Because of its high nutritional value, palatability and increased digestibility, fishy meal is widely used as an animal protein source in the aquafeed industry. However, the resource shortages and rising prices seriously restrict the use of fish meal (FM) in aquaculture. In this light, much efforts have been conducted to seek the sustainable supplies of protein sources to substitute FM. Due to their relatively low protein content and palatability, the presence of anti‐nutritional factors (ANFs) and unbalanced amino acid profiles, the plant protein sources have been limited in aquafeed, whereas the animal protein sources can replace FM in aquafeed due to their high protein content, total digestible dry matter and lack of ANFs. The fermentation process was recognized for its role in improving the nutritional quality of animal and plant protein sources. The protein sources can be treated with appropriate microorganisms to preserve its nutrients and finally incorporated into aquafeed, which would reduce feed costs and environmental pollution. Fermented meals showed better nutrient efficiency and could improve the nutritional value of aquafeed. This review was intended to present more updated information about the application of fermented ingredients in aquafeed industry. Based on the data collected, this review will contribute to further research into the production of fermented feed as a functional feed for sustainable aquaculture.

发酵策略在可持续水产养殖水产饲料中的应用

由于鱼粉具有很高的营养价值，适口性和更高的消化率，因此被广泛用作水产饲料工业中的动物蛋白来源。但是，资源短缺和价格上涨严重限制了水产养殖中鱼粉的使用。有鉴于此，已经进行了许多努力以寻求蛋白质源的可持续供应来替代FM。由于它们的蛋白质含量和适口性相对较低，抗营养因子（ANF）的存在和氨基酸分布不平衡，因此水产饲料中的植物蛋白来源受到限制，而动物蛋白来源由于其高含量而可以替代水产饲料中的FM。蛋白质含量，总可消化干物质和缺乏ANFs。发酵过程因其在改善动植物蛋白质来源的营养质量中的作用而得到公认。可以用适当的微生物处理蛋白质源，以保留其营养，最后将其掺入水产饲料中，这将降低饲料成本和环境污染。发酵粉具有更好的营养效率，可以提高水产饲料的营养价值。这篇综述旨在提供有关发酵成分在水产饲料行业中应用的更多更新信息。根据收集到的数据，这次审查将有助于进一步研究发酵饲料作为可持续水产养殖的功能性饲料的生产。这将减少饲料成本和环境污染。发酵粉具有更好的营养效率，可以提高水产饲料的营养价值。这篇综述旨在提供有关发酵成分在水产饲料行业中应用的更多更新信息。根据收集到的数据，这次审查将有助于进一步研究发酵饲料作为可持续水产养殖的功能性饲料的生产。这将减少饲料成本和环境污染。发酵粉具有更好的营养效率，可以提高水产饲料的营养价值。这篇综述旨在提供有关发酵成分在水产饲料行业中应用的更多更新信息。根据收集到的数据，这次审查将有助于进一步研究发酵饲料作为可持续水产养殖的功能性饲料的生产。
