FYI: Gammarus fasciatus is available from Wildlife Nurseries,Inc, POB 2724, Oshkosh WI 54903-272. 920-231-3780. They do not ship until around May when their ponds open up. Price is $75.00 for 200; including shipping. I have bought Gammarus from them, product is good.
G.fasciatus gets up to 14mm long whereas G.lacustris gets up to 22mm long. Other than that they are quite similar in overall appearence.
The place in Ohio said will ship papershell crayfish but they said overnight shipping gets expensive. So far they have only shipped them within Ohio. Regardless of how bad one wants them as fish food, I would not import them into states where they do not already exist. There are other crayfish species that will serve your purpose. Even collecting local crayfish from your local streams or marshlands would be a much better alternative.
