FEISTY Settings

FEISTY Settings#

This page provide a description of the settings used to configure the FEISTY model.

loffline

Run feisty in offline mode (cap fish ingestion of zooplankton using mortality term).

model_settings

This section defines aspects of the model structure, including the size classes and names of the model functional types.

size_class_bounds

Specify the names and bounds for the model size classes [grams].

Example:

size_class_bounds:
  small: [0.001, 0.5]
  medium: [0.5, 250.]
  large: [250., 125000.]
functional_type_keys

Specify the list of functional types included in the model. (Zooplankton are listed here, but are really a forcing, not a prognostic component.)

pelagic_demersal_coupling_type_keys

List the functional types that engage in pelagic-demersal coupling (if enabled in fish structure below.)

zooplankton_functional_type_keys

Specify the “zooplankton” functional types.

pelagic_functional_type_keys

Specify the functional types that inhabit the pelagic zone.

demersal_functional_type_keys

Specify the “demersal” functional types.

pelagic_demersal_coupling_apply_pref_type_keys

When computing pelagic-demersal coupling, apply prey preference-weighting to prey biomass sums.

benthic_pelagic_depth_cutoff

Benthic-pelagic coupling cutoff [meters].

zooplankton

Define the zooplankton groups used to force FEISTY. List of dictionaries with fields including:

  • name

fish

Define the fish that are simulated by FEISTY. List of dictionaries specify fish parameters.

name: The name of the fish.
size_class: The size class (must be in size_class_bounds above).
functional_type: The functional type (must be in functional_type_keys above).
t_frac_pelagic_static:
pelagic_demersal_coupling: Does this group do pelagic-demersal coupling (boolean).
harvest_selectivity: Proportion of biomass subject to fishing rate (fraction).
energy_frac_somatic_growth: Fraction of available energy routed to growth (fraction).

Example:

- name: Sf
  size_class: small
  functional_type: forage
  t_frac_pelagic_static: 1.
  pelagic_demersal_coupling: false
  harvest_selectivity: 0.
  energy_frac_somatic_growth: 1.
benthic_prey

Define the benthic prey simulated by FEISTY.

food_web

Build a food web of predator-prey relationships as a list. Here is an example entry:

- predator: Sf
  prey: Zoo
  preference: 1.
reproduction_routing

Specify how growth and reproduction is routed among model constituents.

fishing

Parameterize fishing.

fishing_rate_per_year

Biomass harvest by fishing.
