Fishhead :

I agree with Bill adult RE would be best. I had a problem finding adult fish once . I asked the local hatcheries if I bought some 2in. this year and next would they sell me a few, 20 in my case, adults to help with establishing a population. When I told them if they ever needed to get a few adults back from me in the future I would give them 20 back for free they were happy to help. Don't know why they said ok . Maybe they wanted a satisfied customer or to be left alone.The 20 adults I got were not overly expensive and were from the next spring's class not from the suppliers existing brood stock and after I paid for all on the front end { at my suggestion }. This might fit your need if you are going to buy the 2in. anyway.Thanks --ewest
