Calculate daily mortality and reproduction (Mid-level - Main function) — calculate_mortality

Calculates daily mortality probability and reproductive energy loss (natural mortality, fishing mortality, predation mortality, starvation, and weight-dependent survival) for a single time step.

Usage

calculate_mortality_reproduction(
  current_weight,
  temperature,
  day_of_year,
  processed_mortality_params,
  initial_weight = NULL
)

Arguments

current_weight: Current fish weight (g)
temperature: Water temperature (deg C)
day_of_year: Day of year (1-365)
processed_mortality_params: List with processed mortality parameters
initial_weight: Initial weight for relative calculations (optional)

Value

List with mortality and reproduction results

Experimental

Mortality rate modelling is an **experimental feature** under active development. This function can be called directly to compute daily mortality probability for a single time step, but **mortality rates are not yet integrated** into the main `run_fb4()` simulation loop. Full integration (automatic daily mortality application, population survival tracking, and result reporting) is planned for a future release. The API may change.

Note: **spawning energy loss** (reproductive cost) *is* already integrated into `run_fb4()` and applies automatically when `reproduction_data` is supplied to the `Bioenergetic` object.
