Another consideration is that raising the temp of cool water species affects their physiology. Amino acids, hormones, omega-3 levels are adversely affected if temps get too high to maintain proper osmotic regulation and digestion. Immune systems and blood regeneration are also adversely affected. With species such as sturgeon, it's always better practice to adjust the environment to the fish instead of forcing the fish to adjust to the environment. It's exceedingly difficult to try overriding millions of years of evolutionary-set patterns.

so the fish would go CRAZY inside and out? like what would all those changes do? if u dont know thats fine, its just this all sounds really interesting.Oddball;1103651; said:
In young sturgeons, they'll usually fold well before the above listed issues arise. I've seen way too may fingerlings "fry" their brains when maintained in temps warmer than they require. I've done a few necropsies that showed swelling and blood in the spinal column. I'm sure there's a protein breakdown that acts as a cholinesterase enzyme inhibitor. The symptoms can be observed as whirling disease (with the absence of bacterial infections), tank side ramming, and nose bobbing (fish appears to be constantly trying to swim up from the surface for no particular reason)

How would that matter?
They're fingerlings while they're about the size of a finger. But, they're still juvies until they reach about 20"-24" and have developed fat reserves and efficient immunity systems.
And, I don't 'get them in', per se. I'm not a dealer/importer.
