Feeding intensity and diet composition of Hilsa
Shad (Tenualosa ilisha) from Northern Bay of Bengal were
studied between June 2010 and March 2011. The stomach
contents of 320 fishes were analyzed from the northern part
of the Bay of Bengal to understand the food items of this
species. The major constituents of food are organic debris
(26.06 ± 5.19 % SD), diatoms (31.22 ± 11.97 % SD),
other algae (12.41 ± 2.62 % SD), and crustaceans (3.50 ±
1.28 % SD). The most abundant species of diatoms were
Coscinodiscus, Pleurosigma, Bacillaria, Nitzschia, Bid dulphia, Diatoma and Asterionella. The stomach of Hilsa
was found to be almost empty during June to October while
it was almost full during November to March. Significant
positive correlation among feeding intensity, chlorophyll-A
concentration and salinity of the ambient water indicated
that feeding in T. ilisha is influenced by a number of fac tors. Strong positive correlation between percentage
occurrence of diatoms and intensity of feeding indicated
their preference for diatom–food.
