Description Usage Arguments Value Using the Rochet et al data set See Also Examples
Runs the LeMANS model with the bundled data.
Bundled data conist of the 22 species used in the Rochet et al (2011) paper to represent Georges Bank. See rochet_GB_species
.
The code was adapted directly from MATLAB code used in the Hall et al (2006) and Rochet et al (2011) papers.

Ffull |
Fishing mortaliy rate for a fully recruited fish |
nYrs |
Number of years to simulate. |
modelSetup |
list of parameters required for model (See |
parameterValues |
matrix of species specific parameters (See |
initialValues |
matrix of initial abundance estimates (See |
foodweb |
predator prey food web (See |
species |
matrix of species names and guild membership (See |
A list containing:
N |
3D array of abundance (numbers of animals). nsizeClass x nSpecies x nTimeSteps |
M1 |
Matrix of M1 mortality ("natural"). nsizeClass x nSpecies |
M2 |
3D array M2 mortality (predation). nsizeClass x nSpecies x nTimeSteps |
F |
3D array M2 mortality (predation). nsizeClass x nSpecies x nTimeSteps |
catch |
3D array of catch (numbers of animals). nsizeClass x nSpecies x nTimeSteps |
SSB |
Matrix of spawning stock biomass (SSB). nSpecies x nYears |
recruits |
Matrix of recruits (numbers of animals). nSpecies x nYears |
suitability |
3D array of prey suitability by predator. nsizeClass x nSpecies x (num Pred.size class combinations). See |
sizePreference |
3D array of prey preference by predator. nsizeClass x nSpecies x (num Pred.size class combinations). See |
ration |
Matrix. Amount consumed to account for growth. See |
growthEfficiency |
Matrix of growth efficiencies. See |
growthProportions |
Matrix of proportions. Proportion of individuals that leave each size class in each time step. See |
maturityProportions |
Matrix of maturity proportions. See |
modelTimeStep |
scalar representing the fraction of a year each time step represents. See |
The number of size classes and the width of the size class was decided upon a priori.
This decision was based on the maximum L_inf among all species. max(Linf) = 148 cm
The rochet_GB_initialValues
should be set up to represent the number of size classes and width.
The unit of output for Rochet et al data:
catch, N: number of individuals
M1, M2, eF: rates
recruits and SSB: were scaled to common recruit and spawning stock size units (individuals × 10^6 and tonnes × 10^3, respectively)
