Marine Ecological Journal| Zusammenfassung: | Comparative analyzes of current status of ichthyopankton in coastal waters of southwestern Crimea (Sevastopol region) based on literature date and ichthyoplankton samples collected in 2002-2008. The dynamics of abundance, survive, species diversity of ichthyoplankton are shown. The increase of average abundance of eggs as well as larvae and recovery species numbering up to standard of sixties of XX century is significant (Indexes of Species Similarity – 0.9). The positive long-term changes in species diversity of ichthyopankton and the lognormal distribution the species by value, testify the stable condition of ichthyoplankton in investigated period. However, the replacement dominate sold commercially migrant species of fish larvae in favor of little value resident species, testifies lowering of the importance of the coastal waters of Sevastopol as region of generation of commercially species of fishes. |
