南昌县岗上乡有零星池塘近200口,养殖水面为2083.5亩,1978～1983年六年中,平均亩产45.5公斤。而我国池塘养殖面积为1604万亩,1985年亩产92.5公斤,相差47.0公斤,但仍属于低产水平。 1984年南昌市科委将大面积零星池塘养鱼技术列为开发研究项目,由县畜牧水产局具体负责实施,要求1984年亩平100公斤,1985年200公斤,1986年300公斤。经过三年实验,1984年经市、县验收亩产为134.8公斤,1985年亩平223.9公斤,1986年亩平321.10公斤。均超过原计划指标,并比我国1985年池塘单产高出2～3倍。现总结报告如下:
There are sporadic ponds in Gangchang County, Nanchang County, nearly 200 mouth, breeding water surface of 2083.5 acres, 1978 ~ 1983 six years, the average yield 45.5 kg. The pond aquaculture area in China is 16040000 acres, 92.5 kilograms per mu in 1985, a difference of 47.0 kilograms, but still belong to the low yield level. 1984 Nanchang Science and Technology Commission will be a large area of sporadic pond fish farming technology as a research project, the county Livestock and Fisheries Bureau specifically responsible for the implementation of the requirements in 1984 acres of flat 100 kg, 1985, 200 kg, 1986, 300 kg. After three years of experiment, in 1984, the counties and counties inspected and produced 134.8 kilograms per mu, 223.9 kilograms per mu in 1985 and 321.10 kilograms in 1986. All surpassed the original plan index and was 2 ~ 3 times higher than our country’s 1985 pond yield. The report is summarized as follows:
