Pollution-free healthy culture method of grouper in pond

Abstract

The invention discloses a pollution-free healthy culture method of grouper in a pond, which comprises the following steps: (1) pond preparation: selecting sand substrates or silt substrates as pond substrates, firstly insolating and dredging, then pouring the substrates into deep sea water, applying quick lime per mu for sterilizing and improving the substrates, and discharging the quick lime after 24h; (2) working before seeding: after the pond is prepared well, pouring water, sterilizing the whole pond with chlorine dioxide, and applying special fertilizer for aquiculture and beneficial microbial agents containing bacillus after 24h; (3) seedling stocking: stocking seedlings according to the density of 700-1300 per mu; (4) bait feeding: feeding fresh sea water trash fish cream at the early stage of culture of seedlings, and feeding soft granulated feed or special commercial feed for grouper at the middle and later stages of culture of seedlings; and (5) water quality management: controlling the transparency and the pH value of pond water, and regularly applying beneficial microbes once into the pond. The culture method of grouper of the invention controls the water quality by applying beneficial microbes and organic fertilizer, reduces the use of medicines and improves the value of products.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a pollution-free and healthy grouper pond cultivation method. Background technique [0002] Grouper belongs to the order Perciformes and the genus Grouper. Because of its rich nutrition and delicious meat, it has been welcomed by domestic and foreign consumers in recent years. At present, artificial breeding of grouper is being actively carried out in various coastal areas. However, the traditional farming methods are high in cost, heavy in pollution, low in output, and poor in quality. For example, shallow sea cage culture requires a large number of cages and a large number of personnel to guard them. It is vulnerable to natural disasters. Grouper often escapes. There are many poor diseases, pesticide application, excretion, and residual bait further aggravate the deterioration of the cage culture environment, resulting in low grouper culture efficiency, poor quality, and hidden health ...

However, the traditional farming methods are high in cost, heavy in pollution, low in output, and poor in quality. For example, shallow sea cage culture requires a large number of cages and a large number of personnel to guard them. It is vulnerable to natural disasters. Grouper often escapes. There are many poor diseases, pesticide application, excretion, and residual bait further aggravate the deterioration of the cage culture environment, resulting in low grouper culture efficiency, poor quality, and hidden health and safety hazards in eating; although some closed and intensive farming models have quietly emerged and got rid of Due to the constraints of the natural environment, problems such as non-standard farming techniques and the abuse of antibiotics are still prominent, and problems such as environmental pollution and low product quality in the grouper farming industry have not been effectively resolved
