چکیده
  Neogobius caspius is an endemic species of the Caspian Sea which plays an important role in food chain as a predatory fish. The main aim of this study was to investigate selected feeding characteristics of Neogobius caspius in the south west coasts of the Caspian Sea. Monthly sampling was carried out using a bottom trawler at three stations (Astara, Anzali and Chabuksar) in three depths (0-5, 5-10 and 10-15m) on a monthly basis from October 2004 to September 2005. Relative gut length (RLG) was less than one suggesting that this species is carnivorous. RLG was significantly lower in older fish but gut length was longer (P < 0.05). I ntensity of fullness was below the favorite degree (IF
