This is the type of things that ruin the hobby, all over a about $1500.00 of yellow tangs.
Not sure where or how you're coming up with $1500.00. This could be looked at as a retail price tag of about $21000.00!! Yellow Tangs typically sell for well over $35.00 retail, though you can find them cheaper, or more expensive. Every once in awhile, there's an online retailer that blows them out at $19.99, which is still a cost of $12000.00. Les typically sells small Yellow Tangs for about $30.00, according to several of his posts. I'm sure larger specimens get a larger price. From the original incident, and photographs of the dead fish, it appears that there are lots of different sized fish, ranging from large, show specimens, to tiny ones.
This new regulation will impact the ratio of Yellow Tangs captured, as well. It puts a more strict limitation on large Yellow Tangs. This could result in more tiny Yellow Tangs captured. This could result in higher mortality for a couple of reasons. Smaller tangs are less likely to survive transportation, acclimating to collector, lfs and finally hobbyist. Smaller tangs, seen in LFS tanks, will also encourage more uninformed hobbyists to place them in smaller tanks, which will lead to higher mortality rates and less healthy fish.
On the other hand, it will result in less capture of sexually mature specimens, leaving more fish able to spawn, in nature.
I don't look at it as a money issue. IMO, it's more of an ethical issue. Granted, this could have been an innocent, though tragic event, caused by a collector's tanks crashing, killing fish collected over a period of time. However it happened, it does have a negative impact on our hobby, and all things related to our hobby. Locally, in Hawaii, this caused a HUGE uproar against our hobby. I'm sure it had a potential negative impact on the future of ornamental fish collection and collectors.
