Embodiment 1

[0082] A method for industrialized ecological breeding of shrimp seedlings with high stress resistance and disease resistance, comprising the following steps:

[0083] Step 1. Establishment of isolated nursery workshops and standard nursery ponds and their disinfection treatment:

[0084] 1) 500m each of isolated seedling cultivation workshops 2 , divided into left and right groups, a total of 16 indoor seedling ponds, each 20 m 2 , pool height 1.5m;

[0085] 2) Each nursery pond is equipped with a skylight with a width of 2.0m and a length of 3.5m, and a side window with a width of 1.5m and a height of 3.5m; each nursery workshop is equipped with 24 skylights and 24 side windows to ensure sufficient light strength;

[0086] 3) Dissolve 2.0kg of strong chlorine essence (trichloroisocyanuric acid powder) and 0.5kg of potassium permanganate in water to make a mixed solution with a concentration of 250ppm, and thoroughly disinfect the nursery workshop and nursery pool;

[008...

Embodiment 2

[0159] Embodiment 2: select No. 2 nursery ponds to carry out experiment:

[0160] 1. On April 9, 2013, 2.0kg of strong chlorine essence and 0.5kg of potassium permanganate were dissolved in water to make a mixed solution of 200ppm strong chlorine essence and potassium permanganate to thoroughly disinfect the seedling cultivation workshop and nursery pool.

[0161] 2. On April 9, 2013, the seawater pumped up from the sea area underwent the following pretreatment:

[0162] 1) The seawater is filtered through coarse sand, fine sand, activated carbon, and screen in turn, and then pumped to the high-level reservoir. The high-level reservoir is cylindrical with a closed top and an area of ​​100m 2 , 3m high; the bottom of the reservoir is 10cm higher than the surface of the sand filter;

[0163] 2) Dark sedimentation: seawater undergoes dark sedimentation for more than 24 hours in the high level reservoir;

[0164] 3) Chemical and physical treatment: add seawater after dark prec...

Embodiment 3

[0217] Embodiment 3: No. 8 nursery pool is selected for experiment.

[0218] 1. On June 10, 2014, 2.0kg of strong chlorine essence and 0.5kg of potassium permanganate were dissolved in water to make a mixed solution of 200ppm strong chlorine essence and potassium permanganate to thoroughly disinfect the seedling cultivation workshop and nursery pool.

[0219] 2. On June 10, 2014, the seawater pumped up from the sea area was subjected to the following pretreatment, the steps of which were the same as in Example 2.

[0220] On June 15, 2014, the above-mentioned treated seawater was added to the nursery pond, the water depth was 1.3m, the adjusted specific gravity was 1.020, the pH value was 8.2, and the dissolved oxygen content was 5.1 / ml;

[0221] On June 16, 2014, 5.0 ppm of disodium edetate, 10.0 ppm of fluorspar powder, and 1.5 ppm of ionized calcium were added to complex heavy metals and remove other toxic substances.

[0222] 3. Healthy cultivation and reproduction of p...

Abstract

The invention relates to the technical field of marine product seed breeding and in particular relates to an industrialized iconological breeding method of young shrimps having high stress resistance and high disease resistance. The industrialized iconological breeding method comprises the steps of the construction and sterilization of an isolating breeding workshop and a standard breeding pool, the integrated treatment of breeding water, the healthy cultivation and reproduction of prawn parents, the throwing-in of healthy nauplius, the preparation of a breeding bait, the biological control and management of breeding water quality, bait feeding management, control of physical factors such as temperature and light, and the like. Due to biological control on the water environment of the indoor breeding pool and effective control on water temperature, illumination, transparency, dissolved oxygen, salinity, PH value, harmful substances, pests and the like, the breeding environmental conditions are optimized, the drug use, the feeding capacity and the drainage are reduced; in addition, the stress resistance and the disease resistance of the young prawns are enhanced, the quality and the survival rate of the young prawns are increased. The industrialized iconological breeding method of young prawns having high stress resistance and high disease resistance is used for solving the key technical problems of prawn breeding; a high-efficiency environment-friendly breeding mode is provided to promote efficient sustainable development of the prawn breeding industry.

Description

technical field [0001] The invention relates to the technical field of marine seedling breeding, in particular to an industrialized ecological seedling raising method for shrimp seedlings with high stress resistance and disease resistance. Background technique [0002] As a high-quality seafood, prawns are popular in domestic and foreign markets, and the demand for high-quality prawn products is increasing. Shrimp farming has become a dominant industry in my country's fishery industry and an important way for Chinese fishermen to get rich. However, in recent years, due to the continuous degradation of the quality of shrimp cultured species, the lack of good alternative species and the lagging of breeding technology for improved species, it is difficult to breed high-quality shrimp seedlings, and with the deteriorating water quality of the breeding environment, extreme weather often occurs , leading to frequent occurrence of various diseases, low success rate of shrimp farmin...
