Rapid breeding techniques of Fish fingerling in Summer
Summer is a very important season for fish breeding. Good cultivation measures can promote growth, enhance physique, improve disease resistance, provide excellent species with large size and strong physique for adult fish culture, and increase production, income and efficiency. Summing up the experience in recent years, the rapid cultivation of fish species in summer should do the following: first, regulate the water environment. As the saying goes, "Fish culture first raises water, water makes fish fry strong." In the ponds where fish species were cultivated in the past, due to the accumulation of silt after long-term culture, the water quality gradually aged, deteriorated and dissolved oxygen.

What is the relationship between the culture of the four major domestic fish and meteorological conditions
Fish live in water, but it is also closely related to meteorological conditions. Temperature fish is a variable temperature animal, the water temperature is the body temperature, the water temperature directly affects the metabolic activity of life, the optimum temperature range is 10 to 33 degrees Celsius, the optimum temperature is 25 to 30 degrees Celsius, the optimum temperature is 25 to 30 degrees Celsius, and the dormancy begins below 10 degrees Celsius. Slow growth, increased appetite at 15 to 20 degrees Celsius, fast growth, the fastest growth at 20 to 30 degrees Celsius, and slow growth above 30 degrees Celsius, so bait intake should be paid attention to.

Technique of mixed culture of turtle, crab, shrimp and fish
1. Pond conditions: the pond area is 3.5 mu, the bottom is flat, the silt is about 15 cm thick and the water depth is 1.5 meters. The pond is surrounded by a 40-centimeter-wide glass fence equipped with a 1.5 kilowatt water wheel aerator. 2. Clean the pond with fertilizer and water: dry clear the pond with 75 kilograms of quicklime per mu and expose it to the sun for 5 days. One week before seedling release, the water was 80 cm deep, and Feishuibao and EM were used to enrich the water quality, so that the transparency of the water was about 30 cm, and the water color was tan or yellowish green. 3 、

Experience in the treatment of enteritis in fish
In the process of aquaculture (especially in the large-scale cultivation of allogynogenetic silver crucian carp in the coastal tidal flat of northern Jiangsu), mariculturists often encounter the problem of slow growth or non-growth of their farmed fish. Through the detection of various water quality indexes (pH value, dissolved oxygen, ammonia nitrogen, nitrite nitrogen, hydrogen sulfide, etc.) in the water environment of the culture site, all of them are in line with the standard of culture water, and for the body detection and microscopic examination of cultured fish, no parasites were found on the Gill and body surface. There are no abnormal symptoms in the anus, but light pressure on the abdomen or "gelatinous feces"

Selection and conservation of carp species
Any good variety, if not pay attention to seed selection and seed conservation work, often will cause seed quality degradation, yield decline and other traits worse. Jian carp has stable genetic characters and can pass on the excellent dangerous state of this breed to the offspring through self-population breeding. However, different carp breeds are easy to mate and mix with each other, and there are differences among individuals of the same breed. Living environment will also have a greater impact on the traits of the breed. Therefore, we must pay attention to the breeding of improved varieties, according to the variety index, select the fish with good characteristics as parent fish breeding, and let them reproduce.

Effective measures to prevent floating head of fish
Discharge an appropriate amount of pond water and inject new water, and the suitable time for adding water is about 2-3 o'clock in the afternoon. Rational use of aerator, stop fertilization, control the eating of fish. Sprinkle a small amount of quicklime water many times to regulate the pH of the water body. Chlorine dioxide was used twice to disinfect the water body, and an appropriate amount of oxygenator and microecological preparation could be applied before disinfection.

How to raise shrimp well in midsummer
In the high temperature season in midsummer, hot weather, strong light, high water temperature and poor water quality affect the foraging and molting growth of shrimp, which can easily lead to disease and death of shrimp. Farmers should do a good job in the following management work in the high temperature season: with the increase of water temperature and the growth of shrimp, the water depth should be continuously increased, especially in the middle and later stages of culture, the water level must be increased to 1.8m~2m, and the high temperature period should be kept above 2.2m. During the high temperature period, full drainage and full irrigation should be carried out, and the water temperature should be controlled within 30 ℃, so that the transparency of the water can reach 35cm.

Processing Technology of Shrimp skin
Main raw materials: hairy shrimp, salt and so on. Equipment: iron pot, basket, running water stove. Production method: the hairy shrimp are graded and selected, and those containing a lot of sundries should be screened with a sieve. If the raw material is not clean, wash it and put it in a basket to drain water. Each basket contains about 6 kilograms of hairy shrimp. Can be cooked in the following ways: ① basket cooking method. That is, fill a large iron pot with a diameter of 90 cm with seven minutes of fresh water, add 2 kilograms of salt, boil, and sprinkle the shrimp baskets after draining with appropriate amount of salt (according to special-grade hairy shrimps every 50 grams).

Natural reproduction of koi
The selection of good parent fish is the key to the reproduction of koi. To adopt natural reproduction, we must first choose the parent fish that meet the standard. In the north, after spending the winter indoors, koi, formerly reserved as a species of fish, moved to outdoor fish ponds in mid-late March. At this time, parent fish should be further selected to obtain excellent offspring. (1) the selection of parent fish for breeding should generally have the following: strong physique, bright color, pure Lu system, obvious species characteristics, clear edge of color spots, no false edges, no defects, and smooth scales.

What to do when processing fish
When processing fish, do not break the liner. Because the bile is extremely bitter, it will make the meat very bitter when contaminated with it. No matter how much it is washed and seasoned, it will not help. Moreover, the bitter bile of fish contains slight poison, which will not be eliminated even after high temperature. What if you break the gall bladder? Apply wine, baking soda or baking powder to contaminated meat to dissolve bile and rinse with cold water to eliminate bitterness
