Dear Jimmy from NY with the pond in PA:

Your fish sound as though they are overcrowded. Remove some LMB, and add adult bluegill at least five inches long.

Next spring, when your BG spawn, your predator bass will have more to eat . . . and with fewer largemouth to feed, each bass will get more to eat.

Israeli carp? Have no practical field experience with them.
