More tilapia, higher profit?
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.

Trial finds biomass harvest of cobia unaffected by stocking density in RAS
The establishment of land-based recirculating systems for cobia could expand production of the species. The authors, who demonstrated cobia are well suited for culture in tanks, conducted a study to compare the performance of cobia reared at different densities.

Animal density, pathogen load related factors in disease outbreaks
Consideration of the effect of animal density usually does not include the critically important contribution of pathogen concentration to the dynamics of disease outbreaks.
