Ogami scientific name Omi Oyster is an important economic shellfish cultured on a shallow beach. The conventional farming methods of Dayu are mainly divided into the types of beach planting, squat type hanging cultivation, and scaffolding culture. In the past two years, Liaozhou Town, Hepu County, has developed a method of large-scale deep-water pile pile-up. In 1999, the town introduced 6 million yuan of funds, and Daxie deep-water piles raised the area of ​​620 acres, 46 households, and obtained Significant economic benefits. Lin Zhijian, a farmer in Maan Village, Lianzhou Town, raised 6,500 wooden stakes and earned more than RMB 10 million. Most of the large-scale professional squatters have built buildings and equipped with mobile phones, BP machines, and home phones. Modern furniture is readily available. In order to adapt to the development of the market, adjust and optimize the structure of the sea culture, and promote the development of specialization of the sea-farming industry, the main points of its breeding techniques are introduced as follows for your reference.
I. Selection of pile-hanging sea areas: In the aquaculture sea area, the inner bay area with small waves, smooth water flow, fresh water injection, and rich bait is generally selected. The proportion of seawater is from 1.006 to 1.020, and the water depth is often maintained from 4 to 8 meters. Quality or mud is better.
Second, the production of hanging wood piles: wood piles available eucalyptus trees, piles 2 meters long, tail diameter 4 to 6 cm.
First, remove the mudflats that have been cultured on the beach and remove them from the concrete bar. The specifications are 8 to 10 cm long and 8 to 10 per kilogram. Then use a percussion drill to drill a hole in the top of each big clam shell, with an aperture of 6 mm. Then use a single strand of white plastic (diameter 3 mm) to string together the big quail, each weighing about 15 kilograms. Finally, the big gongs were strung together with stakes, iron nails and iron wire. The length of the big gongs was about 1.2 meters. After the big wooden poles are well prepared, they are ready for shipment in batches to the farm.
Third, the stakes: stakes method is to select the sea area when the tide of dry water, the first pile up, and then use high-pressure water gun spray hit the pile foot beach, wooden stakes slowly inserted. The stakes are inserted in silt of 50 to 60 cm and can resist the impact of the waves and prevent tilting or falling. The stake spacing is equal to the pile pitch, both 100100 centimeters, with 600 to 700 piles per acre. The arrangement direction of the stakes should follow the trend.
4. Routine management: Whenever the water ebbs, it is necessary to go to the farm for inspection. It is found that it is necessary to plug in positively due to the ship coming in contact with or impacting with the tide. In particular, before and after the typhoon, it is necessary to take care of the sudden assault in the sea so as not to overwhelm the mud. Suffocate death. Each farm needs to build a sea shed for conservation, with special care, which is conducive to aquaculture management.
V. Harvesting and Benefits: Daegu wooden piles are raised and maintained from May to June, and can be harvested for 6 to 8 months. The harvesting method is to use low-pressure water jets to spray the water and hit the feet and sand, and the wooden stakes can be pulled out, concentrated on the ship and transported to the shore to harvest meat. The large-scale slugs grown in the deep water of the stakes grow fast, have a delicious plump meat, and have a high meat yield. At the time of harvest, the size of the oysters is 3 to 4 per kilogram, the ratio of quail to meat is 6.5:1, the shelled oysters are sold at the price of 2.2 to 2.6 yuan per kilogram, the quail meat is sold at the price of 19 to 21 yuan per kilogram, and the average yield per mu is large.èš Up to 13 to 22 tons,
The average profit of each stake can reach 25 to 35 yuan. Daxie deep-water wooden pile hanging is a new breeding method with considerable economic benefits. It is suitable for promotion and use in the Guangxi coast.
