ANOVA results showed not only that both temperature and salinity have significant effects on survival for all larval stages (Table 1), but also their interaction. Overall the result of analysis of variance for mortality was a fully significant matrix for larval stages, factors and their interaction.
Contour analysis defines clear centres of optimal combinations of temperature and salinity for the survival of Parasesarma catenata larval stages (Fig. 4). The optimal points of salinity are close to full salinity seawater, and temperature is within the expected normal range for summer condition in the area (20 to 27 ºC).
