Studies on total corpuscular and plasma volume in relation to body weight have been made in an air breathing siluroid fish,Clarias batrachus (Linn) by Dye dilution technique using Evan blue (T-1824) for plasma volume and haematocrit method for corpuscular volume. Plasma and corpuscular volume per gram body weight decrease from lower to higher weight groups but become constant at 70 gram animals. The total plasma and corpuscular volume increase from lower to higher weight groups. They show the following relationship:

Body weight Vs. Plasma volume logY =log 0.0130+0.9227logW

Body weight Vs. Corpuscular voi logY = logO. 0309+0.6000 logW

Plasmavol. Vs. Corpuscularvol. logY=log0.5192+0.6479logW

The coefficient of correlation between body weight Vs. Plasma volume, body weight Vs. corpuscular volume and between plasma volume Vs. corpuscular volume have been computed in be 0.9989, 0.9980 and 0.994 respectively. This shows high degree of correlation between all the foregoing parameters and sed

 In the present work an attempt has been made to study the effect of five different types of supplementary feeds on weight gain (SGR), food efficiency and individual growth increment (g/fish/day) in a fresh water air breathing teleost, Channa marulius (Ham.). The experiment was conducted for 60 days in cemented tank (having soil at the bottom). The average daily individual growth increment (g/fish) were 0.502 with rice bran+ground nut oil cake (GNOC), 0.505 with Maize bran + GNOC, 0.510 with fish meal + GNOC; 0.513 with spoiled boiled (SB) egg and 0.517 with SB Egg+Maize bran as compared to control (0.105). The merits and demerits of different feeds have been discussed in this fish.

In the present work an attempt has been made to study some aspects of bioenergetic modelling with special reference to the assessment of maintenance energy expenditure and energy value in growth materials in a teleostean fish, Channa gachua (Ham.). Over all maintenance energy expenditure in this fish ranged from 62.3% or 1522.5 Joules (J) in 16.3g fish to a value of 64% or 17094.4J (in 104.0g fish). The energy value utilized for growth/production (P) ranged from 37.7% or 917.5J (in 16.3g fish) to a value of 36.0% or 9615.6J (in 104.0g fish) of the total energy available in food (C). The details have been discussed in this paper.
