Effects of biodensity on the growth, stress physiology, and welfare of Arctic charr in freshwater
Category : Aquaculture
Biodensity is a major factor affecting the production and welfare of farmed fishes. During a 91 day study, Artic charr were held at 5 biodensities and examined key growth, stress physiology, and welfare parameters. Growth rates were lower in charr reared at the highest biodensities while feed efficiency was negatively affected at both the highest and lowest biodensities. The results support an optimal biodensity range for charr culture between 60 and 90 kg/m3 to optimize production and welfare.
