The nutritional value of whole, dehulled, extruded, dehulled–extruded and micronized feed peas, and extruded canola meal, included at a 30% concentration as ingredients in diets for juvenile blue shrimp was assessed. Pea meals replaced a portion of soybean meal and wheat (1:3 parts) on an isonitrogenous and isoenergetic basis, and similarly extruded canola meal replaced a portion of soybean meal, fish meal and wheat (1:2:3 parts) of a control diet. After 28 days, the shrimp almost tripled their weight on the experimental diets. Performance was unaffected by dehulling, except for a slight increase in feed consumption and lower protein efficiency ratio (PER). Extrusion cooking had no effect on growth and survival but significantly improved feed conversion and PER. The micronized pea diet produced the highest feed intake and growth rate. Response to the diet containing extruded canola meal was similar to that …
