A team of scientists from Fisheries and Oceans Canada (DFO) is conducting probiotic-type research to see if salmon have bacteria or bacterial bio-markers in their gut or mucus that makes them more resistant to sea lice. “Broodstock samples are being analyzed at Laval University. If results show that some salmon families have fewer sea lice counts and contained certain species of bacteria, we will then try applying a beneficial probiotic — perhaps in feed — to fish that don’t naturally have that resistance.”
