied by depth and by location. As depth increased the proportion of Lethrinids (capitaine) decreased and Serranids (Vielle) increased. Lutjanids (snappers and job) remained constant but on closer examination it is seen that with increasing depth Batrican increased whilst Job Gris and Vara vara decreased. At the greatest depths Etelis spp. predominated. By location, Lutjanids predominated everywhere except Providence / Farquhar where Lethrinids were the most abundant. When fishing depth was 70m or more Batrican was the most common Lutjanid, but at lesser depths it was Job Gris, Vara vara or Bourgeois. The latter, however, was only the most common fish at one location.
