Abstract

Marble goby Oxyeleotris marmoratus (Fig. 1) is a freshwater (FW) Eleotridae widely distributed in Southeast Asia and is the most popular aquaculture species (US$50-60/kg). Even though early life stages of marble goby have been studied (Senoo et al. 1994), high larval mortality presents a significant obstacle for its successful rearing. It have been proved that a salinity of 10 psu is necessary for seed production during the first 10 days (Senoo et al. 2008). However, it remains unknown the effects of salinity on egg development and hatching success.The objective of this study was to study egg development, hatching and deformation rates under different salinities (FW, 5, 0, 15, 20 and 30 psu).
