Genetic variation for growth rate, feed conversion efficiency, and disease resistance exists within a farmed population of rainbow trout
Abstract The objective of this study was to test that additive genetic (co)variation for survival, growth rate, feed conversion efficiency, and resistance to viral haemorrhagic septicaemia (VHS)Expand

Selective breeding provides an approach to increase resistance of rainbow trout (Onchorhynchus mykiss) to the diseases, enteric redmouth disease, rainbow trout fry syndrome, and viral haemorrhagic
Abstract In this study, we reasoned that if we challenged rainbow trout with the causative agents of enteric redmouth disease (ERM), rainbow trout fry syndrome (RTFS), and viral haemorrhagicExpand

Effects of stocking density and sustained aerobic exercise on growth, energetics and welfare of rainbow trout
Abstract Two stocking densities, “low” (L, between ~ 19 and ~ 25 kg m − 3 ) and “high” (H, between ~ 75 and ~ 100 kg m − 3 ) were compared for effects on specific growth rate (SGR), feed conversion,Expand

The influence of aerial exposure upon respiratory and osmotic properties of haemolymph from two intertidal mussels, Mytilus edulis L. and Modiolus modiolus L.
Abstract pH and PO2, in Mytilus edulis L. and Modiolus modiolus L. decrease, while PCO2 and the concentrations of Ca2+ and Cl− increase during air exposure. The increase in the concentration of Ca2+Expand

Aspects of respiratory physiology and energetics in rainbow trout (Oncorhynchus mykiss) families with different size-at-age and condition factor
Abstract This study investigated whether two farmed rainbow trout families that differed in two production traits, size at age (SA) and condition factor (CF), also differed in aspects of theirExpand

Moderate exercise of rainbow trout induces only minor differences in fatty acid profile, texture, white muscle fibres and proximate chemical composition of fillets
Abstract These experiments studied how moderate water velocities (0.9 body length second − 1 (bl s − 1 )) may influence different quality characteristics of rainbow trout when compared to fish keptExpand

Replacement of fish meal by potato protein concentrate in diets for rainbow trout, Oncorhynchus mykiss (Walbaum): growth, feed utilization and body composition
Five experimental diets (PPC1, PPC2, PPC3, PPC4 and PPC5) containing about 465 g kg−1 crude protein were formulated to contain graded levels of potato protein concentrate (PPC) (a by-product ofExpand

Effect of dietary levels of fat, α-tocopherol and astaxanthin on colour and lipid oxidation during storage of frozen rainbow trout (Oncorhynchus mykiss) and during chill storage of smoked trout
Abstract Female rainbow trout (Oncorhynchus mykiss) with an initial weight of 0.8–0.9 kg were raised in two experiments including a total of 2550 fish divided into 17 groups. The fish were raised forExpand

The effects of stocking density and low level sustained exercise on the energetic efficiency of rainbow trout (Oncorhynchus mykiss) reared at 19 °C
Abstract A 9 week growth trial was performed at two rearing densities; low (~ 25 kg m − 3 ) and high (~ 100 kg m − 3 ), in combination with either static water or a water current corresponding to 0.9Expand

Effects of rearing density and water current on the respiratory physiology and haematology in rainbow trout, Oncorhynchus mykiss at high temperature
Abstract Rearing fish at high densities is considered stressful. For many species this leads to poor feed conversion, decreased feed intake and reduced growth, possibly caused by a change in energyExpand
