Marine Ecological Journal| Резюме: | 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 wors-ened: reduction of age class number, decrease of average fishery length and weight, average fishery age were observed. Principles of biologically optimum fishery regulation have been working out. |
