## DATA DESCRIPTION Folders "m0_no-fishing", "m1_SUF", "m2_FFRc" and "m3_FFRc+mask" contain long-term outputs from the spatial population dynamic model, StrathSpace, for both mesopelagic species Benthosema glaciale and Maurolicus muelleri. Each folder corresponds to a specific model setting for fishing mortality, which are: - m0: no fishing - m1: spatially uniform fishing model (SUF) where fishing mortality is the same in any location of the spatial domain. - m2: fishing functional response type III with effort reallocation (FFRc), model where fishing activity and effort is concentrated in areas of high population density. - m3: model using both FFRc and a fishing mask which restricts the fishing activity to areas within a 460m distance from ports (FFRc+mask). These long-term models were ran from 1980 to 2098 with a spin-up period of 30 years. In each model folder and for each model run, a set of figures (including length distributions, time series, spatial distributions) is available in the "figures" subfolder. The "yield-curves" folder include key figures from outputs used in producing annual yield curves between 1980 and 2097 with a 3-year interval. ------------------------------------------------------------------------------------------------------------ The following files give details on the model's options (with default values) and define the model's spatial grid: Description of model parameters for StrathSpace: - model-opts_def.txt Mesh and mask file (including approximation of cell surface (areas in km^2) for density calculations): - model_mesh_mask.nc
