Given your original post stating you have a new pond, am I right in guessing you don't have much for vegetation growing in or around your pond yet? Grass carp do not eat all types of vegetation either. I'd vote to hold off on putting any in for now, or at least putting very few in.
You might consider building your forage base before stocking your bass species of choice. BG (bluegill) are often used. Give them a season to establish and reproduce and then stock the predator species.
Lots of good info here in the different sections of the forum. You can also use a search engine like google, type in your question and one space after your search words type "site:pondboss.com" (minus the quotes of course). Works well to thin down your reading in the forum.
