BioIndex: Biological Indicators and Indices for MEDITS Survey Data
Supports the standardized analysis of Mediterranean
International Bottom Trawl Survey (MEDITS) data and the calculation
of biological indicators for selected species and population
components. The package provides functions to estimate abundance
and biomass indices, analyse size structure and length frequency
distributions, derive sex ratio and maturity related metrics,
explore spatial patterns, and assess temporal trends across
surveys. Developed for integration within the Regional Database
for Fisheries (RDBFIS) framework, it is intended to work on
quality checked input data and to produce reproducible outputs
that can support monitoring, comparative analyses among
Geographical Sub-Areas (GSAs) and countries, and fishery management.
