How much is the market price of cold water fine scale fish per jin? What's the value? How do you raise it? How do you cook it?

Fine-scale fish is a rare cold-water fish, which can be seen in places where the water quality is clear and the current is fast. Its nutritional value is high, so the price is relatively expensive. How much is the market price of fine-scale fish per jin? What's the value? How do you raise it? How do you cook it?

The latest market price:

Small-scale fish is a state-protected animal, although artificial breeding has been successful, but it is still an endangered species, so the price will be a little expensive. Generally speaking, its price is at least about 100 yuan per jin. However, it is estimated that most of these endangered species have a price but no market.

Economic value:

Fine scale fish has delicate meat and high fat content, so it can be used as a new culture object.

Fine scale fish is a national second-class protected aquatic wild animal, which has important academic research value in ichthyology and zoogeography. There were a large number of fine-scale fish before 1980, but due to human economic activities, overfishing and other reasons, fine-scale fish decreased greatly and were on the verge of extinction.

Qinling fine scale salmon has fast growth, delicate meat, no intermuscular thorns, delicious taste, has the function of preventing thrombosis and speeding up wound healing, also known as brain gold, with high nutritional value. The Song Dynasty is the tribute of the imperial court. Superior to rainbow trout produced in California, USA, rainbow trout was listed as one of the precious resources in Dingxi in 1981.

Culture techniques:

1. Larval fish culture. The culture container is a glass fiber reinforced plastic parallel trough (40 cm × 30 cm × 20 cm), which is cultured in running water. The influent flow rate is 1820 liters / min, and a 100 watt fluorescent lamp is set 60 cm above the water surface. The stocking density is 10,000 per trough. The total length of newly hatched fine scale fish larvae is 14-16 mm.

2. Juvenile fish cultivation. The juvenile fish pond is 10 meters long, 2 meters wide and 30 centimeters deep. Small scale fish larvae gradually float up and swim in the water after 2 / 3 of the yolk sac is absorbed. The stocking density of juvenile fish was 6000 / m2 in parallel trough and 3000 / m2 in juvenile pond. When the floating rate of juvenile fish reaches more than 50%, the opening feed should be fed with artificial formula feed. The artificial formula feed of juvenile fish with 45% crude egg content can be selected, but the fat content should be more than 12%. The particle size of feed is 0.3 mm and 0.5 mm.

3. Fish fingerling cultivation. Adopt the cultivation of the running pool, the running pool adopts the cement pool, the area of the single pool is 3090 square meters, the depth of the pool is 6080 centimeters, and the water depth is 50 centimeters. The pool is 1.2 to 2.5 meters wide. The slope of the bottom of the pool is 2 ∶ 1000mm 5 ∶ 1000. The water flow rate of the running pool is 100,300 liters per minute, keeping the water depth at 50 to 60 centimeters. The stocking density was adjusted according to the growth specification of fine scale fish. The stocking density of 5 grams of fish is generally 1000 fish / square meter; for fish of 10 grams, the stocking density is generally 800 fish / square meter; for fish of 20 grams, the stocking density is generally 600 fish / square meter; for fish of 30 grams, the stocking density is generally 500 fish / square meter.

4. Adult fish culture

① aquaculture: cement ponds are used. The cement pond is rectangular, with an area of 200 square meters, a depth of 100 cm and a water depth of 80 cm. The width of the pool is 6.67m, the length of the pool is 30m, and the slope ratio of the bottom is 12 ∶ 1000. The ponds are arranged in parallel. The source of water is groundwater with lower water temperature. The suitable water temperature for growth is 13-20 ℃, the optimum water temperature is 13-16 ℃, and the highest water temperature should not exceed 20 ℃. The pool water exchange rate should be more than 2 times per hour, and the flow rate should be kept at 0.02 ~ 0.16 m / s. Dissolved oxygen in water is more than 6 mg / L, and ammonia nitrogen should be controlled below 0.0075 mg / L. The stocking density is generally 150 fish / sq m for fingerlings of 20g / m2; for fingerling of 100g / m2, the stocking density is generally 150 ind / m2; for fingerling of 150g, the stocking density is generally 100 ind / m2; for fingerling of 200g, the stocking density is generally 75 ind / m2; for fingerling of 300g, the stocking density is generally 50 ind / m2.

② lake multiplication: choose the lake with dense aquatic plants (the coverage rate should be more than 90%), clear and transparent water body, no pollution, the highest water temperature in summer not more than 20 ℃, dissolved oxygen in water not less than 5 mg / L, the total amount of suspended matter in water not more than 15 mg / L, it is appropriate to release and multiply, and the water should also be rich in benthos, aquatic insects, small fish and shrimp and other bait organisms. Fine scale fish juvenile and 1-year-old fish species can be released. The size of juvenile fish should be 3 cm and 5 cm. The suitable stocking density is 10 ~ 30 tails / mu. The appropriate size of 1-year-old fish species is about 25 grams, and the stocking density is 5 fish / mu. Fine-scale fish have the habit of migrating to the depths of the river in late autumn and early winter, and fishing is usually carried out from late September to early October, otherwise the fine-scale fish will dive into the depths of the lake to survive the winter, which is very difficult to catch.

Practice introduction:

Braised Fine scale Fish in Brown Sauce

1. Remove the internal organs and scales of the fish, put a little oil in the pan, stir-fry the fish with spring onions and ginger, add cold water, heat for 2-3 hours after boiling, put salt, chicken essence and coriander out of the pan.

2. Remove the viscera and scales of the fish, add cold water to the casserole, add fish, spring onions and ginger, bring to the boil over low heat for 2-3 hours, add salt, chicken essence and coriander to the pot.

3. Wash about half a jin of fine scale fish, put in broth, add salt, soy sauce, sugar color, green onions, put big ingredients, cumin and pepper into cloth bags, simmer and simmer for about half an hour. Stewed fine scale fish white and tender, delicate and palatable. Clear stewed Zhe Luo fish is slightly the same as stewed fine-scale fish, with obvious erythema in the belly, beautiful color, fresh and tender palatability.

Steamed fine scale fish

1. Wash the fine scale fish, cut the flower knife, put the ginger into the fish and wrap it in plastic wrap.

Put it in the microwave, play for 6 minutes and choose the steamed fish menu. Cut the chives and put them on the surface of the fish.

3. Boil the oil and put in the soy sauce. Pour it into the fish while it is hot and you can eat it.
