FWIW, there are no pure strain T-Moz out there....all are hybridized now. I seriously question and doubt the weight gain data, or view it as very misleading, at best. Lost growth in fish, including Tilapia, is forever lost and can't be reclaimed. A fish with a high Wr, and in an environment of unlimited food supply will always outpace a larger fish of low Wr, in growth percentage relative to length. A larger fish, with a larger mouth can simply eat more volume than a smaller fish, so the larger fish would always gain more total weight, yet will yield a lower percentage of meat....Like I say, the data, at best, is misleading. Also, it is not uncommon for 1/4-12 pound stockers to gain 2+ pounds in a single growing season in a pond. Females only gain less because they eat less while brooding eggs/fry, and energy diverted into growing eggs. I also don't know where you got your info claiming T-Moz are more fecund than a T-Aurea. Average egg production is the same. The Blue (T-Aurea) becomes sexually mature about 2 weeks later than the 12 weeks of T-Moz, and T-Nilotica much later. The T-Aurea however, has a lower temperature range for laying eggs than the T-Moz, so is actually the most fecund of species stocked in sportfish ponds, and early off spring will also be laying eggs, longer....Info and conclusions on Tilapia matters a lot whether the fish are in a sportfish, or food production setting, as management is almost the exact opposite for each setting....ie what is great for food production, is horrible when used in a sportfish pond
