ABSTRACT This study assessed the nutrient profiles of major grower shrimp feeds in Brazil used in semi-intensive farming of Penaeus vannamei and their impact on shrimp growth under optimal (15.8 ± 0.14 ppt), hypoosmotic (3.9 ± 0.57 ppt), and hyperosmotic (41.8 ± 0.62 ppt) salinities. Juvenile shrimp (0.85–1.60 g) were stocked at 50 animals/m2 in 40 outdoor tanks (1 m3) and fed across three consecutive trials lasting 63 to 86 days. Dietary nutrient composition varied widely, with crude protein ranging […]
