How Do I Start an Aquaculture Business?
Aquaculture is the use of aquaculture (including planting) waters by human beings. In accordance with the ecological habits of the culture objects and the requirements of the water environment conditions, aquaculture technology and facilities are used to engage in aquatic economic animal and plant breeding. One of the agricultural production sectors.
Aquaculture
- Aquaculture is available for human use
- According to the breeding waters, aquaculture can be divided into freshwater aquaculture, marine aquaculture, shallow beach aquaculture; according to the breeding object, it can be divided into fish farming, shellfish farming, shrimp farming, crab farming, algae cultivation; Divided into intensive culture, extensive culture, monoculture, polyculture, factory culture and still water, flowing water culture.
- The development of aquaculture is of great significance, as shown in the following: Can provide high-quality animal protein food for human beings economically. In animal feeding, fish are aquatic temperature-changing animals. Compared with terrestrial constant temperature livestock and poultry, they have less energy consumption, higher feed conversion efficiency, and higher animal protein content. It can provide raw materials for industry, and is an important source of raw materials for the pharmaceutical industry, chemical industry, and feed industry. It plays a significant role in making up for the shortage of marine fishing. With the rapid growth of the world's population and economic development, humans' demand for animal proteins is increasing, but the catch is limited by the renewal of natural fishery resources. The fishery forecast points out that the trend of increasing annual catch has reached its peak, and in the future, the natural fishery resources alone will not meet the demand. Conducive to maintaining ecological balance. In offshore areas, the increase in aquaculture production can reduce fishing intensity and prevent ecological imbalances caused by overfishing. Inland waters, the combination of aquaculture and other agricultural production is conducive to the formation of a virtuous ecological cycle.
- China is one of the earliest countries in the development of freshwater fish farming in the world, and its history can be traced back to the Yin Dynasty more than 3000 years ago. In the long-term production practice, people have accumulated and created rich fish farming experience and complete fish farming technology. China has excellent natural conditions and vast waters. According to statistics in the early 1980s, there are about 250 million acres of fresh water, accounting for about 2% of the country's land area. Among them, 75 million acres of water can be cultured, and there are plenty of rice fields. It has fish culture conditions; the coastline of the mainland is 18,000 kilometers long, and the bottom slope of most sea areas is small, the average depth is not large, the shallow beaches are wide, and the cultivable area is about 20 million mu, which has great breeding potential. In 1985, China's total aquaculture production reached 3.09 million tons, accounting for 43.8% of the total aquatic product output. Among them, the inland waters aquaculture production was 2.38 million tons and the shallow beach aquaculture production was 710,000 tons.
- In 1982, the world's aquaculture production exceeded 8 million tons, accounting for 1/10 of the world's total fisheries production, of which mariculture and freshwater aquaculture production each accounted for about half. The developed areas of aquaculture are mainly concentrated in some countries in East and Southeast Asia, and their production accounts for about 85% of the world's total aquaculture production, of which China accounts for more than 1/3. In addition, the Soviet Union accounts for approximately 6%, and the Americas and Europe each account for approximately 2%.
- Raise fish first. Water is the environment that fish depend on. Better water quality can reduce the occurrence of fish diseases and is more conducive to the growth and survival of fish. In actual production, the quality of water can often be judged by changes in water color, ammonia nitrogen content, and sediment color.
- 1. The red color of red water ponds is mainly caused by diatoms or diatoms becoming dominant populations, which is usually not a big deal. However, once the weather changes, causing a large number of algae to die, toxins will be produced and the water body will even deteriorate. Fish poisoning died. Therefore, once the pond water turns red, it must be improved in time. When the weather is fine, first sterilize with Sijian or quaternary ammonium salt iodine, and then spray with hydrogen peroxide, strong chlorin, etc. once on the second day, and then topdress as needed after 3 days.
- 2. Black water When the pool water is black, it indicates that more organic matter in the pool has not been converted in a timely manner, such as bait, animal residues, excreta, humus on the bottom of the pool, etc. After these materials are corrupted, a large amount of dissolved oxygen is consumed, which is likely to produce sulfur Harmful substances such as hydrogen, ammonia nitrogen, and nitrite can endanger the health of aquatic animals, reduce their immunity, cause infection by pathogenic microorganisms, and even cause fish ponds. Once such black water is found, chlorine-containing drugs such as hydrogen peroxide are applied once on the first day to the second day to oxidize too much organic matter. After 3 days, splash it once with Baifeng Energy Pure Water King Pond.
- 3 White turbid water When the pond water is white turbid, it indicates that there are too many organic oxygen-consuming substances in the pond. Relatively speaking, there are fewer microorganisms that decompose large organic matter into nutrient salts, causing phytoplankton to fail to obtain nutrients and cause a large number of deaths. The material circulation in the pond is damaged, the water in the pond is close to aging, and there is a severe lack of oxygen. The fish in this pond is generally prone to floating heads before the sun rises from dawn to dawn. When the pond water was found to be white and turbid, apply "Shuibao oxygen package" on the first day to make the organic matter oxidize in time after flocculation. On the second day, apply Baifeng Aquatic Products once to increase the active microorganisms in the pool and promote Water substance circulation.
- 4 Feed high-protein feed, chilled meat, or intensive fish ponds that feed on live fish such as crab ponds, prawn ponds, mullet ponds, and catfish ponds with high ammonia nitrogen content. After high-protein diets, the ammonia nitrogen content in the metabolites is too high, which affects the aquatic animals' feeding and growth, reduces their immunity, and easily causes parasite or pathogenic microorganism infection. Therefore, intensive ponds that feed on high protein feeds, chilled meat or live fish, apply ammonia net or pond bottom net once every 10-15 days to degrade ammonia nitrogen in a timely manner. If you pass the water quality test and find that the ammonia nitrogen content in the pool water is seriously exceeding the standard, you should timely apply ammonia net and oxygen treasure to the pool, and then spray once with fertilin, fertilizer and water treasure on the third day to increase the active microorganisms in the pool and promote planktonic The reproduction and growth of living things enhance the material circulation ability of water bodies.
- 5. Due to the humic deposits in the pond water, animal debris, bait, and feces sink into the bottom of the pond to decompose and decompose, causing the pond bottom mud to become black and stinky, which can easily produce methane, hydrogen sulfide, nitrite and other harmful substances It is easy to pose a threat to aquatic animals living in the middle and lower layers, such as catfish, grass carp, herring, crab, shrimp, catfish and other species. In severe cases, aquatic animals in the lower and middle layers of the pond often float in the upper and middle layers, and do not want to go to the normal living water layer. If the above situation occurs, Baifeng Aquatic Po should be applied once every 10 to 15 days to increase beneficial microorganisms, accelerate the transformation of organic matter or humus that sinks to the bottom of the pond, and avoid black sediment, odor and methane production, Harmful substances such as hydrogen sulfide and nitrite. It is found that the sediment in the pond is black and the water is stinky, and water change measures should be taken immediately. After the water change, the active water purification king is applied on the first day and the fast-acting fertilizer Shuibao is applied on the second day to adjust the water quality.
