Cheapest price I have found is about $6-8 for a trap ar Wal-Mart and a couple bucs for some cheap dog food wink They are very easy to trap, the only problem is the potential to carry disease to your pond. I wash any and all that I catch in water from the pond before I transplant them. Also, it can be rather time consuming to go through and identify every one you catch, just to make sure you don't get a non-target species, like the Rusty, in with the bunch. Lots of labor, saves on money. There is a link above where you can have some shipped to you. A little pricey, but saves you the trouble of the above activities. Otherwise, call around to fish farms near you and see if they can get them for you.
