Embodiment 1

[0046] S1. Prepare the breeding system:

[0047] Disinfect the existing aquaculture system with a bleaching powder disinfectant with residual chlorine greater than 30ppm and soak it for 1 day, rinse it with fresh water 3 times, and inject natural seawater with a salinity of 25‰–35‰; the circulating water system needs to add 0.02g / L Yeast extract and 0.2ml / L nitrifying bacteria, run the circulating water system for at least 15 days, and cultivate the biofilm in the filter tank.

[0048] S2. Monitor the breeding environment and check whether it meets the preset environmental indicators:

[0049] The water temperature in the culture system is 18-20°C; the light time should be 12 hours (7:00-19:00), and the dark time should be 12 hours (19:00-7:00 the next day); the pH value is 7.5, and the dissolved The oxygen concentration is 6.8mg / L, the ammonia nitrogen concentration is 0.1mg / L, the nitrite nitrogen concentration is 0.1mg / L, and the sulfide concentration is 0.1mg / L.

Abstract

The invention discloses a flounder health condition evaluation method. The flounder health condition evaluation method comprises the following steps that after early-stage preparation of a culture system and monitoring of a culture environment, to-be-evaluated flounder is put into the culture system; health evaluation is carried out through capture and anti-capture behaviors, metabolism indexes, metabolism changes after acute stress, appetite recovery behaviors after stress autism, sand diving behaviors and circadian rhythm behaviors in sequence; and according to individual differences of physiological and behavior characteristics of the flounder, multi-term evaluation and grading evaluation are adopted, health evaluation standards are established, the health conditions of flounder groups in an artificial breeding environment and a natural environment are comprehensively evaluated, the breeding technology is improved, and meanwhile, healthy and sustainable development of flounder breeding management and the breeding industry is promoted.

Description

technical field [0001] The invention relates to a method for evaluating the health of aquaculture and marine organisms, in particular to a method for evaluating the health status of flounder and flounder. Background technique [0002] With the global extreme climate change and the intensification of the impact of human activities on the natural environment, the environment on which the living creatures in nature depend has undergone tremendous changes, posing a great threat to their survival. In addition, due to the relatively backward aquaculture management and breeding theory in my country, the water environment has deteriorated, seed resources have declined, and diseases have occurred frequently. In the normal breeding process of flounder and flounder, various environmental changes and human stress are unavoidable. The "weak or sub-healthy" individuals in the breeding group will appear anorexia and become ill first, and infect the whole group, thus causing large-scale dis...
