Yellow spicy tench, scientific name yellow catfish, is a freshwater fish that is loved by consumers because of its delicate meat and rich nutrition. In recent years, the yellow and spicy tench aquaculture industry has gradually emerged, becoming an important way for farmers to increase their income and get rich. The following is the cultivation method of yellow and spicy tench::
1. Pond conditions.
Choose a pond with sufficient water source, good water quality, and convenient drainage and irrigation, the pond area is generally 3-5 acres, and the water depth is 1About 5-2 meters. At the bottom of the pond, a layer of sediment about 20 cm thick is laid, and some aquatic plants are planted, such as bitter grass and black algae, to provide a place for the yellow and spicy tench to roost and escape the heat.
2. Stocking of fingerlings.
Before stocking, the pond is disinfected with quicklime or bleach. Select yellow and spicy tench fingerlings with strong physique and neat specifications, and the stocking amount per mu is generally 2000-3000. In order to improve the efficiency of aquaculture, it can be appropriately matched with filter-feeding fish such as silver carp and bighead carp.
3. Feed feeding.
Spicy tench is an omnivorous fish that feeds mainly on zooplankton, benthic animals, aquatic insects, etc. In the breeding process, artificial compound feed, such as soybean cake, vegetable cake, fish meal, etc., can be fed to meet its nutritional needs. The daily feeding amount is 3%-5% of the body weight of the fish, and it is fed in 2-3 times.
4. Water quality management.
Spicy tench likes fresh water, so it needs to be filled with new water regularly to keep the water fresh. In the high temperature season, fill with fresh water every 7-10 days, 20-30 cm each time. At the same time, biological agents are used to regulate water quality, such as photosynthetic bacteria, em bacteria, etc., and reduce the content of harmful substances such as ammonia nitrogen and nitrite.
5. Disease prevention and control.
Yellow and spicy tench has strong disease resistance, but disease prevention still needs to be done. During the cultivation process, quicklime or bleaching powder is regularly used to disinfect the ponds and kill pathogens. Add Chinese herbs or immune boosters to the feed to improve the immunity of the fish. Once a fish disease is detected, it should be prompted**.
Sixth, daily management.
Insist on patrolling the pond every day to observe the feeding, activity and growth of yellow and spicy tench. Regularly check that pond facilities such as aerators, pumps, etc. are functioning properly. Do a good job of breeding records, including feed amount, water quality monitoring data, fish disease occurrence, etc., so as to summarize lessons and lessons in a timely manner.
7. Fishing and listing.
The breeding cycle of yellow and spicy tench is 12-15 months, and it can be caught and marketed when the weight reaches more than 200 grams. Use a net with a large mesh to avoid damage to the fish. The caught yellow and spicy tench should be put into the live fish transport truck in time and transported to the market for sale.
