|Abstract:||Spawning season, size at first reproduction, oocyte maturation, fecundity and spawning frequency of Eleotris sandwicensis, an amphidromous Hawaiian gobioid, were studied from July 2004 through December 2005 in Nuuanu stream, Oahu, Hawaii. The smallest male and female fish with mature gonads measured 54 mm standard length. Ripe individuals were collected in all months, and gonadosomatic index was highest in males and females from June 2004 through February 2005. Size-frequency distributions of measurements of vitellogenic oocyte diameters and microscopic observations of oocytes indicated this species has asynchronous oocyte development. Estimates of batch fecundity ranged from 5000 eggs to 55000 eggs. Batch fecundity was positively related to standard length, wet weight, and ovary weight, and inversely related to oocyte diameter. Eleotris sandwicensis appears to be capable of repeat spawning.|
