| Abstract: | Maize gluten (a byproduct from the starch industry) was used at four different levels (5, 10, 15 and 20% w/w) replacing the
fish meal, a component of supplementary diet, under a semi-intensive culture system. The impact of different diets on the
physico-chemical parameters of water, growth and flesh quality of catla, Catla catla; rohu, Labeo rohita; and mrigal, Cirrhina mrigala was studied. Growth in terms of body weight gain was highest when fed a diet having 5% maize gluten (replacing fish meal
at 25% level) for all the fish species. However, incorporation of maize gluten at higher levels led to decline in growth,
since maize gluten is deficient in essential amino acids like methionine, lysine and threonine, etc. The flesh quality in
terms of total protein, total lipid, total sugar, moisture and total ash was also determined at the termination of the experiment
to see whether there was any significant variation with the incorporation of maize gluten or not. |
