Abstract

Biomass of the coastal fish fauna of Gokçeada Island was seasonally investigated at different stations between August 1995 and June 1996. Fish species were collected by means of trammel net and gill net from 6 stations around the island. Biomasses of the 59 species were calculated (260.647 g). Seasonal productivity index (P’) among the stations was determined by means of Shannon-Weaver Index. Productivity index was the highest in the spring at the stations I (P’; 3.995) and III (P’: 3.673).
