A dataframe of example fishery independent survey data for two areas (AREA1 and AREA2) from 2014 - 2019.
XThis example data is a dataframe with 2003 rows and 5 variables:
Year the observation was recorded
Area where the observation was recorded
Numeric code indicating the species sampled
Abundance of the species sampled, stratified and corrected for catchability
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.
