青蟹坛养与塘养对比试验

COMPARISON CULTURE TESTS OF THE MUD CRAB SCYLLA SERRATA (FORSKAL)IN SALTWATER POND AND IN CERAMIC ALTAR SUSPENDED IN BEACH

本试验采用φ２６ｃｍ、高２８ｃｍ的陶瓷坛子，进行了滩涂青蟹坛式养殖，并与塘养作对比试验，结论是坛养可行，四个月可养成商品蟹，苗种选５～６ｃｍ以上为好，滩位以大小潮都能满上、大潮落潮时每次能露水２小时左右为宜。坛养后期蜕壳较难，死亡率较高，还需改进。

Mud crab culture experiments were producted with ceramic altar(diam-eter 26 cm, height 28 cm)in comparison with saltwater pond culture. Theresult showed that ceramic altar culture is feasible.Commercial sized crabcan be obtained after 4 months rearing with larve of 6 cm in the zone whereboth spring and neap tide can flow to and the expose time is about 2 hoursin ebbing period of springtide . It occured a high mortality for crab to shedin the post period of ceramic altar culture, remaining further study toImprove.
