Abstract:

A 40-day experiment was conducted to study the effect of de-oiled oil palm kernel meal based biofloc system on growth performance and digestive enzyme activity of Litopenaeus vannamei. Juveniles of L. vannamei with an average weight of (0.82±0.02 g) were stocked in tanks with a water volume of 150 L at a stocking density of 300 PL m-3. Highest weight gain percentage (519.05±9.52), protein efficiency ratio (1.78±0.02) and survival rate (88.67±0.88) were observed in oil palm kernel meal based biofloc treatment. Lowest FCR value (1.61±0.02) has been recorded in biofloc treatment. Although the digestive enzymes had not shown any significant difference, a slight increase in the protease and amylase activities have been observed in biofloc treatment. So the present study suggests that non-conventional carbon source – de-oiled oil palm kernel meal can be utilized for the development of biofloc.
