As the tittle says anyone here use it?

Basa is a catfish widely farm raised as food fish.

It has clean white meat. There was a thread here a while ago regarding Thiamenses. Cant seem to find it now.
 
anything farm raised will have Thiamenses in it ( If i'm wrong please enlighten me, would save a lot on my personal food bills) because the pellets fed contain them. a quick google search for fish and human pregnancy will give you a good lists of thiamense and fish as its not considered something pregnant women should eat either.

actually mercury.. my bad silly me... I still avoid Thiamense though as it causes similar health issues in humans as it does our pets.
 
I wonder if there has been an updated list?... I knew I read about shrimp here somewhere.. and that would be the article... why I do not feed shrimp to my fish as a main staple. Pollock though is pretty common and reasonably priced around here.... hmm.. atm I'm feeding mainly trout ( cheap and whole fish.. can't go wrong there!) some smelt I got that looked good, and some fillets of natives we catch around here (bass, northern mainly) Glad to know they are low on the pole.

I tend to avoid "farm raised" stuff in general as most the research I've done shows that the quality of the foods used is not as good as what wild is ( and we pay for it) and it impacts the fish. But I'm also an organic eating/growing hippy... lol

Back to your original question... I don't see why you wouldn't feed Basa/swai/tilapia ect.... as long as your mixing it with a good pellet/vitamin suppliment ect. I feed our gar goldfish 2-3 times a month 200+ at a time.. thiamine deficiency issues have never shown.. but I think its because its not the only thing they get and I try to give them as wide a variety in general as I can. And at the end of the day they are piscivores. I've seen these issues mainly in Oscars ( omnivorouse to begin with) that are fed mainly goldfish if not exclusively and a cheap brand of pellets ect.. poor husbandry practices ect... Nothing to counter balance. I found just adding a quality pellet/vitamin to the diet didn't just stop the physical manifestations but improved them (vitachem has saved many a fish I was told should just be put down. HLLE is often the result of this deficiency ime.) But I also believe you can get to much of a good thing and lose other vital minerals ect by feeding pellets 100% Lots of positive steps being made by the companies in creating pellets for our pets but I don't think there will ever be a magic pill for us let alone our pets.

catering to our pets individual needs... if you have fish eaters.. why not try it?
 
I feed them all diff kinds of pellets from hikari with market prawns, smelts, tilapia and some local fishes what we get around here.
Just that my Gar is growing to be a beast and I want something less inexpensive and chunky to fill his stomach.

Thiaminases are synthesized by certain species fish and presumably play some physiological role, though I don't believe it is known what that is. Thiaminase levels vary between species of fish, but I don't believe anyone has demonstrated any connection between thiaminase levels in the flesh of farmed vs wild caught fish. Some of the highest levels of thiaminase activity have been found in wild fish like shiners and shad.

Fish pellets are unlikely to contain thiaminases because they are thermolabile (destroyed by heat) and most commercial fish meal is heat treated to be shelf stable. And even is a fish was fed a pellet containing thiaminases, this would reduce the vitamin B1 levels in the diet but the thiaminases themselves are minimally absorbed in the gut so there won't be appreciable thiaminase accumulation in the fish itself.

Also, as I mentioned before, thiaminases are thermolabile, which means they would be effectively destroyed by cooking so I don't see why this would lead to health problem in humans (unless your entire diet consisted of raw goldfish, in which case you probably have other issues :) ). A more likely source of thiamine deficiency in humans would be a diet lacking vitamin B.
