Trophic Modelling for Ecosystem Based Management of Fisheries in
Reservoirs
Background:
Reservoirs ecosystems are dynamic, undergoing both natural and anthropogenic change
that can impact ecosystem process on a continual basis. These water bodies are complex
system that exhibit a range of ecological interactions. A reservoir ecosystem contains
detritus, hundreds of kind of organisms including bacteria, phytoplankton, zooplankton,
fishes, reptiles, birds etc. All these components connected in a complex food web by
evolving interactions. Hence, practical and sound management through eco system
approach is required for sustainable and efficient use of reservoirs. This involves a deep
understanding of the ecology of the system and therefore should begin with the ecosystem
properties. The overall objective of ecosystem based fisher management is to sustain
healthy aquatic ecosystem and the fisheries they support. Effective management can be
achieved through the application of mass balance trophic modelling. Mass balance models
constitute a simple approach to represent the complexity of an ecosystem and they involve
an ecological of trophic interactions between all the functional groups of the ecosystem.
Such scientific tools will provide valuable information on the health of reservoir habitats. As
well as the capacity to support biological production and sustainable development. The
training programme will provide hands on experience on the usage of ecopath software.
