Welcome back to Farmers' Welfare Channel. In the first part of today's broadcast, Farmers' Welfare will send you and your friends the techniques to raise African fish for high productivity, and the second is to raise African fish for 700 million VND. And the last one is the story of starting a business from raising fish in a pot of 1 billion VND per year. There are quite a lot of farmers in Hai Duong province who earn billions of VND per year by farming in the sea. Nguyen Hieu Doan's family is one of them. Let's find out together. The technique to raise African fish for high productivity. African fish are herbivores, which are highly resistant. Therefore, they can grow and develop well in many different breeding models. During the breeding process, people also need to pay attention to some factors to have the highest effect. Formation In the ground pond, the pond has a favorable position near the source of clean water, easy traffic, the area of the pond is about 500 to 1,000 square meters. In the cage, the cage must have clean water that is not polluted by life-giving water and industrial waste. Choose a spacious place, should not be raised at the ends of the pond, the area of the cage must be larger than 20 square meters. In the rice field, the rice field used to raise African fish has to have a field to release fish. The field area accounts for about 20 to 30% of the field area, about 0.8 to 1 meter deep. Preparation With the above feeding forms, the model of raising African fish in the ground pond is the most popular and common. Accordingly, to prepare for breeding, the cage is removed, cleaned, milked, and raised. Wipe off the bottom mud, use a sponge with a volume of 10 to 12 kg per 100 square meters of the cage. The sponge is spread evenly all over the surface of the cage, pay attention to the place where there is a lot of water or mud, there must be more mud. Spray the bottom of the cage for 3 to 5 days to eliminate the disease in the cage. Use a net with a size of 0.5 to 1 mm to filter the water, to prevent contamination of water into the cage. The water level in the cage is about 1.5 to 1.7 meters. Some environmental factors need to be ensured. Water temperature 25 to 300 degrees Celsius, pH 7 to 8, saltiness is less than 0.5, the amount of oxygen dissolves is always greater than 3mg per liter. There are many different types of African fish, but the most popular is the African fish of the Gid type, the red African fish, the pink African fish, and the brown African fish, which are the most popular. Pink is a variant of the African fish. The scales on the body are dark yellow, light yellow or pink red. You can also find fish that are yellow, pink, brown, but black scales. The Gid type of African fish is fast-growing, beautiful appearance, delicious quality of meat, and large size of products that require export processing. African fish, in recent years, the African fish of the Gid type is more popular, with the advantage of fast growth rate, the ability to fight diseases and withstand high cold. The nature of the African fish is the F1 generation of the two types of blue and silver African fish. The African fish has an average growth rate of 1-1.4 kg per fish over 6 months, 1.4-1.6 times the Gid type, producing 20-21 tons per hectare. The season of the Gid type is around May, but the best time is early April-June. The Gid type is chosen as strong, not strong, fast-flowing, flexible, even weight. Avoid choosing fish that are distorted, pale in color, weak in swimming, too small or too large. Breeders should buy from well-known aquarium facilities. The appropriate size of the aquarium is about 4-6 cm. Release the aquarium before releasing to eliminate parasites on the fish. Breeders should bathe with salt water 2-3%, 20-30 grams of salt per liter of water. The best time to release the aquarium is when it is cool. Before releasing, you need to put a bag of fish in the water for about 20-30 minutes to help the fish get used to the temperature of the aquarium environment. The average depth with a fish size of about 4-6 cm per fish releases a depth of 5 fish per square meter. However, if the aquarium is deep, it can release about 10-15 fish per square meter. For the cage, note that the fish must be raised in the aquarium until the size is larger than 20 grams per fish to release the cage. The depth released on the lake is about 30-50 fish per square meter. Food You can use many types of food to raise fish in Africa, but the best is to use industrial food. In which, using high-end industrial food will limit dehydration and reduce water pollution in the cage. For fish, eat industrial food with a protein content of about 18-35%. At first, it is better to eat food with a protein content of 30-35% to make the fish grow faster, have resistance to diseases and increase the living rate. Feed the fish twice a day in the morning and evening. In the first month, feed the fish 7-10% of the fish weight. In the second month, feed the fish 5-7% of the fish weight. In the third month to the fourth month, reduce the remaining 3-4% of the fish weight. From the fourth month on, feed 2-3% of the fish weight. At this stage, the amount of food is lower, about 18-20%. To save money, many places use homemade food that is fed in the morning in 2-3 places in the cage. Check the food every day to adjust the amount of food to suit. Day-to-day care Every day, check the cage, cage, net twice to prevent the fish from spawning or escaping out. Instead of feeding the cage, starting from the second feeding month, you need to install a water pump to ensure the amount of oxygen in the cage and avoid the phenomenon of fish floating. Note the times of oxygen deficiency, from 3am to 7am. On dark days, bad weather, you need to turn on the water pump. Maintain a stable water level, regularly change the water 1-2 times per month, change about 30-50% of the water in the cage, ensure that the food is full of nutrients and quantity. Regularly add more vitamin C, B-couplet, in the fish's diet to increase resistance and stimulate fish digestion. Tools such as nets, nets, hook, used for the cage, the cage must be cleaned and well-kept after use. After each feeding, the cage must be emptied, the cage is fed. For cage feeding, regularly clean the cage twice a week to get rid of impurities, wash the impurities cleanly and outside the cage. Regularly 15 days or 1 month carry out fishing, check the quantity and the level of fish food consumption for suitable adjustments. During the feeding process, once a month, feed 4 elephants with a volume of 2 kg per 100 square meters, mix the water evenly all over the cage. For cage feeding, carry out cage feeding in cages. Harvesting, after about 6-8 months, the fish reach the product size, then it can be harvested. Currently, there are 2 popular harvesting forms, harvesting or harvesting all. Note, when pulling the net, you need to do it gently to prevent the fish from being crushed, let the fish stop eating one day before harvesting. Hai Duong, a farmer who raises fish for free earns 700 million VND. Thanks to his stubborn personality, eager to learn, Mr. Kien has mastered the technique to successfully raise this fish. In terms of shape, the fish is easy to recognize because it has a short body, small head, high back, a curved trunk, thick flesh, no gills, delicious fish flavor, belongs to the type of clean fish, so the market is very favorable. For fish species, although non-profit, in addition to food resources, used from vegetables, fertilizers, the people should use high-quality industrial food, ensure the density according to the exact age of the fish. For small fish, feed 2-3 times a day, after the fish reaches the weight of 100 grams, only 2 times a day is enough. Feeding needs to be ensured according to the 4 rules, location, time, quantity, and quality. The value of the product when exported is related to the quality and origin of the food that the people use. As of mid-December, he has sold more than 10 tons of fish species in total. Recently, he sold 2 tons of non-profit fish, usually paid 35,000 VND per kilogram, each weighing an average of 2.3 kilograms. This time, he received 160 million VND without tax. Currently, there are still some fish that are ready to be sold at the beginning of next year. Mr. Kien estimates the situation of harvest up to now is more optimistic than last year, estimating a loss of more than 700 million VND. Another family living in the same area also chooses the form of non-profit fishing for many years is Mr. Le Thanh. With an area of 2.7 acres, he releases 1.2 million non-profit fish, 2,400 dead fish and about 200 dead fish. Although this non-profit fish is not difficult to raise, it needs to pay attention to prevention. For fish farms, the high rate of raising usually leads to the phenomenon of oxygen deficiency in the water. Mr. Thanh has invested 3 systems of round plates to increase the oxygen level in the pond to prevent the epidemic. At the same time, now is the end of the year, he advises people to make a reservation from 1 to 2 times a month to use mosquito or biological products to manage the water in the pond. Enhancing the use of vitamin C, minerals, mycobacteria helps the fish increase resistance, good health. The start-up of fish farming in Ao Noi is 1 billion VND per year. Not trained by the school of aquaculture, but the farmer Nguyen Hieu Doan still successfully started his business from sweet fish farming. Until now, the average annual income of the Doan family has produced and supplied to the market 7 million fish and 150 tons of fish of all kinds. The revenue is estimated to reach 10 billion VND, the profit below 1 billion VND depending on the year. Expected by 2020, the total number of Ao in the plan put into operation is the income of the Doan family will be higher than expected. Guiding us to visit the fish farm of the Doan family said the reason he led him to fish farming was because in the poor childhood months, he had to follow his parents to catch natural seafood. He has mastered the lifestyle of many kinds of freshwater fish. So, right after founding the family to live independently in 2000, he decided to start a fish farm by remodeling 1,800 square meters to form fish ponds. In the direction of short-term long-term short-term long-term remodeling mainly raise amphibians zoophiles and V1 cephalopods. According to Doan, amphibians and amphibians are fast-growing farming species that resist good conditions and can take advantage of the time to harvest agricultural products such as vegetables, grass, banana, fish food in the direction of remodeling to reduce investment costs and increase production efficiency. Thanks to many ways to build it up, just after 5 years Doan's family has invested a lot of capital to rent more of their farms to expand the area of fish ponds to 5,400 square meters. Every step of the process expands the area of production like that until 2015. Doan's family has expanded the area of fish ponds to 11 hectares including 8.5 hectares of fish pond and 2.5 hectares of fish pond pond. In fact, across the farms we see all fish pond are built high and the pond is always spacious. The grid system is installed in the same place and the machinery can easily be transported to the pond. Looking back the whole process of fish farming, Doan said to be able to develop and become rich by farming, the investor only needs the experience of fish farming is not enough. It needs more skills to manage the farm and know how to use and create the fish farming experience that is actually produced. In the past, fish farming was a short-term and long-term business. But fish farming on a large scale from 5 to 7 hectares does not necessarily have to be combined with the farm. The wider the pond area, the more sunshine and natural water flow, the faster the fish grow. So avoid fish farming in ponds with doors, ponds with south-eastern wind direction where there are ponds. With fish ponds there is more time for fish to eat before the weather changes and the days are hot and extremely hot. It is necessary to invest and have a farm with fishing equipment such as a generator, a water pump, a generator, a generator.
