Hello, We wear out the yellows at my duck lease pond north of McKinney, Texas. The lake is about 30 acres and is a "soil conservation" pond. Very silty and low amount of vegetation. The issue is that we catch 5-6 fish an hour on nightcrawlers, but they rarely get over one pound. We have fished all over the lake and rarely catch anything of decent size. Should we start pulling out all these little fish in hopes we can grow some decent sized ones? Thoughts?
