I don't know who you are but you had posted some great video about winter flounder. I can't understand Japanese, but could you recommend what would be a good bait to catch winter flounder(small mouth)? From where I live (USA), it seem like they won't eat anything else other than seaworm, and seaworm is extremely costly in here. Just 2 worms = $1.25. Please tell what is a good bait to catch these species? Can you catch them on tiny lure? I had tried lure but again, they won't hit.
Sea worms are also expensive in Japan. So I cut the squid into strips and colored it green to catch the flounder. Now you can trick the fish into catching them
