Effect of Enriched Conventional and Aminoacid Supplemented Feed on Length Weight Relationship of Freshwater Fish Oreochromis mossambicus [Peters]

Abstract

The present investigation was conducted to understand the length weight relationship of Oreochromis mossambicus for a period of sixty days. Enrichment of the conventional feed, containing rice bran and groundnut oil cake in equal proportions, with black gram and roots of winter cherry reduced the palatability. Aminoacids are known to act as good feeding stimulants. A screening of the different aminoacids for stimulant effect showed that the aminoacid leucine had the maximum influence on the feeding of Oreochromis mossambicus. Leucine was added to the enriched conventional feed at 0.1% level and the fishes were fed for sixty days to study to study the effect of black gram and roots of winter cherry on the length to weight relationship in Oreochromis mossambicus. Regarding length-weight relationship, for the experimental fish the slope was slightly higher indicating that these fish were heavier for their length when compared to the control fish.
