My experience is that with too many cats and too little food the cats will work in the sediments for food items. Cats are able to feed well in cloudy /silty water but other sight feeding fish do not usually get adequate amounts of food when water has visibility less than 15-20 inches. If your pond water does not settle out and become clear in the jar test then assume it is due too many catfish. If your LMB population is not abundant enough with good survival of bass spawns then the catfish reproduction / survival can become a problem with too many slow growing cats.
