The performances of hybrid grouper, epinephelus Fuscoguttatus × e. Lanceolatus fed with defatted soybean mealbased feeds with supplementation of phytase
Fish meal is the primary protein ingredient in fish feed and this material is expensive and non-renewable. However, the use of plant protein in marine fish feed such as soybean meal products are limited due to anti-nutritional factor that hindered fish performances. Therefore, hybrid grouper, a cros...
