Potential application of protein hydrolysate from shrimp by-products in aquaculture feed in Vietnam

Abstract

The study provides a comprehensive assessment of the potential of using hydrolyzed protein and shrimp protein hydrolysate (SPH) to partially replace fishmeal (FM) in aquafeed in Vietnam. Shrimp processing by-products, which are often discarded or used as low-value products, can be converted into a high-quality protein source through hydrolysis. SPH has been shown to help improve fish growth, feed efficiency, and survival rates thanks to its high digestibility, palatability, and bio-active peptides that are beneficial to animal health; It can therefore partially replace fishmeal, complement plant-based proteins, and be a domestically sourced, efficient and sustainable feed ingredient for aquaculture.
