The effect of salinity on the growth and muscle nutritional quality of the Exopalaemon carinicauda was studied through testing the survival rate, specific growth rate, muscle nutrient composition, amino acid composition and content by the culturing in different salinities(0-30).The results showed that the survival rate of salinity (0-30) had no significant difference (P>0.05), and the specific growth rates at salinity 15 and salinity 20 were significantly higher than others(P>0.05); the muscle moisture content and the crude fat content significantly decreased(P<0.05), while the muscle crude protein content significantly increased with an increase in the environment salinity from 0 to 30(P <0.05).The crude ash content with salinity increase had a slight increase; the muscle crude protein content (18.2) at salinity 15 was significantly higher than that at salinity 0,5, or 10(P <0.05), but there was no significant difference between salinity 15 and salinity 20(P>0.05). No significant difference was found in total amino acid content or total essential amino acid content from salinity 0 to 30(P>0.05). Total delicious amino acid content at salinity 15-30 was significantly higher than those at salinity 0-10 (P<0.05), while there was no significant difference from salinity 15 to 30(P>0.05). The results suggest that the suitable salinity for muscle nutritive value ranges from 15 to 30, and the Exopalaemon carinicauda can potentially be cultured above the salinity 15.Journal
