This publication describes work carried out on Lake
Malawi. Daily, remotely sensed maps of lake surface
temperature were compared with information collected in
situ. Fisheries scientists found strong agreement between the
two methods and were successfully able to monitor changes
in the structure of local fish populations following changes
in lake water temperatures. This booklet will not only be of
interest to those concerned with the study and management
of African fisheries, but also to those interested in expanding
monitoring of environmental changes using remote sensing.
