How do you make delicious Suancai Yu (pickled mustard green fish soup)? A five-step cooking method to help you make it easily
Ingredients: Grass carp or common carp, grass carp is best, about one and a half jin in weight is better. One head of pickled mustard greens (the reason I say one head is because pickled mustard greens made from kohlrabi are generally pickled one head at a time). Steps: 1. After cleaning the fish, remove the fish head, slice the fish meat off and cut it into small slices. Chop the fish bones into small sections. If the pot is not big, you can keep the fish head for making fish head soup later. If the pot is big enough, you can cook the fish head together as well. 2.

Feeding Methods and Technical Key Points for Juvenile Angelfish
Feed the fry opening food 5-8 hours after they leave the board and swim freely; feed them infusoria or brine shrimp nauplii. Feeding egg yolk water is no good; the fry do not like to eat it, and it fouls the water. Changing the water is unrealistic; you will find it simply cannot be done. The first feeding should be a small amount, just enough for every fish to get some. Feeding too much causes indigestion and instead kills the fish. After the first feeding, wait about 8 hours before the second feeding, so the fry have ample time to digest, adapt, and empty the "yolk water (milky mucus)" in their bellies. After that it is easy to manage; you just need to feed three times a day.

What technical points must be mastered for polyculture of fish, shrimp, ricefield eel, loach, crab, and crayfish?
1. Pond selection. The pond is nearly square, with surrounding ditches 8 m wide and 0.6 m-0.8 m deep, the beach surface can be raised with water to 1.2 m, the pond bottom is sandy soil, the water source and water quality are good, and water inlet and drainage facilities are complete. On the inner side of the pond, fine-mesh polyethylene netting is buried in the soil to prevent ricefield eels, loaches, red swamp crayfish, crabs, etc. from burrowing. Asbestos tiles are used as an escape-prevention wall. The pond must be strictly disinfected with quicklime and other drugs, sufficient base fertilizer applied, natural feed cultivated, and aquatic plants such as tarragon and tape grass planted. Around Qingming, a large amount of live river snails

Introduction to Common Fish Medications, Part 3
II. Nitrofurans Nitrofurans are a class of synthetic broad-spectrum antibacterial drugs with many varieties, but only 3 to 4 are used for aquatic disease prevention and treatment. The basic structure of nitrofuran drugs is a furan ring with a nitro group attached at the fifth carbon atom. They have strong antibacterial effects; at low concentrations, they can inhibit the reproduction of many Gram-positive and Gram-negative bacteria; at high concentrations, they have bactericidal effects. Generally, bacteria do not easily develop resistance to nitrofuran drugs. Even bacteria resistant to sulfonamides and antibiotics remain relatively sensitive to nitrofuran drugs. However, nitrofuran drugs are poorly absorbed in the body and are easily and rapidly destroyed after absorption, often failing to reach effective blood antibacterial concentrations in the blood. Only in the intestinal tract can they maintain effective action, so they have a good effect in preventing and treating bacterial intestinal infections in fish. In addition, according to recent reports, nitrofuran drugs have carcinogenic effects, so their use has been restricted. At the same time, long-term use of these drugs can cause liver and kidney damage in fish.

Detailed Explanation of the Oil-Immersion Smoking Processing Technology for Canned Ribbonfish
(1) Raw material handling: Remove the fins, tail, and belly meat from fresh or frozen (thawed) ribbonfish. Control the tail width at 2.5-3 cm. Blanch in hot water at 70-75°C for 2-6 s, scrape off the scales, cut off the head, and wash away blood, black membrane, and impurities with running water. Split into fillets, remove the backbone, and rinse again with running water for 40 min to remove blood. (2) Salting: Immerse the fillets in 4.5-5.5°B6 brine for salting. The ratio of fillets to brine is 1:2, and the salting time is 20 min. (

What practical cold-proof measures are there for fish and soft-shelled turtle farming
1. Pond selection Choose a deep-water (over 2 m) pond sheltered from the wind and facing the sun for natural overwintering. The water in the overwintering pond should not remain stagnant for long periods; usually replace part of the pond water every 20 to 30 days, each time replacing 1/4 to 1/5 of the total pond water, to prevent pond water contamination. 2. Set up windbreak walls and cold-shelter holes On the north side of the pond, a 2 m high windbreak barrier can be built with straw or earth, and on the east and west sides build earthen walls sloping toward the south, forming a winnowing-basket shape, to reduce attacks by the north wind, so that when a cold wave strikes the water temperature will not drop noticeably. Around the pond, drainage

Brewing wine from fish gives exceptionally high nutrition; the nutritional value of fish wine should not be underestimated
People who drink alcohol all know that fish is a delicious accompaniment to wine, yet few people know that fish itself can also be used to brew wine, and its nutritional value is several times higher than that of ordinary wine. In China's alcohol market, fish wine produced in Dalian has attracted people's attention. Dalian people not only love seafood, but are also good at finding new ways to enjoy seafood products. The fish wine, which can be called a unique wonder of China, was developed through the dedicated research of Dalian native Sun Keman. The alcohol industry's authorities evaluate fish wine as follows: it has changed China's traditional winemaking process of several thousand years and opened up a new world for the global alcohol industry

Correct Methods and Precautions for Mixing Fishery Drugs
With the increase in the variety of fish species stocked in polyculture ponds and the rise in stocking density, the chance of different fish diseases occurring simultaneously in different fish in the pond has greatly increased. In general, the effect of using a single fishery drug is poor, while the method of mixing fishery drugs can significantly improve the therapeutic effect. 1. Principles of mixing. Do not affect the chemical stability of the active ingredients of the drugs; do not increase toxicity, and the ideal effect is to increase efficacy without increasing toxicity; the drug effects should be reasonably matched and complement each other's advantages; do not increase the cost of medication. 2. Precautions
