ok thanks...you asked if i have bluegill in the pond. i know there are alot of large ones but i never catch any under about 6inches or bigger. also with the sancuary idea how would i guild it. like would i use like a mesh net like a sein or wat for the wall and how would i make it where it does not move or come up. after minnows substain population should i remove the net so the minnows will be all over the pond or leave it there? also about how big of area should it be and in how deep of water. also to start this how many minnows should i get inorder to make shore enouph stay in that area and dont wonder off and me have to get more again
