RE: The Holocene Mass Extinction Part 3: Climate Change
Whoever messed with the abundance of old style sardines - those two-an-a-half-inch ones with a delightful flavor somewhere between modern-day 'pilchards' and good old anchovies, is certainly not popular with me. And whoever can engineer them back into an affordable bracket will certainly deserve that most highly esteemed SteemNobel Award!
Find a way to halt severe overfishing, and we're set!
Regulations are not enough to stop over-fishing as it's almost impossible to get a worldwide regulation... Also, el niño years do not help the population of sardines (even though it slows over-fishing for them down a tremendous amount).
We need to save spiny and smooth dog fish (not even that closely related despite similar common names) from over-fishing too.
Worldwide regulation actually isn't necessary- the establishment of marine wildlife preserves generally does the trick. Fish populations restore rapidly inside them, then spread outwards from there. Plus, fishing bans in a specific area are pretty easy to enforce.
There are literally hundreds of species at risk from being overfished. 90% of all large bony fish by mass have been taken from the ocean in the last century. It's an extremely dire situation.
