Small live fish, mollusks and arthropods are widely used in marine fishing activities.

1. Nereis: Nereis is known as the "universal bait" for sea fishing and the "golden bait" hanging at sea;

1, rock worm: commonly known as "meat maggot". It is 20-35 cm long, with light blue or light green fluorescence in the front of the adult, nearly cylindrical flesh red in the trunk, light pink and flat in the tail, and thick and fluffy lateral lines on the side. It is quick in the warm season and runs away quickly. Living in the gap of the reef or the soil around the root of the reef does not require serious pollution and deep soil layer. The product quality is high in yellow soil and strongly weathered brittle rocks. The price of sea fishing is high in peak season. The whole insect weighs one kilogram in 240 yuan. Even if it is incomplete, the retail price is 160 yuan. Rock worms can survive for a day and a night when stored in the refrigerator. In addition, it can also be pickled, that is, the rock worms can be completely pickled, dried, mixed with refined salt, sealed and put into the freezer, which can be preserved for a long time. Fresh rock worms have the advantages of eye-catching color and strong fishy smell, and are the best in nereis bait. The disadvantage is that the abdominal cavity of fresh worms is enlarged, the body fluids are rich, and they don't like hooks. It's easy to part ways when the bait hook is thrown far away.

2. Nested Nereis: commonly known as "tube maggots" and "bagged Nereis". The diameter is slightly smaller than that of rock worms, and the maximum length is 50 cm. The head is cylindrical, the fluorescence is weak, and the trunk is obviously oblate. Habitat habits and body color marks are different from those of rock worms. Nereis weaves a tubular hiding place on the muddy beach with secretions and impurities, and its lower end communicates with the caves deep in the beach, forming a special living space with "fortresses" on the ground and "trenches" underground. Once disturbed, it will quickly flee to the depths of the beach to take refuge. There are obvious nodal stripes on the body surface. The price of Nested Nereis is kg 20 yuan, and the content of networms is low, so it is the top grade of Nereis bait. Nested nereis are easy to keep. It can be stored directly in the nereis box and refrigerator for more than four days and four nights. If the worms are sprayed with seawater regularly, it can be extended to one week. The use method is basically the same as that of rock worms.

3. Red Nereis and Green Nereis: commonly known as "sand maggots". The body length is between 5 and 10 cm. Nereis has strict requirements on various indexes of habitat, little water pollution and good soil permeability. The body surface of Nereis is milky white, light yellow and pink, and there are bright red lines extending from the head to the tail in the center of the back. Compared with the slender body, the lateral foot is relatively developed and strong, and the yield is scarce. Nereis is widely distributed, with high yield and loose requirements on water quality and habitat soil. The difference between Nereis and Nereis is that the body is thicker and slightly shorter than the former. The body surface of Nereis is light green, light yellow and light pink, and the color varies with different habitats. There is no obvious center line on the back, and the lateral feet are tight and small, which are rich along the Yellow Sea and Bohai Sea. At present, the price of Nereis in Dalian is about per kilogram 120 yuan, and that of Nereis is RMB 0.00 per kilogram/kloc-0. Even the price of artificially cultured Nereis has climbed to 80 yuan per kilogram. The preservation methods of the above-mentioned kinds of nereis are similar, which can be mixed with dry river sand and tasteless sawdust, or simply packed in nereis boxes with seaweed. Blue Nereis can survive for more than two days, and red Nereis can survive for four days without any problems. In the process of preservation, it is necessary to control excess water and sort out the injured pests and diseases. Most baits don't need to be segmented. They penetrate from head to tail, stab out from the other end, and a few stay outside the hook tip. The advantage of using the whole worm as bait is that the bait has strong affinity for the hook, and it squirms strongly after entering the water, which stimulates the fish's desire to hunt.

Second, small live fish: small live fish used for sea fishing is very common as bait, but due to the difficulty in breeding and preservation, the types available are limited, and small freshwater loach and small scaleless miscellaneous fish under mudflat rocks are economical and applicable, so they are widely used as bait;

1, Misgurnus anguillicaudatus: freshwater benthic scaleless fish, easy to raise, low in price, strong in vitality, and can keep swimming after entering the water. This is a very effective bait for catching fierce carnivorous fish, such as perch. When buying loach as bait, you should choose those who are strong with black back and yellow body fat. Misgurnus anguillicaudatus hook should penetrate into the upper jaw of bait fish and stab out from the front end of dorsal fin to avoid injury to internal organs and prolong the survival time of bait fish. The price of loach fish is about 16 yuan, which is an economical bait. Preservation method: raise in water or wrap with aquatic plants rich in water. When in use, choose one to roll in fine sand, which is convenient for hanging bait and saves time and labor.

2. Small miscellaneous fish: common scaleless fish under rocks in coastal shoals, including gobies, gobies, eels and so on. The body length is below 10 cm, and the minimum thickness is less than the sweater needle. Small miscellaneous fish can bite, but it is difficult to catch. Use and save as above.

Three: Meat: beef, mutton, pork, pigskin, chicken and various fish can be used as sea fishing bait after decomposition;

4. Corks: China squid (squid), octopus, octopus, octopus, octopus, octopus, octopus, oyster, sea rabbit, mussel and other marine mollusks can be used as bait for sea fishing. Except for small sea rabbits and peach octopuses whose individuals are less than 5 cm, they can be hooked as a whole, and generally need to be broken down into hooks. Squid meat is flexible, and the hook tip is not easy to pierce the fish lip when it is buried in the bait. When installing the hook, the hook tip should be exposed a little. The color of the axe and foot muscles of shellfish such as red clams is golden yellow or ruddy. It is a good bait to break and peel off the hard shell and then take the bait. Oysters and mussels are tender, delicious and juicy, and slightly salty water will be more hooked;

5. Arthropods: China prawns, grass prawns, Neopenaeus monodon, Gryllotalpa, tiger prawns and other shrimps are good baits for catching black snapper and perch. When in use, the head can be peeled and the shrimp meat can be used in sections. Can also be used as a whole, and can be pierced with shrimp head or shrimp tail when hanging bait. The commonly used crustacean bait for sea fishing is sea crab and hermit crab. When installing the hook, remove the crab cover and break the claws. The color of crab meat is white and moist, and the fresh crab yellow makes the sea eel irresistible. Live crabs are also good as bait, but the crab bait should be tied to the hook.
