卤虫和水蚤是众所周知的最适合养殖幼虫的活体饲料。适宜的大小、易消化、高营养价值是鱼早期选择活体饲料的主要标准。一些必需的脂肪酸在该物种中含量较低，浓缩是改善脂肪酸的另一种方法。因此，它可以作为满足仔鱼营养需要的适当饲料。大多数是利用油脂等高脂肪来源进行浓缩，油源浓缩剂量为2~3ml/L，对仔鱼的营养价值有积极影响，提高成活率，促进生长。近年来，活饲料的利用面临着可持续发展的现实问题，如纯菌株的可获得性、无病原菌、环境条件的高度维护等。这可能是小规模行业确保活体饲料质量和可持续性的主要限制。为了解决这一问题，人们进行了大量的研究。本文讨论了对幼体养殖中最常用的几种活体饲料，如卤虫、水母、水蚤和幼虫的各种补充方法。工业分析也成为额外的信息，如在更高的浓缩剂量下蛋白质含量的增加。
Artemia and daphnia are well known as the most suitable live feeds for larviculture. The appropriate size, easy digest, and high nutritional value are the main criteria to choose as a live feed in early stage of fish. Some of essential fatty acids are low in this species and the enrichment is one of other ways to improve the fatty acids. Thus, it can be the appropriate feed to fulfill the nutritional requirement of larvae. Mostly, enrichment have been done using the source of high content of lipid such as oil enrichment, the dose 2-3 ml/l of oil source enrichment could give a positive impact to the nutritional value of larva, increase the survival rate, and boost the growth performance. Recently, the utilities of live feeds facing the reality of sustainable issues such as the availability of pure strain, pathogen free, and the high maintenance of environmental condition. It could be the major limit for small-scale industry to ensure the quality and sustainability of live feeds. Many studies have been carried out to magnificent this problems. This paper discuss about the various enrichments for the most used live feeds in larviculture, such as Artemia, Moina, Daphnia, and Infusoria. The proximate analysis also become the additional information such as the increasing of protein contents in higher dose of enrichment.
