摘　　要：重庆境内河流属长江水系，以长江、嘉陵江、涪江等河流为骨干和主体，水域面积８．２５万ｈａ，占水域总面积的７６．４％。船体网箱养鱼是近年来在该地区兴起并迅速发展的鱼类集约化养殖方式。本文根据船体网箱养鲤试验结果和有关资料，分析了重庆境内江河水温、含氧量、流速、含沙量、浮渣、工业污染特点及对船体网箱养鱼的影响，拟合了养殖舱内、外流速关系及含沙量与透明度关系，并就船体网箱养鱼的进一步发展提出了措施。Jialijiang River and Fujiang River in Chongqing are major branches of Yangtze River.Their total area about 82 500ha,about 76.4%,Cases of vessels is a new method.It fjrstemerged over there and developed very fast.In this paper,the characters of watertemperature,oxggen content,flowing speed,silt content,float residue and industry pollutionand their affect on culturing carp in net cases of vessels were studied by our experimentresults and relative imformation. The relation of the silt content between outside and insideof the vessels and that between silt content and tranparency were calculated.Theconstructive suggestions for further development of this culturing method were alsopresented in the paper.
