Effects of temperature on embryonic and larval development of the Exopalaemon carinicauda (Holthuis)
摘要
Abstract
To understand the reproductive biology of Exopalaemon carinicauda, the effects of temperature on em-bryonic and larval development of this species were evaluated using fertilized eggs and new-hatching larvae as ex-perimental materials. The results showed that the hatching time (TH) and hatching rate (RH) were significantly af-fected by temperature (P<0.05). The embryonic development was accelerated with the temperature increasing within the experimental temperature range (19~31℃). For example, the TH at 19℃ was (536.50±18.33) h post spawning, while it was only (218.68±5.51) h at 31℃. The highest (64.11%±12.54%) and lowest (14.79%±5.17%) RH values were obtained at 25℃and 19℃, respectively. Temperature also significantly influenced the larval devel-opment (P<0.05). At temperature range from 16 to 32℃, the duration of larval development (DLD) from mysisⅠ(M1) to postlarvae stage (P1) and the body length (BL) of P1 stage both decreased with increased temperatures, while the daily growth of body length increased with increased temperatures. DLD shortened from (27.60±0.22) d at 16℃ to (7.75±0.07) d at 32℃. The highest survival rate from M1 to P1 ( 1 1M ~PSR ) was gained at 28℃(91.67%±7.64%), while larvae failed to develop to P1 stage at 36℃. The optimum temperature of embryonic and larval development of E. carinicauda is 25.33℃and 27.60℃, respectively as estimated from the correlation equa-tions. The results in the present study could be used to facilitate the artificial seeding of E. carinicauda.关键词
