This is a really smart invention Iniha, the simple act of playing the fish some music would help in the large effort to prevent over-fishing! I like the idea of the radio only being targeted at fish, so it does a specific job and is channelled to communicate only to sea life, this is a very unique feature. Your drawing is so wonderful in that you have expertly drawn so many different types of fish and illustrated the radio beautifully! This would definitely improve the condition of our oceans and help preserve sea life! Great thinking Iniha, keep it up!
