1. Pond preparation: Each pond has a small area of ​​1.5 acres, a large 20 acres, generally 7 to 8 acres is good, too inconvenient to manage, and difficult to vote a full seedlings, too small is not conducive to the growth of shellfish perched, affecting the yield The improvement. The pond embankment does not have to be as tall as a shrimp pond, and is generally 50-60 cm. The bottom of the pond should be higher than the low tide line, and should be flattened so that the benthic diatoms can be fertilized and sun dried. The bottom soft clay is preferred, and the bottom is a muddy oil surface, which is conducive to the propagation of algae and algae. In the pond, a cross ditch or Tianzigou is dug, and the depth of the ditch is 30 to 40cm. The width of the ditch depends on the area. It is generally set at 2m and connected with the gate to facilitate drainage. Each pond is provided with one entrance and one drainage gate, and the depth of influent at the time of high tide does not exceed 30cm. A fence is added to prevent escape and the invasion of predators. Bomb coated fish mainly feed benthic diatoms, followed by blue-green algae, only algae grow well, in order to make the mud-coated fish grow well. Therefore, before releasing the seedlings, do a good job of drying up the bottom of the pond, apply base fertilizers, eliminate predators, and disinfect clear ponds. Ordinary organic matter is more old shrimp pond, sun to crack after the cast rice bran, water injection 5 ~ 10cm can be stocked, the new pond per acre chicken, pig manure and rice bran about 40kg, water depth 2 ~ 7cm is appropriate. 2, seed stocking: This article has said in the opening paragraph, the current artificial breeding of Xu fish breeding seed is still in the laboratory stage, can not provide the amount of seedlings for production. From the above tests, artificial breeding, breeding of juvenile fish after 50 days of age can be put into pond breeding, but at present, large-scale breeding still captures natural seedlings. Harvested or acquired without injuries, seedlings with a body length of 5 to 10 cm are cultured in the pond and grow fastest, with a slow growth of more than 30 cm. Therefore, it is generally 400-500 tail/Kg in the pond size, and 3000-6000 tails per acre. It is also believed that 2,000 to 3,500 tails/mu are good, and the center of gravity is too high. The supply of algae in the pond is not on the contrary, but it will affect growth. Due to the phenomenon of no mutual disability of mudskipper fish, the seedlings can be seeded in batches in the same pond, thus solving the problem of insufficient acquisition or harvesting. General breeding survival rate of up to 80 ~ 90%. 3, daily management: Feeding problem one - the major cable fish Tuoba algae, do not directly feed rice bran, bean cake, peanut cake and other feed. Therefore, there is no need to feed bait when breeding, as long as the benthic algae can be cultivated well before transplanting. After feeding for a period of time, the benthic diatoms disappeared and the water quality was turbid. They must be drained, sun bathed, and fertilized to promote the reproduction of benthic diatoms. The seedlings in the initial stage of seedlings are not deep enough to drill holes, so the water depth is maintained at about 15cm, and the water depth at the ditch is about 30cm, which is too large for the temperature change of water, which affects the growth. After about 49 days of breeding, if you grow to more than 5cm, you can drill deeper holes. At this time, if benthic diatoms disappear or decrease, optional sunny, drain off the pond water, leaving only some water in the ditch, cracking after 3-6 days of the sun, that is, fertilizer water, rice bran, generally 20kg per mu. In order to evenly and thoroughly apply the soft and wet water at the bottom of the pond, the rice bran should be wetted and adhered to the pond mud, and then dried to cracks. The seawater should be injected in about 3 to 10 cm, and the diatoms will continue to multiply in a few days. When manure or fertilizer is applied, do not allow a large amount of manure to directly flow into the tunnel and kill the smeared fish. Apply it to the surface of the cracked soil, or mix and dilute it with the influent water. This will not irritate the mudskipper in the hole. In this way, during the cultivation, it is repeatedly operated to ensure that there are enough benthic diatoms for feeding fish. Insulation problem - In order to improve the pond temperature in winter, selenium ponds must be drained when there is no wind and waves, and more water should be used to insulate water when it is cloudy and cold. When the water temperature drops below 14°C, the mudflater has burrowed. Free food. Harm to the problem - 1 Fish harm: Fishes such as sea otters and sand plague will prey on the seedlings of the bombardment fish. Each time they enter the water, they should be blocked to prevent them from invading the pond. 2 Bird Harm: General use of drive or police to drive away birds. 3 Crab damage: Small crabs will invade predator fish in the smear-coated fish hole, or they may be caught in the crab hole and be eaten and eaten too. Therefore, plastic plates shall be used around the pond to prevent crabs from intruding, and light may be used to kill the fish in the pond at night. Small crab. 4 other harm: such as conch, hairy species do not directly harm the mudskipper fish, but compete with eel and fish to eat diatoms, but also try to drive it out. 4. When the size of the transported bombardment fish is 50/kg, it can be listed on the market, but it will be difficult to catch the fish as soon as it is disturbed by the police. The special capture method is described as follows: Harvesting - 1 cage trapping: Drain the pond water, leaving only the ditch water, and then look for entrances and exits with traces of traces, no traces of the rear exit, plugged with mud, and then exit. Then insert the fish cage mouth into the entrance and exit, and make a mark. The smear-coated fish can only enter the cage from the unsealed import, and harvest it once every other half, and then change the new orifice. (2) The method of hanging net: Using the back-drawing habit of mudskipper fish, drain the pond water first or leave a few centimeters, and then set a hanging net at the water inlet, use the high tide to slowly enter the water, and pull the water to catch the fish in the hanging net. Captured on the net, each high tide can be operated 3-5 times. In the case of 2 cases, the method of setting up the net: also using its retrogressive habits, when the inverted net bag is installed at the gate, when the tide is flooded, the backwater enters the inverted net and is captured. 4 hand-shouldered net method: eel-bearing fry 1-3cm fashion without drilling cave home capacity, often habitat in the mudflat shallow water rafts, or clusters in shallow mangrove water rafts, hand dip net fishing. Only suitable for seedlings. Transport - Bullet-bearing fish transport is simple, as long as maintain a suitable temperature, add a small amount of water, long-distance transport. The fishmonger used a circular sieve tray with a diameter of 80cm and a depth of 20cm. The bottom of the sieve tray was covered with a plastic film. The membrane edge was higher than the bottom of the tray and stuck to the sieve tray wall. The fish was put into the mudball and a small amount of water was added. Several sieve trays were stacked. In the passenger station to carry baggage transport, transport survival rate of 2-3 days 100%.
