Rendered meals workable feed ingredients for Pacific white shrimp
Rendered meals, or feeds with ingredients made from animal byproducts, meet many important criteria and have excellent prospects for aquaculture feeds.
New feed practices can reduce environmental impacts of shrimp farming, including the replacement of fishmeal and fish oil with sustainable lipid sources.
