The effect of salinity on the growth and muscle nutritional quality of theExopalaemon carinicauda was studied through testing the survival rate, specific growthrate, muscle nutrient composition, amino acid composition and content by the culturingin 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 andsalinity 20 were significantly higher than others(P>0.05); the muscle moisture contentand the crude fat content significantly decreased(P<0.05), while the muscle crudeprotein content significantly increased with an increase in the environment salinity from0 to 30(P <0.05).The crude ash content with salinity increase had a slight increase; themuscle crude protein content (18.2) at salinity 15 was significantly higher than that atsalinity 0,5, or 10(P <0.05), but there was no significant difference between salinity 15and salinity 20(P>0.05). No significant difference was found in total amino acid contentor total essential amino acid content from salinity 0 to 30(P>0.05). Total delicious aminoacid 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). Theresults 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. 展开更多
