Catfish (Siluriformes) are important species for aquaculture worldwide, with an annual production in 2018 of ca. 6 million t. This review focuses on reassessing larval development, first feeding, and early rearing practices of the most important farmed catfish species, along with some candidate species for aquaculture diversification: Pangasianodon hypophthalmus (Pangasiidae), Clarias gariepinus (Clariidae), Ictalurus punctatus (Ictaluridae), Pseudoplatystoma spp. (Pimelodidae), Heteropneustes fossilis (Heteropneustidae), Rhamdia quelen (Heptapteridae), Ompok bimaculatus (Siluridae), and Lophiosilurus alexandri (Pseudopimelodidade). These species are initially reared indoors from one day to two weeks and are then transferred to fertilised outdoor ponds where they either feed on natural zooplankton or compound feeds. With the exception of C. gariepinus, I. punctatus, R. quelen and P. hypophthalmus, consistent and reliable fry production is a bottleneck that limits the expansion of farming of other species, such as Pseudoplatystoma spp., H. fossilis, O. bimaculatus, and L. alexandri. Rearing systems (extensive, semi-extensive, intensive) and feeding protocols vary with species and geographical regions. Cannibalism and size heterogeneity are common, and these features create problems for larval and fry rearing of catfish species. Information about their nutritional requirements is required for the formulation of compound feeds that can guarantee high survival and good growth of catfish fries. However, such knowledge for most species is scarce, although some data are available for I. punctatus. Further genomic resources might allow fine-tuning rearing success. This review describes some successes in this field, and also highlights gaps in knowledge to guide future research that can promote the development of catfish aquaculture.

早期阶段相关鲶鱼种类（鲶形目）的发育、营养和饲养实践

鲶鱼（鲶形目）是全球水产养殖的重要物种，2018 年的年产量约为. 600万吨。这篇综述的重点是重新评估最重要的养殖鲶鱼物种的幼虫发育、首次投喂和早期饲养实践，以及水产养殖多样化的一些候选物种：Pangasianodon hypophthalmus (Pangasiidae)、Clarias gariepinus (Clariidae)、Ictalurus punctatus (Ictaluridae)、假扁桃体属 (Pimelodidae)、Heteropneustes rocks (Heteropneustidae)、Rhamdia quelen (Heptapteridae)、Ompok bimaculatus (Siluridae) 和Lophiosilurus alexandri（假吡美洛狄）。这些物种最初在室内饲养一天到两周，然后转移到受精的室外池塘，在那里它们以天然浮游动物或复合饲料为食。除了C. gariepinus、I. punctatus、R. quelen和P. hypophthalmus之外，稳定可靠的鱼苗生产是限制其他物种养殖扩大的瓶颈，例如Pseudoplatystoma spp.、H . bimaculatus和L. alexandri. 饲养系统（粗养、半粗养、集约化）和饲养方案因物种和地理区域而异。同类相食和大小异质性很常见，这些特征给鲶鱼种类的幼体和鱼苗饲养带来了问题。配制复合饲料需要有关其营养需求的信息，以保证鲶鱼苗的高存活率和良好生长。然而，大多数物种的此类知识很少，尽管有一些关于I. punctatus的数据。进一步的基因组资源可能允许微调饲养成功。这篇综述描述了该领域的一些成功，并强调了知识差距，以指导可以促进鲶鱼水产养殖发展的未来研究。
