I read an article today about largemouth bass having problems with swim bladders when they are caught in deep water and reeled quickly to the surface (their swim bladders expand from the decrease in pressure). Do carp and buffalo have a similar problem?

Theoretically, it could happen with just about any fish. I haven't seen it with carp or buffs, but I haven't pulled one out of 60 feet of water, either. I think 35 feet is about the deepest I've ever caught one. It seems to me that, since they come up slower, rather than being just pulled up like a bass, carp and buffs may be able to equalize a little better.

Yeah, I think since unlike most Largemouth Bass, Carp and Buffalo actually make you FIGHT them in, stripping a lot of drag and battling you, their swim bladders have a little more time to equalize to the different pressures of various depths.

I've caught both carp and buffalo from 60 feet of water at PK and never noticed any problems.

The article I read said that some fish, like trout, have a different physiology that allows them to compensate more quickly for changes in pressure. Maybe carp are like that.

Another article I read said that some fishermen at the Great Lakes catch lake trout from depths of several hundred feet (maybe as deep as 600 ft). Many of the lakers have been caught more than once, so they've evidently done just fine.
