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
Existing single-type fish fertilizers and compound-type fish fertilizers also have a common shortcoming, that is, they cannot kill harmful bacteria and insects, so they lack the effect of effectively preventing and controlling fish diseases
The microbial compound fish fertilizer can increase the content of beneficial bacteria in fish ponds and effectively reduce the occurrence of fish diseases. At present, there is no report on the special use of this compound microbial fish fertilizer

Embodiment 1

[0020] A method for cultivating sweet-scented osmanthus fish utilizing microbial feed, comprising the following steps:

[0021] 1) Pond construction: The pond requires a sandy bottom, silt of about 15cm, water depth of more than 1.5m, convenient drainage and irrigation, good water quality, no sewage inflow, and a small amount of submerged aquatic plants. The depth of the pond should be dug around 30-40cm A circle of shallow ditch to facilitate the fishing of this fish; use quicklime or bleaching powder to disinfect the whole pond, the amount of quicklime is 150 kg / km 2 ~200kg / km 2 , Bleach powder 15kg / km 2 , After the disinfection is completed, the pond enters the water, and the water quality is too transparent. Inorganic fertilizer or fermented organic fertilizer can be used to fertilize the water to cultivate the basic biological bait in the water. The dosage: inorganic fertilizer 3 kg / km 2 ~5kg / km 2 , organic fertilizer 30kg / km 2 ~50kg / km 2 ;

[0022]2) Environment...

Embodiment 2

[0030] The preparation method is the same as in Example 1.

[0031] In the sweet-scented osmanthus fish juvenile stage of growth, fish out, divide and raise in the middle of five pools, every pond 500, in four pools, throw in respectively the microbial sweet-scented osmanthus manure fertilizer of the embodiment of the present invention 1 and Ordinary sweet-scented osmanthus fish fat (control 1, produced in Beijing Century Arms Biotechnology Co., Ltd. ), and the other pond was not fed with osmanthus fish fertilizer (comparison 2), but put in the same amount of common fish food, the rest of the feed was the same, and the cultivation environment was the same. After 2-4 months of breeding, its output was compared with that of osmanthus fish Growth status, specifically as shown in Table 1 and Table 2:

[0033]

[0034] Through the comparison of table 1 and table 2, it can be found that adding the compound microbial fertilizer of the present inventi...

Abstract

Disclosed is a method for breeding mandarin fish by utilizing microorganic feed. The method includes that: a pond is built; the pond requires a sandy bottom, about 15cm of sludge in depth, deeper than 1.5m of water, convenient irrigation and drainage, good water quality and no sewage inflow; environment requires: parent fish are selected at the most suitable growing water temperature which is 25-29 DEG C in artificial breeding application; in winter and spring, the parent fish healthy in physique and woundless in body surfaces are captured from a breeding pond and put into the pond in a greenhouse for artificial reproduction; the parent fish are put into the pond in the greenhouse for cultivation, and during daily breeding management, in the breeding period, the feed is put for 4 times every day, the amount of the feed is calculated according to 25-50% of the weight of the fish, and the feeding degree is determined according to the fact that no fish competes for food and is flexibly mastered according to weather conditions. Due to the addition of the compound microorganic feed, quick growth of the mandarin fish can be facilitated, EPA (eicosapentaenoic acid) content is increased, illness of the mandarin fish is decreased, the mandarin fish died of disease are decreased, beneficial microorganisms in water are increased, and quality and mass are increased finally.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a method for cultivating sweet-scented osmanthus fish with microbial feed. Background technique [0002] Mandarin fish (Siniperca chuatsi), also known as sweet-scented osmanthus fish and seasonal flower fish, belongs to Perciformes, Perciformes, Siniperca, and 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 develo...
