dc.description.abstractTo explore the optimal growth and reproduction temperature of <em>Exopalaemon carinicauda</em>, this study tested five temperature gradients (16℃, 20℃, 24℃, 28℃, 32℃) to determine the effects of different temperatures on the growth, digestive enzyme activity, ovarian development performance, ovarian nutrient concentration, vitellogenin, and sex hormone levels of <em>E. carinicauda</em>. The results showed that (1) Between 20℃ and 32℃, the survival rate gradually decreased with the increase of temperature. As the temperature increases, the final body weight and specific growth rate first increase and then decrease (P\<0.05), with the fastest growth at 28℃; (2) The lipase activity first increases and then decreases with the increase of temperature (P\<0.05), reaching a maximum value of 1.22 ± 0.09 U/gprot at 28℃. The trypsin activity increased with the increase of temperature and reached a maximum value of 1695.45 ± 163.42 U/gprot at 32℃; (3) the gonadosomatic index and ovarian maturation rate increased with increasing temperature; the concentrations of total protein, total cholesterol, and triglycerides generally increased with temperature; the vitellogenin showed a trend of first increasing, then decreasing, and then increasing with the increase of temperature (P\<0.05); and (4) at temperatures of 24℃ and 28℃, the concentrations of gonadotropin-releasing hormone were relatively high and close. The highest estradiol concentration was 26.62 ± 1.49 ng/L at temperatures of 28℃. These findings indicate that 28℃ is a suitable temperature for promoting the maturation of the parent shrimp of <em>E. carinicauda</em> and may be recommended for a commercialized culture of this species.
