Abstract/ Executive Summary:

Feeding metabolism in an Indian major carp, Catla catla fingerlings of 10.8+0.56g was investigated in a flow-through water recirculating system. The metabolic energy loss in resting metabolism and feeding metabolism were determined by the indirect method of oxygen consumption followed by multiplication by suitable oxycalorific coefficient. This was done in four metabolic chambers of a respirometer system. Ten fish fingerlings of mean total weight of 109.5, 110.4 and 112.8g/chambers respectively each in two experimental runs of three treatments a, b and c were used. The mean resting metabolic rate during unfed condition showed no significant variation in different treatments. The fish in three treatments a, b and c fed on diets containing 28, 33 and 38% crude protein had significantly different (p<0.05) post-fed SDA magnitude of 497.7, 638.7 and 735.5 mg chamber/day having an equivalent energy loss of 12.68, 14.68 and 15.86 KJ respectively. The SDA co-efficient in three treatments a, b and c were 14.95, 19.00 and 22.36% respectively whereas, respiratory energy- 'R' as % of mean total ingested energy in three treatments were 26.93, 31.17 and 34.74% respectively showing a significant increase (p<0.05) with increase of protein.

Commodity: Carp fish

Objectives:

To investigate the feeding metabolism- SDA in an Indian major carp, Catla catla fed on different protein diets.

Methodology:

Healthy fingerlings of Indian major carp, Catla catla (10-12 g from a single stock was collected in August 1996 from local fish farm. Acclimation of the fingerlings was made for 15 days in large plastic pool with continuous aeration at 28 + 1 °C.The fingerlings were given prophylectic treatment with NaCl (3%) dip for 10 minutes and 0.5mg/L methylene blue bath for 24 hours. Faecal matter produced by fingerlings were removed everyday morning and evening. The pool water was partly (about 40%) replaced with fresh aerated water every morning. The fingerlings were not fed on first two days of acclimation. From the third day they were given pelleted diet containing fish meal, mustard oil cake, wheat flour and bran etc. having 30% dietary protein at the rate of 1% as maintenance ration. Normal dark- light period was maintained throughout the study period. The experiment was conducted in metabolism chamber in a flow through water recirculatory system in laboratory of Fisheries Technology Department. Measurement of respiration rates in unfed, fed and post-fed condition were done in system of metabolism chambers. Three experimental diets A, B and C containing 28, 33 and 38% crude protein levels respectively were prepared by using fish meal, mustard oil cake, duck weed, rice bran and wheat bran.The diets prepared as pellets were sun dried for 1 day followed by oven drying at 70°C for over night. The diets were fed at a known ration to three treatment groups of fish in metabolism chambers. Each of three treatments had two replicates each having ten fishes of 10.8+0.56 g fish in metabolism chambers. The metabolism chambers were marked as MD M2, r and M3 where the chamber "r" was used as reference and had no fish in it. A constant water flow- rate of 30 L/h through the flow meter was maintained in all metabolism chambers during direct monitoring of oxygen consumption by an oxygen probe kept in cuvette. After the first day in unfed condition for acclimation in the chambers, the fish fingerlings were subjected to measure resting metabolic rate for the following two unfed days over 24 hours period. The 24 hours measurement of the oxygen consumption (directly measured by oxygen probe of oxygen meter in the cuvette) in each three group of fish were measured.After 3 days, the fishes in metabolism chambers a, b and c were given known amount of diets having either 18, 33 or 38% crude protein. Feeding of fish started at 9.00 am and continued up to 4.00 pm. The pellets which were left uneaten and entered into faecal column collected, dried. The uneaten weight were subtracted from the amount offered to fish and the value was treated as the amount of diet ingested. Alternate hourly feeding of fish continued according to their response during feeding period. Twenty four hours hourly monitoring of oxygen consumption as mg O₂/kg/h of the post-fed fish group of fish in each metabolism chambers was recorded for alternate 13 days as days 3, 5, 7, 9, 11, 13. 15, 17, 19, 21, 23,25 and 27 for each replicates.The proximate composition of the diets, fish and faeces were analysed according to standard procedure. Statistical analysis of the study was done by analysis of variance (ANOVA) to compare treatment means using the statistical package
