Bruken av rensefisk fra et dyrevelferds- og bærekraftsperspektiv : en litteraturstudie

Sea lice cause significant challenges for the aquaculture industry due to welfare problems, loss in biomass, delice treatments and interactions between escaped farmed salmon and wild stock. Cleaner fish will naturally eat parasites and have become an important biological resource for preventing and...
