Common disease of fish-turning Gill
Arowana is a very beautiful ornamental fish, but it is easy to turn the Gill, that is, the software roll at the end of the operculum. Although the disease is not fatal, it affects the appearance of the fish, so it must be treated. The main cause of arowana turning Gill is the problem of water quality, which is often caused by the lack of dissolved oxygen in the water and the difficulty of breathing caused by improper change of water. The solution is to improve the filtration system of the fish tank and increase the dissolved oxygen in the water, and the second is to install a surf pump in the fish tank to increase the flow speed in the fish tank.

The method of improving the resistance of fish
In recent years, with the expansion of aquaculture scale, the improvement of aquaculture production and the deterioration of aquaculture environment, the diseases of farmed aquatic animals are becoming more and more serious, which restricts the improvement of aquaculture production to some extent. At present, under the condition of artificial culture, it is unrealistic to control and eliminate all pathogens. In order to control the occurrence of fish disease, the author thinks that we should first improve the fish resistance, supplemented by drug treatment, the effect will be better. Here are several methods to improve the resistance of fish for reference. Stocking fine varieties is the first choice to improve the resistance of fish.

Due to the water system, fish species should be put in reasonably.
In an activity of science and technology going to the countryside, the author learned that the output and benefit of many fish farmers were not ideal in the process of fish culture in ponds over the years. the main reason is that the fish species are not reasonably matched according to the fish diet and habits, and the species is single, the quantity is too large and the size is small. This situation exists more or less all over the country, and the end of the year and the beginning of the year is the season for the release of a large number of fish fingers. in order to make full use of the water body, put the fish species reasonably and increase the yield per unit area of the water body, the fish species will be put in reasonably according to the water system.

Artificial breeding technique of barracuda
Selection and cultivation of parent fish: among adult fish caught from the sea area or cultured from seawater and brackish water in autumn or early winter, intact individuals are selected as parent fish. The female fish should be 3 years old and weigh more than 1.5 kg, and the male fish should be 2 years old and weigh more than 1 kg. Fish pond area should not be too large, 1500-2000 square meters is appropriate, water depth 1.5-2 meters, there are sea, fresh water sources, convenient drainage and irrigation. The stocking amount per mu of parent fish pond should not exceed 100 kg. The barracuda began to ask for a small amount of food when the water temperature was 4 ℃.

Braised prawns in oil
Main ingredients: fresh prawns (or prawns): 1, cut off the feet of prawns (I am in a hurry, this step is omitted); pinch a piece in the middle of the shrimp tail and carefully draw out the sand line; wash and drain the shrimp; 2, heat the pan, pour in a spoonful of oil, add ginger and saute until fragrant; stir-fry the prawns until half-cooked, cook in cooking wine, add soy sauce sugar and a small amount of water; boil and simmer for a while, then the juice can be filled with plate.

The benefit of mixed culture of fish and lotus root in pond is high.
The technology of mixed culture of fish and lotus root in the format pond is to divide the hardened lotus root pond into small squares of 2 square meters and 4 square meters, with an average yield of 5000 kg per mu of water surface, 400 kg of fish and 450 kg of fish, with a net benefit of more than 10, 000 yuan per mu. This technology can make use of barren pits, barren beaches, river beaches and scattered corners to build mixed culture of pond fish and lotus root, which has the characteristics of small investment, low cost, quick effect and high benefit, so it is suitable for the development of thousands of rural families and has a very broad prospect of popularization.

The scale culture of Pelteobagrus fulvidraco is difficult and the effect of mixed culture is good.
Pelteobagrus fulvidraco is a benthic omnivorous fish with delicate meat, rich nutrition and high economic value, so it is a cultured species with great market potential. Pelteobagrus fulvidraco has strong adaptability and its growth rate is slower than that of cyprinid fish, but it grows faster for the species itself. the fry propagated in that year can meet the commercial specifications, and the population yield is higher. At present, there are some difficulties in large-scale artificial culture, so it is imperative to carry out mixed culture. Mixed culture of Pelteobagrus fulvidraco in fishing ponds has the following advantages: first, it can feed on small miscellaneous fish and shrimps of low value in the pond.

Rescue of ammonia nitrogen poisoning in pond fish
Pellet feed is used to feed carp, grass carp, mackerel, white Pomfret, crucian carp, etc., due to a large amount of feeding, feces and leftovers increase, the nitrogenous substances produced by protein decomposition increase, a little carelessly, these fish will have ammonia nitrogen poisoning, light will affect normal growth, serious will cause the death of fish. The identification and rescue methods of ammonia nitrogen poisoning in pond fish are introduced as follows. 1. Identification of poisoning. 1. Occurrence characteristics.

Feeding of grass silver carp and bighead carp in autumn and winter
The breeding of parent fish is an important link in the artificial reproduction of green, grass, silver carp and bighead carp. The feeding and management in autumn and winter directly affects the effect of spawning in the second year, so full attention must be paid to it. 1. Conditions and cleaning of fish ponds. The fish ponds for breeding parent fish should not only be close to the spawning pond but also have good water source conditions, and it is convenient for irrigation and drainage. The bottom of the pond is less silt, silver carp and bighead carp ponds with a depth of 20 centimeters is enough, green and grass carp ponds should contain little or no silt. The area is 2000,3300 square meters and the water depth is about 1.5 meters. Parent fish cultivation

The benefit of mountain bee domestication is high.
Mountain wasp is a kind of wild economic insect. The honey it collects from natural flowers is the best honey. The market price can reach 30 RMB40 per kilogram. Generally, each barrel of mountain bees can get about 25 kilograms of honey a year, such as strong bees, good honey sources and suitable climate. Each group of bees can produce 40 kilograms of honey. At present, it is the peak period for mountain bees to be grouped, and bringing mountain bees home for breeding is a good project with less investment and quick results. The manufacture and placement of a bee bucket consists of a bottom bucket, a relay bucket, a bottom bucket, and a bucket.
