"It's a bug that looks like an earthworm, but if you look closely, it has two rows of feet. It is an invertebrate marine organism with high nutritional value, which mainly grows in coastal beaches. Nereis is mainly used for fishing because of its high protein content (up to 68%). It is a high-quality bait for artificial reproduction and culture of fish, shrimp and crab. It is also called' universal bait' by fishing enthusiasts, especially suitable for hanging fish in the deep sea. "

"The skill of digging worms: quick eyes and quick hands. Pull your head when you dig, not your tail. Harmless nereis can live for at least a week. By controlling the appropriate temperature, the survival time of Nereis can generally reach 7- 10 days. As bait for deep sea fishing, it is important to be fresh. "

"Put the worm in a wooden box, pour some seawater and put it in the shade. The worm can survive for 2 or 3 days. Or: put the dug nereis into a vessel, add white wine, soak it quickly ... drain the wine, sprinkle salt according to the amount of 10: 1, stir it evenly, put it into sawdust, (for the purpose of absorbing water), put it into a plastic bag, tie it tightly, put it in a refrigerator, freeze it, and take it whenever necessary. This treatment method can keep the worms for a long time without discoloration or hardening, which is no different from fresh bait. "
