Abstract
In the current study, the intestinal content
of Catla catla fish was examined. The fish were gathered in
Uttarakhand's Tumaria Reservoir near Udham Singh Nagar. It was noted that the
crustaceans (Cladocerans and Copepods) made up the majority of the gut
contents, accounting for 31.00% by volume and 42.15% by occurrence. Rotifers
came in second in terms of dominance, accounting for 18.60% by volume and
15.20% by occurrence, followed by insects, which accounted for 13.00% by volume
and 10.20% by occurrence. Additionally, the group of green algae or
Chlorophyceae, made up 15.00 percent of the intestinal material by volume and
9.70 percent by occurrence. Diatoms, or Bacillariophyceae, were the next
significant component of the gut contents, accounting for 10.0% of the volume
and 7.30% of the occurrence, myxophyceae was 7 % by volume and 6.50 percent by
occurence. It was observed that catla is planktophagus and feeds primarily on
zooplankton. Studies on gastrosomatic index (GaSI) of Catla catla
revealed that the feeding intensity remained high during winter months and
reduced during summer months.
