Abstract
The fisheries of Lake Victoria have always
been dynamic and the relevant authorities have continually tried
to manage them. During the second haIf of the last century numerous
changes took place and fisheries managers had to cope with influences
other than exploitation, including species introductions, invasive
weeds, lake level rise, changes in water quality and illegal fishing
practices. These have influenced the way the fisheries have been
managed.
In the 1920s, measures existed to manage the fisheries
of Lake Victoria. In those days, a minimum net mesh size of one
inch was in place, as well as certain restrictions for trawling
and other fishing methods. Over the years, certain fishing gears
and methods have been banned; some bans were lifted and then reimposed;
minimum mesh sizes have shifted as a result of changing species
compositions and changing needs to protect components of the stock
More recently, the fishery has been subjected to a series of bans
on export to the European Union because of outbreaks of cholera
and fish poisoning practices.
This article presents an overview of fisheries management
on Lake Victoria, the successes and failures, impacts of fish exploitation
and invasive weeds on species diversity, results of a major research
project on the lake to assess the status of the fisheries, and the
way forward.
