In 2019 the minnow populations in the Dakotas and Minnesota were very low as a result of a severe winter kill. This caused a significant price increase in 2019 and it is unlikely that the wholesalers will bring the prices back down even though we expect the availability to be inproved in 2020.
Demand for yellow perch has been strong and we are trying to increase our production to meet that demand. We currently have a good supply of yellow perch that are feed trained. Their optimal growing temps are 68 to 73 degrees which works out well for many aquaponic systems.
As of the end of February 2020, we have been unable to replenish our supply of blue gills and pumpkin seed sunfish. We will continue to look for a source for those two species.
