Question was
Are tilapia like carp, in the situation where there is little remaining food in the water column
I am not sure what is meant by little remaining food in the water column. I think TP manure creates more phytoplankton that results in more zooplankton. I have never did a study of how the zooplankton community changes with the activities of TP. It would be a very interesting small research study if I had more time. Just as a note - the zooplankton species composition changes weekly and monthly as the water temp, day length and phytoplankton composition changes. As the phytoplankton changes so goes the zooplankton populations. Both are very dynamic. Nutrient concentrations and water temperatures are big influencers.
