One problem is that fisheries often target what scientists call BOFFFFs: big, old, fat, fecund, female fish. Their large bodies are prized by fishers, but BOFFFFs are a vital source of new baby fish. Take these away and the size spectrum quickly veers out of kilter. One way to manage this is to encourage the fishing industry to target medium-size fish, allowing mature ones to replenish depleted populations.
In 2017, 34.2% of the fish stocks of the world’s marine fisheries were classified as overfished, a “continuous increasing trend” since 1974 when it stood at just 10%.
Climate Change “Whittling Away” at Marine Diversity

Report: Illegal Fishing by Chinese Vessels in West African Waters
“China is exporting to Africa the kind of destructive fishing practices that depleted local fishing grounds off the Chinese coast,” said Rashid Kang, the director of the China Ocean and Forests campaign at Greenpeace. “At a time when China talks about win-win partnerships with African governments and is concerned with improving its international image, these kinds of practices damage marine resources, threaten local livelihoods and undermine China’s soft power.”

Report Exposes China’s ‘Shady’ Fishing Industry
Reporting on international fishing can often feel like investigating organized crime. Everyone knows how things are run, but the truth is obscured by shell companies, back-door dealings, and plausible deniability. This is why it’s remarkable that a recent, bungled initial… Read More ›
