广西大化岩滩库区网箱养殖容量分析

【目的】估算出广西大化岩滩库区的网箱养殖容量,为大化岩滩库区渔业开发规划的编制和实施提供理论依据。【方法】2010年3月~2011年7月,对大化岩滩库区的11个位点进行取样调查,通过分析水体氮、磷含量确定水体营养物的限制性因子,并通过构建库区网箱养殖承载力模型估算大化岩滩库区的网箱养殖容量。【结果】磷为水体营养物的限制因子,广西大化岩滩库区水体磷承载力为528t,网箱养殖罗非鱼和斑点叉尾鮰的最大鱼产力分别为32393和23250t,对应的网箱养殖面积分别为431907和33214m2,水库网箱养殖承载力分别为6.7‰和5.2‰。【结论】广西大化岩滩库区养殖容量较大,适宜开展水库投饵网箱养殖,但...

Objective This research estimated the cage culture capacity of Guangxi Dahua Yantan reservoir in order to provide theoretical bases for elaborating the developmental plan of Yantan reservoir fishery.Method From March 2010 to July 2011,11 sampling spots from the Dahua Yantan reservoir were investigated and relevant samples were collected through the analysis of the corresponding nutrient limiting factors,including nitrogen content and phosphorus content.The reservoir cage culture carrying capacity model was built on the basis of the Dillon-Rigler model for estimating the ca
