(2) Pick up the barrel. The fish farmers use buckets to transport the fish species. The barrels can hold about 3/4 of the water, and they can carry 80,000 to 100,000 fish fry or 10,000 to 1.9 to 2.0 centimeters long; or 3.3 to 5 centimeters of dried species of 4000 to 5000 fish; or 6 to 8 centimeters of fish to 600 to 700 tails; or 9 to 11.5 centimeters of fish to 400 to 500 tails; or 13 to 16 centimeters of fish to 200 to 300 tails. However, due to different local conditions, such as the temperature of the water, the weather is good or bad, the quality of the seeds, and the transport distance and other factors, the density of the shipment must be flexible because of the time.
(3) transport fish with a canvas bucket. At present, the types of canvas barrels used throughout the country are cylindrical and square cylinders. The commonly used specifications are a drum with a height and diameter of about 95 cm, or a square drum with a height, length and width of about 90 cm. There are protective covers around the upper mouth or on all sides to prevent water and seed from spilling out. Canvas bucket and iron frame and wooden frame support, can be disassembled and folded, easy to carry. Each canvas bucket can hold 400-450 kg of water, accounting for 60-70% of the entire container; in the case of 15-25, it can generally transport 300,000-400,000 fry; or 3-5 thousand summer flowers; or 6.6 centimeters 1 to 15,000 fingerlings; 5000 to 6000 tails for 9.9 centimeters; or 300 to 500 tails for 13 centimeters. In a 4-ton car, generally, six cap buckets can be placed. If a large plastic bag of the same size is provided in the bucket and the oxygen bottle is oxygenated, the amount of transportation can be greatly improved.
(4) Oxygen bags transport oxygen. This is a method of transporting the fish into a nylon bag and then oxygenating it. Nylon bags are small in size, flexible and maneuverable, easy to stack and manage, have high transportation density and high survival rate, and are commonly used as transportation methods by AOpen. Nylon bags are generally about 70-80 cm long and about 40 cm wide. There are packaging cartons used outside. Each nylon bag can contain 5-10 million fry; or 1-15 thousand tails of Wu Zai; or 30-50 million tail flowers; or 200-300 tails of 10 cm species. Check the bags beforehand to check whether there are holes and holes in the nylon bags. Then put in about a third of the water. Use a funnel to pour the fish or fish into the bag. Extend the air in the bag from bottom to top with both hands. , And then oxygen, until the nylon bag bulge, light pressure can be a depression, and then tie the bag mouth, folded back and then tightened. Nylon bags should not be placed on hard rough or grit areas to avoid punctures. Tie the nylon to lay flat in the carton, being careful not to stick to the tip of the inner wall of the carton. Nylon bags can be transported for up to 30 hours. It is necessary to reduce the number of stays and time during transportation. When staying, stop in a cool, ventilated place. Do not expose it to the sun. The temperature of the broodstock transported to transport the broodstock is best between 10-15. If the temperature is too low, the fish body is susceptible to frostbite; if the water temperature is too high, the fish is active and is easily bruised. The broodstock transport tools are mainly canvas buckets and nylon bags. The effect of a live water boat is also very good.
(5) Canvas transport. Suitable for short-distance transportation. Each canvas bucket can hold 400-500 kilograms of water, and can hold 1-3 kilograms of pro-carp 30--40 tails. The canvas bucket is best lined with nets to prevent bruising and easy fishing. It is even better if the canvas bucket can be oxygenated or inflated.
(6) nylon bag transport. Suitable for long-distance transportation. Each nylon bag can hold 2 to 4 tails. In order to prevent the hard spines of squid from piercing the nylon bag and causing air leaks and even death, hard buckthorn can be cut off or hard burrs can be trapped with a hose. Nylon bags should be thick and strong. When carrying, move it gently and gently, and minimize fish movements.

(1) Selection of fry and fingerlings. When buying fry and fingerlings, care should be taken to select good breeds with pure varieties, robust physique, neat specifications, lively swimming, strong water-repellent ability, and no damage. Before the transportation, it must be done by pulling nets to make it strong, eliminate body excrement, and adapt to the intensive environment. Floating on the water, traveling alone, and sluggish sluggishness are not suitable for long-distance transportation. Dead fish should be cleared in time.
