Studies on energy budget in relation to various dietary conditions were made in an air breathing fish, Channa striatus (BL.). The feeds used were-poultry gut content + goat liver (Group A), blood clot or meal (B), Poultary droppings + Rice bran (C) and goat gut content (Group D). Food efficiency (%) ranged from 11.50 -48.4%. Daily individual growth increment (g/fish/day) ranged from 0.117 (Group A) to 0.501 (Group D). The details have been discussed in this paper.
In the present work an attempt has been made to study energy value of metabolism (respiration or oxygen consumption) in a fresh water teleostean fish, Channa striatus (Bloch) at water temperature 29.5±1.00C. The energy value of total metabolism (R) ranged from 723.1-10390.3 Joule/day/fish within the weight range 9.3 to 103.0 gram fish. The percentage of total energy of food (C) used in the metabolism (R) ranged from 36.0-40.7% with a clear trend of decrease in R value with increasing body weight. The details have been discussed in this paper.
