EcoTroph (ET): a trophic level based software for assessing the impacts of fishing on aquatic ecosystems. Gascuel, Didier; Tremblay-Boyer, Laura; Pauly, D. (Daniel)
Abstract
Director’s Foreword. Abstract. Introduction. PART I – The trophic level based model: theoretical approach. 1. Building the model: principles, assumptions and equations. 1.1. Origin of the model. 1.2. EcoTroph: general principles. 1.3. EcoTroph: biomass and flow equations. 1.4. EcoTroph and Ecopath: first comparison. 1.5. Flow kinetic equation. 1.6. Top-down control and biomass input control. 1.7. Catch equation and accessibility. 1.8. From steady-state to time- dynamic modelling. 2. Learning from the model: some generic rules of the ecosystem functioning. 2.1. Simulation of a virtual ecosystem: method. 2.2. Impact of transfer efficiency and flow kinetics on unexploited biomass. 2.3. Impact of fishing on biomass. 2.4. Catch simulations. 2.5. Dynamic model: impact of fishing on ecosystem stability. 2.6. Concluding remarks on the theoretical approach. 3. The Catch Trophic Spectrum Analysis (CTSA). 3.1. From EcoTroph to the CTSA. 3.2. Testing the method on simulated data. 3.3. Application to real case studies. 4. Conclusion: the trophic level based approach. PART II - ECOTROPH: A new tool in the EwE family. 1. General information. 1.1. Structure of the EcoTroph routines:. 1.2. Installation of the plug-in. 1.3. Additional information. 2. ET-Transpose: looking at an Ecopath model using EcoTroph. 2.1.
