在水温26～28℃,pH8.1～8.3,海水盐度27.6～29.7的条件下,刀额新对虾幼体从无节幼体第一期(N_1)培育至仔虾幼体第一期(P_1),历时10d,成活率81.9%;至仔虾幼体第8～10天(P_(8～10)),成活率为80%。刀额新对虾幼体发育具有许多不同于其他对虾类幼体的发育特点,其糠虾期身体仅稍倾斜而不呈倒悬状态,极少摄食丰年虫无节幼体,直至P_(3～4)摄食丰年虫幼体现象才较多见。 Under the condition of water temperature of 26-28 ℃, pH8.1 ~ 8.3 and seawater salinity of 27.6 ~ 29.7, the larvae of Penaeus chinensis grew from the first stage (N_1) of nauplii to the first stage (P_1) of larval larvae, The survival rate was 81.9% after 10 days, and the survival rate was 80% after 8 to 10 days of larval larvae (P_ (8 ~ 10)). The development of juvenile Penaeus vannamei larvae was different from that of other shrimp larvae. The body of the shrimp was slightly tilted but not upside down, and fed on Artemia nauplii very rarely until P_ (3-4) Larvae phenomenon more common.
