摘要

摘要实验记录了长期恒定光照（100和1000勒克斯照度）对虹鳟幼鱼（Oncorhynchus mykiss）行为及其血液中甲状腺激素和皮质醇水平的长期影响（53天）。在 100 勒克斯照度下，虹鳟鱼向上游和下游移动的次数相同；也就是说，它们的行为是停留在当前栖息地。照度为 1000 勒克斯时，鱼类更多地向上游移动，即它们的行为是离开当前栖息地。实验光照制度对鱼类血液中的甲状腺激素和皮质醇水平没有影响。

Effect of Illumination on the Movement of Rainbow Trout Oncorhynchus (Parasalmo) mykiss (Salmonidae) Juveniles in Water Flow and the Level of Thyroid Hormones and Cortisol in Their Blood

Abstract

Long-term influence (53 days) of long-term constant illumination (100 and 1000 lux illuminance) on the behavior of rainbow trout (Oncorhynchus mykiss) juveniles and the level of thyroid hormones and cortisol in their blood has been experimentally recorded. At 100 lux illuminance, the fish moved equally upstream and downstream; i.e., their behavior was to stay in the current habitat. At 1000 lux illuminance, the fish more often moved upstream; i.e., their behavior was to leave the current habitat. The experimental illumination regimes did not affect the thyroid hormones and cortisol levels in the fish blood.

期刊介绍： Journal of Ichthyology is an international peer-reviewed journal published in collaboration with the Russian Academy of Sciences. It covers original studies in fish taxonomy, evolution, molecular biology, morphology, species diversity, zoological geography, genetics, physiology, ecology, behavior, reproduction, embryology, invasions, and protection. Some problems of applied ichthyology are also covered. The journal welcomes manuscripts from all countries in the English or Russian language.
