CATDOLL : CATDOLL: Please ask someone who knows the business to see which category this sea fishing red worm belongs to among the sandworms

Please tell me which type of sandworm this sea fishing red worm belongs to

These seem to be more than one type. The red worms you are talking about are probably a species of Marphysa, belonging to the phylum Annelida, class Polychaeta, family Eunicidae. The red ones are the red gill filaments on the tubercles on both sides, see the picture below

Can anyone tell me where are the domestic bloodworm sales/purchase markets? Where are the main sales locations? How much is one pound? Thank you

Aquaculture areas, coastal special fish eel farming, and inland special fish yellow eel farming (Hubei Xiantao). Red worms are raised around the farming areas and sold in the farming areas. The price is uncertain and the profit is huge. Wholesale sales are basically monopolized by the local area.

How much does one kilogram cost where you live?
