Environmental impact and molecular regulation of the osmoregulatory gill during parr-smolt transformation in Atlantic salmon

High quality salmon smolts are critical for aquaculture, enhancement programmes and wild populations. Intensification of aquaculture smolt production and changes in natural habitats can cause degradation of environmental conditions, which may severely red uce smolt quality. The gill is critical i...

Molecular typing of Aeromonas salmonicida- the cause of serous disease in farmed marine fish

Most if not all marine-fish currently held in captivity in Norway are susceptible to infection with Aeromonas salmonicida. Current expansion in farming of new marine species will almost certainly lead to increased isolations of A. salmonicida. Losses can be high and the bacterium is often difficu...

Improving metamorphic success and juvenile quality in Atlantic halibut and white grouper through dietary supplementation of iodine

Abstract Iodine is an essential nutrient and part of the thyroid hormones thyroxine and triiodothyronine. The hormones initiate the metamorphosis in vertebrates and iodine deficiency may therefore result in incomplete metamorphosis. Fish in general cover their iodine requirement from the diet as ...
