The body temperatures of rainbow trout, Oncorhynchus mykiss were monitored from June through August 2018 in three trout farms from Bistrița-Năsăud County (Romania). The body emperature was measured from 3 different regions of the body: head, trunk (epaxial and hypaxial muscle region) and caudal peduncle. Body temperatures were compared to the asins water temperature. The lowest water temperature in the basins was recorded in May and June, in Șoimul de Jos farm, and the highest temperature in Fiad farm. In July, trâmba farm, recorded the highest water temperature, and in August, Fiad farm. In all farms studied, the body temperature of the trout was higher than that of the basins water temperature regardless of the studied region. The highest differences between the basins water and body temperature in farms were found in the caudal peduncle and epaxial uscle regions, due to their role in locomotor mechanism. This is due to the high growth density, the feeding and the intensification of metabolism, with energy release, as ell as a much higher level of stress than that encountered in the natural environment.
