Also to release into local water, you might have treated it with some chemical that changes or contaminates the fish, or as previously stated diseases.

Release ain't happening. That was a provocative statement which I retracted.
But, for the sake of a friendly argument (realizing it's illegal without a permit), state and federal hatcheries do it all the time. I don't believe there is a reason why native fish can not be released into their native habitat IF proper protocols are followed such as avoiding sources of contamination (biological/genetic as well as organic), following a quarantine procedure, and doing so only with proper state and federal approval.

Anyone know how to determine the sex of paddlefish? If so, what's the earliest age/size they can be reliably sexed?
(This is a serious question so no answers like, "Just jump in the pond and see who swims between your legs")

Jeroen, Are you saying they can not be sexed until 6 years of age?
What distinguishes males from females? Are females more robust and males more slim?
Any other signs like finnage in cichlids?

Anyone know of good reference books on paddlefish?
I just ordered this one from a 1986 symposium of the American Fisheries Society:
The Paddlefish: Status, Management and Propagation by Joe G. Dillard, L. Kim Graham and Thomas R. Russell, eds.
There's 2 others, much pricier:
Paddlefish, by Surhone, Lambert M.; Tennoe, Mariam T. and Henssonow, Susan F. and
Sturgeons and Paddlefish of North America by Lebreton, Greg T.O. (Editor), and Beamish, F. William H. (Editor), and McKinley, Scott R. (Editor)
but I can't find any information about them. Anyone familiar with these books?

Here is a good description of many aspects of paddlefish culture by the Southern Regional Aquaculture Center (SRAC), University of Kentucky, 1999:

It does corroborate Jeroen's comment about sexing, stating that the fish must be sexually mature, 6-7 years old.
There are also a ton of videos on youtube. Apparently paddlefish is a popular food fish in Asian countries, with the taste and texture of pork.

Nice thread man. The paddlefish is a truly magnificent and fascinating fish it's a shame that that those alien carp in U.S are outcompeting them for food in some rivers.
But the saddest to me is that due to dam building and poor river management, possibly the largest freshwater fish in the world (the chinese river sturgeon) is probably already extinct.
I wonder if it is possible to clone them using the american paddlefish?

No it is not possible to clone them using the american paddlefish
Yes they are related but not close enough and the american paddlefish is a filterfeeder but the Chinees is a bottemfeeder
The most importend why they are already extinct is that they cannot get to their breedingground and feedingground and than we dident talk about fishing ,water pollution by chemicalplants and citys and also farmers
The last seen one was in 2003 and that was a male they have release it becose a coppel of months before the male they had a big female and it die becose it cannot cope whit living in captivity
There are more sp of Sturgeon that are great to see but also will end up like the chinese river sturgeon
The Paddelfish
alien carp in U.S are outcompeting them for food in some rivers What types of Carp
Paddelfish feed on they eat plankton and mosquito larvae, crustaceans, and floating eggs and baby fishies
I think that the Alien carp is one of much more imported species that now take the upper hand like snakeheads a big part of te reason is
And also fishing ,water pollution by chemicalplants and citys and also farmers ore people who throw rubbish in the water and of course not forgetting the dams putting the species already under pressure , and this all togetter can give the same result like the chinese one
Kind Regards Jeroen
