Practical techniques and precautions for breeding sea bream in ponds

First, the choice of ponds and preparations Begonia aquaculture generally choose to enter and drain convenient, an area of ​​more than 30 acres of shrimp breeding ponds or reservoirs, depth of 1.5 meters or more, steep pool walls, the bottom is relatively hard. If the slope is too slow, a fence should be added at a depth of 0.5m on the shore, and a 10cm sieve screen should be 30cm above the water surface. The role of the seine net is to prevent sea otters from being stranded in shallow water due to wind waves, water flow and other factors. Wild miscellaneous fish and crabs are the main enemies of the sea lice and must be thoroughly removed before they are released. The first water injection is usually 10 to 20 centimeters. The whole pool is splashed with lime (100 kg/mu) or bleach solution (3010-6). The inlet and outlet shall be provided with a 40 mesh to 60 mesh screen to prevent the entry of wild fish and other predator organisms and to run seedlings when draining, and to adjust the size of the mesh with the growth of individual seedlings. Jellyfish mainly filter for small zooplankton in water. The amount of plankton in the water directly affects the survival rate and growth of Jellyfish. Therefore, it is necessary to apply fertilizer and water about 10 days before seedling release. Normally, 300 kg of organic manure is injected into fermented chicken dung per acre. Depending on the water's fatness, N and P ratios of 10:1 nitrogen fertilizer and phosphate fertilizer can be used as a supplement. Water quality related physical and chemical factors should be tested before laying seedlings. The suitable temperature range for sea bream breeding is 15°C~34°C, the optimum water temperature is 18°C~28°C; the suitable salt range is 8 ‰~37 ‰, and the optimal salinity is 16 ‰~28. ‰; ph value 7.5 ~ 8.5, no other pollution. Second, there are three methods currently used for the seed source: The first one is to capture natural seedlings at sea.
The second is semi-artificial seedlings. In other words, the sea bream that matures at sea is harvested, and the seed is obtained by artificially attaching the base. The third is artificial seedlings. The use of adult clams or artificially cultivated clams is used to obtain high quality seedlings through intensive cultivation and propagation. When the seedlings grow to 1.5-2 cm or more, they can be used as seedlings.
Third, seedlings should be selected for transporting seabream seedlings that are healthy and lively, and whose central mouth is closed and whose umbrella diameter is more than 2 cm. The apparatus used in the transportation process of the jellyfish seedlings depends on the temperature and the distance. The short-distance transportation can use various instruments with smooth inner walls without oxygenation. Long-distance transport generally uses a plastic bag for oxygenation. The transport density of pups with an umbrella diameter of 2 cm is 600/l to 700/l. If the transport time is longer (more than 5 hours), appropriate cooling and density reduction should be considered. Guarantee the survival rate of transportation. Pay attention to light during transportation.
4. Plankton biomass in stocking ponds is a key factor in determining the growth of sea otters. Therefore, the number of sea lice should be strictly controlled. At present, the number of commercial jellyfish harvested in artificially-cultivated ponds is generally around 27 heads per mu, with an average body weight of 5 kg to 10 kg and a maximum weight of 15 kg. Therefore, according to the different survival rates of different diameters of seedlings, the amount of seedlings is different. Generally, the young seedlings with an umbrella diameter of about 2 cm have a seedling density of 250/mu to 300/mu. Regardless of the farming method, it is better to adopt the method of placing the seedlings in rotation in stages. As sea otters grow rapidly, they can be harvested in about 50 days, and the breeding period suitable for the growth of sea otters can reach 110 days to 120 days in our province. Therefore, adopting catches and rotations can effectively use aquaculture water bodies to increase economic benefits. When the natural temperature of the outside world is stable above 20°C, choose sunny and windless weather to prepare for planting seedlings. Place the seedlings in the morning and evening to avoid direct sunlight. When the seedlings are transported to the poolside, the bag mouth should be unwrapped to observe the seedlings. In the case of vitality, the seedlings are then poured into a relatively large container, allowing the seeds to adapt for 10 minutes to 20 minutes. The seedlings are then transported to the middle of the pond with a boat and placed evenly in the pond. Alternatively, the plastic bag can be placed in the pool water and allowed to stand for 20 minutes. The bag opening is opened so that the pool water can be slowly poured into the bag, and the baby can be placed in the pool after 10 minutes. If there is no boat to transport the seedlings to the middle of the pond, the seedlings can be placed on the tuyere on the pond, and the operation process should be carried out slowly to prevent injury.
5. After the breeding period is put into operation, the water level should be gradually deepened to more than 1.5 meters, and the fatness of the pool water should be maintained. The transparency should be controlled at about 30 centimeters. The jellyfish is mainly produced by zooplankton in water and has a high food intake. Instead of manually feeding the bait, maintaining a large amount of zooplankton in the water is the key to the normal growth of the jellyfish. In general, depending on the change in water quality, organic fertilizer such as fermented chicken manure is applied 2-3 times per month, and the amount of fertilizer applied is controlled at about 100 kg/mu. In ponds where organic fertilizers are lacking or are not suitable, they can be replaced by inorganic fertilizers. They can be applied to urea at 1 kg/mu to 2 kg/mu, superphosphate 2 kg/mu to 4 kg/mu, and the water color is preferably brown. . With the growth of sea otters, their individuals continue to grow, especially in the middle and later stages of aquaculture (ie, one month later). The amount of sea otters is large and the water quality requirements are becoming increasingly stringent. At this time, water intake and drainage are not timely and water quality is relatively poor. When it is poor, it can easily cause a large number of sea lice deaths. The number of daily water changes should be kept at 10% to 20%, and the tide should reach 30%. Increasing the water exchange volume is one of the key technologies to ensure the increase of yield and recovery rate, but it is generally not necessary to change the water in the first 10 days. . The sea otters have the habit of floating in the morning and evening. After the jellyfish seedlings are released, they should stick to the morning and the evening. Check the water biomass, water quality, physical and chemical factors, and the growth of sea lice, and return the larvae in the pool to deep water. In summer high temperature season, when the water temperature exceeds 28°C, the amount of water evaporation is large, and the physicochemical factors of the pond water are greatly changed due to the increase of ph value and sudden rain, and it is always a big problem to easily reduce the survival rate of sea bream. It remains to be studied.

Whole ( Multi bulb ) Black Garlic is made of the whole fresh white garlic .

It appears black in colour and shrinks during the fermenting process. 

The cloves varies in diameter between 5.0 - 6.0cm and weights in at 30-40g before being peeled.
