Biochar Conditioned Feeds Related to Enzyme Activity in an Economically Important Carp Labeo Bata of Tripura, India

Abstract

Labeo bata  is considered an important fish due to its preference as delicious protein food to the peoples. For  promoting fast growth of this species under commercial farm culture knowledge of digestive enzyme activities related to effective feed is important. As efficient  supplementary diet biochar conditioned feed is used. Quality of supplementary diet is identified with proximate composition of  biochar feed showing occurrence of rich nutrients in the feeds.

Amylase and trypsin activities showing significant difference of value between the  experiments done with biochar conditioned feeds with a comparison to other.  Enzyme activities during starvation period have significant variations from that of a period after 8 hrs of feeding to Labeo bata. Regression analysis   between the metabolic faecal nitrogen (g N/100 g dried biochar feed) and biochar feed nitrogen (%) exhibiting a significant correlation (R²= 0.9088).
