摘要
采用定点多次重复取样的方法对我国南方地区的茂名市水东湾网箱养鱼及龙山镇养虾场的盐度、悬浮物、Cr6+水质进行了检测。结果表明:茂名水东湾网箱养鱼及龙山镇养虾场的盐度变化于18.4～26.9%之间;悬浮物在3～7mg L之间;Cr6+含量变幅于0.0024～0.0049mg L之间。该区域水质多在渔业用水标准规定的适宜范围内,说明茂名市近海水东湾及龙山镇养虾场水质总体良好,渔业无公害生产开发潜力较大。
According to the present situation of disease problems in seawater fishery of Maoming onshore, including Shuidong gulf netting fishery and Longshan fishery, we monitored the contents of the salts, SS and Cr^(6+) of Seawater with the method of timing sampling analysis at different places. The result shows as following: In all places, the salt contents are between 18.4～26.9‰ for all samples, the SS contents between 3 ～7mg/L, and the Cr^(6+) contents varied 0.0024 ～0.0049mg/L .Compared to the national seawater quality stipulations, these indicators are basically reached the good national stipulation of the seawater. All of these especially told us that the harmful material in seawater in some places had no seriously effected the development of fishery for Maoming onshore. The great potent ional of fishery production has been made in these areas.
