Problems solved by technology

[0004] However, the traditional method of ecological seedling raising in outdoor ponds is difficult to control due to its water quality environment, light conditions, beneficial food organisms and harmful organisms, and is greatly affected by the environment and climate, resulting in low seedling survival rate and seedling uniformity. Low, poor product quality, unable to meet market demand, and due to artificial overfeeding and excessive use of chemicals in the breeding process, water pollution, a large amount of sewage discharge will cause further pollution to the environment

Embodiment 1

[0068] A kind of factory breeding method of horse friend fish, it comprises the following steps:

[0069] Step 1. Isolate the nursery workshop and nursery pool and their disinfection treatment:

[0070] 1) Each isolated seedling workshop is 828m 2 , divided into left and right groups, a total of 20 indoor isolated seedling ponds, each 20 m 2 , pool height 1.5m;

[0071] 2) Dissolve 1kg of strong chlorine in water to make a concentration of 200ppm, and thoroughly disinfect the nursery workshop and nursery pool.

[0072] Step 2, comprehensive treatment of seedling water:

[0073] 1) The seawater is filtered through coarse sand, fine sand, activated carbon, and screens in sequence, and then pumped to the high-level reservoir. The area of ​​the high-level reservoir is 100m 2 , 3m high;

[0074] 2) Dark precipitation for more than 24 hours in the high-level reservoir;

[0075] 3) Chemical and physical treatment: Thorough disinfection with 5ppm of strong chlorine, neutralizati...

Embodiment 2

[0124] Select No. 3 seedling ponds for experiment:

[0125] 1. On June 20, 2012, 1kg of strong chlorine was dissolved in water to make a disinfectant solution with a concentration of 200ppm to thoroughly disinfect the nursery pond, and cleaned it for later use.

[0126] 2. On June 16, 2012, seawater from water sources in the sea area was pretreated as follows:

[0127] 1) The seawater is pumped to the high-level reservoir after being filtered by the coarse sand, fine sand, activated carbon and screen of the sea water source filter device. The area of ​​the high-level reservoir is 100m 2 , 3m high.

[0128] 2) 25 hours of dark precipitation in the elevated reservoir.

[0129] 3) Chemical and physical treatment: Thorough disinfection with 5ppm of strong chlorine, neutralization and detoxification with 2.5ppm of sodium thiosulfate after 24 hours and aeration for more than 48 hours, and high-speed water pump for 3 hours at the same time.

[0130] 4) Three-level sand filtration ...

Embodiment 3

[0163] Select No. 5 nursery ponds to carry out experiments:

[0164] 1. On March 12, 2013, 1kg of strong chlorine was dissolved in water to make a disinfectant with a concentration of 200ppm to thoroughly disinfect the nursery pool, and cleaned it for later use.

[0165] 2. On March 8, 2013, the seawater from the water source in the sea area was pretreated, and the steps were the same as in Example 2.

[0166] 3. On March 13, 2013, pretreated seawater was added to the nursery pool to 1.3 meters, the seawater salinity was adjusted to 32.3‰, the pH value was 7.8, and the dissolved oxygen was 4.8mg / ml, and ethylenediaminetetraacetic acid was put into the nursery pool Disodium 2.8ppm, Shuangshuiling 1.6ppm, to adjust water quality.

[0167] 4. On March 1, 2013, No. 2 bait pond was selected to cultivate open bait. The bait pond has an area of ​​2 mu and a water depth of 1.3m. After dissolving 50ppm bleaching powder in water, the whole pond was sprayed and disinfected. Added on Mar...

Abstract

The invention relates to the technical field of breeding for seafood seeds, in particular to a method for industrially breeding king salmon fry. The method includes steps of comprehensively treating fry breeding water; releasing fertilized eggs; manufacturing fry breeding initial feed; biologically regulating and managing the quality of the fry breeding water; performing classification and pond distributing management on the fry, and the like. The temperature, the illumination, the transparency, dissolved oxygen, the salinity, a pH (potential of hydrogen) value, harmful substances, disease organisms and the like of each indoor isolated fry breeding pond are effectively controlled, so that fry breeding environmental conditions are optimized, the stress resistance and the disease resistance of the fry are improved, the quality of the fry is enhanced, and a survival rate of the fry is increased. The method has the advantages that a key technology for breeding the king salmon fry is implemented, an efficient and environment-friendly fry breeding mode is provided, a novel high-end aquaculture variety is additionally provided for the marine aquaculture industry, and a gap in technologies for breeding the king salmon fry in China is filled.

Description

technical field [0001] The invention relates to the technical field of marine seedling breeding, in particular to a method for industrialized seedling raising of horse friend fish. Background technique [0002] Traditional mariculture species include bream, perch, grouper, yellow pomfret, etc., and then develop into cobia, large yellow croaker, American red fish, dragon grouper, hybrid dragon tiger grouper, etc. The seedlings used for these seafood are Most of the methods are to carry out ecological seedling raising in outdoor open-air ponds. This seedling raising method is greatly affected by the region, climate and season, and it is very unstable. The shortened breeding time that year seriously restricted the development of the marine aquaculture industry. The market demand of the current traditional cultured species is relatively saturated, and the breeding efficiency is low, and there is a lack of new alternative species. [0003] Mayou fish is a fatty and precious fis...
