How much does the high temperature affect the aquatic organisms due to the decrease in the productio

The impact of high temperature on aquatic organisms is very large, and the production of hairy crabs in Yangcheng Lake has decreased due to the continuous high temperature, which is one of the effects of high temperature. High temperature exposure will affect the size of hairy crabs, and will also lead to the death of some hairy crabs. This situation will cause the price of hairy crabs to rise, and the impact of high temperature on aquatic organisms is fatal, so it is necessary to take measures to prevent high temperatures, and to make corresponding countermeasures for the growth of life in the water.

1.High temperatures affect the metabolism of microorganisms in the water, which in turn affects the quality of the water.

As the temperature gets higher and higher, the biochemical reactions of organisms in the water will also increase at a higher rate. Successive hot weather can cause severe depletion of dissolved oxygen in the river. If the temperature is too high, the microorganisms will also metabolize faster, and the oxygen they need will increase, so in hot weather, many microorganisms are in a state of hypoxia.

It causes a large number of microorganisms to die, which will cause great harm to the quality of river water. Cooling measures such as cold water spraying must be taken in a timely manner.

2.The temperature of the water also affects the amount of food that the organisms in the water eat, resulting in the slow growth of the organisms.

Fish above 35 degrees Celsius will eat significantly less, and the persistently hot weather in the south will have a great impact on the fish. The alienation effect in the aquatic body is greater than that of assimilation, and the growth rate of biogenesis will be relatively slowed down. And in the hot season, it is necessary to manage the water organisms in the lake, and the lake with too much organic matter in the water body should increase the use of probiotics.

3.Temperature also affects the reproduction and distribution of organisms in the water.

For example, hairy crabs in Yangcheng Lake are somewhat sensitive to temperature changes, which reduces the amount of reproduction. In addition, many fish lay eggs that do not have the right temperature to allow the eggs to grow healthily. Such high temperatures will only cause a large number of eggs to die, which will affect the reproduction of fish.

The growth of any organism requires the right temperature conditions, and too high a temperature will only affect their population. It will also make them instinctively seek out cooler waters.

Water temperature is one of the most basic and important factors in the water environment. Freshwater fish are cold-blooded animals, and their body temperature and a range of physiological activities are closely related to water temperature. Water temperature directly affects the body temperature of fish and their survival and growth.

High temperature will cause the death of many organisms in the water, and the water temperature will become high, and many organisms will not be suitable to live in this water, which will affect the reproduction of organisms.

After the high temperature, the crab came out of Yangcheng Lake, and when I saw this, I believe that for some foodies or people who like to eat crabs, they must have begun to waver. I even want to buy hairy crabs in Yangcheng Lake right away. However, for those who have never eaten Yangcheng Lake hairy crabs, they will definitely ask, what is the difference between it and ordinary hairy crabs?

Why is it so famous?

The main difference between Yangcheng Lake hairy crabs is that they have different nutrients, different growth environments, different tastes, and different fullness.

1. The nutrients are different. The nutritional content of Yangcheng Lake hairy crab will be higher than that of ordinary hairy crabs, because from the corresponding size and fullness, we can see that the protein and other minerals and vitamins contained in it are definitely much higher than those of other hairy crabs.

2. The growth environment is different. The reason why Yangcheng Lake hairy crab is delicious is also directly related to its growing environment. For ordinary hairy crabs, the growing conditions are not so harsh, and there is no fixed feeding cycle, so they can be sold on a large scale.

However, for hairy crabs in Yangcheng Lake, their requirements for water quality are extremely demanding, and they can not be carried out at any time.

3. The taste is different. The crab meat of Yangcheng Lake hairy crab is relatively delicious, and the taste is very tender, and the water content is high, so there is not too much fishy smell. However, ordinary hairy crabs have a strong earthy smell and the taste is not satisfactory.

4. The degree of fullness is different. Anyone who has ever eaten a common crab must know that many crab shells have empty or very little meat. However, among the hairy crabs in Yangcheng Lake, the meat in the crab legs is also very full.

Summary. The reason why Yangcheng Lake hairy crabs are loved by people is nothing more than the above reasons, the first reason is the different nutrients, the second reason is the different growth environment, the third point is the difference in taste, and the fourth point is the difference in fullness. However, the price of hairy crabs in Yangcheng Lake is definitely much higher than that of ordinary hairy crabs.

After seeing that it is profitable, unscrupulous merchants use counterfeit and shoddy products to sell hairy crabs, which not only seriously affects the reputation of hairy crabs in Yangcheng Lake, but also affects the normal market sales, so they must be severely punished according to law.

In the autumn season, hairy crabs are the best choice on the dining table of every family, for hairy crabs, Yangcheng Lake hairy crabs are the leader, and the long-term high temperature has led to the postponement of the listing of Yangcheng Lake hairy crabs, which has aroused the attention of many netizens on the Internet.

Hairy crabs in Yangcheng Lake have been postponed due to high temperatures.

This year, the large-scale breeding area of hairy crabs in Yangcheng Lake is concentrated in Kunshan, Jiangsu Province and Xuzhou City, Jiangsu Province, with an area of 450,000 mu. At the end of July, the temperature in some areas had reached more than 40 degrees, or even higher. According to the practice of previous years, this year's Yangcheng Lake hairy crabs will also be listed at this time.

But now it is different, there is low temperature weather in most areas, and it is difficult for hairy crabs to get out of the pond. For hairy crab farmers, sales have also been greatly affected, if you want to avoid this phenomenon in the process of breeding crabs, you must add a black shade net to lower, or reduce the strong sunlight, which can effectively provide a more comfortable production environment for hairy crabs.

Counterfeit hairy crabs are rampant.

A large number of "three-no" hairy crabs have appeared in Yangcheng Lake. The so-called three nos are no breeding area, no bait, and no environmental pollution. The standard of hairy crabs in Yangcheng Lake should reach more than 3 taels and more than 5 taels for each crab.

According to such a standard, the ** of each crab is between 60-80 yuan. Nowadays, there are many counterfeit products in the market, such as white crab shells, yellow belly, hard belly, no crab roe, fat body, fat ......These are the so-called Yangcheng Lake hairy crabs. And from the appearance point of view, the "three nos" cannot distinguish the authenticity at all; There are also individual businesses that use the "three nos" to attract consumers.

It's hard to buy crabs. Every year, due to environmental reasons, it is impossible for hairy crabs in Yangcheng Lake to continue to be listed on a large scale, so a large number of hairy crabs from other places pour into the Yangcheng Lake area, making a large number of crab farmers in the Yangcheng Lake area unable to breed hairy crabs according to the original plan to ensure the yield and quality, resulting in some consumers being unable to buy hairy crabs in time, and the hairy crabs in the Yangcheng Lake area cannot achieve brand effect.

Yangcheng Lake hairy crabs have been postponed due to high temperatures, some merchants estimate that sales will drop by 30%, and the maximum temperature will exceed 40 degrees Celsius.

On the occasion of the Mid-Autumn Festival, it is also the time of the year to taste crabs, however, this year's people who love to eat crabs will probably have a little regret, that is, because of the high temperature and drought in summer, which affects the growth of hairy crabs, the water surface temperature is usually suitable for them to hunt below 30 degrees, and this year's continuous high temperature has increased the water surface temperature and affected their surface feeding, so this wave of Yangcheng Lake hairy crabs in addition to less production, its size is also smaller, and according to climate factors, the fishing time of hairy crabs will be postponed to the end of September. A large number of listings will have to wait until after the National Day.

This year's Mid-Autumn Festival, Yangcheng Lake hairy crabs seem to be absent, so, among the crab products, is only hairy crabs worthy of the Mid-Autumn Festival? Is there no other crab that can replace it? Some people recommend Panjin river crab, in fact, Panjin river crab is a large category, it has a total of three varieties, namely rice field crab, river loop crab and wetland river crab, these three have their own characteristics.

The first kind of rice crab is a river crab that is polycultured in the rice field, because the feed is sufficient, so the size is relatively large, the meat is fat, and the excellent growth environment makes the rice field crab all yellow and full of fat.

The second kind of Hetao crab, this kind of crab belongs to the wild crab, because the feed is not as sufficient as the artificial breeding, the size of the crab here is generally smaller, but also because of the wild environment, so that they taste more delicious, when choosing to see whether the crab shell is bright and smooth, which is also a major feature of the Hetao crab, because of the formation of long-term erosion by the current.

The third kind of wetland crab, this kind of crab can combine the advantages of the first two at the time, the wetland environment has sufficient food, the crab meat is thick, and it belongs to the wild crab, the taste is full of umami, but the fishing work in this environment is also more difficult, so the most common Panjin crab on the market is mainly Hetao crab and rice field crab.

As for which one is delicious, Yangcheng Lake hairy crab and Panjin river crab, in fact, they all belong to Chinese mitten crabs, and the taste of a variety is not much different, the biggest difference is in appearance, hairy crabs have green backs and golden retrievers and golden claws, and they can get their hands on treats and gifts, while Panjin river crabs have black back and brown hair, or small short legs, which are not as good as hairy crabs in appearance.
