Abstract

Non-random mating plays a key role in speciation and impacts the individual life history. Body size is known to be one of the most important traits on which the mate choice is based. Various patterns of body size preference are known in fish, but they have been studied in a limited number of species. Although the climbing perch (Anabas testudineus) is widespread and well known, a few reports of its spawning are published. Moreover, its breeding has only been described in captivity and in most cases it has been artificially induced with hormonal agents. This paper describes the main features of natural spawning of the climbing perch in aquarium compared to induced spawning. A positive size-assortative mating has been revealed. The mating system of Anabas has been shown to be flexible, presumably ranging from monogamy to polygamy. The results are discussed in the context of the general issue of the adequacy of fish behaviour research methods.

攀鲈 Anabas testudineus 中的配偶选择和大小分类交配（Actinopteri：Anabantidae）

摘要

非随机交配在物种形成中起着关键作用，并影响着个体的生活史。众所周知，体型是择偶所依据的最重要特征之一。已知鱼类有多种体型偏好模式，但仅在有限数量的物种中进行了研究。尽管攀鲈（Anabas testudineus）分布广泛且广为人知，但已发表了一些关于其产卵的报告。此外，它的繁殖只在圈养中进行过描述，在大多数情况下，它是用激素人工诱导的。本文描述了与诱导产卵相比，攀鲈在水族馆中自然产卵的主要特征。已经揭示了正大小选型交配。Anabas的交配系统已被证明是灵活的，大概从一夫一妻制到一夫多妻制。结果在鱼类行为研究方法的充分性这一普遍问题的背景下进行了讨论。
