为了探索盐碱地“上粮下渔”开发池塘综合利用的路子,2004年,我们进行了淡水鲨与南美白对虾池塘半咸水混养试验,经过124天养殖,淡水鲨平均规格达1.2kg/尾,平均每667m~2产量343.6kg;南美白对虾平均规格达12.6cm,平均每667m~2产量67.2kg。每667m~2综合效益4139.6元。现报告如下:1材料与方法1.1养殖池塘试验池塘为利津县汀罗镇毛坨村2003年秋季新开发的“上粮下渔”池塘,有效养殖水面为1667m~2(2.5亩),池深2.5m,有效水深可保持2.0m,池底
In order to explore the way of comprehensive utilization of ponds in developing salinity-alkaline land, we carried out the experiment of mixed culture of freshwater sharks and Penaeus vannamei ponds in brackish water in 2004. After 124 days of breeding, average freshwater sharks reached 1.2kg / , An average of 343.6kg per 667m ~ 2 production; Penaeus vannamei average size of 12.6cm, an average of 67.2kg per 667m ~ 2 production. Each 667m ~ 2 comprehensive benefits 4139.6 yuan. The report is as follows: 1 Materials and methods 1.1 Breeding ponds The experimental ponds are the newly-launched “Shangyu Xiayu” pond newly developed in the autumn of 2003 in Mao Tuo Village, Tingluo Town, Lijin County. The effective aquaculture water surface is 1667m ~ 2 (2.5mu) 2.5m, the effective depth can be maintained 2.0m, bottom
