Connect, share, good experiences in aquaculture Bring good models, reality to the people to move forward together and enrich the land of your hometown Don't forget to subscribe to the channel to get more videos Improve the technique of raising shrimp to visit the earth According to the evaluation of the Central Center for Agriculture in Bac Lieu, shrimp farmers in Bac Lieu are often faced with epidemics with the risk of outbreak The weather is getting more and more complicated and difficult to measure The soil and water environment are showing signs of deterioration and pollution In addition, the production organization plans to build an unguaranteed aquaculture project Some of the shrimp farming processes of the people are still limited Especially the selection of seedlings and the level of fertilization It is intended to determine the effectiveness of the production of the people I also advise people to catch seedlings in companies that have satellite brands If the conditions are good, you should set up cooperatives and cooperatives When catching seedlings, you will go together to catch seedlings of the same species Before catching seedlings for 2-3 days, you should come to visit the seedling farm of the company and take samples for testing If the batch is tested successfully, you should release it In fact, we see that in the models of Tôn Thâm Canh and Ngao Đắc People directly contact the company and release it, not come to take samples and test it like in previous years So now people have to have that connection to choose the best quality seedlings For the model of shrimp farming, to reduce the cost of raising and to avoid the situation of the shrimp spawning We also advise people to raise according to 2 stages, that is, the breeding stage and the raising stage After people have chosen seedlings, we also advise people to breed with about 30 shrimp per square meter For the model of shrimp farming in Ao Đắc, for an area of ​​2,000 square meters, you can go down 2 stages and release about 60,000-70,000 shrimp After about 1.5-2 months, people go to 1-2 more areas to avoid the situation of the shrimp spawning and reduce the cost of raising For the model of shrimp farming in Ao Đắc, people also try to release about 60-80 shrimp per square meter, but people should not release thick And now, according to some of our models, we see that when releasing shrimp, people like to release at an area of ​​over 100 square meters If so, it is very difficult, if so, about 100 shrimp, the environment will be very polluted, people will find it very difficult to raise And raising it will not have a high effect compared to raising it on a small scale To increase the effectiveness of creating breakthroughs in production, shrimp farmers need to continuously update and strengthen the improvement of the application of new technological advances in the production practice To reduce cost and increase economic efficiency In fact, it shows that shrimp farming in general is very profitable, but the risk is not small due to the impact of the weather and the environment In shrimp farming, the management of the environment will create conditions for shrimp to develop well Now, for the management of the environment, people raise shrimp in Ao Đắc Up to now, a person has been raising shrimp for about 15-20 years People feel that if you raise a piece of Ao Đắc, if you raise a lot of shrimp, the environmental pollution in the Ao Đắc Combined with the problem of poor nutrition in the environment and the pollution of heavy metals or diseases that last for a long time It makes the form and way of raising shrimp very difficult Because of these conditions, we also notice that people should add products to re-create the environment Combined with products that can stabilize, disintegrate, detoxify and solve the difficulties in raising Along with products that deal with the environment, we see that people use the products of the Ministry of Environment, Food and Rural Affairs They are doing very well in the management of the environment, detoxifying, detoxifying heavy metals and diseases in the Ao Đắc In addition, in addition to good environmental management, people also regularly use sanitary products to create a positive impact in the Ao Đắc As well as people can use some products to take care of the shrimp, so that their environment is stable In today's shrimp farming, shrimp farmers need to know how to manage shrimp health through each stage Shrimp diet must also be taken care of To improve the health of shrimp farmers, they need to supplement nutrients and vitamins for shrimp farmers by mixing them in food, in reasonable amounts To increase the resistance of the shrimp and to increase the resistance of the shrimp to limit the problem of attacks when the shrimp is in the rainy season and the shrimp is loose We also notice that people should choose products that contain vitamin C, or fertilizers, or phytonutrients to help strengthen the immune system of the shrimp and help the shrimp grow In short, we notice that there are 3 problems for us to do well As you know, shrimp disease depends on 3 factors The first is the environment, the second is the disease, and the third is the resistance For example, in the months from May to June to August, there is a lot of rain People combine it with the products on the shore For example, 1,000 square meters, we can break a bag of 50 kg and combine it for 5 to 7 days You can use about 2 liters of water per 1,000 liters of water On hot days without rain, about 14 to 15 pm, you can use 2 to 3 kg of water per 1,000 liters of water to protect the shrimp In addition, we try to observe the shrimp when the wind blows and observe the shrimp in the food If the color of the food is the same as the color of the food, it means that the environment is good and the shrimp is growing well Of course, in the case that you are raising and visiting the food, and when we pick it up, there are 3 colors in the food And there are colors that are different from the color in the food Then you should also add some pesticides or some pesticides For example, fresh garlic with a dose of about 20 to 30 grams per kilogram of food to stabilize the shrimp In that case, you can use iodine products to sterilize regularly According to the practical experience of those of us who do technical guidance At the moment, for the model of Canau Duck shrimp, even the shrimp of the stream, the shrimp of the river, it is about 10 days You should use iodine products to sterilize once With a dose of about 1 liter per 1,000 liters of water to 2,000 liters of water And you should sterilize at about 6 p.m. to limit the problem that the iodine will reduce the intensity of iodine And iodine, as I have shared with you, is a product that does not cause eye sores and does not cause shock to the shrimp And it is sterilized in a dry form, so it is very safe And after that, you should also take care of the problem of processing products to regenerate the environment regularly For example, 2 liters of iodine per 1,000 liters of water and combined with vitamin C And regularly sterilize about 7 to 10 days a time to improve the management of the environment On the other hand, raising shrimp in the canal requires the farmer to give up a fairly large source of income Must basically grasp the management and care techniques This is a complex issue that in the technical guidance, the practical world in production, as well as in the knowledge of farmers, is much more complex To increase the efficiency of production, farmers need to change the production method Apply scientific progress to production in a basic way It is necessary that the shrimp farmer must plan, cultivate the basic area and follow the correct technical process The process of processing water from the canal to the canal must go through a filter The process of causing water color, adjusting the salt content, alkalinity and pH must ensure the best combination for the development of shrimp When the environment is unfavorable for shrimp, we must know how to handle it When there is a flood, we must handle it according to the rules
