example 1

[0054] Select broodstock with strong physique, normal body shape, no sickness, disability, and no deformity for stocking. The stocking density is 50-300kg / mu. The ratio is 1:1.

[0055] 4. Feed and feeding

[0056] The roundmouth copperfish is an omnivorous fish that lives at the bottom of the camp and is mainly animal, providing necessary nutrition.

[0057] The average bait coefficient of roundmouth copperfish is 2.5-4.45.

[0058] 5. Observation of temperature-controlled ponds in 2014 (A-3# pond\A-4# pond\A-9# pond\A-12# pond\A-13# pond\B-6# pond) 6, 7, 8 The daily maximum water temperature of the month, and the pond without temperature control (A-11# pond\A-10# pond\A-7# pond\A-14# pond\A-15# pond\B-7# pond\C- 2# pond) compared with the daily maximum water temperature in the same period. Statistics show that the temperature-controlled pond effectively reduced the daily maximum water temperature in June, July and August, and significantly reduced the monthly variation. ...

Abstract

An artificial breeding method for roundmouth copperfish includes the establishment of key ecological factors in an ecological pond. The key ecological factors in the ecological pond include the control range of 10-100 mg / L for cultivating phytoplankton, the control range for cultivating zooplankton 3-10 mg / L, and the control range for water temperature. ≤32℃, dissolved oxygen control range 3-20mg / L, ammonia nitrogen control range ≤0.6mg / L, transparency control range 50-100cm, stocking density control range 50-300kg / mu. The advantage of the present invention is that, by regulating the key ecological factors of the ecological pond, the probability of outbreak of fatal infectious diseases in the process of artificial cultivation of the copperfish is reduced, and the artificial cultivation of the copperfish is realized, and the survival rate of the cultivation reaches more than 80%. Thereby changed mainly relying on medicine to treat fatal infectious disease method in the existing copperfish breeding process, the existing mainly to cure is changed to be based on prevention of the patent of the present invention.

Description

technical field [0001] The patent of the present invention belongs to the artificial breeding technology, specifically a new artificial breeding method of the round-mouthed copperfish. [0002] technical background [0003] Round-mouthed copperfish (Coreius guichenoti), belonging to Osteichthyes, Cypriniformes, Cyprinidae, Gobioninae, Coreius, also known as water dense, square Tou, Feituo, mahua fish are mainly distributed in the upper and middle reaches of the Yangtze River, the lower reaches of the Jinsha River, and the tributaries of the Minjiang River, Jialing River, and Wujiang River. The roundmouth copperfish is a bottom fish, omnivorous, and feeds on aquatic insects, molluscs, plant fragments, fish eggs, fry, etc. The largest individual can reach 4 kg. It is a rare and unique fish in the Yangtze River with high nutritional value, and it is also the main economic fish in the upper and middle reaches of the Yangtze River. [0004] In recent years, due to various reason...
