The present study evaluated the potential of squid by-product hydrolysate as fishmeal replacement in the plant-based diet of juvenile black tiger shrimp Penaeus monodon Fabricius 1798. Five experimental plant protein-based diets were formulated containing squid by-product hydrolysate to replace fishmeal at 0 25 50 75 and 100 . These experimental diets were fed to triplicate groups of P. monodon for 8 weeks. Results revealed that 25 fishmeal replacement with squid by-product hydrolysate resulted in growth enhancement attributable to increased feed intake and gut lactic acid bacteria proliferation. The shrimp fed with 100 replacement level exhibited a similar growth response with the control group. Protein retention was not affected by the fishmeal replacement levels but lipid retention was found higher in all treatments with squid by-product hydrolysate than the control. Digestive protease activity decreased with increasing levels of hydrolysate while -amylase and lipase activities were not affected. Hepatopancreas histology showed that B-cells dominated the control group while R-cells proliferated with increasing inclusion of dietary squid by-product hydrolysate. These results collectively indicate that fishmeal could be totally replaced with squid by-product hydrolysate and 25 fishmeal replacement could promote the growth of juvenile P. monodon.

Abstract

The present study evaluated the potential of squid by-product hydrolysate as fishmeal replacement in the plant-based diet of juvenile black tiger shrimp Penaeus monodon Fabricius 1798. Five experimental plant protein-based diets were formulated containing squid by-product hydrolysate to replace fishmeal at 0 25 50 75 and 100 . These experimental diets were fed to triplicate groups of P. monodon for 8 weeks. Results revealed that 25 fishmeal replacement with squid by-product hydrolysate resulted in growth enhancement attributable to increased feed intake and gut lactic acid bacteria proliferation. The shrimp fed with 100 replacement level exhibited a similar growth response with the control group. Protein retention was not affected by the fishmeal replacement levels but lipid retention was found higher in all treatments with squid by-product hydrolysate than the control. Digestive protease activity decreased with increasing levels of hydrolysate while -amylase and lipase activities were not affected. Hepatopancreas histology showed that B-cells dominated the control group while R-cells proliferated with increasing inclusion of dietary squid by-product hydrolysate. These results collectively indicate that fishmeal could be totally replaced with squid by-product hydrolysate and 25 fishmeal replacement could promote the growth of juvenile P. monodon.
