大多数鱼类是生活在水中的变温动物,因此温度是影响鱼类生长发育重要的非生物因素。在温度发生变化时,鱼类不会进行适应性基因变异,而是会通过忍受、抵制或偏好等热调控行为来降低环境压力。通过总结近年来鱼类热调控行为的研究成果,比较不同种类、同种异龄、同种同龄鱼在温度变化中生境选择、游泳、摄食、生殖洄游等行为差异,分析造成该差异可能的内在机制,以及温度突变中热调控蛋白和表观遗传学对鱼类生存影响的研究进展,阐述鱼类的热调控行为是其根据外界条件和自身需求做出的一个复杂的综合性行为,其目的是获得最大化的热调控优势。为了更深入解读全球气候突变对鱼类生存的影响,需要对鱼类热调控行为及调控机理进行更进一步的研究。
Most fish are warm-blooded animals that live in water, so temperature is an important abiotic factor that affects fish growth and development. When temperature changes, fish do not undergo adaptive genetic variation, but rather reduce environmental stress through thermoregulatory behaviors such as endurance, resistance or preference. By summarizing the research findings on the thermal regulation of fish in recent years, the differences in habitat selection, swimming, feeding and reproductive migration among different species, same-age and same-age fish under different temperatures were analyzed. The possible internal causes of this difference were analyzed Mechanism and thermo-regulated protein and epigenetics on the survival of fish in the sudden change of temperature. It is a complex and comprehensive behavior that fish’s thermal regulation behavior is based on external conditions and their own needs. Is to get the maximum thermal regulation advantage. In order to further understand the impact of global climate change on fish survival, we need to further study the heat regulation and control mechanism of fish.
