  • Phytoplankton variables dynamics in the Halda River (Bangabandhu Fisheries Heritage), Chittagong, Bangladesh

    Islam, Md.S. (2021)
    The Halda is a river ecosystem of major importance, well-suited for the natural spawning of major carps due to the unique physicochemical and biological properties of its water. The productivity of the Halda ecosystem mainly depends on the plankton density. The present study has been aimed at the determination of qualitative and quantitative density of the phytoplankton in the Halda River during a two-year period extending from January, 2017 to December, 2018. Phytoplankton density is a good indicator of the water quality of a river ecosystem. A total of 74 species of phytoplankton divided into 47 genera belonging to 6 phyla has been recorded. Bacillariophyta was the most dominant phylum of phytoplankton followed by Cyanobacteria, Chlorophyta, Miozoa, Charophyta, and Euglenozoa. The maximum phytoplankton density was recorded during the pre-monsoon period, and its minimum fell upon the post-monsoon period. The phytoplankton showed a positive significant relationship with transparency, total dissolved solids, conductivity, calcium, total hardness, and BOD5 and an inverse significant relationship with water temperature. The water of the Halda River is organically polluted and eutrophic in its nature.
  • Водные биоресурсы и среда обитания. Том 4, вып. 2

    Bragina, T.M. (Azov-Black Sea Branch of the FSBSI “VNIRO” (“AZNIIRKH”)Rostov-on-Don, Russia, 2021)
    Chlorophyll-α in the Azov Sea has been studied according to the data of remote sensing of the Earth collected in 2006–2019. Biology and spatial distribution of roach Rutilus rutilus heckelii and common bream Abramis brama juveniles in the Don River have been characterized for the period of 2020. Abiotic environmental factors in classification of the water from energy facilities have been investigated for aquaculture purposes. Reproduction results of the semi-anadromous fish species at the floodplain spawning and rearing farms (hatcheries) of the Azov Sea and Kuban River region have been summarized for 2020. Preservation techniques for zostera (eelgrass) washed ashore as storm debris are described. Long-term dynamics of the bream stocks in the Azov Sea (Russian waters) has been tracked based on the results of CMSY modeling under the conditions of limited data availability (2002–2020). Possibilities of the short-term forecast of the catch of the European sprat from the Black Sea stock off the western coast of Crimea are suggested.
  • Book Abstract "Physiological and genetic aspects of so-iuy mullet Planiliza haematocheila (Temminck & Schlegel, 1845) biology in the Azov and Black Sea Basin"

    Azov-Black Sea Branch of VNIRO (2021)
    This work characterizes the physiological status of so-iuy mullet Planiliza haematocheila (Temminck & Schlegel, 1945) upon formation of its broodstock at the beginning of its acclimatization (1979–1983) in the Azov and Black Sea Basin. Following the results of a long-term investigation, age-length, seasonal, and annual dynamics of physiological parameters have been identifi ed, as well as specifi c features of so-iuy mullet metabolism and reproduction.
  • Possibilities of short-term forecasting of the catch of the European sprat from the Black Sea stock off the western coast of Crimea

    Panov, B.N.; Spiridonova, E.O. (2021)
    This research work presents the results of the analysis of the data collected during the multimethod monitoring of the European sprat fishing (the Black Sea stock) off the western coast of Crimea in July–September, 2019. The monitoring was aimed at identification of a relationship between the behavior of biological resources and their environmental conditions with the purpose of developing the methods of short-term forecasting of fishing efficiency. Graphical and correlation analysis of the daily data on vessel catches and sea surface temperature, as well as satellite altimetry data and characteristics of atmospheric transfers in the fishing area made it possible to suggest an environmental mechanism for the formation of commercial sprat aggregations in the investigated area. During its summer feeding in the coastal waters, sprat forms denser aggregations under the influence of synoptic anticyclonic vortices that develop near the shelf. Intensification of those aggregations is associated with an increase in the western atmospheric transfers in this region. Southern currents, uncharacteristic for the investigated area, and a decrease in the temperature of surface waters in the coastal zone indicate escalation of the stable impact of anticyclonic vortices on the coastal waters. The presence of statistically significant anticipatory relationships between average daily fishing pressure and abiotic factors holds a promise for the possibility of short-term forecasting of the sprat fishing efficiency off the western coast of Crimea in the summer season with the forecast interval equaling 1–7 days.
  • Long-term dynamics of the bream stocks in the Azov Sea (Russian waters) based on the results of CMSY modeling under the conditions of limited data availability (2002–2020)

    Cherednikov, S.Yu.; Piatinskii, M.M.; Kozobrod, I.D. (2021)
    Analytical assessment of the Azov Sea stock of the common bream Abramis brama (Linnaeus, 1758) for the time range 2002–2020 has been performed using CMSY trend model in R that is suitable for application in the context of limited data availability. Current state of the stock is at the level of the reference point based on stock biomass, and shows evidence of substantial overexploitation (B2020/BMSY=0.989; F2020/FMSY=1.82). Accounting for the volumes of IUU-fishing using indirect estimates increases comprehensiveness of the results and ensures adequate stock assessment and evaluation of fishing mortality. Pooled estimates of bream stock biomass for the investigated period indicate a collapse of population abundance that fell upon 2005–2013 and, presumably, stemmed from climatic and hydrochemical changes in the Azov Sea environment, not being associated with overexploitation of the population in those years. At present, the bream population still remains in depressed state, with prerequisites for stock recovery. Following the results of modeling and after a consideration of forecast scenarios, the size of recommended legal catch for 2022–2023 could be set within the range between 40 and 110 t, depending on the efficiency of control, accounting, prevention and suppression of IUU-fishing. So long as the population is exploited within these limits, stock biomass will remain at a safe level and has the possibility of reaching 950 t. The results of this investigation highlight the necessity of control and prevention of bream IUU-fishing in the Azov Sea and Don River Basins; this is a crucial factor influencing bream population in the recent years.
  • Preservation techniques for zostera (eelgrass) washed ashore as storm debris

    Bogomolova, V.V.; Belyakova, I.A.; Esina, L.M.; Chernyavskaya, S.L.; Krivonos, O.N. (2021)
    The results of organoleptic evaluation of seagrass Zostera marina (eelgrass) storm debris are presented. The chemical composition of Zostera during its mass aggregation along the wrack line of the Black Sea coast in the spring and summer seasons of 2020 has been investigated. The safety of Zostera storm debris for consumption has been evaluated based on such indicators as content of radionuclides and toxic elements, and microbiological characteristics. Preservation of the storm debris samples has been conducted using the following techniques: drying under natural conditions (average daily air temperature 19–25 °С, wind velocity 5–8 m/s, atmospheric humidity 56.5–80.0 %, height of a storm debris layer 5–10 cm), artificial drying (forced ventilation at 40±2 °С, layer height 5–10 cm), and salting (using dry method with addition of table salt in the amount equal to 20 % of the weight of macrophytes). Organoleptic properties of dried and salted eelgrass under various storage times are described. It has been established that the eelgrass, inhabiting the Azov and Black Sea Fishery Basin and washed ashore, contains from 16.9 to 25.7 % pectic substances, which indicates high value of this macrophyte. A method of preservation does not severely affect the content of pectic substances. Recommendations on eelgrass preservation by means of drying (both under natural and controlled conditions) and salting have been given to ensure the highest possible retention of its quality.
  • Reproduction results of the semi-anadromous fish species at the floodplain spawning and rearing farms (hatcheries) of the Azov Sea and Kuban River region in 2020

    Khorosheltseva, V.N.; Gorbenko, E.V.; Poluyan, A.Ya.; Medvedeva, A.A.; Voloshina, M.V. (2021)
    Long-term observations over floodplain spawning grounds reveal the decrease in reproductive efficiency of zander (pike-perch) (Sander lucioperca, Linnaeus, 1758) and roach (Rutilus rutilus heckelii, Nordmann, 1840), resulting from deterioration of hydrological and hydrochemical regimes. Due to its low water content, the year of 2020 has been recorded as most unfavorable for the reproduction of semi-anadromous fish species. This article considers the results of 2020 spawning migration at the spawning and rearing farms of a floodplain type (Beysug Hatchery and Yeysk Experimenal Hatchery). In the spring season of 2020, these two farms reached planned stocking amount of breeders. The best age, length and weigh characteristics were exhibited by the roach breeders entering the water bodies of Yeysk Experimenal Hatchery for spawning. At Beysug Hatchery, the quality of breeders belonging to the semi-anadromous fish species was at its average long-term level. Despite substantial entry of breeders to the water bodies of Yeysk Experimental Hatchery, abundance of the roach juveniles migrating down to the Azov Sea was almost 9 times lower than average long-term values, and for zander juveniles this value was 3 times lower. In Beysug Hatchery, due to low water content, abundance of zander juveniles during their downward migration was 22 times lower (in a long-term context).
  • Abiotic environmental factors in classification of the water from energy facilities for aquaculture purposes

    Kalayda, M.L.; Gordeeva, M.E. (2021)
    This article proposes a water classification that is based on the means and practices of water supply to energy facilities with regard to the temperature parameter and accounting for the prospective possibility of using such water for the purposes of aquaculture. This water classification relies on physicochemical characteristics of water: temperature, pH, dissolved oxygen concentration, redox potential, and total antioxidant activity. The collection of the data on the actual status of abiotic environmental factors was conducted at natural water bodies, including the ones used for cooling purposes by the energy facilities of the Republic of Tatarstan, from 2010 to the present time. Based on the temperature parameter, three water classes have been distinguished: 1) with the physicochemical characteristics typical for a water body of that geographical location; 2) water of the water bodies used for cooling purposes by energy facilities with the presence of zones of increased temperatures; 3) water of cooling ponds. This investigation has revealed that the waters are characterized by a complex structure involving different sets of physicochemical characteristics. It is shown that three distinguished water classes are characterized by certain sets of values of the Water Structure Index (5–7, 2.7–3.2, and 9–16, respectively) and redox potential (in the range of 2.47 unitsEh, 2 unitsEh, and 3.43–4.5 unitsEh, respectively). For these classes the following types of uses in aquaculture are most applicable: 1) cultivation of fish species native for this fish farming area; 2) cage farms, including the ones with multiple cycles of production; 3) cultivation of phytovorous fish species in the overgrown and blooming environment.
  • Biological characterization and spatial distribution of roach Rutilus rutilus heckelii and common bream Abramis brama juveniles in the Don River in 2020

    Piatinskii, M.M.; Kozobrod, I.D.; Cherednikov, S.Yu.; Zherdev, N.A. (2021)
    The data collected during the scientific monitoring of the spawning run of roach Rutilus rutilus heckelii and common bream Abramis brama in the Don River have been analyzed. Investigation of the biological characteristics, spatial distribution and specific features of the downward migration of fish juveniles was carried out in the Lower Don area stretching from Romanovskaya Settlement to the Don River Delta in May–October, 2020. The obtained results show significant gain in average length and weight of roach and bream juveniles in the spring – summer season of 2020 and its absence in the summer – autumn season, which was caused by the downward migration of the partially grown juveniles in the Taganrog Bay. Hauls of fry drag nets showed that the juveniles in the investigated water bodies kept to the shallow coastal waters. Quantitative assessment of the spatial distribution of juveniles indicates spatial heterogeneity of their aggregations and moderately productive spawning run in the context of low water content in 2020. Based on the outcomes of the scientific monitoring, the abundance of roach juveniles was assessed to be 49.3 million ind., and for bream juveniles it equaled 30.4 million ind. In the future, the research results factoring in statistical processing will make it possible to analyze the long-term dynamics of the biological characteristics of roach and bream juveniles.
  • Assessment of water quality in small rivers of the Seversky Donets and the Tuzlov River Basins using biotic indices

    Bakaeva, E.N.; Taradayko, M.N. (2021)
    The restructuring of the coal mining industry, which began in the 1990s, has impacted the environmental situation in Eastern Donbass within Rostov Region rather adversely. Aquatic ecosystems of rivers with low water content and, consequently, low dilution capacity are characterized by high susceptibility to anthropogenic impact. Samples of macrozoobenthos were taken in the areas with different anthropogenic load in 18 sections of small rivers of the Seversky Donets and Tuzlov River Basins: the upper reaches, the places downstream of mine drainage water outlets, and mouths. Based on a comparison of the values of the Woodiwiss, Parele, Goodnight–Whitley, and Mayer biotic indices, sections with different levels of water pollution have been identified in these three areas. Water was characterized as “clean” in 47 % of the sections according to the Goodnight–Whitley index, and in 27 % according to the Parele index. The greatest overlap in the estimation of water pollution level according to these indices was in the “polluted” category. Altogether 62 % of the river mouth waters, 50 % of the sections located downstream of mine drainage water outlets, and 17 % of the upper reaches are attributed to this level of pollution. According to all water indices, most of the sections are classified as “polluted”, although there is a difference. Thus, 94 % of the sections were “polluted” according to the Mayer index, 89 % of them according to the Woodiwiss index, 47 % according to the Parele index, and only 33 % of the sections were identified as “polluted” according to the Goodnight–Whitley index. The discrepancy in estimation of water pollution by biotic indices has been found in five cases out of eighteen investigated stations. The final score has been assigned according to the index with the most negative result. For Eastern Donbass area, taking into consideration the class of small rivers, their zoological and geographical characteristics, the consequences of restructuring the coal mining industry, and agricultural nature of this region, biotic indices should be considered as indicators of organic water pollution along with the abundance, biomass, and number of the macrozoobenthos taxa.
  • Chlorophyll-a in the Azov Sea according to the data of remote sensing of the Earth in 2006–2019

    Kochergin, А.T.; Kriskevich, L.V. (2021)
    Based on satellite images of the sea surface, chlorophyll-α content in different areas of the Azov Sea in 2006–2019 has been estimated for several timeframes: its minimum, spring and summer–autumn peaks. The areas and timelines of the main pronounced and secondary peaks of chlorophyll concentration, its decline and the lowest point of its development are presented. During the investigated period, chlorophyll-α concentrations in the context of the spring population explosion were predominantly lower than 20 mg/m3, except for the central part of the sea and its eastern areas, where, in certain years, the content of this pigment reached 50 mg/m3. Particularly low concentrations of chlorophyll-α in spring were observed after 2013; they did not exceed the value of 16.5 mg/m3 in any area. A pronounced spring explosion mainly fell upon April and May, with its secondary weaker case in January – March, especially in the eastern and southeastern parts of the sea through the recent decade. The summer–autumn peak of chlorophyll-α content was characterized by increased concentrations: up to 40–50 mg/m3 in the northern, central and eastern parts of the sea until 2014, and up to 20 mg/m3 throughout the entire area since then. The summer–spring peak of chlorophyll-α concentration stretches predominately from June to September, and there exists the second peak in some areas. Second peak is less pronounced and falls upon October – December. In the course of the observation period, the minimum of chlorophyll-α content was decreasing from 10.0 to 4.0 mg/m3 throughout the entire sea area. The minimum was recorded mostly during the following months: October – February for the western parts of the sea, and November – March for the central and eastern parts. It is possible that the negative trend in chlorophyll-α content could be induced by salinization and changes in the biotic structure of the sea.
  • Assessment of water and bottom sediment pollution with heavy metals and arsenic in the Caucasus Region of the Black Sea at the present time

    Evseeva, A.I.; Korablina, I.V.; Gevorkyan, Zh.V.; Katalevsky, N.I.; Gorgola, L.G.; Bragina, T.M. (2020)
    The content of nine heavy metals (Fe, Mn, Zn, Cr, Cu, Pb, Cd, Hg, Ni) and arsenic in the water and bottom sediments of the North-Eastern Black Sea at the present time (2018–2019) has been estimated, and the results of this investigation are presented. The analyses of samples, collected during the multi-purpose expeditions of the Azov-Black Sea Branch of the FSBSI “VNIRO” (“AzNIIRKH”) in the spring – early summer and summer – early autumn seasons, are summarized. Altogether, 204 water samples and 60 bottom sediment samples have been collected. Estimation of mass concentrations of heavy metals and arsenic has been conducted according to the methods, developed and adopted by the Azov-Black Sea Branch of the FSBSI “VNIRO” (“AzNIIRKH”). Pollution levels in the habitat of aquatic living resources have been assessed based on the standards for maximum allowable concentrations (MAC) of harmful substances in water bodies of fisheries importance and on the average long-term values. In some areas, subjected to the increased anthropogenic pressure, exceedance in MAC of iron, manganese, zinc, and nickel is recorded. It is shown that, at present, the revealed content of heavy metals and arsenic in the water and bottom sediments of the investigated area of the Caucasus Region of the Black Sea does not pose a threat for the aquatic living resources.
  • Specific features of the change in the statistical characteristics of the horizontal structure of the salinity field of the Azov Sea waters

    Panov, B.N.; Spiridonova, E.O.; Bragina, T.M. (2020)
    The work is based on the data from 49 spring, summer and autumn oceanographic surveys carried out by the Azov-Black Sea Branch of FSBSI “VNIRO” (“AzNIIRKH”) in the Azov Sea from 2001 to 2016. As characteristics of the horizontal structure of the salinity field, the radii of the concentration region of the spatial correlation function of the field in the zonal and meridional directions in the surface and bottom horizons were calculated, as well as their ratio reflecting the prevailing direction of water exchange. The average size of meridional radii was 42 km, and for the zonal one it was equal to 46 km. It is shown that, in the surface layer, the radii are maximum in summer and minimum in spring; in the bottom layer they decrease mainly from spring to autumn. The zonal radius prevails in the surface layer of the sea, whereas the meridional one prevails in the bottom. In the trends of long-term changes in the surface layer, the sizes of the meridional radii have increased. In the bottom layer, the zonal radii were decreasing. The years of predominance of zonal radii in the structure of the salinity field were attended with a decrease in the average salinity of the sea, and the predominance of meridional radii was associated with its increase. An almost complete absence of statistically significant relationships between the characteristics of the field, both in seasonal and in average annual values, was noted.
  • Status of the Chamelea gallina and Pitar rudis communities in the North-Eastern Black Sea in the autumn of 2019

    Frolenko, L.N.; Zhivoglyadova, L.A.; Bragina, T.M. (2020)
    Spatial distribution and quantitative characteristics of the main bottom communities in the North- Eastern Black Sea, characterized by the prevalence of the native bivalve species Chamelea gallina and Pitar rudis, have been considered for the autumn season of 2019. Within the investigated region, at the depth of 18 m,the largest area of sandy biotopes with silt and shell admixture was occupied by a community dominated by the bivalve mollusc Ch. gallina. At the depth of 30 m, a community of the pelophilic bivalve mollusc P. rudis was observed on silty substrate with shells and, at times, sand admixture. In the Chamelea community, molluscs were the most prominent group in terms of abundance and biomass. In the Pitar community, polychaetes were the most abundant in the benthic community, while molluscs prevailed in terms of their biomass. If compared with the data of the 1960s, the contemporary analysis of the materials presented indicates a decrease in the biomass of the macrozoobenthos down to 93 g/m2 and of the dominant species down to 41 g/m2 in the Chamelea community, which is associated with the predominance of small individuals in the mollusc populations. In the autumn of 2019, despite the appearance of invading species, the native species prevailed in the main regional biocoenoses.
  • Dynamics of water quality in the Temernik River considering the toxicity levels based on the data of the biotest battery

    Bakaeva, E.N.; Taradayko, M.N.; Ignatova, N.A.; Zaporozhtseva, A.Yu.; Bragina, T.M. (2020)
    The urbanized section of the Temernik River (Rostov-on-Don, Southern Federal District) is subjected to anthropogenic pressure. During the investigation of water toxicity by means of the bioassay method, an obvious disadvantage of using one biotest was revealed. Recently, a biotests battery has been used. However, assessing toxicity based on only one, most sensitive biotest, is untenable. The toxicity assessment has been carried out according to the scale developed by the authors. The scale considers the results of the assessment of toxicity level according to each biotest, and classifies water quality in concordance with the classes adopted in hydrochemistry. The water quality of the Temernik River has been assessed by means of the bioassay method according to a set of practices, taking into account the toxicity levels for each of the applied biotests. The studies were carried out in 2017–2019. The cultures of Chlorella vulgaris, Raphanus sativus (phytotest), and Daphnia magna were used. The water of the Temernik River showed a wide range of toxicity from “low” toxic (2 “a” class) to “extremely” toxic (5 class). The dynamics of water quality was characterized by the increase in toxicity from 2017 to 2019. The highest degree of water toxicity was recorded at the mouth of the Temernik River, in the Don River downstream from the mouth of the Temernik River, and near the Botanical Garden of the Southern Federal University at the storage site for extracted bottom sediments. Biotest data are confirmed by the analytical data on water pollution.
  • Assessment of caesium-137 accumulation in the bottom sediments and aquatic bioresources of the Azov Sea at the present time

    Mkhitaryan, I.D.; Korablina, I.V.; Bragina, T.M. (2020)
    The results of radioecological investigation of the bottom sediments in the Azov Sea are given for 2017–2019. Pollution of the Azov Sea bottom sediments during the period under study has been detected sporadically and is determined by redistribution of predominately post-Chernobyl fallout. The level of caesuim-137 pollution of the bottom sediments has been evaluated in comparison with its long-term average values. The results of monitoring of radiocaesium content in the main commercial fish species of the Azov Sea are presented for the same period. Comparison of caesium-137 content in the fish muscle tissues according to the sanitary and epidemiological regulations and standards, currently in force in the Russian Federation, is made. It is shown that the content of caesium-137 in the aquatic biological resources of the Azov Sea is much lower than the maximum permissible content of this isotope in fish and does not pose a radiation threat. For the investigated period, the state of the Azov Sea environment in terms of radiation does not give cause for concern pertaining to the accumulation of caesium-137 isotope. Radioecological monitoring of the Azov Sea area in 2017–2019 has revealed that Chernobyl trace remains the main source of radiation pollution.
  • Characterization of the allometric growth of soft-shell clam (Mya arenaria Linnaeus, 1758) in the Southern Azov Sea

    Zolotnitsky, A.P.; Sytnik, N.A.; Bragina, T.M. (2020)
    Allometric growth in the soft-shell clam, or sand gaper (Mya arenaria L.) population, inhabiting the Southern Azov Sea, is investigated. Quantitative characterization of relationship between the height (H, mm), depth (D, mm) and length (L, mm) of the shell of this mollusc, as it is based on the equations of linear (Y=a+b·X) and power (Y=a·Xb) functions, is presented. Shell shape parameters in the process of soft-shell clam growth, namely, elongation (H/L), and sagittal (D/L) and frontal (D/H) curvatures, have been studied. The relationship between mollusc length and its live body weight (W, g) is identified; it is approximated by a power function with the coefficient of proportionality (a) 1.64·10-4 and the coefficient of regression (b) 2.90. By means of the linear function, the new data on the relationship between shell weight (Wr), wet (Wm) and dry (Ws) weight of soft tissues, liquid held in the mollusc mantle (Wmj), siphon weight (Ws) and the total (live body) weight of soft-shell clam have been obtained. It is shown that several morphological characteristics of this species inhabiting the Azov Sea are similar in terms of their parameters to the ones of soft-shell clam populations in the White and Baltic Seas, although there exist certain distinctions.
  • Estimation of the meat yield of veined rapa whelk during its processing

    Esina, L.M.; Gorbenko, L.A.; Bragina, T.M. (2020)
    Technological standardization of the product yield after processing of aquatic bioresources is conducted to facilitate their rational management and the control over their exploitation; it also provides the means to plan out the product output and consumption of raw materials. At present, the standards for wastes, losses and meat yield are absent for the processing of a major fishing target in the Azov and Black Sea Fishery Basin, namely, veined rapa whelk Rapana venosa. In this article, the results of development and control work on standardization of wastes, losses and meat yield for veined rapa whelk, conducted in the processing environment and in the laboratory setting, are presented. The yield of veined rapa whelk meat was assessed as a proportion of the total weight of raw material incoming for processing. It is shown that the meat yield depends on the month when veined rapa whelk was harvested. The highest yield was recorded for May and June; in July and August, a decrease in the yield of veined rapa whelk meat was observed, which resulted from the growth of egg cases on the mollusc shell. For the individuals, on which shells egg cases are absent, or have been removed, a unified standard of meat yield for the entire course of harvesting season should be adopted. The meat yield for the individuals, which shells have not been cleaned of egg cases, is recommended to be regulated separately. A relation between meat yield and shell length has not been found. Statistical analysis of the data obtained on the yield of veined rapa whelk meat has shown their adherence to the law of Gaussian distribution.
