Problems solved by technology

However, since mandarin fish feed on live bait fish for life, the traditional fish species cultivated by the four major carp, carp, crucian carp, and round-headed bream cannot effectively guarantee the supply, especially in the middle and late stages of the mandarin fish's vigorous growth period, often due to the supply of bait fish. The unpalatable and insufficient amount of these species lead to low aquaculture yield and decreased breeding benefits, which have seriously affected the healthy development of the mandarin fish aquaculture industrialization process. A new breeding object and supporting technology for breeding in the middle and late stages

Embodiment

[0027] Embodiment: a kind of dace is used as the high-yield breeding method of mandarin fish live bait fish, comprises the following steps:

[0028] 1. Summer flower cultivation According to the morphological characteristics of dace larvae, when the yolk sac disappears, they are put into ponds to cultivate summer flower juveniles.

[0029] 2. Fish fingerlings are cultivated to ensure the supply of bait fish in the middle and late stages of the mandarin fish culture process and improve the utilization rate of pond culture output. When cultivating fish fingerlings, one crop in one pond, two crops in one pond, and three crops in one pond are carried out. technology craft.

[0030] ① One pond one crop method: The pond can be used for other purposes before July. At the end of July, 20,000 to 40,000 dace summer flowers with a size of about 5,000 / kg can be stocked per mu, and dry ponds can be caught at the end of September and early October, and the fish species can be cultivated at...

Description

technical field [0001] The invention relates to a method for high-yield breeding of dace (mudta lusta, dace merigal) as live bait fish for mandarin fish. Background technique [0002] Mandarin fish (Siniperca chuatsi), also known as sweet-scented osmanthus fish and seasonal flower fish, belongs to the order Perciformes, the family Siniperca, and the genus Siniperca. Mandarin fish is shaped like Songjiang perch, with spines on its wings. It is a kind of rare freshwater economically farmed fish in my country. It has delicious meat, rich nutrition, high protein and various amino acids, has medicinal functions, and has high economic value. Zhang Zhihe in the Qing Dynasty had a poem "peach blossoms and flowing water mandarin fish fat", which made the mandarin fish delicious and tender through the ages, and was favored by consumers. The market prospect is broad. increase. However, since mandarin fish feed on live bait fish for life, the traditional fish species cultivated by the...
