ARTFISH Overview - Shiny Server Module

Source: R/artfish_shiny_overview.R
artfish_shiny_overview_server.Rd

Server-side logic for the ARTFISH Overview dashboard.

The *"Total catch and effort - Statistics at country level"* module provides a high-level visualization of key output metrics derived from artfish_compute_report. It acts as a dashboard to track the overall evolution of fishing activity over time, with the ability to filter by fishing units and time range.

The module is composed of:

  • A selector panel to adjust the time range and fishing units to display

  • A set of KPIs presenting aggregated country-level metrics for the selected period

  • Seven boxed plots powered by fdishinyr::generic_chart allowing users to analyse:

    • (1) Total catch estimation

    • (2) Species composition (by quantity)

    • (3) Total nominal effort

    • (4) Number of active vessels

    • (5) Total value estimation

    • (6) Species composition (by value)

    • (7) Catch per unit effort (CPUE)
