Aa-ron Thank you for your comment! I'm not good at English and I'm sorry if the sentence I'm writing is wrong. I am writing sentences while translating with the app. This is one of the traditional Japanese fishing methods and is called hole fishing. Tie a string to an eel hook and apply an adhesive to make it sturdy. Use a short bamboo and put it in a hole to fishing eels.Feed is river fish and river shrimp. Thank you very much for your interest!
