The secondary production of the harpacticoid copepod Paronychocamptus nanus (Sars, 1908) in a shallow, brackish‐water pond was estimated during spring and summer 1980. The population was sampled every 5 d. Production of copepodites and adults, calculated by the size‐frequency method, amounts to 1.91 g m −2 dry wt over the sampling period (March–November). Egg production is 1.23 g m −2 ; naupliar production is roughly 1.09 g m −2 . The production efficiency (ratio of production to production plus respiration) of copepodites and adults is 0.37; for the total population it is 0.42. P : B of the population is 24.45 over the sampling period, or 3.2 per generation.
