The scientific name Siniperca chuatsi, also known as guppy, perch guppy. In fish taxonomy belongs to the perch-shaped order, Siniperca genus. Among them, the warbler stiletto is the fastest growing. Cinnamon fish meat thick solid, delicious flavor, rich in protein, meat spines, nutrient-rich, is a delicacy on the table. The body is taller and laterally flattened, with a bulging back. The mouth is large, and the lower jaw is obviously longer than the upper jaw. The upper and lower jaws, plow bone, and mouth cover bone have small teeth of different sizes, and the back edge of the front gill cover bone is serrated, with 4 large spines on the lower edge; the back edge of the back gill cover bone has 2 large spines. Head scaly, scales minute; lateral line curved upward along dorsal arc. Dorsal fin in two parts, connected with each other, anterior part with hard spines, posterior part with soft fin rays. Body yellowish-green, abdomen grayish-white, with irregular dark brown spots and patches on the side of the body; a narrow black band from the end of the muzzle across the eye socket to the anterior and inferior part of the dorsal fin.

Chiniperca chuatsi generally inhabits still or slow-flowing water bodies, especially in lakes with lush aquatic grasses, where it is most abundant. They are not very active in winter, often overwintering in deep water, and generally do not stop feeding altogether. When the weather turns warm in the spring, it swims to the shallow water along the coast to feed; at this time, both male and female fish have the habit of lying on their sides in the lake bottom depression during the day, and at night they move and feed in the water plants. Mainly feed on other fish, January-February feeding is poor, June-July is the most vigorous, the intensity of feeding slightly decreased during the reproductive period. Siniperca chuatsi usually grows to the age of 2, in the northeast must be until the age of 3 to reach sexual maturity, the parent fish in May-July clusters at night in the gentle running water environment to spawn. June-July is the peak period of spawning, the amount of pregnant eggs for 3-20 million.

There are two species of Siniperca chuatsi, which are very similar in appearance, but the difference lies in the following: the gill rakers of S. chuatsi (English name: Mandarinfish , Aukua) are 7, the eyes are smaller, the head length is 5.3-8.1 times of the diameter of the eye, the maxilla reaches to the underside of the eye after the posterior edge of the eye, the lateral line of scales is 110-142, and there are scales on the lower part of the cheeks, and the pylorus pendant is 198-440. 440. On the other hand, S. kneri (English name: Bigeye mandarinfish) has gill rakers of 6, larger eyes, head length 4.7-5.1 times the diameter of the eyes, maxillae reaching only to the underside before the posterior margin of the eyes, lateral line scales of 85-98, buccal area not scaled, and 74-98 pyloric pituitary. Siniperca chuatsi grows fast, large individuals, commonly 2-2.5 kilograms, the largest individual weight up to 50 kilograms; big-eyed Siniperca chuatsi grows slowly, the individual is smaller, the largest individual can grow to weigh 2 kilograms.

Chiniperca chuatsi is widely distributed in the rivers and lakes of the eastern plains of China. The natural yield is quite high. The meat is white, tender and flavorful, without small spines, and rich in protein. Each 100 grams of edible portion contains 15.5-19.3 grams of protein, 0.4-3.5 grams of fat, 78-109 kilocalories of calories, 79-206 milligrams of calcium, 107-143 milligrams of phosphorus, 0.7-5.6 milligrams of iron, 0.01 milligrams of thiamine, 0.10 milligrams of riboflavin, and 1.9 milligrams of niacin. Siniperca chuatsi has been classified as one of the most valuable fish since ancient times. siniperca chuatsi was found among the funerary objects in the Mawangdui Han Tomb excavated in 1972! Siniperca chuatsi has many clusters of pyloric droops, commonly known as cinnamon fish, and its flavor is fragrant, fresh and crispy, so it can be said that "if there is Siniperca chuatsi on the table, even the paws of bears can be given up". It is worth noting that the 12 dorsal fin spines, 3 anal fin spines and 2 ventral fin spines of Mandarin fish have poisonous glands, which cause severe swelling and pain when stabbed, resulting in fever and chills, which is one of the most severe stabbing pains in freshwater venomous fish. Special care should be taken when catching and dissecting Mandarin fish.

Chinese chuatsi fish meat is sweet, flat, non-toxic, with the effect of tonifying the deficiency, benefit the spleen and stomach. Its tail can be used to treat soft boils in children, and its gall can be used to treat fish bones in the throat.

1) Fishing gear. Hand pole (5.4-6.3 meters) and bamboo wheel rod is good. Sea rod can also be used properly. Fishing line diameter 0.25-0.3 millimeters, sea rod fishing line can be thicker, hooks with 5 or 6 long shank arch back white fox hooks, without floating. The pendant should be light, generally 8-10 grams, spherical lead pendant is the best. The line should be long, 0.6-1 meters longer than the rod.

(2) bait. Live shrimp and live fish as bait. Live shrimp can be purchased locally to fishermen, 3-5 cm long the best, with bamboo shrimp cage or plastic gauze sewn into a cylinder, the size of the hand can loosely probe the shrimp appropriate, loaded with shrimp and raised in the river water. With the shrimp two pincers off, with the tip of the hook along the longitudinal axis of the shrimp body into the back of the shrimp to hang on. Attention should not be too deep, so as not to hurt the internal organs caused by death.

(3) fishing method.

Hand rod fishing method: hang a good bait, you can directly shake the wrist cast, you can also hold a lead pendant to throw the bait hook. The fishing spot is usually the calm backwaters between the waves. The bait rises and falls under the top of the waves, luring Mandarin fish to chase and feed. Keep the rod in your hand, pay attention to the direction of the line being impelled by the water and waves, and pull your wrist gently from time to time to avoid hooks hanging on the rocky reefs under the water. When you feel a peck at the tip of the rod, you should quickly shake your wrist to lift the rod when it vibrates. The timing of the rod must be well grasped, too early, such as the point of action does not play, the hook is not into the mouth of the fish; too late, the bait hook into the throat is too deep and very difficult to take out. When you take the hook, pay attention to your fingers not to be stabbed. Catch fish with your hand to a tight grip, otherwise the Mandarin fish back eel poisonous spines, not only unbearable pain, but also very easy to inflammation and redness.

Wheel rod fishing: bamboo wheel rod is faster than the sea rod, the general body is shorter (1-1.5 meters), and the toughness is far better than the sea rod. Hooks with larger square hooks, the Department of single hook; pendant can be slightly heavier than the pendant rod, 15 grams or so, with a small live fish as bait (to minnow as well). Use the hook to hang on the palate of the minnow, throw the bait hook to the rapid waves, slowly release the line with the waves, and frequently pull back. The purpose is to increase the chances of big Mandarin fish chasing food, in addition to avoid hooks hanging underwater rocks or other debris; once the rod tip weight and accompanied by a sense of popping vibration, you should immediately lift your hand and pull the wheel rod, the fish hooked firmly, and then try to pull to reel in the line. If you can not pull, that is the fish into the cavern, there is no need to be impatient, you can try to pull the left and right direction, lure the fish out of the hole. If the fish want to line, then appropriate release line, not hard fight. When the fish can pull, then turn the reel, bring the fish to the shore in shallow water, and use the net to catch fish. Mandarin fish caught with this method are generally larger.

Sea Rod Fishing: Basically, use the wheel rod fishing method. However, the hooks can be used as string hooks, and the pendant with a flat pendant is good. The bait can be shrimp and minnows at the same time. The bait hook is thrown out of the water a moment, should be against the water line, luring the fish to catch up with the bait hook. Sea rod is easy to hang rocks and other obstacles, easy to cause folding rod, broken line, running fish, is its shortcomings.
