Between Primary Production and Mosquitofish (Gambusia Affinis)
Production in Large Microcosms
Phillip Goodyear, Claude E. Boyd, and Robert J. Beyers
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 O2 and
pH-Co2 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.
