Welcome to AquaDocs!

AquaDocs is the joint open access repository of the UNESCO/IOC InternationaI Oceanographic Data and Information Exchange (IODE) and the International Association of Aquatic and Marine Science Libraries and Information Centers (IAMSLIC) with support from the FAO Aquatic Sciences and Fisheries Abstracts. It is a thematic repository covering the natural marine, coastal, estuarine /brackish and fresh water environments and includes all aspects of the science, technology, management and conservation of these environments, their organisms and resources, and the economic, sociological and legal aspects.

  • International Coastal Atlas Network Newsletter Vol. 9 No. 2

    Sherin, Andrew (International Coastal Atlas NewtorkHalifax, Nova Scotia, Canada, 2020-12)
    This issue the ICAN newsletter focuses again on the UN Sustainable Development Goals with articles on the Global Partnership for Sustainable Development Data and other SDG relevant articles. It has a highlighted article on the Maryland Coastal Atlas and an update on the Ocean Information Hub.
  • 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.
