Frame, stainless steel mesh. Width 16 cm, length 18.5 cm, depth 14 cm, weight 80g. Epoxy bond used. This net is for catching baby eels (shirasu-unagi) in the upper and middle layers (about 30 cm below the water surface) without letting them escape. By using a stainless steel mesh, it has a certain weight and instantly reaches the middle layer (about 30 cm below the water surface). It can hold over 100 baby eels, reducing the number of times you need to put them in a bucket, allowing you to spend more time catching them and catch more than others. Please give it a try.
