Kinda funny, but it is all perspective. Some people would be thrilled with what you have. It's not an exact science but you can alter the classes of your fish. If you don't want to take bass out, but want unskinny bass you have to feed em. You need to establish ready to eat forage. With a pond/lake that size you must have a cove or isolated area. Can you load up on baitfish? Net off an area and start your own hatchery? Make a seperate pond? Something self sustaining no tilipia up there in the snow.
