Two small adults from the open water habitat contained 90% copepoda and cladocera while inshore specimens contained 90% fruit, 5% cladocera, 5% seed, algae. The adult female from open water contained ripe eggs, although10 adult females from inshore sites contained only undeveloped eggs (Ref. 83537).
