Embodiment 1

[0030] Embodiment 1: cultivate loach seed according to the following steps

[0031] Step 1: First-level cultivation

[0032] (1) Cultivation of bait organisms: loach open bait cultivation pool 40m 2 10 days before the loach water flower is stocked, use 0.5ppm chlorine dioxide liquid medicine to clear the pond of the loach opening bait cultivation pond, inject water and fertilize after 2 days; apply fermented chicken manure 400kg per mu, stir the bottom of the pond once every 1d; Sprinkle decomposed and fermented chicken manure twice, 50kg per mu each time; sprinkle EM bacteria once a week; if it is found that the density of rotifers per milliliter of pond water is less than 40 during the cultivation of bait organisms, then sprinkle soybean milk (per mu, 1kg of dry soybeans per meter of water depth) for topdressing;

[0033] (2) Requirements for the pond: The facility pond for Wuzi cultivation is set up in a light-transmitting plastic greenhouse, and a sunshade net is erected...

Embodiment 2

[0048] Embodiment 2: cultivate loach seed according to the following steps

[0049] Step 1: First-level cultivation

[0050] (1) Cultivation of bait organisms: loach open bait cultivation pond 50 m 2 10 days before the loach water flower is stocked, use 0.5ppm chlorine dioxide liquid medicine to clear the pond of the loach opening bait cultivation pond, inject water and fertilize after 2 days; apply fermented chicken manure 450kg per mu, stir the bottom of the pond once every 2d; Sprinkle decomposed and fermented chicken manure twice, each time 75kg per mu; sprinkle EM bacteria once a week; if during the cultivation of bait organisms, it is found that the density of rotifers per milliliter of pond water is less than 40, then splash soybean milk (per mu, 1kg of dry soybeans per meter of water depth) for topdressing;

Embodiment 3

[0066] Embodiment 3: cultivate loach seed according to the following steps

[0067] Step 1: First-level cultivation

[0068] (1) Cultivation of bait organisms: Loach open bait cultivation pool 60㎡, clear pond with 0.5ppm chlorine dioxide solution for loach open bait cultivation pond 10 days before loach water flower stocking, inject water and fertilize after 2 days; apply fermented per mu Chicken manure 500kg, stir the bottom of the pond once every 1d; after that, sprinkle decomposed and fermented chicken manure twice a week, 100kg per mu each time; sprinkle EM bacteria once a week; If the density of rotifers is less than 40, then sprinkle soybean milk (1kg dry soybeans per mu, water depth per meter) for topdressing;

[0069](2) Requirements for the pond: The facility pond for Wuzi cultivation is set up in a light-transmitting plastic greenhouse, and a sunshade net is erected on the greenhouse; water peanuts are transplanted in the pond, and the area accounts for 50% of the c...

Abstract

The invention discloses a loach fry culture method. A loach larval stage feed culture pond, a larva culture facility pond and a fry culture pond cooperate to finish two-stage culture of loach fries. Primary culture includes that loach seedlings are cultured into loach larvae, culture time is one week, loach fries grow to 1-1.2 centimeters, and the facility pond serves as a culture facility. Secondary culture includes that the larvae are massively cultured into the fries, culture time is four weeks, loaches grow to 4 centimeters or more, and the pond serves as a culture facility. The loach fry culture method solves the problem that current large-scale loach fries cannot be massively produced under the artificial control condition, large-scale loach fries are massively produced, and rapid development of loach industries is facilitated.

Description

technical field [0001] The invention relates to a method for cultivating loach seedlings, belonging to the category of loach seedlings, in particular to a large-scale cultivation method for loach seedlings. Background technique [0002] Loach belongs to Cyprinidae, Cyprinidae, Loachidae, and Loach. There are many species in this genus, including Misgurnus anguillicaudatus, Misgurnus dabryanus, Inner Mongolia loach (Misgurnus bipartitus), cyan loach (Misgurnus lividus), pseudo loach (Paramisgurnusdabryanus guichcnot), two-color medium loach (Mesomisgurnus bipartitus), etc. There are more than 10 kinds in the world, and the appearance is almost the same. Usually, loach is mainly used for breeding. In recent years, in our country, we have developed the cultivation of paramisgurnus dabryanus and Taiwan loach. Loach is rich in nutrition and delicious in taste. Its protein content reaches 21%, and its medicinal effect is remarkable. As a nourishing food, it is more and more pop...
