【摘要】 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（N₁）培育至仔虾幼体第一期（P₁）,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。更多还原

【Abstract】 In sea water of 26～28℃, salinities 27.2～29.7 and pH8.1～8.3, it rates about 10d from naupilaf stage 1 （N₁） to postlarval stage 1 （P₁）, with a survival rate of 81.9%. A survival rate of 80% was obtained from naupliar stage 1 （N₁） to postlarval stages 8～10 (P_8～10). It is found that some characteristics of larval development in this species differ from those in other species of Penaeus. At mysis stage, they make their bodies only inclining a little without falling heads over tails, and feed seldom on Artemia sp. nauplius larve.更多还原
