Embodiment 1

[0045] A method for cultivating yeast rotifers, comprising the steps of:

[0046] 1. Set up the culture pool

[0047] The cultivation pool should be built near the nursery field, breeding farm, convenient transportation, convenient water source, sheltered from the wind and facing the sun. It is best to choose a place with a higher terrain to facilitate construction and drainage. Select the cement pond as the cultivation pond, the depth of the pond is 100 cm, and the area is 2000 square meters. The bottom of the cement pond is covered with 8 cm thick silt, and the silt comes from the fish pond. The number of cement pools is generally 3, which is convenient for dividing pools at the same time, feeding water in batches for cultivation, and harvesting alternately.

[0048] The cultivation tank is equipped with a water circulation heating system, a filtration system, a water inlet pipe, a water outlet pipe, and a water pump. The cement pool is provided with a water inlet and a wa...

Embodiment 2

[0078] A method for cultivating yeast rotifers, comprising the steps of:

[0079] 1. Set up the culture pool

[0080] The cultivation pool should be built near the nursery field, breeding farm, convenient transportation, convenient water source, sheltered from the wind and facing the sun. It is best to choose a place with a higher terrain to facilitate construction and drainage. Choose the cement pond as the cultivation pond, the depth of the pond is 80 centimeters, the area is 3000 square meters, the bottom of the cement pond is covered with 5 centimeters thick silt, and the silt comes from the Yangtze River. The number of cement pools is generally 4, which is convenient for dividing pools at the same time, feeding water in batches for cultivation, and harvesting alternately.

[0081] The cultivation tank is equipped with a water circulation heating system, a filtration system, a water inlet pipe, a water outlet pipe, and a water pump. The cement pool is provided with a wat...

Embodiment 3

[0111] A method for cultivating yeast rotifers, comprising the steps of:

[0112] 1. Set up the culture pool

[0113] The cultivation pool should be built near the nursery field, breeding farm, convenient transportation, convenient water source, sheltered from the wind and facing the sun. It is best to choose a place with a higher terrain to facilitate construction and drainage. Select the cement pond as the cultivation pond, the depth of the pond is 120 centimeters, and the area is 2000 square meters. The bottom of the cement pond is covered with 10 centimeters of thick silt, and the silt comes from the seaside. The number of cement pools is generally 5, which is convenient for dividing pools at the same time, feeding water in batches for cultivation, and harvesting alternately.

[0114] The cultivation tank is equipped with a water circulation heating system, a filtration system, a water inlet pipe, a water outlet pipe, and a water pump. The cement pool is provided with a ...

Abstract

The invention belongs to the technical field of aquaculture, and particularly discloses a rotifer culture method which comprises the steps of culture pond arrangement, pond cleaning, water feeding, disinfection, water fertilizing, rotifer inoculation, rotifer culture, fertilizer supplementing, water adding and changing, bait casting, daily detection, disease control, rotifer harvesting and the like. According to the rotifer culture method, a cement pond is used as a culture pond, and a water circulation heating system and a filtering system are arranged, so that the water temperature can be conveniently regulated and controlled, rotifers can grow at the high temperature (25-30 DEG C), and the yield of the rotifers is increased; yeast, wheat bran, orange peels, corncobs, bunge pricklyash leaves, artemisia argyi, honeysuckle flowers and chlorella are fermented to prepare baits, so that the problem of single nutritional ingredients of the yeast and the wheat bran is solved, the rotifers are comprehensive in nutrition, the nutritional ingredients of the raw materials are converted into micromolecular protein peptides and other nutritional substances after the raw materials are fermented by the yeast, the rotifers can absorb the nutritional substances more easily, and the utilization rate of the bait is increased; and the cultured rotifers are strong in physique, high in survival rate and stable in yield.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating rotifers. Background technique [0002] Rotifers are one of the small zooplankton that are widely used as live bait during the artificial breeding stage of fish, shrimp and crab. In recent years, with the development of the shrimp and crab nursery industry and aquaculture industry, the consumption of rotifers as high-quality live bait is increasing. Therefore, the cultivation of rotifers can bring huge profits, and many farmers or nursery farms also turn their attention to the cultivation of rotifers. [0003] At present, the cultivation of rotifers mainly includes methods such as outdoor cement pond cultivation, indoor cement pond cultivation and factory plant continuous cultivation. Cement pond cultivation generally uses animal manure, chemical fertilizers, miscellaneous fish carcasses, etc. as fertilizer and water materials to cultivate rotifers, but the d...
