Application of SEAPODYM to swordfish
Estimates of climate change impacts
The Pacific-based optimal parameterization of SEAPODYM for swordfish has been used to obtain a configuration for the Indian swordfish population. Simulations are driven by 1952-2012 historical geo-referenced catch data and by the same environmental forcing (NCEP-ORCA2-PISCES).
Available catch per unit of effort (CPUE) data from the fisheries operating in the study area are used with the MLE approach to estimate fisheries catchability parameters.
