The introduction of tilapia to irrigation reservoirs in Israel improved the efficiency of water usage and reduced the cost of water needed for tilapia culture. Although requiring considerable investment, many dual-use reservoirs were constructed and equipped for efficient harvesting. In a study, the authors found that increasing overall tilapia yields through higher stocking density did not guarantee profitability. On the contrary, lower total yields consisting of larger tilapia resulted in higher returns per kilogram of fish.
