Is it ok to feed them on Sprats?

[Stefan-A]

My pc is lagging too much to look it up (cant open any tabs or windows while I'm backing everything up) but, the silversides that are in Sally's silversides are what I'm talking about.

Ah, yes. That would be another exception.

I meant the Osmerus eperlanus.
So you say there is no thiaminase in this fish species?
Here it is considered by many people to contain thiaminase.
Is there any research done?

I should have an article somewhere, but I'm not going to try to look for it.

Aw, Stefan... You're getting lazy! I'm interested in learning, and you're smart, so... Get off your behind and find it!

Stefan, if you say that there has been research about it, then that is enough for me. I believe you.

I feed my garter snakes for 95 % with Osmerus eperlanus and I add no more than a little bit of thiamine every 5 to 7 feedings. And I have never had any problems with that.

By the way, isn't it so that the thiaminase in a fish destroys the thiamine in the fish after it is dead. And does not affect the added thiamine?

Your own experiences weigh more than just my word. I could be wrong.

Then again, you could just be lucky.

OK thanks everyone, I think I'll just avoid sprats then.

[Thamnophis]

Don't believe that is luck. I raised a few hundred juveniles from more than ten (sub-) species on this diet and have never seen any sign of thiaminase. So it's fairly safe to say that the European Smelt is a safe fish to feed.
