I bought a net like yours but need help setting it up. Do you mind to post your trap? We have 3 or 4 different types but catch no croppie. Your pond is mostly a croppie pond, I belive isn't it? My pond floods sometimes and there are at least 20 species that we have caught out of it. We have too many cats also and have taken out 245 this year so it is a lot of work to try to keep up with them.
