Tilapia mossambica (Peters) fry were reared in tank microcosms on the proceeds of in situ algal photosynthesis only. The cube root of average rate of individual weight gain was related linearly to average rate of gross photosynthesis. Failure of increased population density to suppress individual growth rate was attributed to inefficient foraging and rapid decomposition of uneaten settled phytoplankton.
