I've heard from my friend that small octopus likes any sound frequency, and someone(I think they are Japanese) use that sound frequency in catching small octopus.
But i cant find that sound frequency that small octopus likes,
If you know the frequency, please share me that.
if you dont know that, you can find that in japanese site.
Best regards
Thanks
