BioMar’s new feed diet said to eliminate cataracts in cleaner fish
Lumpfish with severe cataracts will have difficulty in identifying and consuming nutrients, including salmon lice
BioMar claims to have solved the challenges associated with diet-related cataracts in lumpfish with the launch of a new diet that will make a significant contribution to improving fish welfare and their lice-grazing efficiency.
Cataracts is the clouding of the lens of the eye which reduces vision and in serious cases will lead to blindness. Lumpfish are visual lice grazers, and any impairment of their vision caused by sub-optimal nutrition will clearly reduce their health, welfare and performance. For lumpfish to be used effectively in controlling salmon lice biologically the cleaner fish must be healthy and alert.
