Culture techniques of white spot pike

White spot pike is a species of pike, which has a wide range of distribution in China, mainly concentrated in rivers and lakes with vegetation. Is a world-famous fishing fish, white spot pike meat is very fresh and tender, taste good, less fishbone, and fishy taste is not big, is a lot of favorite fish. So how to raise white spot pike? The following editor brings you the culture technology of white spot pike, let's have a look!

1. Pond preparation

White spot pike has strong growth ability, can be listed on the market in the same year, and the diet of white spot pike is very wide, and the small fish of almost all fish can be used as bait for white spot pike. First of all, fish ponds should be prepared before aquaculture. If it is the first time, it is necessary to control the area of fish ponds, which should not exceed 5 mu to avoid failure. Then the thickness of the mud at the bottom of the fish pond should be controlled at about 12 cm, and the water level of the pond should not exceed 3 meters. Ensure that there are adequate, clean and pollution-free water sources, normal drainage and irrigation, water quality in line with breeding standards, and then equipped with oxygen-increasing equipment.

2. Seedling release preparation

About half a month before seedling release, all the water in the pond should be discharged, and then appropriate amount of quicklime should be sprinkled in the pond to disinfect and sterilize the pond. Eliminate germs and other harmful substances in the pond and sun them for about 3 days. Then apply sufficient mature farm manure, add water to about 70 cm, and cultivate plankton bait. And before releasing the white spot pike fry, it is necessary to cultivate sufficient bait fish in the pond to meet the bait needs of the white spot pike. Usually an adult white spot pike eats as much as its body weight every day, so it is necessary to ensure that there is sufficient food.

3. Cultivate bait fish

When we culture, we should reasonably adjust the feeding of bait fish according to the food intake and meat habits of white spot pike. The food intake of white spot pike varies with the increase of growth time and the change of body weight. Therefore, in order to prevent the white spot pike from killing each other due to the lack of bait in its growth, we must cultivate enough bait fish before stocking. Then feed the food by the method of self-cultivation and purchase. In the process of cultivation, it is necessary to do a good job of disinfection to prevent the existence of diseased fish and affect the growth of white spot pike.

4. Water quality regulation

White spot pike likes to grow in clean and hygienic water with sufficient dissolved oxygen and warm water. When we culture, we should pay attention to observe the change of water temperature and the growth of fish and add water properly to deepen the water level of the pond to about 2 meters. When it is hot in summer, add clean cold water properly, keep the transparency of the pool water, and adjust the water temperature properly. Then use the relevant agents to regulate the water quality, once every half a month, lasting about 3 months. In addition, the water quality should be adjusted according to the changes of water quality. Pay attention to observe the content of dissolved oxygen in water and increase oxygen in time when it is insufficient.

The above is a brief introduction of white spot pike culture technology, white spot pike culture is relatively simple, but we need careful management, do a good job of basic work, in order to ensure the healthy growth of white spot pike and increase production. That's all for today's introduction. This article is for reference only. I hope it can help you all.
