What is the primary source of protein in fish meals?

• A. Plant by-products from cereals
• B. Caught or waste from processing fish for human consumption
• C. Rendered animal by-products
• D. Algal biomass

Answer: (B)

Fish meal gets its protein from fish-derived material, typically whole fish or by-products generated during processing for human consumption. This material is cooked, rendered, and dried to produce a stable, high-protein meal that is easy to blend into aquaculture feeds. That makes the primary source of protein in fish meals the catch and processing waste of fish. The other options don’t define fish meal: plant by-products from cereals are plant-based proteins, not fish-derived; rendered animal by-products refer to non-fish origin materials like land-animal meals; algal biomass is an alternative protein source but not the traditional, defining input for fish meal.
