Fease-class: Class 'Fease'

Description

An object for storing information about what data are available or might be available

Slots

Name

The name of the data feasibility object

Case

The names of the data feasibility cases

Catch

Total annual catches

Index

An index of relative abundance, catch per unit effort data or of fishing mortality rate (effort)

Natural_mortality_rate

From Maximum age, Tagging data, early fishery catch composition data

Maturity_at_length

From gonadal analysis, growth and natural mortality rate estimates

Growth

Paired length and age observations, maximum length and an estimate of natural mortality rate

Length_weight_conversion

Paired weight and length observations, equivalent data from a similar species

Fleet_selectivity

Length composition of catches with growth curve and natural mortality rate, estimates from a similar fleet type targetting a similar species

Catch_at_length

Length composition of catches (length samples)

Catch_at_age

Age composition of catches (age samples)

Recruitment_index

Spawn survey, estimates from a stock assessment, VPA analysis of catch composition data

Stock_recruitment_relationship

Stock assessment, a stock assessment of a similar species

Target_catch

An agreed annual catch target, MSY proxy

Target_biomass

An agreed absolute biomass target, mean historical biomass estimate

Target_index

An agreed catch rate target

Abundance

Fishery independent survey, current fishing mortality rate from recent length composition, natural mortality rate, maturity at age, growth and stock recruitment relationship, habitat and relative density extrapolation
