What fish and what fish and what aquaculture are mutually beneficial

In 2002, Zhou Zhangkui, a farmer in Siwei Village, Bawei Town, Jingjiang City, Jiangsu Province, contracted 3 acres of fish ponds to carry out fish and turtle polyculture, making a profit of 10,000 yuan that year and a profit of 5,600 yuan per mu. Next, we will give you a brief introduction to this breeding model: Stocking:

In February, 5,000 local fish species were stocked, including silver carp, bream, grass carp and crucian carp. In June, 500 soft-shelled turtles were introduced from Wuxi, a total of kilograms, each weighing 200-250 grams, and strictly disinfected with potassium permanganate before going down to the pond. Feed:

Adult fish are fed rapeseed cake, bean cake, aquatic weeds, etc. Before the turtle goes down to the pond, a large number of snails should be put in the pond in advance to build a food table, which is convenient for the turtle to eat and dry its back. 6-9 months is the peak period of soft-shelled turtle growth, should be fed fresh wild trash fish, shrimp and other natural bait, 2 times a day, 8-9 o'clock in the morning, 5-6 o'clock in the afternoon each once, the number of soft-shelled turtles can be eaten in 2-3 hours is appropriate, the remaining residual bait should be fished out in time, so as not to pollute the water quality.

Manage. The first is water quality management, and the water should be changed frequently in the high temperature season, so that the pH value of the pool water is kept at 7-8 and the transparency is controlled at 30-40 cm. The second is daily management, mainly to do a good job of patrolling ponds, frequently inspecting anti-escape facilities, observing changes in water quality and eating conditions, eliminating enemies and preventing diseases.

Capture. In late October, a total of 465 adult turtles were caught, with an individual weight of 600-750 grams, a recatch rate of 93%, and a total of 1,300 kilograms of adult fish. Benefit.

At present, the factory farmed soft-shelled turtle on the market has less muscle, more fat, poor taste, and low quality, about 40 yuan per kilogram; The quality of the soft-shelled turtle is close to that of wild soft-shelled turtles, with more muscle, less fat and good taste, ranging from 80 to 100 yuan per kilogram. Review. Fish and turtle polyculture makes full use of the water space of the pond, uses natural bait for ecological breeding, basically does not use fish medicine, maintains the quality and taste of wild soft-shelled turtles, and creates high economic benefits. Satisfied.

Nanjing Xinlu Biotechnology **** is a scientific research unit directly under the National University Science and Technology Park of Gulou University of Nanjing University, and now promotes the technological achievements of organic yellow eel and lobster and loach industrial ecological polyculture: 1. Introduction to organic yellow eel and lobster and loach ecological polyculture technology "Static water soilless ecological aquaculture and intermittent flowing water soilless ecological polyculture organic yellow eel and lobster and loach technology" was pioneered by Dr. Zhou Wenzong of the company. Successfully grafted ecological engineering technology to aquaculture, the use of special fish nests instead of soil, the use of aquatic weeds and water quality improvers to improve water quality, the use of ecological control technology for the comprehensive control of yellow eel diseases and insect pests, through the development of organic bait through food chain technology, not only to overcome the problem of excessive drug residues in artificial eel breeding, but also to reduce the cost to about 15 yuan per kilogram.

At the same time, it effectively solves the problems of "unsociable" and high-density breeding of small yellow eel, which is easy to rot tails, bleeding and various intestinal diseases. It is important to regulate the ecological environment from the level above the population, use the principle of biodiversity and symbiosis and mutual benefit to enhance the buffer, improve the survival rate and growth rate of high density of yellow eel, reduce auxiliary energy input, and reduce feed costs. Aquaculture water can be comprehensively utilized, making full use of straw, manure, aquatic weeds and other agricultural and sideline product scraps to produce live bait, the production park has no waste, and the ecological benefits are significant.

The cost of building a pond is low, it is easy to observe, it is easy to tame compound feed, it is convenient to manage, it is conducive to the prevention and control of pests and diseases, and the benefits are high. This project has been successfully tested and demonstrated in Jiangsu, Henan, Hubei, Shanxi, Jiangxi, Liaoning and other provinces and applied for 9 invention patents. In 2003, Dr. Zhou was invited to Hong Kong to provide comprehensive guidance on the technical work of the "Organic Yellow Eel Ecological Breeding Technical Service Contract" with Hong Kong Organic Farm located in Pat Heung Hoi Reservoir, Yuen Long, New Territories, Hong Kong, which provides organic food for high-level dignitaries in Hong Kong.

The technical achievements have been CCTV-7 (; Henan**", Jinling Evening News, Henan Rural Daily, Modern Express, Farmer**, China Ocean News, Aquatic Weekly, and nearly 500 domestic and foreign professional forums (such as Xinhuanet, China Food Industry Network, China Feed, China Agricultural Information Network, China Aquatic Technology Promotion Network, China Report, 21st Century Network) reported.

Question 1: What kind of fish can fish be polycultured with 10 points.

Question 2: What kind of fish can fish be polycultured with Large upper and middle pelagic fish that are not very aggressive, such as Arowana, daguerreotype, colorful, Bassia, etc.

Question 3: What kind of fish can not be polycultured with fish in general Large upper and middle pelagic fish that are not too aggressive, such as Arowana, daguerreotype, colorful fish, Barcia, etc.

Question 4: What kind of fish can fish be kept with tropical fish? and tropical fish polyculture medium-sized.

Arowana polyculture is the most beautiful.

Golden Dragon. Brazil Yajin. Northern Thai Tigers. Indonesian concerns. Thin wire plates. Thick wire boards, etc.

Arowana, Tiger Fish, Daguerreotype, Parrot, Anchovy, Small Tropical Fish, Queen Opposite Sex (Clean Fish), etc

Question 5: Can monk fish be polycultured with fish It is not recommended to polyculture monk fish with any fish. Although the fish belong to the bottom of the water, the arhat belongs to the middle and upper reaches of the swimming fish, but the arhat belongs to the more aggressive fish, so to a certain extent, it is not recommended to polyculture, in addition to the fish tank is generally relatively large, so the single culture has been relatively empty, and if you raise two, it is undoubtedly fighting!

Question 6: Can fish be raised with Arowana You can raise it without any problems. Fish prefer new water, pay attention to maintain good water quality, I work in the fishing farm, if you have any questions, please ask, thank you!

Question 7: Can colorful angelfish and rainbow fish be polycultured If you're talking about fish, you can! But have you ever thought about it, the colorful is the fish that is admired from the side, and the fish is the fish that is admired at the top, will you look good when you put these two together?

In addition, the fish is too large in size, and the colorful ones are put together, and grabbing food will cause problems! It is recommended to keep them separately, and occasionally enjoy them can be put together!

Question 8: Can redfin crucian carp, fish, and Arowana be polycultured?

Question 9: Can the fish you just bought be polycultured with Arowana, what should be paid attention to is that most of the fish die in the water and cannot be impatient Fish are particularly sensitive to water quality fluctuations.

Question 10: Can fish be polycultured with heterotypic There is absolutely no problem Arowana is a perfect match for any of them Because they are in different areas For example, the fish is the lower layer Arowana is the middle and upper layer So they are basically very harmonious But I remind you that if this is a new invitation, then the size difference between them should not be too big Otherwise, it will be easy to be timid You can go to the top of the Arowana to visit more There are aquarists who are so polycultured I have also raised this.

<>1. Polyculture of monk fish and parrot fish: blood parrot and monk fish should be polycultured from an early age, and it is difficult to mix together once they grow up. Because they are all territorial, they are like fish with strong knowledge.

Mixed together from an early age, it is also necessary to make the blood parrot bigger than the arhat, so that there will be no fighting; If the monk fish is bigger, then it will never tolerate the year-round rental parrot fish!

2. Map fish and parrot fish polyculture: In this way, the fish will grow up quickly and eat more, basically the map fish are not picky eaters and have a relatively mild personality.

3. Polyculture of silver Arowana and parrot fish: Arowana belongs to the middle fish, while parrot fish is active at the bottom of the water, and the polyculture of the two can increase the vitality of the fish tank.

4. Lucky fish and parrot fish polyculture: the meaning is very compatible with parrot fish, the color is good, the black warship is red and black, the contrast is great, especially beautiful, and the warship is one gold and one red, and it is also eye-catching.

5. Polyculture of golden pineapple and parrot fish: The golden pineapple with the same size of the polyculture is very beautiful, and a tank of parrots with two golden pineapples is very beautiful.

6. Seven-star knife and parrot fish polyculture: the black round on both sides of the body is very special, the fish has a mild temperament, if it is polycultured with parrot fish, it is best to choose a larger one, not easy to be bullied.

7. Polyculture of pig-nosed turtles and parrot fish: the image is very cute, and there are occasional biting actions, but the baby turtle is a very clumsy animal and will not cause harm to the responsive parrot fish.

<> polyculture of a variety of fish and specifications in the pond can give full play to the production potential of the pond water body, give full play to the mutually beneficial role of the farmed fish, and make reasonable and economical use of bait. Polyculture not only increases the yield of adult fish, but also cultivates a large number of large-sized fingerlings stocked the following year, reducing costs and improving the efficiency of crowding. Therefore, polyculture is an important technical measure for stable and high yield in ponds, and it is one of the important characteristics of pond fish culture in China.

If polyculture is to be desired, the three-dimensional utilization of ponds should first be considered. That is, the reasonable combination of pelagic fish such as silver carp and bighead carp and pelagic fish such as grass carp and tuantou bream and bottom fish such as carp and crucian carp. Polyculture of these fish in a certain proportion in the same pond can make full use of the various water layers of the pond, increasing the stocking per unit area and fish production.

Secondly, consider the full use of the bait in the pond. For example, grass carp, carp, crucian carp, bream herbivore and artificially fed concentrate feed, the masses call them eating fish. Their residual bait and manure are fertile water, so they provide good bait for filter-feeding fish such as silver carp and bighead carp, so the masses call silver carp and bighead carp as fat water fish.

In turn, the fish in the water fertilizer prevent the pond water from being over-fertilized by filtering plankton and organic detritus, creating good living conditions for the fish that like fresh water. It not only improves the utilization rate of bait, achieves a kind of bait, double utilization, but also plays a mutually beneficial role between them and promotes the growth of fish. Fishing proverbs are:

The saying that one grass raises three silver carp is talking about the biological significance of the polyculture of Kuanzi Mingfeng Sun. Another example is that grass carp has a large individual and a wide range of diets, requiring high quality bait, while carp, crucian carp, bream, etc. are the opposite. Grass carp provide them with a large amount of palatable bait, and carp, crucian carp and bream remove bait residues for grass carp and clean the feeding grounds to prevent the bait from spoiling.

This not only makes full use of the bait, but also improves the water quality, which is conducive to the length of the fish silver chain.

Cyprinidae is a fish of the genus Puntius.

The picture below shows the Rose Puntius Conchonius, commonly known as Rose Thorn Fish, Rose Crucian Carp, Coffee Fish, Indian Crucian Carp.

The body is spindle-shaped, reaching 14-15 cm in wild conditions. The side is flattened, the body of the juvenile fish is silvery-white, as it grows, the back is silvery-white, and the rest of the fish is red, yellow, and green, shining under the sun. There is a black round spot on the back and a black spot on the dorsal fin.

During the breeding period, the marriage color appears, and the male has a rosy red body, which is bright and beautiful. There are two varieties of long tail and short tail, and because of their mild temperament and bright color, they have always enjoyed the reputation of tropical goldfish.

It can withstand 16 low temperatures and adapt to neutral water quality. Like the water body with lush aquatic plants and old water, it is not advisable to change a large amount of water at one time, and it is advisable to change the water regularly and quantitatively. It has a lively temperament and never attacks other species of tropical fish, which is a good breed for polyculture.

Omnivorous, likes to eat animal bait, but does not choose to eat.

You even say that the rose carp doesn't bite other fish? Is it a good breed for polyculture? I'm also convinced, don't believe it, otherwise it's yourself who will be unlucky.

Crucian carp, which can be polycultured with any fish, but should not be kept with carnivorous fish, it may be eaten.

Crucian carp (scientific name: carassius auratus, referred to as crucian carp, commonly known as crucian carp melon seeds, moon carp, soil carp, thin head, carp, cold carp, happy head, crucian carp shell, river carp. [1] It is commonly found in Eurasia and is a common freshwater fish belonging to the genus Cruciaceae of the Cypriniformes subclass of radial-finned fish.

After artificial breeding and selection, crucian carp can produce many new species, such as goldfish, which is an ornamental fish, and the scientific name of the edible wild crucian carp is carassius auratus.

Crucian carp is mainly an omnivorous fish that feeds on plants, and likes to live in clusters. The meat is delicate and has high nutritional value, containing 13 grams of protein and 11 grams of fat per 100 grams of meat, and contains a lot of minerals such as calcium, phosphorus and iron. The medicinal value of crucian carp is very high, its nature is flat and sweet, into the stomach, kidney, has the effect of replenishing deficiency, removing loss, warming the stomach and eating, and replenishing vitality.

Crucian carp is widely distributed, and there is perennial production in waters all over the country, with the crucian carp in February, April and August and December being the fattest, and it is one of the important edible fish in China. [2] The maximum body length is about 30 cm, the habitat depth is 0 20 meters, it is non-toxic, economical edible fish, and it is of good quality and low price. It is mostly produced in the Yellow River Basin, the Yangtze River Basin, and the Pearl River Basin, among which the Erhai crucian carp is more famous.

This is crucian carp, which can be raised with a variety of fish. Except to be able to eat it.

Night Park Niu Zhu Huaigu (Li Bai).

Goldfish are divided into grass fish, culture fish and egg fish.

Generally, it is best to raise each species separately, and if you want to mix it, it is to mix it in the same species.

However, the cephalic tumors and pearls in the literature species can be mixed with the egg seed fish, and the gilt in the literature species can barely be mixed with grass gold and koi, but the body size is best not to be too different.

However, goldfish are not suitable for polyculture with tropical fish for the following reasons:

1 The habits and conditions of care are different between the two types of fish. Tropical fish should be kept in water above 20 degrees Celsius, and goldfish can survive the winter at ambient temperature (i.e., without heating); Once polycultured, the water occupied by the goldfish will also be warmed up, which will increase the electricity bill;

2 Tropical fish are agile and have strong foraging ability, while goldfish are sluggish and weak in foraging ability, coupled with the small amount of tropical fish food, the goldfish eat a large amount of goldfish and polyculture goldfish will not get enough food and will be malnourished;

3 Some tropical fish will chase after the tail, and goldfish are slow to swim and will inevitably be bitten.

4 Aquatic plants in tropical fish tanks can not only increase ornamental but also be more suitable for the life of tropical fish, and goldfish will make it difficult for them to swim and forage in tanks with a large number of aquatic plants;

5 Tropical fish consume less oxygen for respiration, while goldfish consume more oxygen, and polyculture is easy to cause goldfish to die early due to hypoxia.

6 Two types of fish seem to be incongruous when kept together, and there is a strange feeling.
