Problems solved by technology

In 2018, the output of the crayfish farming industry reached 48.5 billion, but the market price generally showed a pattern of high at both ends and low in the middle, that is, the price was high when it was first listed, and the price was relatively low when it was listed in May and June. The quantity is small, the price rises again
However, most of the indoor breeding techniques have many defects in water source, nutrition, and breeding environment. For this reason, the present invention proposes a perfect method for indoor farming crayfish

Abstract

The invention discloses a method for farming crayfishes with indoor circulating water and belongs to the field of aquaculture. The method mainly comprises the following steps: selecting a site to install crayfish farming equipment, monitoring water quality conditions and water quality according to the farming cycle and different growth stages, selecting microbes and nutritive materials, and adjusting the usage amount of the microbes and nutritive materials. The method is small in influences of natural conditions, simple and feasible, and achieves effects of reducing emission of farming sewageand realizing excellent economic benefits and ecological benefits.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating crayfish in indoor circulating water. Background technique [0002] Crayfish belong to crustaceans, scientific name: Procambarus clarkii, also known as Procambarus clarkii. Crayfish are widely distributed in various water bodies. They have strong adaptability to eutrophication and low oxygen in water bodies. They have poor predation ability, but they have strong vitality and reproductive ability. Crayfish meat is soft and easy to digest. The protein content of shrimp meat is higher than that of most freshwater fish and shrimp, accounting for 16%-20% of the total. It is also rich in magnesium, zinc, iodine, selenium, etc. Crayfish can also be used as medicine, which can reduce phlegm and relieve cough, and promote wound healing after surgery. In 2018, the output of the crayfish farming industry reached 48.5 billion, but the market price generally showed a patt...
