Description The study was conducted to evaluate the efcacy of biofoc meal incorporated diets on
growth performance and physiological responses in Penaeus vannamei. The feeding trial
was conducted using two control diets and four experimental diets, having biofoc meal
at various incorporation levels, namely control diet (commercial diet), BFT0 (biofoc
meal control, biofoc meal at 0%) BFT10 (biofoc meal at 10%), BFT20 (biofoc meal
at 20%), BFT30 (biofoc meal at 30%), and BFT40 (biofoc meal at 40%). Healthy post
larvae of P. vannamei (0.03±0.00 g) were stocked (50 shrimp per tank) in a glass tank
and fed with the experimental diets at 10% of animal body weight, four times a day, for
a duration of 60 days. Among the diferent treatments, signifcantly higher fnal body
weight (1.30±0.06 g), weight gain (1.27±0.06 g), specifc growth rate (6.21±0.01%/
day), and survival rate (62±0.20%) were recorded in BFT30 diet. In contrast, shrimp
reared using control diet exhibited lower specifc growth rate (5.53±0.02%/day) and
survival (48±0.14%) compared to other treatment groups. At the end of the experiment,
serum protein (1.6±0.02 g/dl), prophenoloxidase (16.35±2.98 U/mg protein), and peroxidase (0.2±0.03 U/ml) were found to be signifcantly higher in BFT30 diet-fed group.
Similarly, the digestive enzyme activities of amylase (4.75±0.87 U/mg protein) and lipase
(118±5.10 U/mg protein) of BFT30 reared shrimp were found to be signifcantly higher.
In addition, the histological observation of the shrimp revealed the larger proportion of
mature cells with intracellular digestion (B) and absorption (R) in BFT30 group. Overall,
the study revealed that biofoc meal incorporation at 30% in shrimp diet would potentially
improves the growth performance and physiological responses of shrimp.
