摘要
对大连沿海口虾蛄Oratosquilla oratoria在人工培育条件下幼体的发育过程及形态特征进行了观察。结果表明:在水温为23—26℃、盐度为36的条件下,口虾蛄从Z1期假蚤状幼体开始,历时33d出现第1期仔虾;大连沿海口虾蛄Z1期假蚤状幼体第2触角羽状刚毛数、Z4期假蚤状幼体第2触角羽状刚毛数及尾节侧小齿、中间小齿、亚中间小齿数及头胸甲长与日本口虾蛄存在差异。
In the present paper, the morphological development of larval mantis shrimp Oratosquilla oratoria was described under experimental condition in Liaoning province, China. The Zoea 1 pseudozoea was found to develop into young squilla in 33 days at a water temperature of 23 - 26 ℃ and a salinity of 36. The morphological characteristics of each developmental stage were particularly recorded and described and apparent differences were observed in the number of plumose seta on the second antenna at Z1 and Z4 pseudozoea stages,as well as the number of side,middle and sub- middle protuberances on the telson, and the carapace length between the mantis shrimp in Liaoning province and mantis shrimp in Japan reported by Hamano.
