There is a wild fish in the countryside, which is very fierce. Its food is small fish. Usually, as long as there is it in a pond, other fish will basically disappear, so many friends of aquaculture farmers regard it as one of the "natural enemies".
This kind of wild fish is known as "the king of water", "the king of fish" and "the king of fresh water" among the people. It is a carnivorous fish with a huge body, and you can often see big fish weighing more than 30 pounds.
The official scientific name of this kind of fish is _ fish. In some places, _ fish is also called copper head fish, water tiger, rod fish, yellow diamond, etc. Now the number of wild _ fish is scarce, and the market price can be sold to 45 yuan for a catty.
So _ can fish be farmed artificially? What about the market prospect?
_ How much is the fish market price per catty?
_ Fish can be sold in 45 yuan for a catty now, but the specific price details should of course be based on the actual region, because different regions have different levels of economic development, and the quality and quantity of fish, market supply and demand and other factors are different.
At present, according to the market price of fish in some areas, the average market price of fish is generally around one catty from 45 yuan to 50 yuan, and the price of wild fish is even higher, reaching about seventy or eighty yuan a catty when it is expensive.
You can tell me about the price of fish there. How much is it a catty?
_ What is the prospect of the fish market?
_ Fish's back is generally grayish brown, its abdomen is silvery white, and its dorsal fin and caudal fin are dark gray.

_ Fish culture technology
1. Water quality requirements: It is best to keep the pH value of water for aquaculture _ fish between 7 and 9, the ammonia nitrogen content in each liter of water is not higher than 0.03 mg, the salinity is not higher than 5%, the dissolved oxygen content in water is above 5mg/l, and the transparency of water is above 30cm.
It is best to breed in rivers and lakes.
2. Stocking density: it should be controlled at about 300 kilograms per mu, and 250 grams of silver carp can be mixed 100.
3. Feeding points: _ Fish fry can be fed with soybean milk, which is ground into soybean milk with three to four kilograms of dry soybeans per mu every day and spilled all over the pool.
When the body length of the fish reaches about five to ten centimeters, it is necessary to prepare live bait, which can be fed together with live bait and dead bait, and then gradually transition to feeding fish pieces.

_ Which is more powerful, fish or snakehead?

_ Fish is a famous natural enemy of freshwater fish, but many people have learned its ferocity.
_ Fish's temper is on the rampage, and it only moves forward without retreating. If you want to catch it, you need to find a stronger net, or you can catch it by bait fishing, hook rolling, etc.
I don't know if you produce this fierce large freshwater fish there. Some time ago, Xiaobian's family just got one from Huanggai Lake. It's neither too big nor too small, and it's about seven or eight pounds. It smells good after frying in oil.

_ Fish is also called "Yoko" in Xiaobian's hometown. Because of its rampaging temper, what is your _ fish called? Have you ever eaten fish?
