Three methods of broodstock transportation
First, the canvas box transport method depends on the canvas box volume and decides the quantity of transport. The general density is 100 kilograms of fish per cubic meter of water, and 2-3 cans of 3-5 ton trucks can contain 300-500 kilograms of fish. With this type of transport, it is better to transport within a short distance of 3-5 hours and it is not suitable for long-distance transportation. In order to avoid violent movement and bruising of the broodstock during transportation, each broodstock can be placed in a pre-made gauze bag and the tail bag tied. The width and length of the gauze bag should exceed the width and length of the broodstock so that the broodstock can move freely in the canvas case after being packed into the bag. Second, oxygenated sealed transport method (a) inside the fish tank filled with oxygen bag sealed in each fish transport a special, larger specifications of the plastic bag, fish and water in the bag accounted for 50% of the total - 75%. Each fish can hold 40-45 kilograms of broodstock, sealed with oxygen. This method can be changed in the middle of water, oxygen, easy operation, transport time up to 20 hours. (b) Plastic bags of water filled with oxygen sealed and transported one broodstock per bag, the water volume in the bag is greater than the lid of the fish, and the fish water accounts for 1/2 - 2/3 of the volume of the bag. The oxygen-sealed plastic bag should be placed in a suitable carton or wooden box. This method has a high transportation cost and is generally suitable for long-distance air transportation. (C) capsule bag oxygenation sealed transport each capsule bag (ie the current transport of fresh fish into the commonly used oxygen bag, the market for sale) can carry 15-20 kilograms of broodstock, fish and water ratio of 1:1, sealed with oxygen can be transported . Third, live water tank transport method This method of transport density is 200-250 kg of fish per cubic meter of water, transport time 10-12 hours. The main disadvantage is that when the aerobic machine is started, the broodstock jumps frequently in the water tank (especially the whitefish) and it easily collides with the inner wall of the tank and the roof, causing serious injury to the fish, affecting the survival rate and the introduction effect. It is not suitable for long-distance transportation.
