Plankton normally does not thrive in moving water (rivers) compared to ponds and lakes. Plankton can grow well in rivers but generally it is a lot less than in fertile ponds and lakes. Generally the faster the flow or flow though the less plankton there will be present. Here is some additional reference information.
Slab Lab Bluegill Pond with Sarah Pavin discusses some of the history of her 5 ac pond and her big BG project at time point 6:07. Interesting presentation. On this pond they have 1 auto feeder per acre (5 on 5 acres)
