1, pond construction
The size of the pond is 50- 100_ and the depth is 50cm. It is necessary to have good drainage and water storage capacity, sufficient water sources and clean and fresh water quality. After selecting the pond, check the wall of the pond and tamp it in time if there is any water leakage. There should be 10cm deep silt at the bottom of the pond. The whole farm is fenced with asbestos or barbed wire to prevent escape.
2, pond disinfection
Dig the mud at the bottom of the pond, then expose it to the sun for about a month, and then disinfect the pond with quicklime. After doing this, the fermented organic fertilizer and biological fertilizer were buried in the pond in order to create a good living environment for the golden loach.
Step 3 put in seedlings
There should not be too much golden loach in the pond, and the amount should be appropriate. Raising too many loaches together will make them sick and spread quickly, resulting in a large number of deaths. If the loach seedlings released is about 3cm, then 0. 1-0.2 kg loach can be released per square meter. In the later breeding process, as the golden loach grows better and better, it is necessary to reduce the breeding density in time, which can reduce the damage between loaches and increase it to a certain extent.
4. Water temperature requirements
The water temperature of golden loach is kept at 15-30℃. If the temperature is too high, you can add water to cool it down. If it is lower than 15℃, it is easy to frostbite loach. In order to keep the water clear, shading measures should be taken at ordinary times, and some duckweeds or water hyacinths can be planted in the water.
Step 5 feed
Golden loach is an omnivore and can eat anything, so in the process of breeding, young loach should try to feed some cladocera such as algae or red worms. When golden loach grows up, it can be fed with artificial feed, algae, fish meal, animal offal, miscellaneous grains and so on. The bait can be replaced properly to keep up with its nutrition.
