Abstract
Dynamics of biological indices such as relative condition factor, Gastrosomatic index (GaSI) and Hepatosomalic index (HSI) as well as food spectrum of Tilapia niloiiciis was monitored for a period of one year in fishes procured from Nadia and, North and South 24 Parganas districts of West Bengal. A significant variation (P < 0.01) was observed in GaSI and HSI values among males and females. The GaSI was found to be positively correlated with feeding intensity and HSI. Blue green algae, green algae and decayed organic matter constituted the major components of food items in different months exhibiting wide variations.
