May 3, 2016 — Heather Goldstone, of NPR affiliates WGBH and WCAI, discusses bycatch reduction in fisheries on a recent episode of “Living Lab.” Her guests were veteran gear designer Ron Smolowitz of the Coonamessett Farm Foundation, who has worked with the southern New England scallop industry; Steve Eayrs, a research scientist at Gulf of Maine Research Institute, who has worked with groundfishermen in Maine; and Tim Werner, a senior scientist with the New England Aquarium, who put acoustic pingers on gill nets to warn away dolphins. An excerpt from the segment is reproduced below:
It’s the holy grail of commercial fishing: catch just the right amount of just the right size of just the right species, without damage to the physical environment. It’s a tall order, and few fisheries are there yet.
Leaving aside the issue of straight up over-fishing, the Food and Agriculture Organization of the United Nations estimates that, each year, fishermen around the world accidentally catch more than seven million tons of marine life – everything from whales and turtles, to sea cucumbers – that they weren’t even after. Such by-catch, as it’s known, is essentially collateral damage.
And fishing has other environmental impacts. In some parts of the ocean, the scars left by trawls dragged across the sea floor can be seen for years.
But, it doesn’t have to be that way. Over the past decade or so, a lot of effort has gone into designing fishing gear and related equipment that allows fishermen to catch more of what they do want, and less of what they don’t, while also minimizing damage to the environment. For example:
- Veteran gear designer Ron Smolowitz and the Coonamessett Farm Foundation have worked with the southern New England scallop industry over the past several years to develop a trawl that excludes loggerhead sea turtles. It turns out, it’s also better at capturing scallops, with the end result that scallopers can use smaller areas and less fuel – 75% less – to make their catch.
