What do the fish below the thermocline eat if hypolimnetic aeration is effective at oxygenating the deep section and it stays cold? I assume they do not cross the thermocline to the surface to forage where the food is.
Although coldwater forage fish are optimum, in our northern lakes that have a "two tiered fishery" aka two story lakes, the trout feed on a lot of invertebrates on the bottom and surprisingly even the larger fish are good zooplankton filterers in the water column.
