Why are there fish size limits?

I don't fish very often, but this week I went on a chartered trip. We caught a bunch of red snapper, however most we're thrown back because they were too small. I noticed that nearly all of the fish we threw back ended up floating belly up, or were not looking well when released, probably not surviving. Which to me seems counter productive. The ones that went belly up obviously will never make the size limit, so why not keep them and eat them. So why not just have a number limit? Who came up with these regulations? Can they be changed?

Well I would say go look at how the NOAA and the feds come up with these regulations, but their data is crap.

Now as for Louisiana...they have developed a new, better survey (LA CREEL), that is supposed to provide better data for the state of Louisiana.

This is so that the state can make better informed decisions (like opening LA snapper season year long, instead of just weekends only).

Your question is a valid one, and I'm no biologist.

Assuming the agency that is making the laws has good data, good intelligence, and a good understanding of the situation, (WHICH IS A HUGE ASSUMPTION that is worthy of questioning regarding any organization, much less a governmental one, not to mention the political forces involved), size limits can have a positive effect.

Size limits are designed to assist a certain age/size fish.

If all you're catching is throw backs, and you see they're dying as you throw them back, hopefully you will CHANGE your tactic. If the limit wasn't there, you would not change your tactic, and stuff your ice chest (and so would hundreds/thousands of other fishermen.)

Unfortunately, the fish you mention, Red Snapper is right in the middle of misinformed data and imo, a battle between recreational and commercial fishermen.

Throw in battles between state and federal agencies, and federal money supporting state programs, you have quite a mess.

Poli board?

That's why I've always been in favor of a number limit and not size limits. Just like the bullshite with duck hunting and shell limits. Just more cripples out there to die.

in reality (biologically speaking) size limits are used to help the breeding populations of the species of specific fish to remain stable so that the recruitment of new younger cohorts can keep the stock population from failing.

Recently found to be irrelevant with bass in La. At least they are doing away with slot, I heard.

I've often wondered why there is no size limit with crabs.

Ehh, I think you misunderstand. I assume you're referring to the study on and removal of the 14" size limit in the basin and the recent removal of slot limits on some lakes/reservoirs in LA.

The 14" size limit didn't work in the basin because by the time the bass in the basin were old enough to reach 14", there usually had occurred a catastrophic environmental event that destroyed most of the adult bass population (hurricanes). Thus, only a small percentage of the bass population reached harvesting age.

Slot limits don't work because bass fishermen in general don't keep their catch, and the only way a slot limit will be effective is if fish under the slot are kept thus reducing the competition for the medium sized bass allowing them to grow into overs. Since no one was keeping the 12" fish, there was too much competition to efficiently grow trophy bass.

This is not "irrelevant with bass in La" it is irrelevant in bodies of water where fishermen don't keep under the slot fish.

There is a size and bag limit for crabs.

Why didn't the captain or deckhand deflate the throwback snapper first? Thought that was a rule for undersized snapper and grouper so they can be decompressed, otherwise they're as good as dead.

I know there is a possession limit but there is no size limit for recreational.

Very likely. I'm no bass fisherman, just remembered hearing that.

Yeah but you can't take the females with eggs...breeding reasons, just like fish size.

That's pretty shitty they let them go belly up. I've chased floating snapper in my boat for up to 30 minutes before to make sure they go down. That captain is a dick.

I had a drunk buddy jump in to revive a 20lb er and make sure she went down.....(I told him he was lucky he didn't get bit by a shark or raped by a dolphin.)
