How can we reduce the impact of aquaculture on the surrounding environment? Any suggestions?

A) develop and improve the scientific aquaculture licensing system.

The development and improvement of the scientific aquaculture license system can improve the level of aquaculture management, control the scope and scale of aquaculture from the source, improve the quality of aquaculture personnel, improve market access standards, and also help to improve the quality of aquatic products. ** Plays an important role in the implementation process, and the management department is responsible for conducting a comprehensive audit of the specific area to determine the amount and scale of aquaculture that each area can sustain, as well as healthy and environmentally friendly farming methods. At the same time, the development of a strict aquaculture technical personnel assessment mechanism, also including the unit of breeding technology, equipment audit, etc., and finally a comprehensive assessment, only the assessment results to meet the standards can be issued licenses.

** The department should take regular and irregular ways to strengthen the inspection of aquaculture units and individuals in the jurisdiction, maintain the order of the aquaculture industry, and find that the environmental pollution is serious or exceeds the standard and must be rectified in a timely manner.

2) Optimize the aquaculture model.

The environmental pollution of aquaculture is very large because of the unreasonable breeding mode, coupled with the lack of scientific breeding concepts and advanced breeding technology of aquaculture personnel, resulting in low quality and poor efficiency of aquatic products. Environmental pollution is becoming more and more severe, which is not conducive to the healthy development of the aquaculture industry. Therefore, the most important issue in the development of aquaculture industry at this stage is how to optimize the breeding model, promote scientific breeding, change the ideology of aquaculture personnel, and implement and popularize scientific breeding technology.

To this end, the following ideas are proposed:

1.According to the production law, reproduction law, living habits and other characteristics of the breeding group, the appropriate breeding mode is determined. For example, tropical shrimp and green shrimp can be cultivated in rotation, first breeding tropical shrimp (giant river prawn), and then breeding green shrimp after fishing, which greatly improves the breeding efficiency, and saves the breeding land, which is very beneficial to farmers.

2.In the process of breeding, it is necessary to scientifically control the reproduction of water pathogens and improve the efficiency of aquaculture, and farmers need to learn more about aquaculture.

3.The use of life characteristics such as complementarity, interdependence, and co-survival between organisms, and the implementation of polyculture methods can not only reduce the content of harmful substances in the water body, but also improve the water environment, ensure that the water quality meets the standard, and is conducive to the coordination and balance of aquaculture and the environment.

The suggestion is that you can make a yard specially, and then it is best to seal the top, of course, you can directly go to the appropriate point, and you must do a good job of sealing measures, so that it is not easy to affect the surrounding environment, and the gas we discharge also needs to be treated to a certain extent, and the surrounding area will not smell this fishy smell.

Choose clean water quality, set up a barrier around the breeding area, isolate other water sources, you can reduce the impact on the surrounding environment, my suggestion is to use water tanks to breed aquatic products, so that it is more large-scale, and at the same time can protect the water environment.

First of all, we should choose the right breeding land, and then we should also learn professional breeding technology, but also need to ensure that the feed is sufficient, and we should also pay attention to the prevention of diseases when breeding, so as to reduce the impact on the surrounding environment.

You can plant some trees, pay attention to the treatment of sewage, be sure to pay attention to the surrounding environment, and when spraying some medicines, you must do a good job of protective measures to avoid other animals and plants from being affected.

It is necessary to choose high-quality aquatic products, replace water resources in time, treat stains and garbage in water in a timely manner, and discharge them reasonably.

With the improvement of living standards, people's demand for various means of living has also been stimulated. The corresponding livestock and poultry breeding industry has also changed from a small-scale breeding method to a large-scale intensive belt breeding model. Large-scale farming can significantly improve the efficiency of breeding, and can create more economic and chaotic benefits for farmers in the same time.

At the same time, the damage caused by large-scale livestock and poultry breeding to the ecological environment is becoming more and more serious.

With the continuous growth of aquaculture scale, more and more problems, coupled with the lack of scientific breeding concepts and breeding technology of farmers, have led to changes in the aquaculture environment, causing certain pollution to the surrounding waters, and water resources are deteriorating day by day.

1) Cause changes in the pH of the water body.

The feces discharged from aquatic products in the process of growth and development are alkaline, and dissolved into water makes the water environment alkaline, and the change of pH not only affects the water body, but also directly affects the organisms in the water. The alkaline substances in the water body continue to increase, which directly affects the acidic gastric juice of aquatic organisms and affects the growth and development. For example, excessive feces lead to a pH of 8 in the water body, which affects the tail function of aquatic organisms; Or pH 6, aquatic organisms such as fish and shrimp will store acidic substances in the body, once humans eat these fish and shrimp, the damage to the body is very great.

For another example, the dissolved oxygen content in the water body is excessive, and ions are generated under the influence of the environment, which becomes toxic substances after encountering water, which seriously threatens the growth of aquatic organisms, and will also destroy the water quality conditions of aquaculture waters, resulting in huge economic losses.

(2) Causing changes in the dissolved oxygen parameters of the water body.

Under normal circumstances, changes in external climate and temperature will directly affect the parameters of dissolved oxygen in the water body, destroy the ecological environment of the water body, and are not conducive to the survival of fish and shrimp and other organisms. The temperature is high in summer, the parameters of dissolved oxygen in the water body will be reduced, at this time fish and shrimp and other organisms need high oxygen content, if the oxygen content can not meet the needs of aquatic organisms, it is bound to cause biological hypoxia to affect health, and in serious cases, it will even cause fish to die of mass hypoxia, pollute the water environment, and will also have an adverse impact on the surrounding ecological environment.

(3) Causing an imbalance between beneficial and harmful flora in the water body.

In order to control aquatic diseases and ensure the normal growth and development needs, the aquaculture process needs to manually put appropriate chemicals and feed to balance the water environment, but must be in accordance with the national standards for delivery, standardized operation. If the operation is improper or for the sake of profit, the abuse of chemicals and feed can easily cause the ecological imbalance of the water body, resulting in a large number of aquatic life deaths and water pollution.

Yes. Because some things in the water will flow and penetrate into the surrounding soil, which will have a certain impact on the environment at this time.

Yes. This is because a lot of things are put in the water during farming, which will affect the surrounding water quality and affect the surrounding environment.

There is no impact because the farming process is very clean, does not cause any environmental impact, and does not affect the air.

1.The aquaculture water environment continues to deteriorate. With the expansion of the scale of aquaculture and the increase of density, the water environment of aquaculture continues to deteriorate due to the increasing consumption of water environment and soil environment, as well as the use of various drugs in the breeding process.

2.The main mode of production.

backward, industrial structure.

It is unreasonable, and the growth mode is backward.

3.The convergence of breeding models, the homogenization of products, the lack of innovation, and the lack of highly competitive breeding objects.

4.Heavy output, light quality, lack of brand, is not conducive to the sustainable development of the aquaculture industry.

5.The degree of intelligence, automation, mechanization and informatization is low. This is due to the characteristics of the aquaculture industry and the level of education of the aquatic workers.

Requires a lower decision.

6.The quality and safety of aquatic products is worrisome. Although the relevant departments of the state have increased the management and punishment, there are still many problems in the breeding process, such as non-standard drug use, excessive breeding density, and substandard breeding water and feed.

7.The management level of modern agricultural enterprises is backward, the technological innovation ability is weak, and there is a serious shortage of talents.

8.Disease problems are prominent.

1.Blindness.

In rural aquaculture, people have begun to carry out high-density aquaculture work due to blind follow-up, which has led to the deterioration of the water environment. Water is the main environmental factor in the survival and development of organisms, and maintaining the quality of water can promote the positive development of aquaculture. In recent years, the gradual development and construction, farmers are still pursuing a short period of economic development, affecting the market development demand, these high-yield, high-density farming methods are a blind phenomenon, during the breeding period, the lack of advanced knowledge and experience of guidance, resulting in a large number of manure and pollutant substances in rural aquaculture.

At the same time, some farmers put a lot of manure into the fertilization of water bodies, resulting in serious eutrophication of water bodies, affecting water quality and the normal growth of animals and plants.

2.Lack of knowledge.

Farmers do not have sufficient knowledge of feeding, resulting in underutilization of feed, resulting in serious water pollution. Under the current market development trend, there are many types of aquatic feed, but the quality varies greatly. Therefore, in the daily feeding work, some nitrogen-containing organic matter can not be guaranteed, resulting in insufficient nutrition of the farmed organisms, which brings a series of problems.

Affected by the feed itself, the nutrients are not balanced, resulting in the limited intake of elements by the breeding objects, resulting in serious pollution. For some feed or residues that are not utilized, if relevant measures are not taken to decompose the organic matter, it will increase the cost of feed, cause hypoxia at the bottom of the fish pond, and thus increase some parasites or bacteria. At the same time, in some bad weather conditions, it will also affect some organisms and restrict the acquisition of economic benefits.

3.Drug abuse.

At present, aquaculture in rural areas is mainly outdoor farming, which has been used for many years without disinfection treatment, which leads to the production and infection of some pathogens. At the same time, the quality of some seedlings is not good enough, resulting in some breeding objects are prone to produce pathogens, in the process of underwater aquaculture, some pathological conditions can not be grasped, and reasonable drugs can not be given. Due to changes in environmental factors, some pathogenic microorganisms multiply in large numbers, causing the occurrence of diseases.

Some farmers lack relevant experience, for the problems that arise during the breeding period, can not be effectively solved, especially the use of some drugs, in the long-term development situation, not only will lead to the organism to retain more excess substances, some products into the market, will endanger people's health.

4.Wastewater is not treated.

Untreated wastewater is discharged around the water body, which will cause serious pollution. In aquaculture, the influence of weather conditions can cause algae falling, disease outbreaks, and problems such as blackening of water bodies. Some users use improper breeding methods, which will cause great harm to the surrounding water quality.

During the use of polluted river water, the surrounding farmers have produced secondary pollution, which not only causes greater economic losses, but also affects the development of the aquaculture industry.

There are a lot of problems. Now people do not have their own knowledge at all, the breeding work blindly follows the trend, and the density is particularly large, resulting in the deterioration of the ecological environment, and there is no knowledge, the feed is not sufficient, and the difference in quality is also relatively large, so the income is not very good.

For example, the water quality is relatively poor, and the water resources are not replaced in time, so the production of aquatic products is reduced in a large area, and it is also possible that the water environment continues to deteriorate, or the farmers do not grasp the technical points, or the quality of fish fry is relatively poor.

I think there are safety problems, water quality problems, nutrition problems, feed problems, and environmental problems.

The main problems currently faced in aquaculture:

First, the contradiction between industrial development and resources and environment has intensified. The failure to get rid of industrial development is based on the large number of possession, dependence and even destruction of resources, environment and other productive factors, and ecological security has become an important factor restricting the development of aquaculture. External water scarcity and pollution restrict aquaculture, and aquaculture sewage affects the external environment.
