Problems solved by technology

Due to the difficulty in catching wild river crabs and the small quantity, they cannot meet the market demand, so artificial breeding is often used
At present, artificial breeding has poor water self-regulation ability, poor water quality, large water exchange rate, low resource utilization rate, slow growth and development of river crabs, and poor meat quality, which affects the economic benefits of river crab farming.

Abstract

The invention discloses a cultivation method capable of promote growth of river crabs. The cultivation method comprises a step S1 of pond construction: laying loam and sterilizing at the bottom of a pond, applying an organic fertilizer, planting aquatic plants, injecting clear water and regulating the pH value of the water body; a step S2 of juvenile crab putting: disinfecting and putting the juvenile crabs; a step S3 of feed management: feeding artificial feed 2-3 times every day; a step S4 of water quality management: throwing disinfectant in the pond every 9-15 days, timely removing pond impurities, and timely replacing the water; and a step S5 of capture. According to the cultivation method capable of promote growth of the river crabs, by optimization of a cultivation process, the water body self-adjustment capability is high, the water quality is good, the water replacement amount is small, the resource utilization rate is high, the river crabs grow and develop quickly, the meat quality is good, the cultivation cycle is short, and the method is conductive to improving economic benefit of river crab cultivation.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a cultivation method for promoting the growth of river crabs. Background technique [0002] River crabs often live in caves on the mud banks of rivers, rivers, and lakes. They are nocturnal and feed on fish, shrimp, animal carcasses, and grains. After the juvenile crabs, the meat of Zaijiang is fresh and tender, and it is a blind food that is deeply loved by people. River crab meat is fresh and tender, rich in nutrition, and has the functions of dispersing blood, renewing tendons and bones, and detoxifying knees, and is deeply loved by consumers. Due to the difficulty in catching wild river crabs and their small quantity, they cannot meet the market demand, so artificial breeding is often adopted. At present, artificial breeding has poor water self-regulation ability, poor water quality, large water exchange rate, low resource utilization rate, slow growth and development o...
