init_fleet
sets up the parameters and results data frame
to record the catches from the simulation.

)
sim_init |
is the output (a list) from the |
VPT |
is a named vector of numerics detailing the value-per-tonne for catches from each of the species (same for all fleets) |
Qs |
is a list (an element for each fleet) with each element containing a named vector with the catchability parameters for each species the vessels in the fleet |
fuelC |
is the fuel cost per unit of distance moved in euro |
step_params |
is a list (an element for each fleet) with each element
containing a named vector with the step parameters used in
|
past_knowledge |
is a Boolean (TRUE / FALSE) whether past knowledge should determine fishing location (only after the first year) |
past_year_month |
is a Boolean (TRUE / FALSE) that indicates whether the same month in previous years should be included in the past knowledge decision |
past_trip |
is a Boolean (TRUE / FALSE) that indicates whether the past trip undertaken should be included in the past knowledge decision |
knowledge_threshold |
is a numeric (0 - 1) detailing the threshold at which a fishing tow should be considered "good" and included in the selection of possible choices of starting fishing locations in future tows. |
is a list with three elements containing i) the fleet parameters, a named list fleet_params, ii) the fleet catches, catches_list, which is a list of a list. For thecatches_list the first element denotes the fleet number, the second element is the vessel number with a dataframe for recording the vessels catches. Finally, iii) is the spatial catches for the fleets, which is a list (fleet) containing a list (vessels) containing a list (population) - which is to be passed to the delay difference model.
