Influence of gelatinous zooplankton on fish stocks in the Black Sea: analysis of biological time-series

Abstract

Scientific information about the Black Sea ecosystem with respect to jelly plankton – fisheries interactions is reviewed. Long time-series of the main components of pelagic community: fishes, invertebrates, discussed trends, and relationships between them are analysed. The amount of information and results from the analyses will be used to formulate hypotheses about the linkages between gelatinous plankton and the other pelagic populations and the effects on fish stocks. These data will be used as a background study for the following stages in the Eurogel project: experimental work, data analyses and modelling.
