Abstract

Effects of food items (mosquito larva; pupa, ehironomous larva and chopped pieces of the fish Lepidocephalichthyes thermalis) on food utilization and surfacing activity of Channa Striatus fry were studied. Test individuals fed on live food organisms surfaced 94- 117% more frequent ly, consumed 23- 119% more ralions/day and, on an average, converted 33% more than those fed on pieces of Lepidocephalichthyes thermalis. Regardless of the quality of food, Channa striatus surfaced about 60 times/h before each meal and the frequency increased to 130 timesfh 3- 6 h after the meal was offered and returned to the prefeeding level 18- 21 h after the meal.
