... field detection. Among teleost fish, growing evidence suggests that crystals of the mineral magnetite provide the physical basis of the magnetic sense. In this study, juvenile Chinook salmon ( Oncorhynchus tshawytscha ) were exposed to a brief but strong magnetic pulse capable of altering the magnetic...

... 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 ranging in M b from 2.7 to 16.8 kg while they roamed freely...

... of this study is to examine the relationship between the critical swimming velocity ( U crit ) and the functional haemoglobin concentration ([Hb]) of the blood in adult chinook salmon. Functional [Hb] was reduced by increasing MetHb levels through intraperitoneal administration of a mass-dependent volume...

...H. Thorarensen; P. E. Gallaugher; A. K. Kiessling; A. P. Farrell ABSTRACT Blood flow in the intestinal artery ( q IA), the rate of oxygen consumption and a number of haematological variables were measured in chinook salmon, Oncorhynchus tshawytscha , while they swam up to the critical swimming...

...Peter J. Rombough; Brenda M. Moroz ABSTRACT Measurements were made of the surface areas of the yolk sac, the fins, the head and trunk, the gill filaments and the gill lamellae of chinook salmon ( Oncorhyn-chus tshawytscha Walbaum) weighing between 0.045 g (3.7 days posthatch) and 13.4g (180 days...
