摘要: In coho salmon Oncorhynchus kisutch, no significant differences in critical thermal maximum (c. 26·9° C, CTmax ) were observed among size-matched wild-type, domesticated, growth hormone (GH)-transgenic fish fed to satiation, and GH-transgenic on a ration-restricted diet. Instead, satiation had significantly higher heart rate Arrhenius breakpoint temperature (mean ± s.e. = 17·3 0·1° TAB ). These results provide insight into effects of modified tolerance salmonids, can be used assess the potential ecological consequences fishes should they enter natural environments with temperatures near their limits.
