此實驗在於以一種蛋白酵素添加至基本餌料，然後餵食幼石斑（14天大）以評估其生長與存活。在28天之餵食後，基本餌料組與蛋白酵素添加餌料組之生長與存活率並無顯著之差異，而活豐年蝦餌料餵食幼石斑在存活率（66.6％）或體重（60.2 mg）與皆有最佳之表現。餌料中之蛋白酵素失去活性可能導致幼石斑在28天基本餌料與蛋白酵素添加餌料之餵食試驗間無顯著生長與存活差異。 A bacterial protease was supplemented to a basal diet and fed to the 14 day-old grouper (Epinephelus sp.) larvae for the evaluation of growth and survival. After a 28-day feeding, survivals or body weight of the grouper larvae were no significant difference between the basal diet and protease supplemented diet. Live Artemia nauplii diet fed to the larvae gave the best performance either on final percentage survival (66.6%) or body weight (60.2 mg). The inactivity of protease enzyme in the diet may cause the no significant difference for the growth and survival between protease supplemented diet and basal diet in the 28 day feeding trial.
