Improve the water color of eel pond
In the process of culture, the water color of the pond is changeable, indicating that a large number of phytoplankton died, rotifers, water fleas and other zooplankton increased sharply, dissolved oxygen and PH decreased, harmful gas increased, eel feeding decreased, floating head appeared, resulting in disease and death. The improvement methods are as follows: 1. Light green becomes transparent: this phenomenon is mass reproduction of zooplankton rotifers and water fleas. Trichlorfon 0.5 ppm plus potassium permanganate 2ppm can be used to kill too many rotifers and water fleas, or to change a large number of water. Stocking more than 500 grams of bighead carp per mu

Adhere to the "Siding" bait to raise high-quality fish
Quality is required to feed the bait to be fresh and palatable, non-decay, good nutrients, easy to be digested and absorbed by fish. Grasses should be sterilized, manure should be fermented, and hard and coarse fodder should be chopped or processed. The monthly feeding quantity should be determined according to the water temperature, fish growth and feed supply. The daily feeding amount depends on the season, water color, weather and fish intake, which is generally calculated as 2% or 5% of the fish stock in the pond. It can also depend on the eating condition of the fish, such as throwing grass at 8: 9 a.m.

Don't get hurt when fishing in low temperature season.
Under the influence of the traditional culture mode in our country, the low temperature season is the main period of fishing, or the adult fish will be caught on the market at this time, or the fish species will be released at this time. Whether the fishing method is correct or not has a certain impact on the next step of aquaculture. Improper fishing can easily lead to the occurrence of fish diseases. In order to ensure the smooth progress of the next step of aquaculture, attention should be paid to the following problems: before fishing, we should pay attention to removing debris around the pond and in the pond, such as branches, weeds, etc., in order to ensure that the net is pulled.

Comprehensive utilization of waste materials from fish processing
The remaining fish head, fish tail, minced meat, scales, skin, viscera, bone, gallbladder and so on, contain a lot of protein, amino acids, trace elements and vitamins. Using these protein resources, a variety of deep processing products can be made, including soluble edible fish protein meal, liquid fish protein feed, fish scale glue, fish skin glue, bone paste, fish protein calcium sugar, bile pigment calcium salt and bile salt, etc. Comprehensive utilization of fish processing waste can reduce the cost of leading products, increase the added value of aquatic products, maintain the environment, reduce the discharge of waste water and waste.

Breeding technique of koi
Because of their large size, koi usually breed in ponds. Brocade carp egg band sticky, fertilized eggs adhere to water plants and other attachments to develop, so artificial fish nests must be placed in the pool where brocade carps are bred. In order to increase production, artificial reproduction can be carried out to cultivate fish fry. It is relatively easy to distinguish between male and female, from the body shape, such as abdominal hypertrophy for female fish, thin elderly for male fish; from the anal point of view, female anus is wide and flat, male anus is small, concave. In the stage of sexual maturity, you can check whether there is a "chasing star" on the edge of the pectoral fin and caress it with your hand.

Reproduction of swordtail fish
Swordtail fish are oviparous fishes. The swordtail fish has a strong fecundity. At the age of 6-8 months, the male fish begins to chase the female fish and mate with the female fish to complete in vivo fertilization. The fertilized eggs hatch into larvae in the female and are excluded from the body. Swordtail fish are easy to breed and need no special management. When breeding, choose more than 5 centimeters of fish, the female-to-male ratio of 1:1 or 2:1 is appropriate, the bottom of the cylinder covered with some soft leaves of water plants, feed enough bait.
