The first kind: Sesame saury
This fish has a slightly flat head, scaly skin and irregular black spots. Like black sesame, fish is as long and narrow as a sword. When the fish is cooked, it smells like sesame, hence the name Sesame Sword. Sesame saury is one of the best freshwater fish because of its fat meat and rich nutrition. In rural areas, people often use sesame saury to make soup for the elderly or children, which is beneficial to the spleen and stomach, intelligence and brain.
Sesame saury is a kind of cold-water fish, which requires extremely high water quality. It likes to thrive in caves or underground rivers, so its number is very small. In the market, sesame swordfish sells for more than 400 yuan a catty.
The second kind: rock climbing fish
Rock climbing fish is a kind of freshwater fish that lives in mountain streams, and likes streams with fast-flowing rocks and sediments. This kind of fish has a flat head wider than fish, a long beard and a scaly brown dorsal fin, which is mistaken for Pelteobagrus fulvidraco by unfamiliar people. Rock climbers like to lie on the rocks under the water and crawl with their bellies pressed against the rocks. Rock climbing fish is fresh and tender, delicious, comparable to oysters, so it has become the object of hunting. Rock climbing fish grow slowly in the wild, and now they sell for 1000 yuan a catty.
The third kind: oxtail fish
This is a precious cold-water fish that lives in Heilongjiang in the northeast of China. It is also called Lucky Fish and Horse Hook, and its scientific name is Wusuli [wéi]. The head of oxtail fish is flat, the fish body is scaly, round, smooth and light yellow, and gradually slender from beginning to end. The fish body can reach 1 m, like the tail of a cow. Oxtail fish is a rare wild fish unique to Heilongjiang river system, with few fishbones and delicate and delicious meat, which costs more than 200 yuan a catty.

The fourth kind: flower fish
Lotus fish is a species of tuanjie carp, also called lotus carp. The fish body is small, the golden scales are closely arranged, the skin is slightly transparent, and the appearance is fresh and beautiful. Flower fish grow in rice fields in the south and prey on insects and aquatic plants in rice fields. When rice blooms, it is also called rice-scented fish when it is swallowed in the water. The meat of flower fish has the clear fragrance of flowers, and the meat is tender and odorless. Nowadays, fish are also raised in rice fields in many places, but it is a bit difficult for many ordinary carp or crucian carp to eat delicious flower fish instead of traditional carp.
The fifth kind: shrimp.
Speaking of crayfish, I believe many people are familiar with it and like it very much. Crayfish, formerly known as Procambarus clarkii, is an invasive species. There is a delicious food in Changbai Mountain in Northeast China that is very similar to crayfish. You may not know much about it and have eaten it. This kind of shrimp is very similar to the lobster in the ocean in appearance. It is harsh on the environment and only grows in cold water streams with clear water quality. It is a unique protozoan species in China, commonly known as bighead shrimp and lobster shrimp. Lobster and shrimp are delicate and delicious. Lobster and shrimp are very sensitive to changes in the ecological environment. Once the waters where it lives are polluted, it will disappear. If you want to eat wild lobster and shrimp now, you may not be able to buy it if you have money.

The shell of a snail is dark green, with a long cone and the size of a fingernail. Snails grow in fast-flowing streams or potholes and attach themselves to stones in the water.
