The application of protease in aquaculture: Prospects for enhancing the aquafeed industry

引用

Animal Nutrition 2024年第1期16卷 105-121页

作者： Shiyou Chen Sahya Maulu Jie Wang Xiaoze Xie Xiaofang Liang Hao Wang Junjun Wang Min Xue National Aquafeed Safety Assessment center Institute of Feed Research Chinese Academy of Agricultural Sciences State Key Laboratory of Animal Nutrition College of Animal Science and Technology China Agricultural University School of Biological and Marine sciences Faculty of Science and Engineering University of Plymouth Centre for innovative Approach Zambia (CIAZ)

Low-fishmeal and protein-saving diets are two prominent nutritional strategies utilized to address challenges related to the scarcity and sustainability of protein sources in aquaculture. However, these diets have been associated with adverse effects on the growth performance, feed utilization, and disease resistance of aquatic animals. To mitigate these challenges, exogenous protease has been applied to enhance the quality of diets with lower protein contents or fishmeal alternatives, thereby improving the bioavailability of nutritional ingredients. Additionally, protease preparations were also used to enzymatically hydrolyze fishmeal alternatives, thus enhancing their nutritional utilization. The present review aims to consolidate recent research progress on the use of protease in aquaculture and conclude the benefits and limitations of its application, thereby providing a comprehensive understanding of the subject and identifying opportunities for future research.
