Its about management ! Each to his/her on liking. From my perspective its called Supplemental Feeding. We don't do aquaculture but others do. Who am I to tell them they are wrong. A good discussion though. It really does "all depend" on the situation on the ground/pond and ones goals. I will say each of us needs to understand all the +s and -s and make up their own mind.
Absolutely and I didn't want to imply aquaculture or my way is the right way or whatever. I just think it's easy to get caught up in the feeding and before you know you've got a monkey on your back.
