Benthic samples were collected monthly during 1978–1979 at two sites in a tropical stream in Palau, Caroline Islands. Secondary production was measured by the size‐frequency method. At both sites, a riffle and an outcrop, the majority of matter and energy flowed through the decapod crustaceans, especially the shrimp Atya pilipes. Atya had a univoltine life cycle, possibly tuned to seasonal precipitation changes. The highest annual benthic production in this stream (7.70 g· m −2 ·yr −1 at the outcrop) did not differ greatly from production estimates in some temperate climate streams.
