Fish can fight malaria mosquitoes

Kenyan researchers have hailed a humble fish as the latest weapon in the
battle to curb the spread of malaria.
Nile tilapia, a fish more usually seen on Kenyan dinner tables, was
introduced to several abandoned fishponds in the west of the country.
By consuming mosquito larvae it managed to reduce numbers of two of the main
malarial mosquitoes by more than 94%.
The BMC Public Health study noted the fish could prove critical as
mosquitoes are becoming resistant to pesticides.
Nile tilapia's taste for mosquitoes has been known since 1917 but this is
the first time field data has been published detailing their use in mosquito
control, the researchers from the International Centre of Insect Physiology
and Ecology said.
Every 30 seconds
Malaria, spread by the single-celled parasite Plasmodium, is endemic in
parts of Asia, Africa, and central and south America.
This method may well work in a defined area of water, but mosquitoes spread
in all sorts of places - including small pools in the mud and puddles -
where you obviously can't introduce fish

WHO
The organism is passed to humans through the bite of a mosquito. Each year
it makes 300 million people ill and causes a million deaths worldwide.
Some 90% of cases are in sub-Saharan Africa, where a child dies of malaria
every 30 seconds.
The authors suggested that for Kenyans, the fish could prove a win-win
investment. In addition to limiting mosquito populations they could also be
used for food, and even generate income, too.
Joanne Greenfield, malaria advisor for the World Health Organization in
Kenya, was more circumspect, while describing the findings as "positive".
"This method may well work in a defined area of water, but mosquitoes spread
in all sorts of places - including small pools in the mud and puddles -
where you obviously can't introduce fish," she said. "It just wouldn't work
for many areas."
But she added: "We recommend a spectrum of methods to combat malaria, and
this could certainly be a useful tool."
