Depending who you speak with - and we speak with absolutely everyone, rising squid populations are responsible for fisheries collapses worldwide.
The theory goes something like this:
Sharks (who eat squids) are being killed off leaving an open predatory niche in the worlds oceans. Unfortunately squids reproduce at the rate of millions and without sharks to control populations, swarms of these critters are taking over delicate feeding chains decimating fish stocks...or so this theory goes.
We submit to this theory, mainly because the folks behind it are smarter then we are. So it is with little surprise that researchers at the Council of Agriculture’s Fisheries Research Institute in Taipei have found the brain boosting compound PL-DHA (phospholipid docosahexaenoic acid) in squid skins.
If you want to eradicate anything commercially from the ocean, you need to first come up a with a financial reason to do so, thank you researcher guys in Taipei. Now we can all be a bit smarter while doing the job sharks used to do before we killed them all off...back in our dumber days that is.
