"Our research indicates that cod would benefit significantly from a lower-temperature environment during first-feeding," says Dr Baeverfjord. The same findings apply to salmon. Researchers believe that maintaining low water temperature during the early development phases is the most important preventive measure fish farmers can implement for both species.
However, in other areas cod and salmon show differences. "Cod must not be subjected to too strong a current in the tank. We recommend slowing down the current to prevent spinal column fractures. This is the second-most important measure for avoiding malformations in cod. For salmon, improper feed is the number two cause of abnormalities."
"Our conclusion is that both cod and salmon should be given a more peaceful start to life than they get now," states Dr Baeverfjord, advising producers not to stress their fish too much during the fry stage
