The trophic ecology of the demersal fish community of lake Malawi / Niassa,Central Africa

Objective

The main objectives are defined as follows :

* To formulate trophic models that will quantify energy flows through the demersal fish community and the food web that supports it in order to understand the primary components of the food web and to detect the main ecological effects of disturbance, such as increased fishing activity, on it.
* To determine the existing fishing pressure on the demersal fish community through analysis of collected statistics in Malawi and Tanzania and to evaluate the accuracy of those statistics through calibration studies.
* To identify and produce guides for the main species of benthic invertebrates.
Expected Outcome

The project should provide information to assist in the sustainable management of fish stocks and provide recommendations for an integrated approach to the collection of fishery statistics throughout the lake. It should advance considerably the knowledge of fish and invertebrate taxonomy and provide a quantified description of food web dynamics affecting the demersal fish community. This will assist in the lake-wide management of the lake's ecosystem and strengthen the understanding of both biodiversity conservation and fisheries.
The key activities involve :

* The taxonomic description of the main fish and invertebrates relevant to the demersal fish community.
* The estimation of density, standing biomass, growth and production rates of the main components of the food web at different depths.
* The description of diet and quantification of feeding rates of the main species of demersal fish.
* The determination of catch efficiencies and selectivities of different techniques used to exploit the demersal fish community.
* The estimation of fishing and natural mortalities of the main demersal fish species.
* The estimation of the spatial distribution of fishing effort throughout the lake.
