Radiator Valve No matter how the capture of the Oriental River Prawn, should not brass ball valve dehydration. Will be long-distance transportation of goods used for shrimp farming and small shrimp-out specifications, in the custody or running water Chuancang box-net box. At present, the production of commonly used box-cage Zanyanghuoxia. This network can be worried about me on both sides of the shrimp boat or after the shoot. Offshore fishing boats arrived, the speed of goods will be transported shrimp Tun custody, juvenile sent to a nearby pond for breeding.      The big catch shrimp commodity specifications for various reasons can not be occasional shipment, the road network must support me Tun. General produced a number of pre-2.5 m, width 1.5 m, high 1 m nylon small cage, the cage will be placed in dissolved oxygen rich water clean water per mouth cage Tun custody of not more than 25 kg. Tun custody can be properly fed during the Qiaosui Lo, moths, mussels and other animal feed. Large Macrobrachium nipponense Tun custody should not be too long a time, the longer the higher mortality rate. Because when the water temperature at 15 above, it is likely that some of Macrobrachium nipponense Tun custody during molting, while Cage in Macrobrachium nipponense density is too large, no hidden places, so easy on the molting process of death or other residue fresh shrimp Swaps.      In addition, high-density Tun Macrobrachium nipponense physical custody will cause the drop-off, physical wear and tear, may be a large number died in transit, so long-distance transportation to the general Macrobrachium nipponense custody for too long can not tun ,1-2 d FOB, the survival rate The highest.      1.3 Sorting      Macrobrachium nipponense FOB to be sorted according to size specifications, packaging. Sorting Macrobrachium nipponense should be in the Oval Su Liaopen Mupen or conducted within the pelvic floor drilling a few holes, neither water basin, we can not have stagnant water. Add to Macrobrachium nipponense, the flow of water to go. Sorting Macrobrachium nipponense to avoid strong light or strong winds, to prevent their brass ball valve gills in water or in the glare of the rapid evaporation and strong winds caused the death. Sorting should be done in the shortest possible time.      3 mm of water tanks by welding a steel plate. Water tanks around the outside of the upper, middle and bottom with 3 cmx3cm welding angle steel reinforcement of the framework. And all four sides with two 3 cmx3cm vertical angle steel welding reinforced, Xiang Tinei Antirust Paint the outside painted. Can also use cedar board structure made of wooden water tanks. Even in high-temperature season in the box on a package of plastic foam insulation, then a layer of aluminum skin package, the upper tanks covered by 6 cm in diameter of the ball valve brass ball valve welding two sides in the lower part of a drainage tank valve. Water tanks in the other end of the lower left side of a diameter of 3.5 cm of the hole, through the inlet pipe used.  brass ball valve
