    • Abstract


      In a factorial design of experiment, effects of feeding frequency on food utilization were studied inChanna 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 ofC. 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.
