X: Example fishery independent survey data
In marindicators: Marine Ecosystem and Fishing Pressure Indicators

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

This example data is a dataframe with 2003 rows and 5 variables:

YEAR: Year the observation was recorded
ID: Area where the observation was recorded
SPECIES: Numeric code indicating the species sampled
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 fishery independent data (among other arguments): Heip's Evenness Index, Hill's N1, Hill's N2, Kempton's Q, Margalef's Species Richness, Pielou's Species Evenness, Shannon's Diversity Index, Biomass ratio(s), Abundance/Biomass of Species Groups, Large Species Indicator, Mean Trophic Level of the Community, CV of Biomass, Mean Maximum Lifespan, Mean Maximum Length, and Fishing Pressure.

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