I always catch my own minnows. I bought a cast net, egg sinkers, and some large styrofoam floats. I cut two sticks about five feet long and I strung the net between the two sticks with the floats at the top and the egg sinkers at the bottom. Then I got the small branch below my home and find a deep hole, putting the sein on the bottom and holding it tight I work from one end of the hole to the other when i get to the end I sweep the net closed and lift. I can usually catch thirty to forty dozen in fifteen minutes. This is a hard skill to master and I am far from matering it but I get the job done and save my money.
