Abstract
Community, microbenthic, and planktonic metabolic rates were measured in a Hawaiian fishpond from June 1966 through June 1967. Incident and penetrating light intensity, dissolved phosphate, nitrate and nitrite, and silicate, temperature, salinity, and pH were measured concurrently. Primary productivity and respiration were greatest in the fall and spring. Primary productivity was most frequently limited by light intensity because of the turbidity of the pond water. Dissolved inorganic nutrients did not appear to be limiting. Community respiration exceeded gross primary productivity by 212 g C/m2 yr. Organic matter was probably imported from the surrounding mangrove swamp.
