中文摘要:
      一、前言 锯绿青蟹,简称青蟹,俗名“红”,属甲壳纲十足目游泳蟹科。我国的浙江、福建、台湾、广东诸省沿海均有分布,尤以广东、福建为最多,在国外的分布有日本、菲律滨、越南、印度等国。其肌肉和生殖腺,富有营养价值,且味道可口,素为我国人民所爱好的食用蟹,又是重要的出口的水产品之一。故其在水产经济上占有相当重要的地位。 青蟹在菲律滨已广泛地与遮目鱼Chanos chanos(Forskal)共养于咸淡水的鱼池中。在我国的养殖已有70余年的历史,目前已成为重要的养殖对象。劳动人民经过数十年的生产实践,至今积累了许多宝贵的经验。
英文摘要:
      1. Scylla Serrata (Forsk?l) has been successfully reared from the first zoealstage to the tenth crab stage in the laboratory, and all the larval stages aredescribed in detail. 2. Eggs hatched as first zoeae; and the "pre-zoea" stage was not observed. 3. Five zoeal stages and one megalop stage were observed in the completedevelopment to the first crab. 4. The number of hairs or spines on the maxillule, maxilla and maxillipedsincreased with each larval stage and may serve to distinguish between the zoeaeof different stages. 5. Development from the first zoeae to the first crabs required 23-24 daysat temperatures 25. 7-29.2℃. 6. Development from the first young crab stage to the tenth young crabstage required 123 days at temperatures 18.0-31.5℃. 7. In the first three young crab stages, moulting took place every 4 days;in the five subsequent stages, the time between two successive moultings length-ened from 5 to 12 days; and in both the ninth and the tenth stages, the timewas as long as 30 odd days. 8. The growth intensity of the crab diminished with age.
