I. Selection of jellyfish breeding ponds
1. Water sources and water quality Aquaculture ponds should be close to seawater sources, with convenient drainage and drainage. It is best to choose ponds that can use natural tides to enter and drain. There should also be fresh water sources in order to adjust the salinity of the culture ponds.
2. The area and depth of the pond The area of ​​shrimp ponds for breeding sea otters is about 100 mu. It is better to use an aquaculture pond with an area of ​​about 1,000 mu. The aquaculture pond is about 2 meters deep, preferably 2 to 3 meters deep.
Second, the culture of sea lice in water conditions suitable salinity of 13 to 32, the optimal salinity of 19 to 28, salinity is too low or too high should be adjusted in time. Suitable pH is between 7.8 and 8.9. The suitable water temperature is 18 to 28°C, and the optimal water temperature is 22 to 26°C. Note that the temperature of cultured sea bream should not exceed 32°C. If it exceeds the temperature, raise the water temperature and adjust the aquaculture water temperature.
Third, release seedlings, seedling density and high-yielding aquaculture technology
1. Seed size specifications 2 to 3 cm seedlings, strong seedlings can improve the survival rate of culture. The general breeding survival rate is about 30%, and the farming conditions are better up to 50%.
2. The seedlings are planted at a density of 100 to 300 mu, and the breeding pool is convenient for drainage and drainage. The water depth is about 2 to 3 meters, and about 500 mu of ponds are planted in good conditions.
3. The jellyfish seedlings are transported in plastic bags, transported with oxygen and shading, transported at a relatively long distance, and with high temperatures, ice and other measures should be taken.
4. Begonia multi-fish breeding techniques (1) One-time foot planting, harvesting and harvesting for multiple harvests.
(2) Put the seedlings twice, put the seedlings in advance, catch the fish for 40 to 60 days, and then put the seedlings for the second time, and harvest them after autumn.
(3) The seedlings were released several times and harvested many times. Early seedlings were planted and nursed by seedlings. After mid-May to mid-July and mid-July, seedlings were raised one after another. Harvested in mid-late and late September, and harvested from 3 to 4 cents of jellyfish.
5. Polyculture mode and technology for sea bream and shrimp, shellfish and fish (1) polyculture between sea bream and shrimp, shrimp and car. Polyculture of shrimp, acres of shrimp 1000 ~ 3000 tail.
(2) jellyfish and shrimp, shellfish polyculture. Can be mixed with shellfish, barley, clams, buttercups, clams and other shellfish polyculture. The amount of shellfish seedlings depends on the quality of the pond and the quality of the beach.
(3) Polyculture of sea bream and shrimp, shellfish and fish. Sea oysters, along with gums such as gums and puffer fish, need to be raised to a certain size before they are released. Otherwise, the survival rate of cultured oysters will be affected.
6. Retaining nets around the rearing ponds to increase the survival rate of the cultures should be set up in shallow ponds and poolsides of the rearing tanks. The height of the screens should not be flooded when entering the water, and the bottom edge of the screens should be left in the drain. 20 to 30 centimeters of water depth, blocking screen mesh to 20 mesh is better.
IV. Breeding management
1. Inlet and Drainage Management Aquaculture ponds should be filled with 60% of water before laying seedlings. After the sea bream stocks are stocked, new water should be added in time according to the water quality of the culture ponds to ensure that there is enough food organisms and sufficient dissolved oxygen in the culture pond water. .
2. Feed management Begonia mainly uses small plankton as bait. Mainly to feed on small zooplankton, such as copepods, Artemia, rotifers, shellfish larvae and so on. Normal breeding of sea lice can rely on the exchange of water to solve the food organisms and meet the normal growth of sea otters. Polyculture of shrimps, shellfish, and fish is normally fed as a polyculture.
3. Apply manure and water, increase the ponds with higher density of bait-feeding organisms, and apply fermented manure water in time according to the growth conditions of sea lice and polyculture. Or take some artificial measures to increase the feed amount in the culture pond.
4. Daily management The patrol pool will be conducted every morning and evening to check the water quality in the culture ponds and the growth activities of the sea lice, identify problems, and take timely measures.
5. Water quality regulation During aquaculture, regular monitoring of the water quality of the aquaculture ponds, especially during heavy storms, or close to freshwater sources, will prevent significant loss of salinity resulting from excessive freshwater volume, affecting the survival rate and normal growth of sea lice. If the salinity is too high or too low, the normal growth of sea otters will be affected in different degrees. Therefore, it is necessary to adjust the water quality in a timely manner to ensure that the cultured sea otters increase production and income.
Fifth, the timely harvest of jellyfish breeding sea otters grow fast, shrimp pond culture sea bream generally 50 to 60 days to reach commercial specifications. The aquaculture ponds are in good condition and the food organisms are abundant. The harvest can be harvested within 40 days. The normal breeding of 40 to 60 days a body weight up to 8 to 10 kg, should be promptly arrested.
6. Disease Prevention and Control Sea Bream Farming Currently, there is no disease, but the majority of farmed sea-breeding ponds are polycultured, especially polycultured shrimp, gums, and puffer fish, and shrimp and fish should be treated with caution when preventing diseases. Try to avoid affecting the normal growth and survival of sea lice due to drug administration.
Haiyan Shrimp Pond High-yielding Aquaculture Technology
In order to make full use of shrimp pond resources, vigorously promote the high-yielding aquaculture technology of sea otters, and improve the comprehensive utilization level and economic benefits of shrimp ponds. Based on the cultivation of sea breams in the five-year shrimp ponds of Donggang District, the authors have studied and obtained high-yielding aquaculture technology of sea otters and shrimp larvae. Successfully sorted out the high-yield technical points for the breeding of shrimp and shrimp ponds for reference by farmers.
