Annual primary production in meromictic Fayetteville Green Lake, N.Y., was estimated to be 290 g C/m 2 , based on seven measurements by the 14 C method. About 83% of this annual production was due to photosynthetic sulfide‐oxidizing bacteria in the chemocline at 18–20‐m depth. Zooplankton densities were higher near the bacterial zone. Bacterial photosynthetic production and concentration of mixolimnetic seston at the chemocline provided adequate food for a relatively large zooplankton population. Evidence for diel migration was observed among the zooplankton.
