These are a fish that sould be left in nature. They cannot be handled, otherwise they loose all their scales and die quickly. The last yacht I captianed had a several hundred gallon live well, two of them. You could crawl up in these things easily and have a party. We tried several times to keep herring alive in these big tanks to use for live bait. Never worked very well at all. Also, these fish have extremely fragile jaws. I don't see how you could catch them without damaging the fish. I also don't see how you are going to feed them and what you are going to house these in? You can't keep every fish that catches your eye.
