Mandarin fish artificial advance propagation method

Abstract

The invention discloses a mandarin fish advanced artificial propagation method. The method comprises (1) selecting parent fish, (2) breeding parent fish, (3) artificial uteracon, (4) hatching, (5) breeding scrod, (6) breeding mating baitfish. Artificial breeding the parent fish in warmhouse originally, making the gonadal advance mature and reducing the reproductive cycle of the mandarin fish and getting the goal of breeding and sales in a same year and processing important social benefit and economic benefit using the technology of adjusting and controlling water temperature. During the breeding of mandarin scrod fish, early maturing breeding the soft-shelled turtle parent fish and advanced done artificial propagation to solve the problem of mating shedding bait fish for the scrod of the mandarin fish; providing mandarin fish with sufficient bait fish using the natural breeding of thecrucian in normal temperature condition.

Description

technical field [0001] The invention relates to a method for early artificial propagation of mandarin fish. Background technique [0002] Mandarin fish (Siniperca chuatsi), also known as sweet-scented osmanthus fish and seasonal flower fish, belongs to Perciformes, Perciformes, family, Siniperca genus. Mandarin fish is shaped like a perch in Songjiang River, with thorns on its wings. It is a rare freshwater economically farmed fish in my country. It has delicious meat, rich nutrition, high protein and various amino acids, and has medicinal functions. It has high economic value. In the Qing Dynasty, Zhang Zhihe had a poem of "peach blossoms and flowing water with mandarin fish fat", which is favored by consumers and has a broad market prospect. At the same time, with the need for species renewal and structural adjustment in the aquaculture industry, mandarin fish farming as a special aquatic product has also developed rapidly, and the aquaculture area has continued to incre...

Problems solved by technology

However, due to the constraints of factors such as geographical location and climate, the artificial breeding of anchovies under normal temperature conditions in this area can only be carried out in the first ten days of May, which affects the growth period of the year and prolongs the breeding cycle for growing into the market. It is not conducive to the improvement of production and efficiency; and the seedlings introduced from the south, due to long-term breeding and do not pay attention to the purification and rejuvenation of germplasm, coupled with the influence of climatic conditions, transportation and other factors, the risk of breeding is getting higher and higher , has seriously affected the healthy and rapid development of the mandarin fish aquaculture industry
