Abstract
The present study was carried out to determine the Length-weight relationship and feeding biology of Chanda nama (Hamilton, 1822) belongs to Ambassidae was collected during the period between January 2017 and March 2017 from Vettar river near Nagore Cauvery river basin of Tamil Nadu. In this study based on 75 specimens consisting ranging 5.0-8.5 cm in total length and 1.20-5.66 gm in total weight. The length-weight relationship of Chanda nama shows negative allometric growth. The r2 values show the linear relationship between the length and weight of the specimens. The food items in the stomach of Chanda nama suggest that they are carnivorous. The gut content analysis was revealed that among the six different food categories only two items namely algae and crustacean appendages were abundant throughout the study period. The present study is useful for an efficient and meaningful exploitation and regulation of the Chanda nama fishery in Vettar river, due to important edible food fish around Nagore Cauvery river basin area.
