Problems solved by technology

At present, in northern Anhui, some farmers have not mastered the artificial breeding method of Brazilian sea bream. The fish species are purchased from other places, but the fish species are prone to a large number of deaths during the transportation process, which has caused huge damage to the farmers. Economic losses

Abstract

The invention discloses a Brazilian bream artificial breeding method, and the method comprises the steps of (1) putting 20 healthy male bream and 50 healthy female bream in an oviposition pool; (2) during the oviposition period, feeding an egg promoter in the oviposition pool by three times a day in the day amount of 4-5kg egg promoter; (3) taking out the oosperm floating on the water surface with a 400-mesh nylon net, and putting the oosperm in a hatching barrel after cleaning for hatching; (4) controlling the hatching temperature, namely controlling a hatching water temperature between 20-22 DEG C from 0 to 5 hours in the hatching period, controlling the water temperature between 28-30 DEG C from 6-15 hours, and controlling the water temperature between 25-27 DEG C 15 hours thereafter; (5) controlling illumination, namely employing green light irritation for 80-100 min 10hours after hatching, and the green light intensity is 90-100 lx. According to the Brazilian bream artificial breeding method, the Brazilian bream oviposition amount can be raised by about 10%; the hatching survival rate can be raised by about 8%; also, the operation is easy and practical; and great economic benefit can be obtained.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an artificial propagation method of Brazilian sea bream. Background technique [0002] The scientific name of the Brazilian sea bream is small-mouthed carp, which belongs to Cyprinidae and the genus Carp. It is a new species of freshwater culture introduced from Brazil in 1998 in my country. The fish has strong adaptability, wide feeding habits, fast growth, few diseases, easy to catch, tender meat, high economic value, and has a good promotion prospect. Brazilian sea bream is a hot water fish, living in the bottom of the water body. It is flat on the side, similar to carp and crucian carp, with silvery white body color and fork-shaped tail. Low requirements, low oxygen resistance, the best water temperature is 26-30 ℃. At present, in northern Anhui, some farmers have not mastered the artificial breeding method of Brazilian sea bream. The fish species are purchased from o...
