Embodiment 1

[0017] Embodiment 1. Optimization of acetic acid concentration and electrode plate electrification time in acetic acid treatment tank

[0018] Set six groups of acetic acid concentration: 20ml / m 3 , 40ml / m 3 , 60ml / m 3 , 80ml / m 3 , 100ml / m 3 , 120ml / m 3 , respectively, immersed the grouper stimuli for 20 min, and counted the stimuli in the gills of the grouper before and after soaking, and observed the stress response of the grouper. The test results show that the concentration is 20ml / m 3 , 40ml / m 3 , 60ml / m 3 , 80ml / m 3 , 100ml / m 3 , 120ml / m 3 After soaking in the acetic acid solution, the irritated Cryptonucleus on the gills of the grouper was reduced by 10%, 20%, 34%, 37%, 37%, and 38%, respectively. Diagonal grouper pair 20ml / m 3 , 40ml / m 3 , 60ml / m 3 , 80ml / m 3 The concentration of no stress response, to 100ml / m 3 , 120ml / m 3 A stress response occurred at the concentration. Therefore, the concentration of acetic acid in the acetic acid treatment tank is...

Embodiment 2

[0020] Embodiment 2. Optimization of ultraviolet light treatment time

[0021] Ultraviolet light with a wavelength of 280-300 nm was used to treat C. serrata infected with C. spp. for 0 min, 4 min, 6 min, 8 min, 10 min, and 12 min, respectively. Counting was performed and the stress response of the oblique grouper was observed. The test results showed that the treatment of 0min, 4min, 6min, 8min, 10min, and 12min reduced the C. irritans by 0%, 5%, 10%, 28%, 29% and 30%, respectively. There was no stress reaction in the grouper with 0, 4, 6, and 8 minutes of treatment, but the grouper appeared with a stress response after being electrified for 10 min and 12 min. Therefore, ultraviolet light treatment was selected for 8 min.

Embodiment 3

[0022] Embodiment 3. Optimization of the intensity of the electromagnetic field in the magnetization treatment area

[0023] Four experimental groups were set up. The first group had an electromagnetic field strength of 230-250mT, the second group had an electromagnetic field strength of 730-750mT, the third group had an electromagnetic field strength of 430-450mT, and the fourth group had a change from weak to strong and then weaker. Electromagnetic field, blank control group was not exposed to electromagnetic field. The groupers infected with stimuli were treated for 1 hour respectively, and the fourth group was exposed to electromagnetic fields of 230-250mT, 730-750mT, and 430-450mT for 20 minutes, respectively. Before and after treatment, the gills of grouper were stimulated. Cryptocaryon worms were counted. The experimental results showed that the fourth group of electromagnetic field treatment had the greatest effect on the stimulation of Cryptonaria, which reduced the ...

Abstract

The epinephelus coioides culture treatment system capable of preventing and treating cryptocaryon irritans is created for the first time, multiple effective physical and chemical treatment means are screened and optimized, and an effective resisting effect is achieved for cryptocaryon irritans infected epinephelus coioides. The epinephelus coioides culture treatment system comprises an acetic acid treatment pond, a hunger treatment area, an ultraviolet light treatment area, a magnetization treatment area, an oxygenation treatment area, an ultrasonic treatment area, an orange green light treatment area and a nutrition enrichment pond which are arranged in sequence, and the culture treatment system obtains good effects no matter in an experimental research stage or a production practice stage.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a culture treatment system which can effectively improve the survival rate of grouper. Background technique [0002] The oblique grouper belongs to the order Perciformes, Asteridae, and Grouper. Because of its tender meat, delicious taste and rich nutrition, it is favored by the Southeast Asian market. The oblique grouper has the characteristics of fast growth, strong adaptability to the environment, high survival rate, and significant economic benefits, so it is very popular among aquaculture operators. Today, the cultivation of oblique grouper has become one of the important industries of marine aquaculture in my country. Since 2015, the aquaculture output has exceeded 100,000 tons, and it is the main object of marine aquaculture in the southern coastal provinces of my country. There are mainly cage culture, pond culture and so on. However, with the rapid increase in the...
