Aquaculture vs. lobster fishing on Canada's east coast

Although figures vary, it's estimated that at least half of the fish and shrimp available to consumers around the world comes from fish farms, or “aquaculture”.

Biologist Alexandra Morton is a well-known activist arguing against commercial-scale fish farms on the west coast of Canada.  Now on a tour of the east coast, she has joined lobster fishermen and tourist operators who are opposing fish farms there.

Unlike the west coast where the pens are in deeper water, she says the large salmon pens on the east coast tend to be in shallower bays which are not flushed to the same extent by tides and currents.  She claims this creates a number of serious issues ranging from low-oxygen near “dead zones” under and around the pens. to chemicals which weaken the shells of lobsters and shellfish, and anti-biotics which create bacteria resistance. 

While such open-sea pens are often stocked with Atlantic salmon, fish farming can also involve other species like cod, shrimp, carp, and steelhead trout among others.

Sitting is bad for your health

Canadians young and old spend a lot of time sitting. Many studies have found that sitting for long periods are bad for your health and is even associated with early death. But a large analysis of all the research confirms it.

But how much sitting are we talking about? What kinds of diseases do we risk? What happens to our bodies when we sit? Are we still at risk even if we exercise every day? And how do we change our behaviour to reduce the risks associated with sitting too much?

Travis Saunders is a PhD candidate at the Children’s Hospital of Eastern Ontario Research Institute.  He studies the health impact of sedentary behaviour and explained it to RCI’s Lynn Desjardins.
