ANOMOLOUSLY LOW EGG PRODUCTION RATES BY ACARTIA TONSA IN FLORIDA BAY: LINKS TO SESTON NUTRITIONAL QUALITY
 
Studies in Florida Bay during summer 1996, revealed anomolously low egg production rates (EP)by Acartia tonsa. We tested the hypothesis that low egg production rates by copepods in this perturbed estuary are associated with seston nutritional quality. Ingestion rate (IR), EP and seston-protein, lipid and carbohydrate concentrations were measured off Rankin Key, a perturbed site, and Duck Key an oligotrophic site, from July 1997 to May 1998. Off Rankin Key, IR averaged 163% of body C/d but EP was <15 eggs/copepod/d. Off Duck Key, both IR and EP were low. Factor and regression analyses indicated temperature- and food-limited egg production at Duck Key. While EP varied with seston protein levels at Rankin Key, unusually low lipid levels appear to set the upper limits on EP at this location.
