StoxBioticFormat: StoxBiotic data format.

In RstoxData: Tools to Read and Manipulate Fisheries Data

Description

The StoxBiotic data format is defined by StoX as a common format to which data from different biotic sampling formats are converted, guaranteeing consistent interpretation and documentation of all its variables.

Details

The StoxBiotic format is defined according to the general sampling hierarchy of StoX which is used as a basis for both the StoxcBiotic and StoxAcoustic format. The variables of the StoxBiotic format are given by the tables below:
