Dear fishing friends, carp must be common, and even many people are masters of fishing carp, but if you know something about the situation abroad, you will find that the domestic carp is very small, but the foreign ones are completely different. Why is that? The editor also feels strange, after consulting countless materials, the editor is also distressed!
First, why is domestic carp small?
Compared with foreign carp, the size of domestic carp is generally smaller, which is mainly affected by the following factors:
1. Improper feeding management
In China, many carp farms are small in scale, uneven in technical level, and not strict in feeding management, which can easily lead to slow growth or small size of fish. In foreign countries, many carp farms are larger in scale, and the feeding management is more standardized and scientific, which can better promote the growth of fish and make them larger.
2. The variety is different
There are also certain differences between domestic and foreign carp species, and the growth rate and body size of different species are also different. Some domestic species of carp may be smaller due to factors such as biological basis.
3. Differences in water environment
Factors such as the quality of the water environment and temperature may also affect the growth and development of carp. In some parts of the country, water sources are seriously polluted, and problems such as high or low water temperature may also affect the growth of carp, resulting in its smaller size.
Therefore, in order to improve the size of domestic carp, it is necessary to strengthen the comprehensive effect of aquaculture management, improve technical level, improve water environment quality and other factors. At the same time, large-scale varieties suitable for domestic growth should also be introduced to promote the development of the domestic carp industry.
Second, why are foreign carp big?
Carp is one of the world's most important economic fish and is widely distributed in Eurasia and North America. Compared with domestic carp, many people find that foreign carp is generally larger. So, what factors are causing this phenomenon?
First of all, there are more high-quality carp breeding bases abroad, and the breeding conditions are more superior. Natural environment, water quality and climate are all important factors affecting the growth and development of carp, and some foreign areas are more suitable for carp growth. For example, the Nordic region has clear and pure water and a low temperature climate, which provides a very ideal environment for farming. Such breeding bases are usually equipped with a full set of advanced equipment, which can carry out fine management of aquaculture water quality, light intensity, water temperature, etc., to promote the growth and production of carp.
Secondly, in terms of variety selection and breeding, foreign carp varieties are also better. In fact, individual size is greatly affected by genetic and strain selection. Foreign carp have been improved for decades, and the selected strains have performed better, can better adapt to the local ecological environment, and have significantly improved body size and yield.
Third, foreign countries also have stricter breeding standards and quality control systems. Many countries have set precise quality standards for aquatic products, mandating strict regulation from source to consumer. In this way, the quality and safety of aquatic products produced by the farm can be ensured to the greatest extent, and the efficiency and product quality of breeding can be further improved.
3. Reflection and summary
Although the domestic carp aquaculture industry has achieved great results through continuous development, there is still a huge gap compared with foreign countries. In order to better develop the carp aquaculture industry, it is necessary to strengthen the comprehensive role of aquaculture management, improve technical level, improve the quality of the water environment and other factors. At the same time, large-scale varieties suitable for domestic growth should also be introduced to promote the development of the domestic carp industry.
Today's content is over, dear fishing friends, you must know, what do you think about this matter? How long do you think it will take us to catch up with the development of carp abroad? Finally, here, the editor still wishes all fishing friends and friends, a lot of fish and a full harvest!
