Enzymatic activity in the shrimp Penaeus vannamei fed at different feeding frequencies

ABSTRACT Correct management of the feeding regime in shrimp aquaculture has been beneficial. Still, when looking for improvement in shrimp performance, the results have been contradictory, and the limits between better growth and independent growth as a function of the feeding regime are not clear....

In this study, trypsin and α-amylase activity, as well as an interpretation of the energy utilized for enzyme production, were evaluated in shrimp weighing 1 g.

Results indicated that the group fed once per day ingested 90% of the feed, whereas the other groups ingested 100%. The α-amylase was not consumed during the daytime in all groups, unlike trypsin. Total trypsin activity was not significantly different between feeding groups, but α-amylase was significantly different. Shrimp fed eight times had an elevated α-amylase activity level that was 2.6 times greater than those fed only once, and 0.8 and 0.5 times greater than those fed four and twice per day, respectively.
