EU - EU-funded scientists have discovered that temperatures greater than 16ฐC can cause skeletal deformities in young salmon.
The researchers reared 400 juvenile salmon in water at a temperature of 10&deg;C and a further 400 at a temperature of 16&deg;C. Salmon farmers often use warmer water to increase fish growth rates, and the two tanks with the two temperatures were observed over a period of time to document any ensuing differences as a result of temperature.
Indeed, the study showed that bone and cartilage production was disrupted when temperatures were elevated. This resulted in an increased rate of deformities for the 16&deg;C group. This group of fish grew faster, but more than a quarter (28 per cent) was found to show some signs of skeletal deformity (compared to eight per cent of the fish in the 10&deg;C group).
