Is it OK to raise fish in a small ditch? What is the best fish to raise?

Yes, you can raise herring.

Grass carp, carp, etc., as long as it is difficult to die, it is fine.

Blackfish, herring, grass carp, crucian carp, carp, silver carp, bighead carp (silver carp),. Generally, freshwater fish mostly eat grass, and a few eat meat.

It is suitable for flowing water fish farming, and the breeding efficiency is also very good, but the most important thing is to prevent the damage of floods when the rainy season comes, and only when this problem is solved can it be raised. The aquaculture species are mainly predatory fish, such as grass carp, carp, crucian carp, etc.

If the water quality is good, the dissolved oxygen is abundant, and the water temperature can be controlled below 20 degrees, you can consider breeding cold-water fish, such as red mackerel, but the breeding technology requirements are high, and the investment is relatively large, of course, the benefits are more than 4 views. Conventional fish can be marketed for one year, and it takes more than two years for red mackerel to be marketed.

1. What are the common fish species raised in the river?

Different species grow in different rivers, lakes and water environments. However, many river fish species have similar characteristics and behaviors, such as crucian carp, carp, grass carp, silver carp, etc. are the more common river fish. They prefer to live in clear, gentle-flowing places and are adapted to a wide range of water temperatures.

In addition, some special fish species can be grown in different river waters. For example, mandarin fish, bighead carp, dace, herring, etc., in freshwater rivers can all be found in Chinese rivers. In large rivers such as the Yangtze River, there are also fish species such as tofu fish, four big carp, silver carp, and dace, which have become local specialties.

2. The high-quality fish nutrients in the river water are cautious

The fish in the river water are rich in high-quality protein and high-quality fats, and also contain various essential nutrients such as B vitamins, calcium, iron, phosphorus, etc. These ingredients are important for the healthy development and metabolism of the human body.

Among them, fat is the basis of fish oil. The green fish, crucian carp, carp, grass carp and other fish in the river are rich in fat, and their fatty acid components are conducive to enhancing human resistance, preventing cardiovascular diseases, reducing blood lipids and so on.

3. The food taboo of river fish

Although river fish are highly nutritious, there are some fish that are contraindicated for consumption. For example, when grass carp reproduces in large quantities in spring, it will accumulate a large amount of protein in the stomach, making the belly bloated, the meat is hard, and it is easy to cause diarrhea in the eater. Many river fish with poor water environment are also prone to parasitizing some insect eggs, and improper consumption can also cause intestinal problems.

Therefore, when we eat river fish, we need to pay attention to the species, growth environment, health status of the fish, etc., especially when choosing to eat healthy river fish stored or farmed, and it is also recommended to keep good food hygiene, and pay more attention to the cookedness and umami of river fish when cooking.

4. The significance of the protection of fish in river water

The ecological environment of the river waters has been damaged, and the fish stocks that inhabit them are also threatened. Therefore, the protection of fish in the river is not only an important part of maintaining the ecological balance of the river and potato stream, but also the responsibility of protecting human health and biodiversity.

We should do our best to reduce environmental pollution, reduce overfishing and poaching, and protect aquatic vegetation and aquatic insects along the banks of wetlands and barren beaches. By raising awareness of environmental protection, we will work together to protect the rivers and lakes that nurture fish in our waters, so that they can continue to provide us with abundant resources and food.

The river water can be used to raise fish. However, the river water is generally only suitable for raising fish in the river, and if it is an ornamental fish, it is best to use tap water. Although there are fish in the river, it does not mean that the river water is absolutely clean and hygienic, it may contain a small amount of pollutants, but the fish in the river have adapted to it.

However, ornamental fish are fragile and cannot adapt to river conditions, so they need to be raised in cleaner tap water. <

1. Trapped water: To raise water, you need to trap water first. Although the tap water is relatively clean, it is still because disinfection will leave a small amount of chlorine, which is very bad for the health of the fish, so it is necessary to remove chlorine by trapping the water, and put the water in the sun for one to three days after being connected, or you can use aeration to remove chlorine.

2. Filtration: After the trapped water is completed, the water can be injected into the fish tank, but the fish cannot be released immediately, but the filter should be opened, and the water should be circulated and filtered several times to filter out the impurities in the water and make it clearer. This is also helpful for subsequent fish farming, and can also improve dissolved oxygen.

3. Culture: Because it is new water, it is necessary to cultivate a little nitrifying bacteria to raise fish. Nitrifying bacteria are beneficial bacteria that convert ammonia nitrogen into nitrate, which can prevent rapid deterioration of water quality and is very helpful for the health of fish.

In addition to pouring the cultivation liquid every week, the light should be turned off and the oxygen should be turned off.
