How are there fewer and fewer loaches that once covered the ditch ponds? Where's the loach?
Loach is a tentacle fish of the loach family, slender and smooth skin, because its environment is usually dull, with the basic absence of scales on the surface of the loach's body, it appears thicker and very soft. They are carnivorous, have a wide diet, and have tenacious vitality.
A few decades ago, loach was one of the common aquatic animals in people's lives, and they were once found in ditch ponds and became people's daily food and viewing objects. But nowadays, fewer and fewer loaches make people start to think about the question: Where are the loaches?
First, there are fewer and fewer wild loaches, what's going on?
1. Changes in the ecological environment
With the continuous development of cities and agriculture, many ecological changes, such as the construction of reservoirs and the reclamation of rivers, have greatly affected the living environment of loach. Changes in the aquatic environment are fatal to aquatic animals. The habitat of loach is originally a rich and diverse water environment, but due to the continuous degradation of the ecological environment, they can only survive in one or several water quality environments.
2. Deterioration of the water environment
The deteriorating water environment in many areas, such as sewage, wastewater and industrial water discharge, has led to an increase in pollutants in water bodies, and the survival chances of loach in this environment have decreased dramatically. Since the skin of loach is the main site of oxygen absorption, healthy skin is essential for the survival of loach. The deterioration of the water environment also makes it more difficult for loach to reproduce.
3. Overfishing and illegal fishing
In the past, loach used to be one of the main food materials due to material poverty, but due to the increasing demand for loach, overfishing and illegal fishing, the number of loach has declined rapidly. Although the loach has tenacious vitality, its reproduction and growth rate are very slow, and unscrupulous fishing is undoubtedly a "disaster" for the loach population.
Second, the value of loach.
Although wild loach is already very rare in the wild, farmed loach is a frequent market visitor, and even in short supply. Nowadays, the society has abundant material and can buy all kinds of aquatic products in the market, why is the demand for loach still so large?
1. Medicinal value
Loach is a high-value Chinese medicinal herb that is believed to have nourishing properties. Loach meat is warm, sweet, non-toxic, and has the effects of replenishing deficiency, warming and invigorating qi, tonifying kidney and aphrodisiac.
2. Food value
Loach is a delicacy with tender meat and delicious taste, and is popular for steaming, stir-frying and stews. Loach is cooked in a variety of ways and has a unique flavor, and is loved by people.
3. Economic value
Loach farming is also a huge industry. In China, loach farming dates back to the 60s of the last century and has become one of the main sources of income for many families and farmers.
4. Ornamental value
There are many kinds of loach, and because of their thick body size and smooth skin, they are increasingly used as ornamental, breeding and family pets. Loach also has ornamental value, making it a good choice for family aquarium fish.
Summary:
In modern society, the concept of protecting wild animals is becoming more and more popular, and the protection of creatures such as loaches has become a topic of common concern in the whole society. At the same time, it also needs the support of policies and regulations and the joint protection of the whole people to allow the loach to survive and develop healthily in the aquatic ecosystem, because it is also an indispensable part of the ecological environment.
