About Species_ID
Species_ID is an analysis export variable.
It reports the species ID number for which a biomass variable has been calculated in this analysis. This is a number assigned internally by Echoview which uniquely identifies each species in an EV file.
This variable is exported only if one of the biomass variables is exported.
