Interactions of feeding frequency and density on food utilization in air-breathing murrel, Channa striatus

Abstract

In a factorial design of experiment, effects of feeding frequency on food utilization were studied in Channa striatus. Feeding frequency is positively related, whereas density is negatively related to the tested energetics components; absorption efficiency remains independent of both feeding frequency and density. Based on the minimum water requirement, a fish pond with an average depth of 1·5 m and an area of 1 ha could be stocked with 1·15 million fry of C. striatus, of size 3 g. There is a significant interaction between feeding frequency and density suggesting that adverse effects of density could be compensated by increasing the frequency of feeding.
