via Ed Yong, an interesting piece in New York magazine: ‘Bycatch 22 — As a twisted consequence of overfishing regulations, commercial fishermen have no choice but to catch sea bass, flounder, monkfish, and tuna—and throw them dead back into the sea.’
Basically the problem is that, since you can’t precisely target a particular species, fishermen end up throwing back a lot of marketable fish which they don’t have the quotas for — so the fish are just as dead, but no one gets to sell them or eat them.
I have sympathy with the fishermen, and throwing back lots of edible fish which are already dead does seem like madness: but the commercial fishing industry hasn’t exactly proved itself a trustworthy steward of marine ecosystems over the years. They continually campaign against the kind of quotas that would actually protect fish stocks, and they campaign against no-fishing zones, and the situation gets worse and worse.
The really interesting experiment would be to ban commercial fishing around the UK altogether for perhaps ten to fifteen years, and see what the seas looked like after having a chance to recover from 150 years of industrial onslaught.
But then I’m increasingly freaked out by the extent of environmental degradation I see around us, and too much of the time we seem to be doing ‘conservation’ — conserving what’s left — which in practice often just means slowing the rate it disappears at, whereas what we really ought to be doing is restoration. Trying to create more space for wildlife, more opportunities for wild things to scrape a living.
