中国海域已报道的约90种对虾中,半数具有经济价值。其中中国对虾、墨吉对虾和长毛对虾无论在捕捞还是在养殖业上都具有十分重要的地位。由于3种虾的形态非常相近,特别是在早期生活史阶段,它们的幼体和仔虾很难区分,因而给对虾种群补充、预报和其它有关研究造成困难。尤其在热带海域,对虾生殖季节重叠,幼体和仔虾的鉴别更加重要,各期仔虾的数量统计需以严格的形态鉴别作为依据。作者对三种对虾的幼体的形态,区别已有专文报道(Liu and Liu,1994)。本文深入细致地研究了中国对虾、墨吉对虾和长毛对虾仔虾的发育形态学,并进行了比较,使3种对虾的仔虾得以区别,并为今后的对虾生态学研究及资源管理奠定基础,提供依据。
Of the approximately 90 species of shrimp reported in the seas of China, half have economic value. Among them, shrimp, shrimp and shrimp Penaeus chinensis have a very important position both in fishing and in aquaculture. Due to the very similar morphology of the three shrimp species, larvae and larvae are indistinguishable, especially during the early life stage, resulting in difficulties in supplementing, predicting and other studies of shrimp stocks. Especially in tropical waters, shrimp reproductive season overlap, larvae and larvae identification more important, the number of larvae of each stage statistics need to be based on strict morphological identification. The author of the three shrimp larvae morphology, the difference has been reported in the article (Liu and Liu, 1994). In this paper, the developmental morphology of Penaeus chinensis, Megagrady shrimp and Penaeus chinensis were studied thoroughly and meticulously, compared with that of Penaeus chinensis, and laid the foundation for future research on shrimp ecology and resource management Basis, provide basis.
