Long-term dynamics of fishery and length-age structure of the Black Sea anchovy (Engraulis encrasicolus ponticus Aleks) catches in Ukraine

Summary:On the basis of long-term (1999 -- 2012) research data both inter- and intra-annual patterns of Ukrainian fishery of the Black Sea anchovy (Engraulis encrasicolus ponticus Aleks), wintering off the south-west and southern coast of Crimea and length-age structure have been studied. Absolute values of annual catches and their inter-annual fluctuations have been considered. The tendency of consecutive increase of catches and while «quality composition» of catches worsened: reduction of age class number, decrease of average fishery length and weight, average fishery age were ob-served. Principles of biologically optimum fishery regulation have been working out.
