Among ray-finned fishes that provide parental care, many spawn in constructed nests, ranging from bowls, burrows and ridges to nests made of algae or bubbles. Because a nest by definition is a construction that enhances the nest-builder's fitness by helping it meet the needs of the developing offspring, nest-building behaviour is naturally selected, as is a preference for spawning with mates that provide well-built nests. However, nest-building behaviour can also be sexually selected, when nest traits increase mating success, protect against sperm competition or nest take-overs by conspecifics. Here, we offer a systematic review, with examples of how competition for sites and location of fish nests relates to sexual selection. We examine direct and indirect benefits of mate choice linked to nest traits, and different types of nests, from a sexual selection perspective. Nest-related behaviours are often under both natural and sexual selection, and we disentangle examples where that is the case, with special attention to females. We highlight some taxa in which nest building is likely to be sexually selected, but lack of research has left them uninvestigated. Some of them are established aquarium species, making them particularly amenable for future research. Finally, we compare with arthropods, amphibians and birds. This article is part of the theme issue 'The evolutionary ecology of nests: a cross-taxon approach'.
在提供亲代照顾的硬骨鱼类中，许多鱼类在构造的巢穴中产卵，这些巢穴的形状范围从碗状、洞穴状和脊状到由藻类或气泡构成的巢穴。因为巢穴的定义是一种通过帮助巢筑者满足发育后代的需求来提高其适应性的结构，所以巢筑行为是自然选择的结果，同时，鱼类也会选择与提供良好巢穴的配偶进行繁殖。然而，当巢的特征增加了交配的成功率、保护免受同种竞争的精子竞争或巢穴侵占时，巢筑行为也可以受到性选择的影响。在这里，我们提供了一个系统的综述，通过例子展示了鱼类巢穴的位置和地点如何与性选择有关。我们从性选择的角度检查了与巢穴特征相关的配偶选择和间接利益，以及不同类型的巢穴。巢相关行为通常受到自然选择和性选择的影响，我们梳理了那些情况的例子，特别关注雌性。我们强调了一些可能受到性选择影响的筑巢类群，但由于缺乏研究，这些类群尚未得到调查。其中一些是已建立的水族馆物种，这使得它们特别适合未来的研究。最后，我们将其与节肢动物、两栖动物和鸟类进行了比较。本文是主题为“巢穴的进化生态学：跨类群方法”的一部分。
