摘要
报道在珠海万山海洋开发区小蜘洲岛细洲湾进行的海洋经济鱼类和贝类的不同混合养殖模式的实验研究,通过比较各项水质指标,分析了不同养殖模式对水体环境状态的影响。结果表明:单养和混养养殖模式都导致水体富营养化,单品种养殖比鱼贝混养的引起的富营养化程度更为明显。不是随意的鱼类和贝类混养都可以达到好的生态效益,只有在大量可靠的基础研究的基础上,科学组合混养,才能达到好的生态和经济效益。
The purpose of this research is to study the environmental effects of different culture models of the economical fishes and shellfishes in order to establish the best combination of different kind of polycuhure. The results showed that any kind of pen aquaculture would accelerate the eutrophication and water quality deterioration. To a certain degree the influence of single-species culture of fish on water quality will be more serious than fish polyculture. This study also indicated that not random combination of fishes and shellfishes could get good environmental effect. Only if they were cultured in mixture scientifically, could it attain a good environmental as well as economic benefit.
