Quantitative modelling of Labeobarbus species as a basis for stock assessment and management in Lake Tana Ethiopia

The populations of Labeobarbus species in Lake Tana are threatened due to intensive fishing. This modelling study will focus on the spatio-temporal dynamics of the populations based on reproduction, growth and mortality parameters determination. The outcomes will be used for determining a growth performance index of the fish species that can serve as a basis for a sustainable population control. As part of the research, also monitoring methods will be analysed and optimised, in particular the gillnet selectivity and efficiency will be determined. Moreover, the socio-economic relevance of Lake Tana fisheries will be determined based on ecosystem services analysis.
