Hey guys I'm just trying to pass on this wisdom! You can actually save every part of the fish and have a use for it. I am a trout fisherman and was cleaning my fish when i noticed this one guy was leaving with his fish uncleaned. He told me that he goes out to his garden, makes a small hole, puts all the guts, head, and tail into the hole and covers it. I've tried this for the past few months and its worked great for my moms roses, veggies, etc.
Just thought I'd pass that on...
