Pro, I'm sorry, the correct species of Tilapia for the area does indeed control algae...proven in 1000's and thousands of ponds. Tilapia utilize virtually all nutrient the consume at a rate of 1.2:1...that "excretement, is nearly devoid of nutrient. Unlike other fish waste.
Rex,
Do you have any literature i. e. studies to back this up? I'm not disagreeing with you and don't have any of my own tilapia experience but it just seems hard to swallow that their excretement is "nearly devoid of nutrient." If so why is it sold as plant fertilizer? And I understand it's more foul and prolific than other species.
