Standard Methods for Fish Sampling in Africa

Several fishing methods have been employed in Africa for centuries largely influenced by local environmental conditions, past traditional beliefs, taboos and cultural practices. These have changed dramatically due to increased urbanization, immigration and implementation of colonial fisheries legislature, consequently leading to dominance of contemporary practices and fishing gear. In spite of this, a number of traditional fishing methods persist. Hand harvesting is one of the simplest methods and is still used by subsistence communities. In addition, a diversity of traps made from plant material derived from macrophytes. Contemporary fishing methods that employ a great deal of technology are also applied in research and commercial fisheries including hook and line, purse seine, trawl, longline & traps. This presentation will highlight some standard research methods of fish sampling in Africa and elaborate on methods of standardization of catch across samples for estimations of catch per unit effort. The presentation will also highlight participatory methods involving village-based water level recorders and fisheries data collectors. Various challenges of fishing in Africa will be highlighted including difficult terrain, insecurity and encounters with dangerous wildlife.
