how about thisWhat fish are you feeding?
Many "silversides" that are being fed are actually types of smelt and are high in thiaminase, so unless you know for sure, it's best to avoid that "species name" altogether.
Here is my list of seafoods that are lower in thiaminase. Guppies and poecilids would be your easiest substitute for silversides. All seafoods should be augmented with vitamin E though....
Species lower in thiaminase
Atlantic cod (Gadus morhua)
Atlantic hake (Merluccius bilinearis)
Atlantic halibut (Hippoglossus hippoglossus)
Atlantic mackerel (Scomber scombrus)
Atlantic salmon (Salmo salar)
Brown trout (Salmo trutta)
Catfish (Ictalurus and related spp)
Cisco (Coregonus spp.)
Coho salmon (Oncorhynchus kisutch)
Flounder / sole (Pleuronectes and related spp.)
Haddock (Melanogrammus aeglefinus)
Hake (Urophycis spp)
Lake trout (Salvelinus namaycush)
Mullet (Mugilidae spp)
Poecilids (Guppies, platies, mollies)
Pollock/Pollack (Pollachius spp.)
Rainbow trout (Oncorhynchus mykiss)
Tilapia (Oreochromis spp)
Worms (Lumbricus spp)
octopus
squid
cuttlefish
whole prawns with shell
sockeye salmon
clam meat
half shell mussels
Cod roe (UK waters)
