We didn't have to purchase ours. The mosquito abatement program from Yolo County planted 100 in our pond to prevent the spread of mosquitos in our area. The mosquitos really weren't a problem, but they want to be cautious I suppose. :rolleyes:
OH well, now I'd like some feedback on the second part of my question. What type of fish (black bass, striped bass?) would be good to add in a limited number (one or two?) to keep the mosquito fish population in check? Will the blue gill/sunperch family of fish that we already have in the pond do this? Will the bass "bite" any swimmers?
