The dorsal edge of the head is low, and its posterior end has spikes. The eye is large, high, widely spaced, with 3 blunt spines on the lower edge of the orbital bone, 5 spines under the anterior gill cap, and 2 spines on the main gill cap. The dorsal fin is continuous, with a missing in the middle, with 13 fin spines in the anterior part; the pectoral fin is larger; the caudal fin is nearly rounded; the fin and ventral fin are developed, with 3 spines. The whole body is covered with fine round scales, except for the two jaws, the front bone and the gill cover without scales. The dorsal side of the body is dark brown and the abdomen is off-white.

Distribution range
Black catfish is a warm water demersal fish, which is distributed in the warm temperate zone of the East China Sea, the Yellow Sea and the Bohai Sea in China. It usually lives in areas such as gravel, rock reefs, artificial rockfills, shipwreck seaweeds, etc. on the seabed, and most of them inhabit reef crevices and caves.
Habits of life
There are two kinds of black catfish, "sitting fish" that do not swim long distances, who live near the cave all year round, and "wandering fish" that migrate far away, and the former is smaller. Except in winter, black annchovies can be caught all year round. Late autumn and early winter are the golden season for fishing, especially when fish flocks move to deep waters during the light snow in late November. Black catfish have a diurnal and nocturnal habit, and their main food is fish, shrimp, sand silkworms, crustaceans, tube cockroaches and so on.
Feeding habits
Black carp is a ferocious carnivorous, mainly feeding on trash fish and shrimp, and also eats a large amount of cephalopods and shellfish.
Fishing
Fishing tackle: Most of the fishing black bass fishing boats and rafts. Taking boat fishing as an example, the fishing rod is usually 2-3.6 meters in the hard sea fishing rod, the rod should not be too long, too long is inconvenient to use, it should not be too short, too short is thrown and the sensitivity of the fish is poor. Winding wheels can be selected according to personal use habits, and rotary winding wheels or fork tooth winding wheels can be selected. Many anglers in Qingdao, Yantai, Shandong Province, for sea fishing, are still accustomed to using fork tooth winding wheels, because of their proficiency in throwing far and the accuracy of throwing accuracy is no less than that of the spinning winding wheel, and the operation is convenient, there is the flexibility of the fish wheel and the benefits of being pulled without losing the rod. The main line uses monofilament nylon wire, the storage line is more than 100 meters, the diameter is 0.50-0.60 mm (8-12); the diameter of the brain line is 0.35-0.40 mm (4.5-6), the length is 30-50 cm, in the area where it is easy to hook, it is shorter, and the fishing point can be longer on the flat seabed, which should be selected according to the field and personal fishing experience. Fishing hooks usually use a long handle hook with barbed spines on the hook handle, the advantage is that the hook is convenient to pick, and it is not easy to fall off when the bait is thrown far away, and it is advisable to choose a hook of 15-18 (the width of the hook door is 0.95-1.1 cm). Most of the lead drops use cheap discarded falls, the weight of the fall depends on the current and depth of the fishing ground, the following water obstruction, can sink quickly as the principle, the bottom complex fishing point should be prepared for the fall. In addition, there are several pieces of hand line fishing gear, vertical application in the leisure time of throwing fishing, sometimes there will be unexpected gains, some people jokingly called "side income", fishing should be based on the specific situation, when needed, special hand line fishing is also a good method.
Fishing bait: the bait of black catfish is very extensive, all the bait that fish can use can be used for fishing, such as sand silkworm red worms, green worms, grass tube worms, shellfish flying clams, seeds, purple shellfish, shrimp frontal shrimp, small white shrimp, shrimp meat, fish called gu fish, six-line fish, mackerel, cockroach tube slugs, squid, squid, etc., as well as poultry offal, meat can be used as fishing bait. It can be seen that fishing for black catfish does not have to spend too much energy to prepare bait, as long as you bring a small amount of insects or shrimp meat when fishing, first catch a few fish called gu fish or other fish that are easy to catch, and then cut these fish into long strips, use the fishing hook to randomly hook the front end of the fish meat strip, expose the tip of the hook, you can throw fishing. When the black catfish feed on the fish, most of the fishing hooks are in the mouth, the bait is still exposed, and the bait can be used again after picking the fish. If there is a shortage of bait in the middle, you can also cut the black catfish into strips of meat as bait, and the effect is also quite good
Fishing spots: Black bass usually inhabit caves, rock bottoms, cave crevices, shipwrecks, sediments and groups of rocky reefs and fragments around islands. These areas are relatively stable habitats for blackfish and are of course ideal fishing spots. It is easier to find fishing spots around the island, but the fishing spots that are easy to find are often patronized, and there are fewer monks and more porridge. To this end, we should constantly search for and discover new fishing spots for black catfish. Look for fishing spots in places that usually look inconspicuous, in little-known sediments, little-known shipwrecks, hidden deep reefs, hard textures, etc. Although it takes a little longer to find a new fishing spot, sometimes even empty-handed, this pursuit is also one of the pleasures of fishing, and there will be a time of bitterness.
Fishing method: A common fishing method used in tossing and vertical fishing with a straight line. Throwing fishing is suitable for reef shore and boat fishing, throwing the fishing group to the distant fishing point, and after landing at the bottom, the fishing rod is placed on the boat board or on the flat part of the reef, and the fish can be hooked. When using this fishing method, it is usually not easy to pull the bait on the fishing point, until the fishing signal appears, the fishing line is straightened or the rod tip is bent down, and the rod is lifted rapidly to lift the fish away from the bottom layer and then close the line to avoid hanging the bottom line. The whole process should be done in one go. Another method is the jump fishing method, the so-called jump type is to throw the fishing group to the fishing point, a drop to the bottom to lift, and then drop the bottom and then lift it, forming a jump type of recycling, leading the fish to the hook. Jumping often has a situation of halfway jam, at this time can not be pulled hard, such as the fish has been hooked, simply put the rod and wait for the fish to pull in the opposite direction and then drum up the line. Single or multiple hooks, falling hooks or falling hooks can be used for handline fishing, which should be selected according to the specific situation. Its main way is to put it into the water vertically from the edge of the boat, and the fishing depth can be from the bottom to the middle and upper layers, and the transformation is very flexible, and the fishing personnel are well known. In fishing, if you encounter a fish with large individuals and rapid water depth, the fishing rod can hardly be used well, and the use of hand line fishing is the first choice. The spines and fins of the black catfish are poisonous, once stabbed, the poisonous blood of the wound should be immediately squeezed out, and cleaned with seawater, and then the thorn will be rubbed back and forth on the mucus of the fish body several times, and slowly knead the wound with the hand, the symptoms will soon be alleviated and disappeared.
Lua
It is best to use a lead hook and a capuchin maggot fishing set, and you can use throwing, swinging and other methods to throw bait into the reef crevices and seagrasses. The simplest way is to recycle at a uniform speed after throwing, because the punctuation environment is more complex, more fishing set hanging bottom will occur, so it is necessary to control the speed of recovery to avoid the bottom of the fishing set. The punctuation of Lua's blackfish doesn't have to be far away, and a lot of good punctuation is at your feet.
The attack of the black catfish is more ferocious, and even small individual fish will sometimes bite down on the soft bait that cannot be swallowed. Its bait attacks often occur more suddenly, biting the fake bait will turn around and drag into the crevice of the stone where it lives, so when it finds a fish in the middle of the hook, it must decisively raise the rod to lift the fish to the upper water and quickly recover to lift the fish out of the water. The black squid out of the water is more honest and does not flutter much on the hook, but it will be more tossed when placed on the ground. When picking the hook, be very careful not to be stabbed by the fins or the spikes on the gills of the fish, many marine fish have poisonous spikes, which will be severe pain and redness of the wound, and it will take several hours to resolve. The correct way to remove the hook is to use a fish controller to clamp the jaw of the fish and then use Lua tongs or to pick the hook with hemostatic forceps. Experienced anglers can also pinch the jaw of the fish with their thumbs and forefingers and pick up the hook.
