In many countries, especially in Bangladesh they are found in canals, beels, haors, baors and ponds. In addition, a predominately-male tilapia population reduces the likelihood of spawning, which can result in plant roots being eaten in aquaponic raft systems and wasted economic resources in aquaculture ponds.
