Description
Summary:On the basis of study the variability of some morphological and ecological (structure and otolite indices, seasonal dynamics of number and migration behavior) and biological (size, age and sex composition) characteristics of anchovy, wintering at the south-western coastal waters of Crimea (region Sevastopol – Balaklava) from November 2009 to March 2010 its intraspecific heterogeneity was observed. According the general structure and otolit index two statistical different (P<0.05) forms were indicated. Peculiarities of seasonal dynamics of number and migration behavior of these forms afford ground for to identify preliminary them as the representatives of Black Sea population and north-western coastal population. The dynamics of winter catches of anchovy were studied; the intraspecific composition and age structure of catches were considered.
