Zmiinyi Island is the unique natural complex in the North-Western Black Sea. Its coastal waters are notable for their significant biodiversity, which had formed the basis for General Zoological Protected Area of national significance establishing in the area in 1998. The objective of this work is the studies of ichthyofauna biodiversity dynamics in the coastal waters of the Zmiinyi Island in 2003-2010 and revealing of the factors influencing the biodiversity. Ichthyological studies had been carried out in accordance with the national methodology using stake nets in 2003-2010. Altogether 500 stake-net catches had been studies. Visual underwater observations with the help of lightweight diving outfit had also been used. Studying the biodiversity of ichthyofauna we used three indices of communities' species composition: Margalef's species richness, Shannon's total diversity index and Pielou's evenness index. Results of ichthyological observations had been discussed.
