Description

A table.

Usage

1

Format

Data frame with containing eight columns:

benthis_met Benthis metier used to define bottom fishing pressure
av_kw average kilowatt hours
av_loa average vessel length
av_fspeed average fishing speed
subsurface_prop proportion of the gear that fishes below 2cm
gearWidth width of the fishing gear in km
FirstFactor first parameter in the equations used to calculate abraision
SecondFactor second parameter in the equations used to calculate abraision

Details

Fill in values for variables such as average kilowatt hours and gear width for benthis gear categories. These are applied if there is no information on these quantities in the dataset being analysed.
