Depending on the species of daphnia water flea that you buy and or stock,,,, the species of plankton filtering fish that you stock, and the amount of weed cover available will determine which species of zooplankton will survive and thrive in the pond. I do not recommend buying Daphnia magna who are too easy for fish to eliminate. Then the algae based productivity will determine how many and who are present during the four seasons to contribute to the plankton / pond productivity. Most zooplankton have seasonal density pulses. Type of habitat and species of fish mostly govern the zooplankton community composition.
