Abstract

On the example of zebrafish Danio rerio, a new hydrodynamic installation “circular tank with limnozone” was tested to determine one of the indicators of the motivational component of rheoreaction in fish: the ratio of rheoreaction types. In contrast to the fish previously used in this setup, here the fish are given the opportunity to exhibit a rheoreaction of four, but not three types. A comparative analysis of rheoreaction assessment methods using three installations: “fishway”, “circular tank” and “circular tank with limnozone” was carried out. It is shown that the provision of the opportunity to exhibit an optional type of rheoreaction not only quantitatively, but also qualitatively changes the ratio of zebrafish rheoreaction types. The scope of the considered methods is determined.

评价鱼流变学动机成分的实验方法的比较（流变学类型的比例）

摘要

在斑马鱼Danio rerio的示例中，测试了一种新型水动力装置“带有limnozone的圆形水箱”，以确定鱼中流变的动力成分之一：流变类型的比率。与以前在此设置中使用的鱼相反，这里的鱼有机会表现出四种而不是三种类型的流变反应。比较了使用“鱼道”，“圆形罐”和“带limnozone的圆形罐”这三种装置的流变反应评估方法。结果表明，提供机会不仅可以定量显示变色反应类型，而且可以定性地改变斑马鱼变色反应类型的比率。确定所考虑方法的范围。
