X_length: Example length-based fishery independent survey data
In marindicators: Marine Ecosystem and Fishing Pressure Indicators

A dataframe of example length-based fishery independent survey data for two areas (AREA1 and AREA2) from 2014 - 2019.

X_length

This example data is a dataframe with 14378 rows and 6 variables:

YEAR: Year the observation was recorded
ID: Area where the observation was recorded
SPECIES: Numeric code indicating the species sampled
LENGTH: Length class of sample species, in cm
ABUNDANCE: Abundance of the species sampled, stratified and corrected for catchability
BIOMASS: Biomass of the sampled species, stratified and corrected for catchability

Indicators calculated using length-based fishery independent survey data (among other arguments): Community Condition, Large Fish Indicator, Mean Length.

This is made-up example data modified from Fisheries and Oceans Canada summer research vessel trawl survey for the Scotian Shelf Bioregion.
