Astragalus is highly profitable for culturing loach, and its breeding techniques are as follows:
1. Set up astragalus and loach breeding ponds.
For breeding ponds with yellow muddy loach, we must choose places where they can shelter from the sun, have a quiet environment, and have convenient water sources. Cement ponds and earthen ponds can be used, and cages can also be used in reservoirs, ponds, gutters, and rivers. The area is generally 20 to 100 square meters, too big to manage. If the cement pond is used to raise the yellow muddy loach, it must be dealt with alkali before putting on the seedlings; if the earthen pond is used to raise the yellow muddy loach, it is required that the soil quality is hard and the bottom of the pool shall be compacted. The shape of the rearing pond is determined by the topography. The square can be round, and the pool is 0.7 to 1 meter deep. Whether it is a cement pond or an earth pond, it must be filled with a mud layer at the bottom of the pond and be 30 centimeters thick. The more organic fertilizer is better, and it is good for the yellow locust and loach to dig caves. When building the pool, pay attention to the installation of the inlet, overflow bar nets, to prevent jaundice and loach escape. About 10 days before transplanting, the plants were thoroughly disinfected with quick lime, and the pool water was drained 3 to 4 days before the emergence of the seedlings to inject fresh water.
2. Select the loach seedlings.
The success of breeding yellow trout and loach, seedlings is the key. The seedlings of Astragalus are best cultivated artificially by domesticated deep yellow or large golden spotted nymphs, and can not use variegated seedlings or domesticated seedlings. The seedlings of Scutellaria baicalensis should be 50 to 80 tails per kilogram, which is too small for feeding and the survival rate is low. Stocking density is generally suitable for 1 to 1.5 kilograms per m2 of seedlings, and 20 days after the eel has been stocked, the eel seedlings are placed at the ratio of 1:10. The best survival rate for the loach is artificially cultivated.
3. Feed the compound feed.
First, install the feed table. The feed table will be made of wood or plastic. The area will be set according to the size of the pond and it will be 5 cm below the water surface. The first three days after the release of Astragalus seedlings, do not feed, let the Astragalus adapted to the environment, and feed the feed from the fourth day. It is best to feed the feed at around 7:00 pm every day. At this time, the feed intake of Scutellaria baicalensis is the highest. Artificial rearing of jaundice is mainly based on feed, and some pupa, locust, and mealworm are properly fed. Artificially domesticated yellow quail, compound feed and earthworms are their favorite feeds. Formulated feeds can also be self-aligned, formulated as: fishmeal 21â„2, cakes 1919, energy feed 37?, 蚯蚓12?, minerals 1?, yeast 5?, multivitamin 2?, binder 3?. The artificially-cultivated deep yellow giant catfish seedlings were fed with compound feed. The feed amount was 3 to 5, depending on the weight of the jaundice, and they were fed 1 to 2 times a day. The principle of timing and ration was used to feed 20 kilograms. The seedlings of Scutellaria baicalensis can grow to 200-300 grams a year, which has high breeding efficiency. Mudworms mainly feed on the excrement of jaundice and the uneaten scutellaria feed in ponds. Loach naturally breeds quickly. When the proportion of muddy ponds is greater than 1:10, bran can be fed once a day.
4. Feeding and management of loachy loach.
The growth season is from April to November, including the peak season from May to September. During this period, the management needs to be "difficult" and "fine", that is, diligent patrol pool and ground management, and find that the problem is solved quickly. Observe carefully the growth status of the jaundice and mud in the pond so that appropriate measures can be taken in time. The habit of jaundice and loach is nocturnal. Keep the water in the pool fresh, with a pH of 6. The water level is suitable.
5. The rickets are mainly prevention.
Once the onset of jaundice, the treatment effect is often unsatisfactory. Must be disease-free, disease-prevented, and anti-pregnant. Can not rely on the saying that "Huang Biao is not sick". Always use a concentration of 1-2 bleach Quanchiposa, regularly with copper sulfate drugs to prevent disease.
