What Is Fish Breeding Pond?

How to solve the problem of sewage filtration in fish pondsOne of the several issues that people in the aquaculture industry are more worried about during the breeding process is the sewage filtration of fish ponds. After all, breeding is related to water. The quality of the water body determines whether the breeding can be successful. Traditional fish ponds are In the natural environment, dirt can settle at the bottom of the pond and be naturally resolved, absorbed and transformed, but in artificial ponds it must be resolved through artificial means.Outdoor galvanized sheet canvas fish pondThere are many methods and modes of fish pond filtration. For example, equipment filtration is a water circulation mode that uses a microfiltration machine to separate and precipitate fish excrement and bait residues, purify the water and put it back into use again. There is also biological filtration, which is common. There is an aquaponics system model, which uses vegetables floating on the water to absorb fish excrement as nutrients and make soilless vegetables. It not only grows vegetables but also purifies the water. It can also precipitate and filter out larger impurities. , and finally clean the water body through a microbial pool to the point where fish can be raised again. It is also a water-saving circulating aquaculture model, which is more ecological and environmentally friendly and has less impact on the environment.Large canvas fish pond breeding baseThe new aquaculture equipment galvanized sheet canvas fish pond is simple to install and build, has a long service life, the material is environmentally friendly and does not pollute the fish, and the requirements for the terrain are relatively flexible. Wolize Company believes that intensive management can carry out high-density aquaculture with higher benefits. , is now a popular choice for many people in the aquaculture industry. Galvanized sheet canvas fish pond farming has filtration and sewage problems. Many farmers also choose to adopt the filtration mode of aquaponics. The "double harvest of fish and vegetables" has higher environmental benefits.Fish farming canvas pondFiltration of Canvas Fish Ponds When installing fish ponds, many farmers will choose to make the bottom of the fish pond into the shape of a pot bottom and then equip it with a fish toilet. The advantage of the pot bottom shape is that dirt will gather on the fish toilet along the slope and then be discharged, so The working principle of the fish toilet is sedimentation. Is the fish toilet easy to use? The fish toilet collects feces very conveniently and quickly, and can be said to be easy to use. The installation location of the fish toilet can also be determined according to the planning of the breeding base and the direction of the pipeline, which is also relatively flexible.

1. Management of koi fish breeding water bodies You can choose to use groundwater, river water, tap water, etc. to breed koi. To make the color of koi bright and shiny, the water quality must be adjusted to the ideal state. Ideal water quality requires a slightly alkaline pH of 7.2-7.4, low content of iron ions, chloride ions, and sulfate ions, sufficient dissolved oxygen, and low hardness. Groundwater is often rich in heavy metal ions and has low dissolved oxygen, so it must be specially treated to be suitable for the growth of koi. The river water is often turbid, which is not only unsightly, but also contains some harmful substances such as 2 meters of waste water, etc., and the ammonia nitrogen is high, so it must be biochemically filtered before use. Tap water is treated water and comes from a convenient source, but the residual chlorine in the water is harmful to koi and must be dechlorinated. Aeration is commonly used to decompose and disperse the residual chlorine in the water before adding it to the fish pond. No matter what kind of water it is, it is not advisable to add too much new water directly into the fish pond in a short period of time, otherwise the fish will not be able to adapt and cause health problems. Rainwater has a low pH and contains a large number of undesirable factors, so it should be avoided as much as possible to mix it into the pool. 2. How to build a koi breeding fish pondThere is no certain rule for the size of the pool. In order to watch the heroic swimming posture of the koi, it is usually better to make it bigger and deeper. The general requirements are 15-35m2 and the water depth is 1.2-1.8m. In northern areas, a depth of about 1.8-3M is better, and at least 80cm. If the water body is too small and shallow, it is difficult to breed huge koi, and shallow water is easily affected by the weather and sunlight. When it is hot, the water temperature rises. In winter, the water temperature is too cold, which often makes the fish feel uncomfortable and causes diseases. The walls inside the pool should be smooth and the pool surface should be as wide as possible. Uneven stones should not be used to avoid harming the koi. Try to avoid the appearance of stagnant water levels in the fish pond. The fish pond should be made into a streamline shape. Generally speaking, a square fish pond is easier to manage and convenient for feeding and viewing. It is best for the pool to have 2-3 hours of sunlight every day. There should be no large deciduous trees near the pool to avoid damaging the water quality. The steps to build a pool are as follows: (1) Dig the bottom of the pool deeply. If the bottom is soft, foundation treatment must be carried out, such as placing stones, driving piles, etc., to level the foundation. (2) Install underground drainage pipes. (3) Tie steel bars and put concrete on the bottom and sides of the pool, and be careful to prevent water leakage. (4) Pay attention to the matching of fish pond and filter pond. (5) Trim the bottom and surroundings of the fish pond, and apply cement to make the bottom and surroundings smooth. The bottom of the pond and the central drainage pipe are at an angle to facilitate drainage. (6) Check whether the inlet and drainage pipes and water pumps can operate normally, and check the circuit and oxygen supply system. 3. Types of fish pond filtration and how to build fish pond filters Most people think that filtration is just about removing suspended matter from water and making the water clear. In fact, its role is far from that. The complete biochemical filtration system can not only remove suspended solids and excess algae in the water, but also can not only remove suspended solids and excess algae in the water through the filtration system, but also decompose harmful substances in the water, such as ammonia nitrogen, through the biochemical bacteria in the filter village , nitrite, etc., to convert them into substances harmless to fish. Filtration is divided into: (1) physical filtration (2) chemical filtration (3) biochemical filtration (4) plant filtration (1) Physical filtration is to use various filter materials or auxiliary agents to remove dust, jelly, suspended matter, leaves, etc. in the water to keep the water transparent. The more traditional and simple method is to use sand and stone particles to penetrate the water to remove floating matter visible to the naked eye. Generally, the most commonly used fish pond filter brushes, fish pond biochemical cotton and other filter materials have dual functions of physical filtration and biochemical filtration. (2) Chemical filtration is a filtration method that uses filter materials to remove various ionic compounds or odors that are harmful to fish dissolved in the water by absorption. Commonly used filter materials include far-infrared bacteria house coral sand, medical stone, phosphorus stone, etc. (3) Biochemical filtration is to use the nitrifying bacteria attached to the filter material to decompose the fish excrement, such as feces, residual bait and the nitrogen-containing organic matter or ammonia produced into harmless substances. It is the most important part of the entire fish pond filtration system. Commonly used filter materials include PuLushi fish pond filter brushes, fiber cotton, far-infrared bacteria houses and biochemical balls. Be careful not to flush out or kill these bacteria when cleaning or disinfecting the filter tank. (4) Plant filtration uses plants in the water to absorb harmful factors in the water. Generally available water plants include duckweed, calamus, etc., which have well-developed root systems. In addition to the function of plant filtration, they can also absorb ammonia nitrogen and other fertilizers that are beneficial to plant growth. To make the pond water clean, suitable for fish viewing and to help fish grow and enhance their color, a filter circulation device must be usedThe specific method is to connect the water pipe from the deepest part of the fish pond bottom to the sedimentation tank. After being treated with various filter materials, it is pumped back to the pool with a circulating water pump to continuously filter the water body. The settling tank is the first part of the filter tank, where the suspended solids and heavy metal ions settle, and the bottom of the settling tank is connected to the drain through the valve to discharge the sewage. The size of the filter tank is about 1/3-1/5 of the fish pond. The larger the filter tank area, the better the filtering effect. If you want to add tap water or groundwater to the fish pond, you should put the new water into the filter tank and let it aerate for a few days to allow the residual chlorine in the tap water to evaporate. It is not advisable to add new water directly to the fish pond. Since biochemical bacterial decomposition requires oxygen, the filter tank must be equipped with a blast pipe to increase dissolved oxygen in the water. Air compressors are commonly used to press air directly into the water, and pure oxygen is also used. In addition, due to the strong sunlight in outdoor pools, germicidal lamps can be used to kill excessive green algae in the water. If necessary, a shading device can be used to cover about 1/3 of the fish pond to prevent ultraviolet rays from affecting the color of the pond water and fish. 4. Preparation before raising koi and daily management of the pool After the fish pond and filtration are completed, the cement alkali must be removed first and the water can be tested before fish can be raised. Because the new fish pond concrete contains a large amount of cement alkali, it needs to be soaked in water with glacial acetic acid. Generally, after the new pool is filled with water, add about 50g of glacial acetic acid to each 1m2 area of the pool and mix it evenly. After 24 hours, drain it and repeat it. After 5 days, drain it and soak it in clean water for 2-3 times, and then stock some cheap koi. Enter the pond to understand the safety of the water quality. If the koi respond well to the water test, you can place your favorite koi. Of course, since cement alkali will dissolve in the pond for a long time, more new water should be added in the first six months, and the health of the fish should be paid close attention to. If the reaction is not normal, the pond must be moved as soon as possible. The daily management of fish ponds requires attention to keeping the pond water clean. If there are non-fish feces or residual bait, leaves, etc., they must be drained away as soon as possible. It is generally best to drain the bottom water once every three months. The filter tank also needs to be cleaned once a year or so. Bottom sludge and drain away sewage. Draining substances harmful to fish in the water in a timely manner and maintaining good water quality are the most important points in pool management, and are also the key to raising koi well.

In recent years, with the rising prices of fishmeal and fish oil, plant-based protein sources have become more and more widely used in aquafeeds. Even for the compound feed of carnivorous fish, plant raw materials can account for 50% to 70%. As the current feed production tends to use cheap plant-based protein raw materials instead of high-priced animal-derived protein raw materials such as fishmeal, this will inevitably increase the hazards of mycotoxin contamination. With the widespread use of plant-based raw materials, the pollution of mycotoxins to feed raw materials and their finished products has become increasingly prominent.The hazards caused by mycotoxins to aquatic products are1. Cause poisoningThe ingestion of feed contaminated by mycotoxins by aquatic animals can lead to acute or chronic poisoning. Acute poisoning will cause symptoms of digestive system disorders, and even death in severe cases; the symptoms of chronic poisoning are various, and the hazards of different toxins vary greatly.2. Liver poisoningLong-term consumption of feed containing mycotoxins will lead to stunted organ development and changes in physiological functions of aquatic animals, and in severe cases, tumors or cancers will occur. And it can cause the content of alanine aminotransferase and aspartate aminotransferase in the fish body to increase, indicating that the liver function of the fish body is damaged. The most damaging mycotoxin to the liver is aflatoxin, so aflatoxin is also called liver toxin.3. Suppresses immunityEvidence suggests that ingestion of mycotoxin-contaminated feed in animals suppresses the immune system and reduces disease resistance, even at low or moderate levels of contamination. Mycotoxins that impair the immune system include aflatoxin B1, T-2 toxin, ochratoxin, deoxynivalenol and fumonisins (also known as fumonisins). Most of these toxins damage the immune system by inhibiting the synthesis of key proteins related to immune function.Although the presence of mycotoxins in feed is an increasingly serious threat to aquaculture production, feed mills and farmers still have a variety of options to prevent or reduce the risk of mycotoxins.What measures can reduce mycotoxins?1. Cut off the source of mycotoxinsControl mold growth conditions and inhibit toxin production. Control is carried out from the links of procurement, production, storage and transportation respectively. Source of raw material for each batch of feed. Each batch of protein and energy raw materials is tested for mycotoxins, and raw materials that exceed the control standards are strictly returned.2. Carefully select raw materials, maintain good feed and raw material storage conditions, and select effective mycotoxin detoxification agent products to solve the different mycotoxins as comprehensively as possible.3. You can add bile acids that protect the liver and gallbladder when feeding the feedBile acids can promote the detoxification and detoxification of the liver, stimulate the liver to secrete bile, and excrete toxins and mycotoxins in the body along with the bile through the enterohepatic circulation, restore liver health and enhance liver function; they can also repair intestinal mucosal damage and restore Intestinal mucosal injury, restore the compact structure of mucosal epithelial cells, enhance the mechanical barrier function of the mucosa, inhibit the reproduction of intestinal harmful bacteria, and maintain the intestinal microecological balance.The harm of mycotoxins to aquaculture is obvious. Every farmer should actively adopt various methods to reduce the impact of mycotoxins on aquatic animals, reduce production costs, reduce damage, improve breeding efficiency, and jointly maintain healthy water. product.
