六、七月间,我场要运出大批鲢、鲷、草、鲂等夏花鱼种。运输方法,除活水船外,公路汽车运输用帆布袋娄子(长、宽各80厘米,高100厘米),运输时装水约800市斤,一辆三吨车可装6～8个。其运输密度,每升水一般只装鱼:0.7市寸,62尾;1.0市寸,50尾;1.2市寸,38尾。由于天气热,水温高达31℃以上,一般成活率约80%,运输率很低。为了提高运输率和成活率,我们遵照毛主席“抓革命,促生产”的教导,根据小型尼龙袋运输鱼苗种的经验,试验成功了大型聚氯乙烯薄膜袋(长、宽各85厘米,高200厘米)充氧密封运输夏花鱼种,成活率一
Between June and July, my field will transport a large number of summer flowers such as silver carp, snapper, grass, and chrysanthemum. Transport methods, in addition to living water ships, road transport vehicles with canvas bag Louzi (length, width 80 cm, height 100 cm), transport fashion water about 800 jin, a three-ton car can hold 6 to 8. Its transport density, per liter of water is generally only installed fish: 0.7 City inch, 62; 1.0 City inch, 50; 1.2 City inch, 38 tail. Due to the hot weather, the water temperature is as high as 31 ℃, the general survival rate of about 80%, the transport rate is very low. In order to improve the transport rate and survival rate, we follow the Chairman Mao’s guide to “grasp the revolution, promote production”, according to the experience of small-size nylon bags to transport fish species, the successful trial of large PVC film bags (length and width of 85 cm, 200 cm) Oxygen sealed summer flower transport, survival rate of a
