I dislike wanton waste of a resource. I don’t know anything about paddlefish, but what are those guys going to do with them? If they’re fine table fare, whatever, but something in me doubts that. They are like flatheads in another way – if you want a mount, you pretty much need to get a replica made, so keeping the fish for that reason isn’t necessary.
I know it’s legal, but I think most people that catch big cats and keep them do so because they’re excited about the size of their catch and just not able to put them back into the water – around here anyways – I know in the south they do tend to keep ’em big. The people that keep them out of amazement probably don’t put them to any good use.
I’m against the keeping of large predatory fish for another reason, too – they’re less healthy to eat. Methyl mercury is a nationwide problem, spread in the air from coal burning. It bioaccumulates, so any predator (or eater of filter feeders) is going to build up a high concentration. Trophy predator fish are older and have had more years to do it – especially slow growers. The mercury may not affect the fisherman him/herself, but it will affect children and especially buns in the oven, who are especially susceptible, and I don’t find it ethical to put them at risk of brain development complications.
I get along with anyone and I know it’s people’s right to do what’s legal, but I don’t have to pretend for a second that I agree with it, and I won’t. If people want food fish, keep the smaller fish – they taste better and are more numerous to begin with, and they’re less contaminated.
To me, “ethical” equates with what’s good for the long term health of the fishery and the people who use it. By that standard, what is legal and what is ethical are far from one and the same.
