That modified within the s when fishermen outfitted their nets with tires that bounced trawls over reefs, opening the fishery to devastatingly environment-friendly trawlers. While the study has completed one of the most comprehensive assessments of the prevalence and factors associated with ling cod blueness so far, outstanding mysteries remain about why the fish have their special colouring, Galloway said.
Other research reviewed for the study examining different types of blue fish suggest the colour may provide UV protection in shallower waters, he added. Tests from fish showed that blue-fleshed ling cod had a lower concentration of fatty acids, said Galloway, noting higher fatty acid counts — derived from food sources — generally indicate good health or fitness in fish. So, a dietary difference in shallow waters might trigger a blue colour, compared with fish that spend most of their time in deeper habitat, he said.
Research on other fish indicates poor diet can trigger an increase in blue bile pigments, he said. Ideally, experiments in a laboratory setting could explore if nutritional stress would turn a ling cod blue, Galloway said. Join our Newsletter. Home Islander Why are some ling cod bright blue?
