Catch Advice for Fisheries Managed by Harvest Slot Limits
Description
Catch advice for data-limited vertebrate and invertebrate
fisheries managed by harvest slot limits using the SlotLim harvest
control rule. The package accompanies the manuscript "SlotLim: catch advice
for data-limited vertebrate and invertebrate fisheries managed by harvest
slot limits" (Pritchard et al., in prep). Minimum data requirements: at
least two consecutive years of catch data, length–frequency distributions,
and biomass or abundance indices (all from fishery-dependent sources);
species-specific growth rate parameters (either von Bertalanffy, Gompertz,
or Schnute); and either the natural mortality rate ('M') or the maximum
observed age ('tmax'), from which M is estimated. The following functions
have optional plotting capabilities that require 'ggplot2' installed:
prop_target(), TBA(), SAM(), catch_advice(), catch_adjust(), and
slotlim_once().
