Mosquitofish were raised in 244‐cm‐diameter pools which were fertilized with different levels of commercial fertilizer to establish various levels of primary productivity; this was measured during summer by both O 2 and p H‐CO 2 estimates. Mosquitofish and the residues of organic matter accumulated in the pool bottoms were harvested at the end of the experiment. Mosquitofish production was highly correlated with net and gross primary productivity as measured by both techniques. The production of mosquitofish was more highly correlated with the amount of organic nitrogen in the residue than with the total amount of residue in each microcosm.
