On the topic of stunting in aquariums, I also have to note, about 5 years ago, before I knew ANYTHING about fishkeeping (you put the food in and enjoy!!!), I used to have a 29 gallon tank with 2 oscars, a rock bass, a redbelly pacu, a common pleco, and 4 blue paradise gourami. All fish were purchase as juvies. when I got rid of the pacu it had grown to 14" long(and 12" high, I was having to hand feed it shrimp pellets, as it couldn't move...), oscars were both 10" long, and the pleco was 12" long. I was massively overfeeding them and water changes were MINIMAL(when the water got so dirty I couldn't tell if the lights were on, it was time to change the water). While it's granted that this was only ONE tank, over about 1 1/2 years time, I think that kind of tells me it takes more than just poor tank conditions to affect growth rates of fish.

The oscar I used as my example of growing to 10in in a 10G was in the same basic environment..early 80's I didnt know anything of water changes or size vs tank requirements, I think it also has to do with captive breeding producing weaker specimens..One of the Oscars I have now even with pristine water conditions constantly shows signs of HITH, the other one shows no signs of it, I have been doing water changes every other day for a while and it got to the point today I had to seperate him because the smaller on was taking advantage of his weakened state..

Anyone want to answer my previous question? I have a pond in the several thousand gallon range. If I cleaned out all the plants and potted them up and left lots of open space do you think a paddlefish or two would do ok?
I would like to hear more from bigfishfarms and sure hope they haven't been scared away.

A couple of paddlefish would be fine in that environment. Realize that 95% of the people we sell fish to for ponds never see their fish unless they continue to pellet feed at night.
Not too sure.
Pond is liner pond with sloping sides that could be additionally cushioned if that was necessary.

I learned an interesting lesson about trying to house a fish thats eventual size, far exceeds its available containment.
Early in my fishkeeping years, i had accumulated a nice selection of african cichlids, which represented a lot of travel to many LFS, cherry picking if you will.
My grandson convinced me that we needed that cute little red tailed cat in the tank to give it more species variety.
To make a long story short i ended up with a huge catfish, that was full of all my beloved cichlids, and miserable as well due to cramped condidtions.
Moral is.. new fishkeepers simply do your homework, Know what youre willing and able to provide by way of housing before you buy.

There seems to be a lot of interest in "how big do fish get in captivity" lots of differences of opinion about why or why not fish get to be a large percentage of their maximum wild size. In my experience you can keep fish in great water quality and feed good nutritious foods, even live foods and still end up with a fish much smaller than it's maximum wild size.
As a point of evidence I have kept many iridescent sharks that stayed way below their "max size" most staying well below 12" and most in the 8 to 10 inch range. Even though the fish enjoyed summers in a large yard pond and winters in a 125 gallon aquarium with surface water return and trickle filtration the fish never grew past 12" or less.
It's my hypothesis that these fish become stunted when very small by being kept in a small aquarium where the pheromones they give off to adjust their growth rate keeps them from growing. later even if introduced to a larger habitat they still seem to keep their small size.
What are some possible mechanisms that would allow this size disparity to come about? Does this work on all fish or just some fishes? Are the fish raised this way on purpose as healthy and long lived as their wild counterparts? Is their anything wrong with adjusting the size of the fish to fit the aquarium rather than going for some arbitrary large size in captivity?
I am going to post this in the fish keeping threads since this is off topic from the OP.

I wonder about this too Moon, but I am going with just "variation" there are more fish that are average size than there are that reach maximum size. Often the max size gets reported, just because it is true that there has been a specimen that was seen at that size. But "most" individuals don't get to that size. And I don't blame the people that report them... if they didn't someone would be calling them up telling them their data is crap becasue they have "proof" that the fish can get bigger than that. Again, true, but not necessarily the common size.

bigfishfarms: You don't think they would be visible? The pond is not much deeper than 4 feet in the middle and probably 20 feet across at the widest point. Also since paddlefish ram ventilate wouldn't they be constantly cruising back and forth and thus easy to see?

I'm thinking of putting some of the paddlefish i have into one of these preformed ponds, about 300 gallons. From what's I've seen in captivity so far they should do well but unless the water is ultra clear seeing them will be problem, they are black as is the pond, not sure they would show up well against the dark back round....

Michael, what about a blue preformed kiddie wading pool? I've seen four, five, and six foot sizes available.

I use the snap set pools quite a bit, a 8 footer holds about 300 gallons, they last about 3 years if you are careful and don't walk around in them much.... But as stuff accumulates on the bottom fish get hard to see in them too...

RE: JUVENILE PADDLEFISH FOR SALE IN THE UNITED STATES.
I'm not sure that anyone will ever see my post here (at the "bottom" of thread) , but I'll give it a try anyway.
I have briefly reviewed some of the posts relative to availability of paddlefish juvenile and their very high prices. I would like to offer an economical alternative and a very reputable aquaculture producer supplier for enthusiasts who may have interest in purchasing a reasonable minimum quantity of specimens { 25+? }.
I am an aquaculturist and fish farmer. Two years ago, I purchased more than 100 juvenile paddlefish from this same producer in Kentucky who spawns and raises these fish every year. My fish were introduced into my system as part of a polyculture trial.
Kentucky producer raises paddlefish often used/distributed/sold for research purposes, but he also sells his surplus stock every year, and at very reasonable prices. These are not "dwarfs", "dinks" or "runts"... these paddlefish are probably going to be healthy 8"-12" feed-trained juveniles from native broodstock and the price for orders of 25+ fish is approximately $10 each. If there is a buyer who desires to purchase 1000-5000+ paddlefish, that quantity of fish is likely available provided that some advance reserve notice is delivered to producer. I speculate that some manner of reduced pricing would apply on those large purchases.
USA buyers will need to drive to Kentucky to pick up their paddlefish, or may choose to hire an aquatic live delivery contractor. If you can personally make the drive to Kentucky to pick up your fish, you'll have the opportunity to ask questions and learn about this species from a bona-fide and admired paddlefish expert.
If this is of interest to some readers, please communicate to me and I will attempt to assist.

Yes, It was nice talking to you as well. My name is Matt as you know, and I am a volunteer on our board of directors. Matt is just fine. Half the time I am referred to as DLV and the rest of the time I am referred to by names that I probably should not repeat in public. I appreciate the show of respect, but Matt or DLV seem to work.
I will be back in contact in the next few days. I appreciate you making this offer. This will likely make some members with larger systems very happy.
Please feel free to stick around Mike. Lots of info here.
Thanks. Matt
