Exploration of fishing scenarios

Created: 2014-09-26 11:24:50

This workflow must run after the workflow: Resident killer whale-chinook salmon interactions. The interaction workflows generates a PostWorkspace file, this is a zip file and it is an R Workspace that transfers values from the Resident killer whale-chinook salmon interactions (main) workflow to the Exploration of fishing scenario (post-processing) workflow.

This workflow merges statistical inference derived from linkages between RKW vital rates (survival probability and fecundity rates) and chinook salmon abundance with demographic perturbation analysis and population viability analysis to address some of the pressing questions that have recently engaged the efforts of scientists and managers interested in: (1) the role of chinook salmon abundance in the population dynamics of RKW; and (2) how RKW population viability is expected to respond to changes in chinook mortality owing to harvest.

This workflow can be used to analyze interactions between chinook salmon abundance from specific stock aggregates and killer whale vital rates, the effect of these interactions on killer whale population growth, and the exploration of Chinook salmon fishing scenarios on killer whale population growth and short term projections of population size. See necessary input data.

To run this workflow in Taverna Workbench Biodiversity 2.5 requires an Rserve installation with the popbio, lattice, betareg, Formula and R.utils packages installed.

This workflow has been created by the Biodiversity Virtual e-Laboratory (BioVeL http://www.biovel.eu/) project and Fisheries and Oceans of Canada, BC, Canada. (http://www.pac.dfo-mpo.gc.ca/index-eng.html). BioVeL is funded by the EU’s Seventh Framework Program, grant no. 283359.
