Research project on the impact of sea lice on salmon fisheries
Plymouth University and the Universidad de Chile are leading a new research project to investigate the issue of sea lice infestation.
The two year project will bring experts together to study the effect that the lice have upon the salmon’s skin and gut defences, and the way it hampers physiological processes and their ability to withstand other infections.
Funded by a £385,000 grant from the Biotechnology and Biological Sciences Research Council, and the Chilean government (CONICYT), the project will identify the factors involved in determining salmon susceptibility to lice in order to develop effective measures to address this increasingly global issue.
Current strategies to control sea lice have included the administration of a number of licensed and antiparasitic drugs, but the parasites have become increasingly resistant, leaving salmon farms vulnerable to infestation. It also threatens related industries such as traditional fisheries due to the potential transfer of infection from cultured fish to those in the wild.
Plymouth academics will work with colleagues at the Universities of Aberdeen, Glasgow, Heriot Watt, and the Universidad de Chile and key industrial partners including BioMar, Lallemand and Veterquimica, to examine what impact the sea lice have upon the skin mucus which forms the salmon's first line of defence, and how it responds to that infestation.
“Understanding both lice and salmon responses to infection will lead to the development of novel feed ingredients that will benefit the industry,” said Dr John Tinsley from BioMar.
The researchers will then look at the efficacy of dietary supplements on the fish’s immune system, the microbes on its skin and its ability to develop resistance to sea lice infestation – as well as investigating the impact of dietary supplements upon the lice. These findings will be validated on a commercial farming scale to help inform suitable future treatment strategies for aquaculture to improve the salmon’s resistance to infestation.
