Scientists and fish farmers are working on new ways to control the pests, which So far it has been an uphill struggle that is a threat to a way of life in countries where salmon farming is a part of the culture.
“Our work has to be quicker than the evolution of the lice,” said Jake Elliott, vice president of Cooke Aquaculture in Blacks Harbour, New Brunswick.

That technology was developed in Norway and has been used there and in Scotland.
Cooke keeps a brood stock of fish in the hopes of breeding them for desirable traits such as disease resistance.
Farmed salmon was worth nearly billion in 2015, according to the Food and Agriculture Organisation of the United Nations.
The only hope is to develop new methods to control the spread of lice, which are present in the wild, but thrive in the tightly packed ocean pens for fish farming, said Shawn Robinson, a scientist with the Canadian Department of Fisheries and Oceans.
“There are not enough tools right now to allow the farmer to really effectively deal with it,” said Robinson.
Research about farming salmon along with mussels, which researchers have found will eat larval sea lice, is underway.
Underwater drones inhabit the other end of the technological spectrum, zapping lice with lasers to kill them.
