Glandless Cottonseed Meal Replaces Fishmeal In Shrimp Diet Research

摘要

Dietary protein in aquafeed, which accounts for the majority of content and expense, is typically comprised of fishmeal and soybean meal. Due to the high cost of fishmeal and long-term sustainability issues, a number of alternate protein sources havebeen examined over the years as complete or partial replacements for fishmeal. Cottonseed meal has a number of benefits as a potential fishmeal replacement. It is a safe, heavy metal-free plant protein source that is high in protein, less expensive thanfishmeal and generally less expensive than soybean meal. However, normal glanded cottonseed meal contains gossypol, a compound that is toxic to aquatic animals, including shrimp.
