Title Studies on food and feeding habits of catfish
Tachysurus tenuispinis (Day)
 
Creator Mojumder, P
Dan, S S
 
Subject Catfish
 
Description It is observed that 37% of the food of Tachysurus teniiispinis, consists of
crabs, prawns, Squilla sp and orustacesn remains; 26% polychaetes, 6.5%
molluscs, 6.3% teleosts, 4.2% ophiuroids and the rest miscellaneous food items.
T. tenuispinis is, therefore, a carrtivorous bottom feeder. As a single food item,
polychaetes are most preferred.
The fTuctuations in the intensity of feeding (points) and the volume of
stomach contents (ml) in different months generally showed similar trends both
in the small (less than 27.5 cm total length) and large (more than 27.5 cm total
length) catfish. The relative importance of various food items during different
months shows that feeding is selective.
