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.
“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.Salmon have a lousy problem, and the race to solve it is spanning the globe.A surge of parasitic sea lice is disrupting salmon farms around the world.Then, farmers in Canada identified the lice as a problem around 1994, said Jonathan Carr, executive director of research and environment with the Atlantic Salmon Federation.
Feeding fish a pesticide with the active ingredient of emamectin benzoate became the tool of choice to control lice, Carr said.
But around 2009, the lice appeared to become resistant to the pesticide, and they have spread globally since.
