ABSTRACT:
A total of 4200 fish of large scale tongue sole Cynoglossus arel were collected from the Iraqi marine waters at the shallow tip of the Arabian Gulf during the period extended from September 2014 to July 2015 by using trawl nets. The relationship between the total length and weight was calculated according to the following equation y = 0.0064x2.8521. Regression value (b) which calculated for all species was not significantly differ from the value of 3. L8 and K were estimated to be 38cm and 0.23, respectively. Relative ages of fish species were ranged between 1-7 years. Species value of total mortality rate (Z) was estimated to be 6.61, the value M was 1.24, thus F became 5.36. Water average annual temperature measured as 21.25 °C. Food analysis was performed according to the values of the index relative importance (IRI). Mollusca scored the highest percentage (41.3%). Food composition dominance was followed by shrimp (25 (%1 . , fish (19.2 %), crab (7.6) coming in third rank and finally digested matter which represented only (6.8 %) .
