... committee for animal experimentation. Rainbow trout ( Oncorhynchus mykiss Walbaum) were obtained from a local fish farm near the University of Joensuu (Finland). In the lab, fish(257.16±12.13 g, N =27) were reared in temperature-controlled 1000 litre stainless steel tanks with a continuous supply...

... and fast myotomal muscles were measured in the rainbow trout Oncorhynchus mykiss . These two muscle fibre types generated distinct low and high myoelectric frequency bands. The cat paw-shake is an activity that recruits mainly fast muscle. This study showed that the myoelectric signal from the medial...

...Collins Kamunde; Martin Grosell; Dave Higgs; Chris M. Wood SUMMARY Juvenile rainbow trout Oncorhynchus mykiss were exposed to diets with low (12.6 nmol g –1 ), normal (50.4 nmol g –1 ) or elevated (4437.5 nmol g –1 ) Cu concentrations in combination with either low (5.8 nmol l –1 ) or normal (48.5...

.... The effects of amino acids upon intestinal zinc uptake in freshwater rainbow trout ( Oncorhynchus mykiss ) were studied using an in vivo perfusion technique. The presence of histidine, cysteine and taurine had distinct modifying actions upon quantitative and qualitative zinc absorption, compared to perfusion...

...Svante Winberg; Øyvind Øverli; Olivier Lepage SUMMARY Juvenile rainbow trout Oncorhynchus mykiss were isolated in individual compartments in observation aquaria and allowed to acclimate for 1 week, during which they were fed commercial trout feed. Thereafter, the fish were tested for aggressive...

...S. Panserat; E. Plagnes-Juan; S. Kaushik SUMMARY Rainbow trout ( Oncorhynchus mykiss ) are known to use dietary carbohydrates poorly. One of the hypotheses to explain the poor utilisation of dietary glucose by these fish is a dysfunction in nutritional regulation of hepatic glucose metabolism...

...E. Rahaman-Noronha; M. J. O’Donnell; C. M. Pilley; P. A. Wright ABSTRACT This study examined ammonia excretion by embryos of the rainbow trout ( Oncorhynchus mykiss ). The distribution of ammonia in relation to the H + distribution and electrical potential was determined. The influence of the pH...

This study measured routine and maximum in situ cardiac performance in rainbow trout ( Oncorhynchus mykiss ) following acclimation to 15, 18 and 22 °C, under conditions of tonic (30 nmol l -1 ), intermediate (60 nmol l -1 ) and maximal (200 nmol l -1 ) adrenergic stimulation. Heart rate increased...
