The length frequency distribution of the whole sample exhibited unimodal distribution ; one peak observed at length 90 mm indicates that catches were exclusively based mainly on one year-class individuals. S.

elongata had not been caught during November.

Length-Weight relationship was found to be : W = 2.

6 x 10-6 L 3.

285.

Growth rate was estimated to reach the length 100-109 in 1.

1 year.

Feeding activity values ranged from 50 to 85 %, while the minimum feeding intensity ratio was 0.

4 point/fish and the maximum 3.

2 point / fish.
