Why are loaches bigger cheaper and why loaches don t grow as big as fish

The reason why loaches are bigger and cheaper is because large loaches are basically farmed, and they are inferior to natural loaches in terms of taste and nutrition.

It is difficult for loaches to grow in rivers because they have little food and a lot of activity, so they are delicious and have a firm meat.

The farmed loaches are fed with fish feed, with a small range of activities, less activity, and poor water quality, so the meat quality and taste are worse. Moreover, the yield of farmed loaches is very large, and the supply exceeds demand, so it is naturally low.

First, the cement pool benefit analysis: a 10 square meters of cement pool construction cost 300-400 yuan, seedlings can be put 30 catties, the purchase of 1 kg of loach seedlings 9-10 yuan, loach seedlings 10 yuan calculation: 30 catties 10 yuan catty = 300 yuan; Feed self-formulated:

Each pound of loach consumes the cost of feeding, after 4 months of feeding we calculate by 4 times, the cost of feeding in yuan, the cost of feed 396 yuan, 15 yuan of drugs, a 10 square meters of cement pool total investment of 1100 yuan, can produce 120 pounds of loach, just 4 months of output value of 1440 yuan, annual net profit: (1440 yuan (output value) - 300 yuan (seedlings) - 396 yuan (feeding cost) - 15 yuan (drug) = 729 yuan net profit). Each mu can build 50 pools of 10 square meters, and the annual output of loaches per mu can reach 6,000 catties, 12 yuan per catty, and the output value is 10,000 yuan.

Subtract the cost, and make a profit of more than 10,000 yuan per mu.

Cage benefit analysis 50 cages per mu of ponds, the cost of cages is 3,000 yuan (3 years of use, 300 yuan per year), 1,000 kg of seedlings per mu, 10 yuan per catty, 10,000 yuan, 12,000 yuan of feed, 750 yuan of drugs and other expenses, and the total cost of input per mu is about 25,750 yuan. The loach per mu is 4,000 catties, 12 yuan per catty, and the total income is 48,000 yuan. Subtract the cost, the profit per mu is 22,250 yuan.

In addition, the income of silver carp and green shrimp outside the cage is higher.

Second, loaches are not difficult to breed, but the key is to learn the technology well. I heard that Xinmin ecological breeding in Huaihua City, Hunan Province is mainly engaged in the breeding of yellow eel, loach, four major fish, pig raising, chicken raising, earthworms, mealworms, and providing high-quality royal bamboo grass seeds, the company carries out ecological breeding technology training for the whole country. I don't know if this company is good or not, but the company's CEO has been on the first-class science and technology park program, which should be very powerful.

3. The cost of investing one acre of land for cage culture loach is 25,750 yuan. The specific cost first depends on the cost of a cage: 60 yuan for a cage; 20 catties of wild loaches need to be purchased, totaling 200 yuan; After 4-6 months of feeding, the weight gain is 4 6 times, at least up to 80 catties, each weight gain costs 4 yuan feed cost, the total feed cost is 240 yuan, if a large number of earthworms bred by themselves can reduce the cost by 20%; The cost of medicine is 15 yuan; The above totals 515 yuan.

The profit of raising loaches is still quite high. But the premise is that you have certain conditions to raise him. For example, you have a pond yourself.

If you want to raise loaches well. You also need that kind of indoor farming. This makes it more costly.

If it's just stocking, a large pond is sufficient, but this doesn't guarantee production.

The most important thing is the cost of loach seedlings and ponds, and the rest is the later management cost.

The largest loach in <> is about 30 centimeters long and weighs 500 grams.

Loach is known as the "ginseng of water" and is found all over southern China, and it is not common in the north, but it is also distributed everywhere. It can be harvested all year round, most often in summer, and after the loaches are caught, they can be used fresh or dried. Loaches live in lakes and ponds, and are small in size, only.

Three or four inches long. It is round, short, with small scales under its skin, blue and black, and covered in its own mucus, making it too slippery to hold.

Loach is a kind of fish with high nutritional value, it is different from other fish, no matter the appearance, body shape, life habits are different, it is a special loach. The body is elongated, and the anterior segment is slightly cylindrical. Posterior lateral flattening, abdomen rounded, head small, mouth small, lower, horseshoe-shaped.

The eyes are small and there are no under-eye stingers. 5 pairs are required. The scales are extremely small, rounded, and buried under the skin.

The dorsal and flanks of the body are grayish-black, with many small black spots on the whole, many black spots on the head and various fins, the spots on the dorsal fin and caudal fin membrane are arranged in rows, and there is a distinct black spot at the base of the caudal peduncle. The other fins are grayish-white. Loaches are widely distributed in China, Japan, Korea, Russia and India along the Asian coast, and can be eaten and used in medicine.

The answer is that the reason why loaches don't grow as big as fish is because of the genetic limitations of the species.

The loach is not as big as the fish trousers because the genes of the species limit the growth of the individual loach, and there is also the variety of loaches, the large loach of the same age, the female is larger and longer. There are also loach varieties, and some loaches are originally small, such as real loaches.

The main thing is the difference in loach farming methods! There is a difference between wild loaches and farmed ones.

The differences between farmed loaches and wild loaches are as follows:

First, artificial seedlings have strong adaptability.

Since the date of hatching, artificial loach seedlings have grown in artificially designed breeding sites and have strong adaptability; Wild loaches, on the other hand, are wild and unrestrained in front of the sails, and it is difficult to adapt to the fixed and narrow space of the farm.

Second, the state sends artificial seedlings to eat quickly.

Artificial seedlings begin to eat artificially cultivated feed from hatching, so they eat quickly and are easy to absorb; And wild seedlings, accustomed to eating all kinds of omnivorous, suddenly eat artificial feed, need a long adaptation process, when the adaptation of the sedan chair, in fact, has missed the loach growth of the first time.

It mainly depends on the growth environment. The largest loach is about 40 cm.

The whole body is slippery, and when I eat it, I don't take out the feces and intestines, and I just blow it up alive, which is cruel and disgusting! I never eat it.

Loaches are not raised on mud.

Loaches are omnivorous, and the juvenile fish feed on animal bait and feed on zooplankton, midges larvae, silk earthworms, etc. When it grows up, the range of bait expands, and in addition to eating a variety of insects, it can also feed on filamentous algae, plant roots, stems, leaves and humus. Adult loaches feed mainly on plant foods.

Generally, it is mostly nocturnal feeding.

Loaches are not very picky about their food requirements, sediment, colony, and organic detritus in the water are their food, and the bait organisms that feed are: diatoms, green algae, cyanobacteria, euglena, yellow algae, protozoa, cladopods, flexopods and rotifers.

The raised loaches are generally fed with wheat bran, rice bran, peanut cake, soybean cake, vegetable cake, earthworm, fly maggot and duckweed and other plant feeds, with a small amount of fishmeal, silkworm pupa, etc.

When the season is cold, the water body dries up, and the loaches burrow into the soil, relying on a small amount of water to keep ** from drying out, and relying on intestinal respiration to maintain life. When the tide rose the following year, he went out again. Because the loach's ability to tolerate low dissolved oxygen is much higher than that of ordinary fish, it has a longer survival time after leaving the water.

In a dry bucket, juvenile loaches with a total length of 4-5 cm can survive for 1 hour, while adults with a total length of 12 cm can survive for 6 hours and are still functioning normally when they are put back in the water.
