“…From previous research, studying digestive enzymes with other Macrobrachium prawns, it is observed that M. tenellum certainly differ from other prawns. For example, trypsin, chymotrypsin, and total alkaline proteolytic activity were higher in Macrobrachium carcinus juveniles examined by Silva et al (2020) than in present M. tenellum cultured prawns, but lipase and α amylase were comparable. A different amount of protein in a more digestible kind might have contributed to such differences in addition to the fact that M. carcinus is a more carnivorous prawn (Farias Lima, da Silva García, & Carvalho da Silva, 2014), so it seems to be more efficient in the production of proteolytic enzymes.…”

Macrobrachium tenellum is an omnivorous freshwater prawn living in rivers near the coast and in coastal lagoons with potential to be cultured. It is distributed in rivers, estuaries, and coastal lagoons, and in each of those habitats, it has access to food items with different features and nutritional content. In this research, it has been tested if this variety of food availability has an immediate effect on their digestive enzymatic activity once animals are brought to laboratory and fed with different meals.Wild prawns were captured in a river and coastal lagoon, and after acclimation, they were fed with three different experimental diets. Total alkaline protease, trypsin, chymotrypsin, lipase, and α amylase were measured from prawns fed experimental diets at 15 and 30 days. There were significant differences in the enzymatic activity of prawns depending on their original habitat and diet. However, the proportion in which these enzymes are expressed in the prawns from different treatments remains proportional to what was observed in wild specimens, as reported in previous research. We consider that

“…This also seems to be the case of M. carcinus . Silva et al (2020) suggest that even the juvenile stages of this species may need high protein level in the diet because of its lower amylase to protease ratio.…”
