After draining down my pond, I walked over some of the exposed shoreline today. There were oodles and gobs of snail and small mussel shells. That should be good food for the redears; but also bad as part of the cycle for the grubs that infest fish through birds / snails / fish, right? Any thing I should do as a result of finding all these?

Consider adding some more RES (when you refill). A healthy population of them will cut way down on snails. Mussels, I don't know - how big are they?.

Most looked to be about 1/2 inch. Largest looked to be slightly over an inch.

I'm expecting to sooner or later end up with mussels in my pond. I'm only 1/2 mi. from a river that has them so I'm also curious as to what to do when they come. If it were here I would say the 1/2" to 3/4" mussles were just babies. I see them in the river 4" to 6"! Ranger, maybe you could start a pearl farm? Japanese prefer fresh water mussels for cultured pearls. Here's a link to Illinois mussels: http://www.jaxshells.org/dhess.htm Certain species seem to attach to only one or two known host fishes, whereas others can use numerous hosts. A few such as the Squawfoot and the Pond Paper Mussel do not seem to have an obligate parasitic stage for the glochidia. One species is known to attach to a salamander, the mud puppy. This mussel is Simpsonaias ambigua (Say). Obviously, those mussels which have the twin good fortunes of wider habitat tolerance and larger numbers of common host fishes are at a greater advantage for maintaining large populations.

I remember reading somewhere that BG will also eat small snails. I'd really rather not have them but have no idea how you can prevent them.
It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Bill Cody told me it may depend on the snails. I have two species in my ponds. Bill says one the fish like because it is easy to crush. The other is not.
If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.

They can eat zebra mussels.
Centrarchids 1l centrarchids have upper and lower pharyngeal teeth (Figure lb), but molariform teeth are present only in redear sunfish (Lepomis microlophus) and pumpkinseed (L. gibbosus) (Trautman 1957). Mollusk-eating in centrarchids is usually associated with increases in (1) proportion of molariform teeth on the pharyngeal jaws, (2) width of lower pharyngeal pads, and (3) thickness of several pharyngeal muscles (Lauder 1983). Predation on thinshelled gastropods by these sunfishes is well documented (Carothers and Allison 1968; Laughlinrr and Werner 1980). The redear sunfish is capable of eating bivalves up to 5 mm long (Britton and Murphy 1977). In experimental tanks, adult redear sunfish 18 to 26 cm long fed on zebra mussels up to 20 mm long, and a 7- mm-long juvenile ate young mussels under 3 mm long U. French and M. Morgan, U.S. Fish and Wildlife Service, unpublished data). Zebra mussels were found to be common in the diet of pumpkinseed in the Crapina-Jijila Pond flood area of the Danube River delta in Romania (Spataru 1967).
