Twig extract of the apple mangrove affects the activities of trypsin, chymotrypsin and lipase in postlarval black tiger shrimp Penaeus monodon at varying feeding frequencies

Abstract
This study aimed to determine the effect of the twig extract of the apple mangrove Sonneratia caseolaris on the activities of trypsin, chymotrypsin and lipase in the postlarval black tiger shrimp Penaeus monodon. Incorporating twig extracts of the apple mangrove S. caseolaris increased the activity of trypsin in juvenile P. monodon when fed at three to four times daily. When fed twice daily, trypsin activity was at the same level as that in shrimp fed the control diet (without medication). The extract resulted in the enhanced chymotrypsin activity starting when shrimps were fed medicated diet twice daily until four times daily. Lipase activity was not at all affected by the apple mangrove extract. These findings demonstrated that the twig apple mangrove extract could be used as a prophylactic/therapeutant an
