The Pennsylvania Farm Show is highlighting aquaculture, an emerging industry in the state.
According to National Aquaculture Association, farmed fish can help satisfy the growing worldwide demand for seafood and protect wild populations from depletion.
“A lot of the aquaculture sector in PA is sports fish like trout. There’s some bass farms that grow for stocking,” said Paul Nickerson of Integrated Agriculture Systems.
The aquaculture exhibit at the farm show focuses on aquaponics, or the use of fish waste as plant food, as a way to naturally filter the waste.
