Pending changes to the law means there would no longer be a requirement for new fish farms to undergo environmental assessments and, therefore, no more opportunity for public input.

By John Werring, Senior Science and Policy Advisor

Canada's Department of Fisheries and Oceans is working with the aquaculture industry to expand fish farms on the West and East coasts and the Great Lakes. In March 2010, the David Suzuki Foundation and 400 people from all walks of life attended a public meeting held by DFO in Campbell River to consult West Coast residents about the plans. This was the public's chance to offer input. A government official at the meeting brushed off concerns I raised, but now it appears my warnings were correct.

Squamish Streamkeepers Society is a small group of volunteers who made a big difference in the marine recovery of Howe Sound. They noticed that creosote-covered wood pilings at Squamish Terminal were killing herring roe and they did something about it. When herring eggs are directly exposed to creosote, 90 per cent of them die. The polycyclic aromatic hydrocarbons in the coal tar product penetrate the fish embryos, halting egg development after a few days. The volunteers wrapped a plastic material used for weed control around 200 pilings with amazing results: the return of schools of healthy herring after decades of absence, followed by a myriad of marine mammals in search of meals.

Every March, thousands of eastern Pacific grey whales repeatedly dive, surface and blow plumes of water vapor during their migration north along North America's west coast. After wintering in tropical waters off the Baja peninsula, most travel over 10,000 kilometers to summer feeding grounds in the Bering Sea. But some "summer residents" end their migration right here along British Columbia's coast.

Snow dusts the mountaintops, the skies and water are a uniform grey and the creek draining into the dive site is icy cold. Family barbecues and laughing children that crammed the seaside parks only a few months ago are now long gone. There's no one here but us divers.
