Watched the Trophy Cachers drop it in the ammo can (at #2 of the multi), and picked it straight back out.
I'm not a fisher, but our next travels are likely to take us along the CT coast so I'll find a nice cache there to drop him off in. As for being bit ... I knew something was nibbling at me as I walked - I thought it was mosquitoes, but I guess it could have been the fish all along.
