The growth characteristics of a brackish-water calanoid copepod Sinocalanus tenellus (Kikuchi) were investigated in relation to temperature and salinity. Egg hatching and postembryonic development were successful over a wide range of temperature (6.6-31.3°C and 6.2-27.1°C, respectively) and salinity (2.5-35.0 ‰ and 5.0-30.0 ‰, respectively). The time required after egg-laying to reach any developmental stage increased with the decrease of temperature. The effect of salinity on the development time was not so marked as that of temperature. The stage duration was shortest in NI, nearly constant from NII to CIII, and somewhat prolonged in CIV and CV. Males developed faster than females. Body length of S. tenellus decreased with increasing temperature for each developmental stage except for NI. Salinity did not appear to affect the body size significantly except for CV and CVI, where the size became largest at 15 ‰. The daily specific growth rate increased exponentially with increasing temperature, and was highest at a salinity of 15 ‰. The present study indicates that S. tenellus is a eurythermal and euryhaline copepod with a high growth potential.
