Embodiment 1

[0032] A method for cyclic breeding of prawns includes the following steps:

[0033] Continuously pump the culture water in the prawn culture pond to the sedimentation tank for precipitation, then perform ozone sterilization and disinfection, the activated carbon adsorbs residual gas and harmful heavy metals, biological filtration treatment, and the traditional Chinese medicine liquid is added to the culture water after the biological filtration treatment, Then oxygenate to make the dissolved oxygen content in the water ≥7mg / L, warm to 25-28℃ and then return to the prawn breeding pond;

[0034] Wherein, the sedimentation tank performs precipitation to remove granular waste in the aquaculture water;

[0035] The biological filtration treatment adopts a composite microbial viable preparation mixed with Bacillus licheniformis, xanthan gum degrading bacteria, Bacillus pumilus, Rhodopseudomonas palustris, and Lactobacillus plantarum for degradation treatment; the circulation of the cultur...

Abstract

The invention provides a prawn cycling culture method. The method comprises the following steps that culture water in a prawn culture pond is continuously pumped into a sedimentation tank for sedimentation, and then ozone sterilization and disinfection, adsorption of residual gas and harmful heavy metal through activated carbon, and biological filter treatment are carried out in sequence; traditional Chinese medicine liquid is added into the biological filtered culture water, oxygenated, heated and returned back to the prawn culture pond. The culture water is effectively purified, the organic waste content in water is low, dissolved oxygen content in water is high, prawn diseases are effectively prevented, and the prawn survival rate is ensured; on the other hand, all-grass of clerodendrum bungei, dandelion, walnut leaves, quisqualis indica and serrate rabdosia herb are used for preparing the traditional Chinese liquid, the ingredients achieve synergistic interaction and mutual promotion, the excellent technical effects of promoting growth and improving immunity are achieved, and the prawn survival rate is improved.

Description

Technical field [0001] The present invention relates to the technical field of aquaculture, in particular to a method for circulating prawns. Background technique [0002] Prawns are also known as Penaeus chinensis and giant tiger prawns. They belong to Arthropoda, Crustacea, Decapoda, Penaeidae, and Penaeus. The growth of female prawns is generally 16-22 cm long and weighs about 50-80 grams, and the largest one can reach 30 cm and weighs 250 grams; male prawns are smaller, with a body length of 13-18 cm and 30-50 grams. The prawn is a wide-temperature and wide-salt marine animal with a long cylindrical body with flat left and right sides. The body is divided into head, chest and abdomen, and consists of 20 individual segments. The abdomen is long, muscular, and segmented. Shrimp meat has the characteristics of delicious taste, rich nutrition, high tonic effect and medicinal value. [0003] With the development of economy and the general improvement of people's living standards,...
