Pond Boss Forums INTRO Questions & Observations Bass spine curvature?

If these were initially stocked bass, IME it could be from damage that occurred in transport (which would be debilitating in a stocked pond, but poses less of a problem in an empty one). I found a larger-than-expected number (basically meaning non-zero) of deformed fish in both my pond's initial stockers.

If this is occurring in bass spawned in an established population, my guess is you have some weird genetics going on.
