The cinnamon fish is a warm-water omnivorous fish, the fry have a source, the breeding technology is simple, ingesting with feed, fast growth, high nutritional value, the market is favorable. Suitable for aquaculture in most areas of China, is an excellent species with great prospects for development.

Life habits of the fish for freshwater benthic fish. Survival water temperature 0.5 ~ 41 ℃, suitable for the growth of water temperature of 22 ~ 28 ℃. pH value of 7 ~ 10. Skin with respiratory function, the oxygen content of the water changes in adaptability. The skin has a respiratory function, adaptable to changes in the oxygen content of the water.

3. Diet The fish is omnivorous, feeding on zooplankton, and the fish species and adult fish feed on plant residues and aquatic insect larvae. In the process of artificial cultivation, it can ingest various kinds of matching feeds better. It can concentrate on grabbing food after domestication. The intestine is short and its length is about equal to the body length.

4. Growth Artificial culture of young fish in the year up to 50 ~ 80 grams, 2 years weight up to 300 ~ 500 grams.

5. Breeding The fish is sexually mature at the age of 2 to 3 years, and the males usually mature earlier than the females. It can spawn naturally at a temperature of 20~26℃. The spawning period is from May to July, and the eggs are spawned in batches and then attached to the water plants. 2-3 days after spawning, the fish fry will hatch.

Two, fish breeding

1, pond conditions Breeding pond to 2 to 3 acres is appropriate. The water depth is about 1.5 meters. The water storage is maintained at about 1.2 meters, the pond around the shallow water area has a certain amount of water plants is good. Requirements for injection, drainage is convenient, water quality is fresh, no pollution.

2. Pond disinfection Use conventional methods to disinfect the pond. Use lime 75 kg/mu to disinfect the pond. Organic fertilizer should be applied before stocking. Make sure there is enough plankton as open bait.

3. Fry stocking Fry can be stocked after one week of pond disinfection. The stocking of the dense bank is generally 2 to 3 cm in length, 2500 to 5000 tails / mu. Before the pond with 3 ~ 4% salt water immersion 5 ~ 8 minutes. After three months of cultivation can be obtained full-length 12 ~ 16 cm of large-size fish species.

4. Feeding management The early stage of fish breeding is mainly feeding on zooplankton. Adequate supplementation of artificial feed. In the early stage, some soybean milk should be fed, and in the later stage, after taming the food can be fed with feed, the particle size of the feed should be slightly smaller than the caliber of the fish, the beginning of the available powder or particulate material, and later changed to small particle size material. Feeding amount is about 5% of the fish body volume //www.nczfj.com //, bait placed in the shallow water of the pond, and according to the specific situation. Body length of 5 centimeters or more. Can be tamed with crucian carp matching feed. Crude protein content of 32 ~ 35%, and the implementation of quality, timing, quantitative, positioning feeding. After 3~4 months of feeding, the specification of fish species can reach 30~50g/tail, and the mu yield reaches 150~200kg. Regular fertilization to ensure adequate supply of live bait; timely filling of new water, regular application of photosynthetic bacteria to improve water quality.

Three, pond fish

1. Pond main

①Pond conditions: pond area of 3 to 5 acres, east-west, rectangular. There can be a small amount of submerged plants in the pond, requiring convenient injection and drainage, adequate water supply, good water quality, no pollution.

②Pond disinfection: the conventional method of disinfection, lime 75 kg / mu pond disinfection.

③ fish stocking: one week after the pond disinfection can be put into the fish, advocating early stocking, early food, early growth, generally in the water temperature of about 10 ℃, mu put the body length of 8 ~ 15 cm, 1000 ~ 1500 fish species of crocodile. Before the pond with 3 ~ 4% salt water immersion 5 ~ 8 minutes.

④Feed: Feed 28-32% crude protein compound feed. Before stocking to apply sufficient base fertilizer, according to the water quality, water color during feeding, regular fertilizer, organic fertilizer and inorganic fertilizer can be used in conjunction with the cultivation of sufficient plankton. However, we should pay attention to adjusting the water quality and adding new water at the right time. It is not advisable to mix carp, grass, bighead carp and other fish with fierce competition for food, but silver carp can be mixed in moderation.
