Beach embankment, block, catch up, eel conservation technology

Beach embankment block Grazing is a semi-environmental aquaculture method that uses a barn to raise loach in the upper part of the beach embankment. In recent years, it has developed rapidly in the suburbs of Xiamen, Fujian Province, and has also achieved remarkable results. The technical points are summarized as follows:
First, culture conditions and materials
1. Site selection: It is required to choose no pollution in the sea area, smooth flow, and flat terrain. Beaches that can avoid wind and waves, the area of ​​5 acres -15 acres, the bottom of the sludge to the main mud, the surface of the yellow floating mud 5cm-10cm better, the middle and lower layers of sediment, the proportion of seawater more than 5 inches, pH 7. 8-8.6.
2. Dam: The structure of the dam depends on the geological conditions. Generally, the embankment height is 1.5m, and the harder bottom is made of dry rubble. In the middle, more than lm of land fills the sea mud to be used as the breakwater layer and the bamboo sticks are used to hang the net; the bottom is softer. The bottom is ballasted with gravel.
3. Gates: The gates are mainly exposed on a regular basis to remove enemy enemies and harvests. In order to facilitate the operation, the gate should be higher than the water surface, and three gates should be provided.
4. Overflow port: The overflow port is set up to buffer the rise and fall tide, especially when the tide rises, the water level exceeds the inlet speed of the gate and the drop is too large to easily flush the embankment. The height difference between the overflow and the embankment is about 20cm, and the width depends on the area of ​​the pond. Generally, the width of the 5mu-15m overflow overflow is 5-10m. A semi-circular enclosure should be set up in the overflow to reduce the impact of water.
5. Blocking: In the middle of the dike, a bamboo pole is inserted every 2m, with a diameter of 35cm and a length of 6.5m. The height of the net is based on the tide level, and the buried depth is 50cm. The upper part is 1m higher than the highest tide level. The block was sewn with a 40 mesh polyethylene net, and the upper part of the bamboo raft was reinforced with a 10x3 polyethylene rope. A gate opened by managers from the earth embankment.
Second, seed stocking
1. Site clearing: The black sediment sludge is removed and then exposed to plowing. The depth is generally 15-25cm. After sun exposure, the sediment is oxidized and the water is softened. If there is less surface mud, you can use soft mud to cover the bottom.
2. Beach surface treatment: Before sowing seedlings, the plough or hoe can be used to plow the land and flatten the beach. Dig the shallow ditch along the direction of the tide and divide the beach surface into several blocks, each about 5m wide.
3. Disinfection and detoxification: Advanced water immersion must be performed 10 days before stocking, spray the flat beach surface with 20%c bleaching powder to kill the enemy, and the residue liquid should be washed into the drain several times after use. Only after the failure to broadcast seedlings.
4. Sowing: Slough seedlings are sown in February-March, when the bacteria are small, the temperature is low, they are easy to transport, and the survival rate is high. Seed specifications require 3000 6,000 seeds/kg, and seeding density is controlled at 200,000 grains per acre, generally no more than 250,000 grains. 2 to 3 hours of beach dehydration should be maintained 2 days to 3 days after the broadcast, in order to facilitate the deep burrowing of seedlings.
Third, daily management
1. Adjust the water level flexibly according to seasonal climate changes. In winter and spring, the temperature is low and the sunshine is strong during the day. The water level is controlled at 4Ocm-50cm to improve the water temperature, promote the growth of loach, and reduce the temperature at night. In particular, when the cold current is encountered, the water level should be increased to 80-100cm. After the summer, the weather is hot and the water level should be kept above 1.2m to prevent the water temperature from being too high and affect the growth of loach and prevent the propagation of algae on the beach.
2. Seine protection: The role of the seine net is to prevent enemies from invading people in order to reduce the use of drugs, prevent environmental pollution, increase the survival rate, and increase production. Therefore, before the advent of the gale, we must carefully inspect the tightness of the seine network, identify hidden dangers, and eliminate it in a timely manner to ensure the safety of the seine net. After the storm is over, we must immediately check the seine net and find leaks and repair it in time. To prevent the invasion of enemy pests.
3. Regularly in the dew: to adopt water retention and nourishing methods to extend their feeding time, according to the muddy living habits, must be regularly dew, so that the mud can maintain a faster growth rate. It is advisable to dry once or twice a month.
4. Elimination of predators: The predator organisms that are harmful to loach are ducks, foreliodes, short-toothed pods, jade snails, canola, crabs, etc., and the purse seizures are less harmful to the enemy, and appropriate measures can be taken depending on the circumstances. Carry out, capture, or kill elimination.
four. Harvesting loach at a timely manner The harvest time can be determined according to the specifications and market needs, generally from the annual Xiaoxue to the Qingming next year. At this time, the mud loach has the best fatness, high net rate, and good price. However, in order not to affect the production arrangements for the next year, the loach harvest cannot exceed the Spring Festival to facilitate dredging, exposure, renovation, renovation, etc.

Canned Tuna is an important variety of canned fish, canned tuna processing is the main species of albacore tuna and yellow-fin tuna, canned tuna has many varieties, including Canned Tuna in Brine, Canned Tuna in Tomato Sauce, Canned Tuna In Sunflower Oil, Canned Tuna in Vegetable Oil. In addition the tuna muscle more sulfur-containing protein, generally use the anti sulfur acid tin coating as a whole and canned container.

Canned fishes are made in our sub company-Zhejiang XingWang LongSheng Food Co.,Ltd. The company now has two factories(can branch and loin branch) and the main production equipment are: 3 processing capacity of 60 mt(materials)/day canned fish production lines; 4 processing capacity of 50 mt(materials)/day frozen cooked tuna loin production lines; 3 freezing capacity of 80 mt/day freezer rooms and 1 disposing capacity of 1000m³/day waste-water treatment plant. All the key equipment of every plant are imported from Thailand or Japan.

We will always strive to create more delicious, natural and safer marine health food.
