Nah, read about this in the 90’s (I think?). The article was about a specific Atlantic fish, I forget, been a long time. Scientists were puzzled as to why the fish were shrinking.
Fisherman are only allowed to keep the big ones, throw the little 'uns back. This creates evolutionary pressure for younger/smaller fish to come to maturity and start reproducing sooner.
I toured the Tsukiji Fish Market in Tokyo, right before it moved to Toyosu. The guide mentioned that giant tuna being caught today, as big as they are, are smaller than they used to be.
I want a new Titanic movie, but instead of the Orchestra playing till the end, there should be a bunch of Lemmy jokesters making witty comments in the face of unavoidable doom.
I think most people can agree it’s a combination of pollution, overfishing and climate change. Probably just unclear which one of those factors in the most.
Crazy idea, but what about fishing-driven evolutionary pressure. If all the biggest fish are getting caught and killed, won’t that give smaller fish an evolutionary advantage?
Very possible, but with all things happening it’s pretty hard to be sure it’s that and not fish growing less because they’re being poisoned by microplastics.
Maybe if we’re talking line fishing, but I’m pretty sure most commercial fishing is done with trawling nets, where everything above a certain size is caught.
