1. Pond conditions The development of gums should be based on the selection of dykes, smooth access to water, and sediment-bearing ponds. The height of the pond is better than 2m. Every 1/15 square hectare of land immediately prior to planting shall be thoroughly disinfected with quick-drying lime 70kg, and washed with fresh seawater with an 80 mesh filter until the seawater is fresh, and conditions may be equipped with sedimentation tanks.
2. The water quality requirements are high for pond aquaculture water use, but they are not significantly different from industrial aquaculture water use. Pay attention not to the seawater at the tide and the end of the tide. The required water must be fresh, the viscosity is small, and there is no light in the night spray. However, when the water temperature reaches 28°C in summer, the water level should be increased to reduce the surface temperature of the gingiva Fish and increase the survival rate.
3, the choice of seedlings to choose seedlings should consider the same color, pattern, clear fins, strong and strong vitality, stimulating or alarming instantaneous speed is better, black and white will not be. The best body length is 6cm or more. Before stocking, pay attention to the water temperature in the culture tank and the indoor holding tank. The salinity should be the same to ensure the adaptability of the gingival fry and increase the survival rate.
4, stocking density ponds cultured gums, suitable stocking density should be controlled at 1/15 square hectare put 1200 or so, it is best equipped with aeration facilities to prevent the use of summer or hot and windless weather, to prevent oxygen deficiency and Cause unnecessary losses.
5, feed feeding
5.1 Types of Feed The feed used for the gingiva pond culture is basically the same as that for the factory culture. At the initial stage of stocking, the short-term adaptability should be adopted. The best is to use granule compound feeds until it adapts to the changes in the environment. The fish is mainly supplemented by pelleted feed, mainly animal feed can improve the immune function of fish and enable it to grow rapidly.
5.2 Feeding Times and Feeding Frequency Feeding frequency and feeding amount should be flexibly controlled according to seed size, water temperature, weather, and actual food intake. In the initial stage, 3 to 4 times a day should be fed, when the fish body reaches 12cm in length. , can be appropriately changed to feeding 2 times a day, the amount of feeding according to the situation of ingestion of flexible control, the amount of daily feeding is 1% to 3% of fish weight should pay attention to disease prevention.
5.3 Method of feeding The pond cultured gingiva is generally fixed at several points, so that it can be fixed and fed regularly, strictly avoiding feeding in the whole pool. This can not only improve the feed conversion rate, but also ensure that the culture water will not be consumed by the residual bait. More pollution. Feeding methods should follow the principle of less-more-less, and begin to make fewer shots and slower feeds; when large groups of fish rush to eat later, feed more and speed up the feeding rate; most fish are full and sink into the bottom of the pool. Afterwards, cast less and feed slowly. It is worth noting that in the course of breeding, if the size of the fish is found to be polarized, the best way is to start feeding with pellets and wait until the big ones have enough food to sink to the bottom of the fish and then feed them again. . In order to avoid the occurrence of uneven size during harvest and affect the breeding efficiency.
6, daily management
6.1 Water quality control In the initial stage of stocking, it is best not to change the water. The adaptability of the gums is not very strong. If there is new water injection, it will stimulate the fast swimming and reduce the food intake, thus affecting its growth rate. As the fish grows, the amount of water to be changed gradually increases. When the temperature reaches 28°C, the maximum amount of water is changed every day to keep the water fresh and the oxygen is sufficient. In summer, high temperatures and little wind are the most prone to oxygen deficiency accidents. While continuously increasing the amount of water exchange, it is better to have pumping equipment and aerators to prevent the occurrence of dead fish due to lack of oxygen.
6.2 Daily Management Check whether there is any damage to the intake and drainage network and the safety and ruggedness of the frame and gate during the morning and check the problems and handle them in time.
7. The harvesting and selling time should be determined based on the market price and the temperature in the catch culture of the pond. Pond drainage should not be too dry, maintain a water depth of about 1m, to prevent birds from killing; capture methods for fixed-point capture; nets use ring nets to avoid fisheries injury in the capture process and ultimately reduce the impact on economic efficiency.
