The influence of body mass (M(b)) on the physiology of large, adult fish is poorly understood, in part because of the logistical difficulties of studying large individuals. For the first time, this study quantified the influence of M(b) on the resting heart rate (f(H)), blood properties and organ masses of adults of a large-growing fish species, the Chinook salmon (Oncorhynchus tshawytscha). Surgically implanted biologgers measured f(H) and acceleration activity in sexually mature, male fish… CONTINUE READING
