Abstract

The invention discloses a litopenaeus vannamei larvae rearing and breeding method. The method comprises the steps of larvae rearing and breeding device assembly and sterilization, larvae rearing and breeding water sterilization, larvae putting and feeding, and larvae rearing water quality control. A breeding device adopted in the method is simple in structure, reasonable in arrangement and convenient and easy to operate and use. Automatic control can be achieved in multiple steps, live algae, probiotics and periodic blow down and water change are adopted for water quality control, ecological safety is guaranteed, the design is reasonable, the water environment for larvae rearing is easier to stabilize, and various diseases are prevented. The litopenaeus vannamei larvae rearing and breeding method is simple and efficient.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for cultivating and cultivating Litopenaeus vannamei fry. Background technique [0002] The prawn farming industry is the pillar industry of my country's aquaculture industry. Litopenaeus vannamei is the leading species of prawn cultured in my country. The annual farming area and output of Litopenaeus vannamei in my country have been stable at 250,000 hectares and 1.2 million tons for a long time. The annual demand for healthy and high-quality Litopenaeus seedlings exceeds 500 billion fish. Sustained and stable supply of healthy and high-quality seed is very important to ensure the sustainable development of my country's Litopenaeus vannamei aquaculture industry. [0003] At present, the traditional seedling cultivation methods rely on manual control for water addition, temperature control, feeding, water change, etc., and depend on workers' sense of responsibility, ha...
