Evaluation of food selection of Catla catla (Hamilton) fingerling by determining electivity index grown in earthen ponds in Bangladesh

One month old fry of a planktivorous Indian major carp species, catla, Catla catla (Hamilton) was reared upto fingerling stage in earthen ponds in order to determine the food preference and selection using lvlev's Electivity Index under two different treatments. Except Chlorophyceae, it showed...

Description
Summary:One month old fry of a planktivorous Indian major carp species, catla, Catla catla (Hamilton) was reared upto fingerling stage in earthen ponds in order to determine the food preference and selection using lvlev's Electivity Index under two different treatments. Except Chlorophyceae, it showed positive selection to Cyanophyceae, Euglenophyceae, Rodophyceae, Crustacea and Rotifera. However, Catla, during its fry-fingerling stage exerted strong preference for zooplankton and almost neutral response to phytoplankton in both conditions.
