Woody,
I'm sure Ewest will respond, but I have heard this same story many times. I don't pretend to know the answers but have some thoughts/questions.
It's my understanding that a fert. regiment is used to maximize production of a pond. IE: A good bloom is the basis of a productive pond in that it feeds the small stuff that feed the bigger stuff (the phyto. feeds the zoo, feeds the fry) & so on.
If one is not necessarily trying to maximize production IE: 600# per acre, why maintain a maximum bloom?
Would not a 24" to 36" bloom serve to benefit the bottom of the food chain when only say 2/3 of max potential production with less likelihood of causing a DO crash? Esp. when feeding?
Also I'm curious about the statement of Tilapia not competing with BG. Don't they have a negative effect on the basis of the food chain & therefore the same negative effect on the BG fry?
Ewest, maybe you or Greg could address my ignorant questions?
