The culture technology of black spot pike, "the oldest fish in the world"!

Pike, also known as black spot pike, is a common freshwater fish, and it is also the most brutal carnivorous fish among all freshwater fish. Pike grows fast, the meat is fresh and refreshing, the taste is not strong, and its edible value is very high. Here is an introduction to the culture technology of black spot pike, the oldest fish in the world!

First, pond preparation

Before breeding pike, we should first prepare the breeding pond, control the pond area according to the breeding quantity, generally about 6-7 mu, the depth is more than 2m, ensure that the water source is sufficient, have good drainage and irrigation capacity, and be able to adjust the water temperature normally. Then carry on the thorough disinfection to the pond, sprinkle the appropriate amount of soybean milk into the pond about 3 days before breeding, and increase the biological feed in the pond. Then put water lotus and other plants on the pond for its shade, plant an appropriate amount of water plants as a hiding place for pike, and place pike to kill each other.

Second, feed preparation

Pike is a kind of carnivorous fish, so the main bait is small fish, so we should put sufficient bait fish in the pond before releasing pike fry, the length of bait fish should be kept at about 5cm, it is best to cultivate it in the original pond, but before stocking, bait fish should be disinfected to prevent bacteria from entering the pond and affect the growth of pike, and then appropriate fertilization to cultivate bait fish. The bait fish are mainly carp, silver carp and so on. When the bait fish grows to about 5, then put in the dogfish fry of the same growth specification.

III. Nurturance management

With the growth time of pike getting longer and longer, the palatability of pike to bait fish becomes more and more strict, and each time the food intake will gradually increase, so we should reasonably adjust the feeding frequency and dosage according to the growth progress of pike. And we should pay attention to separate breeding treatment once a month, put the same specifications together, to prevent pikes from killing each other, and the bad phenomenon of eating big and small, strong eating and weak eating occurs. Then, under adequate and healthy feed and normal management, the body weight of the pike can reach about 1kg by the end of the year, reaching the market standard and can be caught at the right time.

IV. Disease prevention and control

The growth ability of pike is strong, in general, it will not occur, and the incidence rate is low, but artificial breeding will reduce the disease resistance of pike. We must do a good job in management when we breed. Pike is very prone to Gill rot disease if it is not managed properly. Gill rot disease will seriously hinder the breathing of pike, resulting in anoxic death in the later stage of pike. We should keep the water quality good, clean, pollution-free and cool in the process of breeding. To create a good growth environment for pike, after the disease, we should timely sprinkle Youchujing and other agents to the pond for disinfection and prevention, so as to avoid the expansion of the disease.

The above is a brief introduction of pike culture technology by Tuliu. pike is divided into white spot pike and black spot pike, this method is mainly suitable for black spot pike, the management in the process of culture is very important, we must pay more attention to avoid some unnecessary losses.
