中华绒螯蟹,通常称河蟹。其肉味鲜美,营养丰富,适应性强,养殖成本低,经济价值高。为了增殖我省水产资源,扩大养殖品种,充分利用滇池的饵料基础,我们于1980年6月进行了河蟹大眼幼体(即蟹苗)的引运工作,由上海崇明县北四激闸口接苗,空运昆明投放滇池。通过一年的试养已取得初步成效,现将工作情况报告于下: 一、运输我们是1980年6月14日上午10时接苗的,共27公斤,6月15日8时运至上海虹桥飞机场,再次检查、转箱、捆扎托运。于中午12时45分起飞,下午6时抵昆,8时左右投放完毕。从接苗到投放历经36小时,投放时成活率70%,总成活率为60%。据我们分析,成活率低的原因,是由于轮船脱班,当天天气炎热,蟹苗长时间堆放在码
Chinese mitten crab, commonly known as crab. Its delicious meat, nutritious, adaptable, low cost of breeding, high economic value. In order to multiply the aquatic resources in our province, expand the breeding varieties and make full use of the bait foundation in Dianchi Lake, we carried out the transference and transportation of Euglena gracilis larvae (crabs) in June 1980. From Chongkou County, , Kunming air delivery Dianchi Lake. After a year trial, preliminary results have been achieved. Now we report the work under the following conditions: I. Transportation We pick up the seedlings at 10:00 on June 14, 1980, a total of 27 kilograms, shipped to Shanghai Hongqiao at 8:00 on June 15 Airport, check again, transfer boxes, tied consignment. It took off at 12:45 p.m. and arrived at Kunlun at 6 p.m., and was put on at about 8 o’clock. From pickling to delivery after 36 hours, when put into operation, the survival rate of 70%, the total survival rate of 60%. According to our analysis, the reason for the low survival rate is due to the ship going off work, the weather was hot and the crabs were piled up for a long time
