| Description |
The length weight relationship of Dasyatis imbricatus (schneider) was calculated separately for males and females. The results show that exponent is greater than 3 for females suggest ing that growth is not strictly isometric. Analysis of gut contents reveal the bottom feeding nature of this ray with crustacean forms constiluting 64.8% followed by polychaetes with 33.5 of the feed. The size at first maturity is determined by relating the percentage of liver weight in body weight to the average body weight and also to the length of the body. |
