dc.description.abstractThe roughskin sculpin (<em>Trachidermus fasciatus</em>) belongs to the family Cottidae and is a small carnivorous catadromous fish distributed along the coasts of China, Korea, and Japan. The effects of heat stress on roughskin sculpin have yet to be systematically performed. This study aimed to explore the effects of chronic heat stress on the roughskin sculpin. The survival rate, gill histopathological changes, and heat stress protein gene expression patterns of roughskin sculpin were analyzed after different temperature stresses of 19 ℃, 22 ℃, 25 ℃, 28 ℃, and 31 ℃ for 0, 3, 6, 9, and 12 days. The results revealed that roughskin sculpin could not survive at 33 ℃. Chronic heat stress can cause severe damage to gill tissue, reducing the gills' respiratory efficiency. Moreover, the expressions of <em>hspb1, hspb7, and hspb11</em> changed significantly after heat stress. In the 31 ℃ treatment group, as stress time increased, <em>hspb1, hspb7, and hspb11</em> expression initially increased and then decreased. This study’s results provide a reference for the study of heat stress physiology of roughskin sculpin as well as a new idea and method for evaluating and breeding heat stress traits of roughskin sculpin.
