Rouge fish, also known as yellow chops, blood chops, noodle chops, bottom mud fish, plain sailing, burning oysters, wood leaf plates, etc., is a common freshwater fish in the Yangtze River system, which is artificially farmed because of its rich nutrition and ornamental value.

Rouge fish, also known as yellow platoon, blood platoon, etc., is a national second-class rare and protected fish, growing in the Yangtze River system of China. It is highly dependent on the wild water environment, and it is bound to die if it is fished out of the Yangtze River.

Is rouge fish a protected animal? rouge fish are vulnerable. It is a national Ⅱ protected wild animal in China. The number of individuals in the wild state of rouge fish is decreasing year by year.

What to eat? Fish shit?

Rouge fish prefer to move in the middle and bottom of the water body and are not tolerant to hypoxia. Its body is peculiar, especially the young fish have a unique figure, swim quietly, and will change their body color with mood changes; they are omnivorous animals that eat frequently, regardless of their food status, and their foods include harvest shrimp, red earthworms and vegetables. Carmine is an egg-laying animal, but it has not been successfully bred in an aquarium environment. Nodules appear on the head and fins of male fish as they approach the female.

Bait and feeding: the feeding effect of water maggot slough is the best. In the actual production, according to the feed source, the local snail clam meat, small fish and shrimp, livestock and poultry viscera or artificial cultivation of terrestrial earthworms, fly maggots and other fresh bait can be used to reduce the cost. Large-scale breeding can be domesticated and ingested artificial formula feed. According to its high requirements for crude protein and crude fat, artificial formula feed can be prepared by itself. Some units mix minced animal meat with feed from a wide range of sources, such as wheat bran, soybean flour and rice bran, for a long time, and the effect is also ideal.

The daily feeding rate varies according to different seasons. Generally, the daily feed quantity from April to May is according to body weight 3%, 5%, 5%, June, August, September, October, September, October, November, November, December, November, November, November, If the feed is fresh wet feed, it will be increased by 20.3%. In practice, the daily feeding amount should also be flexibly mastered according to the weather, water temperature, dissolved oxygen and pond fish intake in accordance with the "four fixed" principles to ensure that they are well-balanced, well-fed and full.

The latest market price:

According to the price situation in different cities, the average cochineal fish is about 30-40 yuan per catty. If it is wild, it will cost more than 100 yuan. If it is a tourist area, it will cost about 300 to 400 yuan.

Rouge fish used to be edible fish species, now it is the second class protected animals in the country, and the number is even less than some first class protected animals, so it is necessary to strengthen the protection. At present, all the fish sold on the market are young fish, commonly known as "plain sailing", which means good luck. Because of its large size and rare number after adulthood, most of the fish were sent to the Yangtze River and Minjiang River basins to be released.

Culture techniques:

1. Pond conditions: except for fertilizer ponds and ponds where drought and waterlogging are not guaranteed, general culture ponds can be used to raise carmine fish. Before releasing fish species, the pond must be cleaned to remove too much silt and leave 2o-25cm; reinforce the slope and ridge of the pond, plug loopholes; improve the intake and drainage system, pond inlet and discharge requires solid and reliable anti-escape facilities, can effectively prevent the escape of farmed fish and wild miscellaneous fish into people. In addition, in the process of breeding, it is required that the water source is adequate, the water quality is fresh, and it is best equipped with mechanical equipment such as increasing oxygen and irrigation.

2. Fish stocking: it should be completed before March, the size of the fish species should be more than 50 grams, and the size of the fish species in the same pond should be uniform as far as possible. There are 400-600 large-size fish species per mu. Another 100 to 200 silver carp and a small amount of grass carp, carp and so on. Depending on the situation, another 800 to 1000 carmine summer flower fingerlings can be raised. When mixed culture, take other fish as the main fish, rouge fish as a kind of bottom matching fish, put 100-200 large-size rouge species per mu. Due to the mild nature, benthic and carnivorous characteristics of cochineal fish, it should not be cultured in the same pond with common carp, crucian carp or other fierce carnivorous fish.

3. Bait and feeding: the feeding effect of water maggot slough is the best. In the actual production, according to the feed source, the local snail clam meat, small fish and shrimp, livestock and poultry viscera or artificial cultivation of terrestrial earthworms, fly maggots and other fresh bait can be used to reduce the cost. Large-scale breeding can be domesticated and ingested artificial formula feed. According to its high requirements for crude protein and crude fat, artificial formula feed can be prepared by itself. Some units mix minced animal meat with feed from a wide range of sources, such as wheat bran, soybean flour and rice bran, for a long time, and the effect is also ideal.

The daily feeding rate varies according to different seasons. Generally, the daily feed volume from April to May is 3-5% of body weight, 5-8% from June to August, 3-5% from September to November, 1-2% from November to December, and a small amount from November to March. If the feed is fresh wet feed, it will be increased by 2-3% accordingly. In practice, the daily feeding amount should also be flexibly mastered according to the weather, water temperature, dissolved oxygen and pond fish intake in accordance with the "four fixed" principles to ensure that they are well-balanced, well-fed and full.

4. Daily management:

(l) patrolling ponds frequently: at least 3 times a day, observe their feeding, swimming and pool water changes, check intake and drainage facilities, especially in times of sudden changes in weather and storms, step up inspection and deal with problems in a timely manner. Wash the bait table frequently to remove residual bait, dirt and dead fish from the water every day to prevent water pollution.

(2) Water quality management: to change water frequently, under normal circumstances, one small change per week, change injection 0.3; half a month big change, change injection 2CP3. With the fish growing up and the water quality getting fatter, appropriately increasing the number of water changes, the water should be changed every day in the high temperature season, and the aerator should be turned on regularly to keep the dissolved oxygen in the pool water rich and transparent above 40 cm, which can promote the appetite of raising fish and reduce the incidence of disease. in addition, conditional farmers regularly sprinkle disinfection drugs such as quicklime and bleach to regulate the water body. It is also advisable to apply modifiers such as photosynthetic bacteria and EM bacteria to the pond, which is very effective in improving the oxygen supply at the bottom of the pond and improving the water environment.
