Both, the Shark Divers and Beqa Adventures blogs picked up on this post from the Southern Fried Science, a South Carolina marine biology grad student. It's a disturbing look at supply and demand economics regarding fisheries and it bolsters my attitudes regarding the importance of developing successful aquaculture. Here's a portion of the post:
"The basic premise is that many fisheries are completely supply limited. Even if we were to reduce 90% of the demand for certain fish, the remaining demand would still be great enough to consume 100% of the supply. If 100 people all love grouper, but only 10 grouper are being produced at any given time, then even if you convinced 90 people to never eat grouper, the other ten would still eat the 10 grouper being produced, and nothing would change. I was surprised that it’s taken me this long to start understanding what that means."
This also relates to shark products, particularly regarding the dollar value that increases with their continuing scarceness, even with reduced consumer demand. You can read the entire post here.
