Malaria is a disastrous plague, with millions of affected victims every year and thousands of dead every day. Africa is mostly hurt, and particularly children suffer and die from this disease. First of all, the million fold individual suffering and dying is shocking.
Besides this, however, the adverse economic impact of malaria is enormous, too.
In the past years, the World Health Organization has suggested the use of DDT and other insecticides for indoor-spraying and preparation of mosquito bed nets. From the toxicological and ecotoxicological point of view, this strategy is critical and questionable.
Bio-environmental strategies, however, are at hand, which are powerful, yet cost-effective. Therefore, it appears reasonable to increase efforts to use non-chemical methods for malaria prevention and control.
A very promising approach to control malaria has been made in various regions of the world by use of fish, which feed on mosquito larvae. Mosquitoes are vectors of the disease, and their number can be significantly decreased by larvae feeding fish. Considerable fish species are Gambusia affinis and Nothobranchius guentheri, but also others.
