Abstract: 

In order to evaluate the feeding habits of tiger-toothed croaker (Otolithes rubber) 239 specimens were collected during December to March, 2003 in coastal areas of Chabahar, Iran. Stomach contents were examined by using of the numerical method. The abundance and frequency percents and type of preys, along with the percentage of emptiness of stomach, and prey dominant were evaluated during different months and in different groups based on upon length, sex and maturity. Result showed that in tiger-toothed croaker prey fish was the dominant and specific food item. There were monthly changes in feeding intensity and the feeding was weak. The percentage of emptiness stomach in March and December were highest and lowest, respectively. The empty stomach index (CV) indicated that tiger toothed croaker belong to the fish group with medium food intake. Shrimp was the main food in immature fish and with increasing in length and maturity of fish; shrimps were replaced with fish prey as the main food.
