WebbAfter 7 weeks of rearing, density ranged from 6.5 to 16.3 kg/m2 (14.7–36.6 g/L). Fish reared at the lowest density had significantly higher mean weight and length at the end of the trial. Growth over the 7-week experiment was modeled as a function of time, and growth rate was inversely proportional to density. WebbThe aim of this study was to determine the effects of feed restriction and rearing density on the migratory behaviour of Atlantic salmon smolts in the lower part of the flow-controlled river Umeälven in northern Sweden. Twenty acoustic receivers were deployed along the river section to cover all possible migration routes.

WebbThe hypotheses are if rearing density is increased, then hatching success will also be improved, while having no effect on embryo development; if the salt concentration is increased to 20 parts per thousand (ppt), then the rate of development will also be increased; if temperature is increased to 32°C, then the rate of development will also be … WebbOne-year-old rainbow trout Oncorhynchus mykiss were reared for 8 weeks at a density of either 56 or 267 g fish/L (based on the volume of net-pens), equivalent to density indexes … how to check neco result with your phone
