David Suzuki helps develop insect-based fish food
Long a vocal critic of B.C.’s conventional fish-farming industry, environmentalist David Suzuki has helped create a new product being tested as feed for farmed salmon.
Suzuki and Brad Marchant, CEO of the Vancouver-based start-up company Enterra, coined the idea of using maggots fed on food waste to create a sustainable source of protein while fly fishing in Yukon.
“For years we’ve been fighting salmon aquaculture, not because we are against aquaculture, but we felt that [conventional] aquaculture was the wrong way to do it,” Suzuki told The Vancouver Sun. “First of all, the salmon are grown in open nets, so you are using the ocean as a sewer. Closed containment is the way it has to go.”
Suzuki said he would oppose using the feed in open-net salmon aquaculture.
“I would not like that at all,” said Suzuki. “I think it should be used, with vision, in hard containers, but I think that [technology] is coming.”
“I wouldn’t be happy, but I guess it’s better than fish meal,” he said.
Recent advances in closed containment fish farming have begun to address some of the effects of salmon farms on wild salmon, predators and the marine environment, but feed remains problematic.
