We review knowledge on applications of sustained aerobic swimming as a tool to promote productivity and welfare of farmed fish species. There has been extensive interest in whether providing active species with a current to swim against can promote growth. The results are not conclusive but the studies have varied in species, life stage, swimming speed applied, feeding regime, stocking density and other factors. Therefore, much remains to be understood about mechanisms underlying findings of ‘swimming‐enhanced growth’, in particular to demonstrate that swimming can improve feed conversion ratio and dietary protein retention under true aquaculture conditions. There has also been research into whether swimming can alleviate chronic stress, once again on a range of species and life stages. The evidence is mixed but swimming does improve recovery from acute stresses such as handling or confinement. Research into issues such as whether swimming can improve immune function and promote cognitive function is still at an early stage and should be encouraged. There is promising evidence that swimming can inhibit precocious sexual maturation in some species, so studies should be broadened to other species where precocious maturation is a problem. Swimming performance is a heritable trait and may prove a useful selection tool, especially if it is related to overall robustness. More research is required to better understand the advantages that swimming may provide to the fish farmer, in terms of production, mitigation and selection.

集约化鱼类养殖中的有氧游泳:生产,减缓和选择的应用

我们回顾了关于持续有氧游泳的应用知识,以此作为提高养殖鱼类生产力和福利的工具。对于向活动物种提供逆流游泳是否能促进生长具有广泛的兴趣。结果尚无定论,但研究种类,寿命,游泳速度,喂养方式,放养密度和其他因素各不相同。因此,关于“游泳增强生长”发现基础的机制还有很多待理解,特别是证明在真实的水产养殖条件下,游泳可以提高饲料转化率和膳食蛋白质保留率。还研究了游泳是否可以减轻慢性压力,这再次针对一系列物种和生命阶段。证据不一,但是游泳确实可以提高从急性压力(如处理或分娩)中恢复的能力。诸如游泳能否改善免疫功能和促进认知功能等问题的研究仍处于早期阶段,应予以鼓励。有前途的证据表明,游泳可以抑制某些物种的性早熟,因此研究应扩大到性早熟成问题的其他物种。游泳成绩是可遗传的特征,并且可能证明是一种有用的选择工具,尤其是在与整体健壮性有关的情况下。需要进行更多的研究以更好地了解游泳在生产,减缓和选择方面可能给养鱼户带来的好处。诸如游泳能否改善免疫功能和促进认知功能等问题的研究仍处于早期阶段,应予以鼓励。有前途的证据表明,游泳可以抑制某些物种的性早熟,因此研究应扩大到性早熟成问题的其他物种。游泳成绩是可遗传的特征,并且可能证明是一种有用的选择工具,尤其是在与整体健壮性有关的情况下。需要进行更多的研究以更好地了解游泳在生产,减缓和选择方面可能给养鱼户带来的好处。诸如游泳能否改善免疫功能和促进认知功能等问题的研究仍处于早期阶段,应予以鼓励。有前途的证据表明,游泳可以抑制某些物种的性早熟,因此研究应扩大到性早熟成问题的其他物种。游泳成绩是可遗传的特征,可能被证明是一种有用的选择工具,尤其是在与整体健壮性有关的情况下。需要进行更多的研究以更好地了解游泳在生产,减缓和选择方面可能给养鱼户带来的好处。因此研究应扩大到早熟是一个问题的其他物种。游泳成绩是可遗传的特征,并且可能证明是一种有用的选择工具,尤其是在与整体健壮性有关的情况下。需要进行更多的研究以更好地了解游泳在生产,减缓和选择方面可能给养鱼户带来的好处。因此研究应扩大到早熟是一个问题的其他物种。游泳成绩是可遗传的特征,并且可能证明是一种有用的选择工具,尤其是在与整体健壮性有关的情况下。需要进行更多的研究以更好地了解游泳在生产,减缓和选择方面可能给养鱼户带来的好处。
