Saw this on the news today and it looks promising. Using Wrasse to control sea lice on salmon farms has to be a more sustainable solution that using chemicals or am I being naive ? It wont be the first time that big business has promoted an eco friendly approach to mask the real picture. Some of the wrasse also looked rather small so I hope the salmon don't prefer them to pellets! Laughing

Anyway, have a look here and see what you think.

Alan it's a PR stunt by Marine Harvest et al .The industry is under pressure to clean up their act due to the millions and millions of sea lice destroying the salmon and sea trout smolts migrating to sea notwithstanding the use of toxins to control their numbers. On land Closed Containment for the industry is the way forward - no highly toxic chemicals deposited into the sea, eradication of sea lice and most importantly no escapees mixing their genes with the native wild salmon.

Now here's a question - why would a cleaner fish eat sea lice when they have tons and tons of high protein feeder pellets available??????

Cheers

I agree, Doug. Closed containment is the only completely safe option, with the added advantage that they can micro-manage the environment for optimum growth etc Smile
