PeskAAS

PeskAAS provides automated monitoring and analytics for small-scale fisheries to quantify catch, effort, and spatial-temporal patterns.

Key Features:

• Component-Based Integration: Modular design integrates vessel tracking data and catch records for combined analyses.
• Spatial and Temporal Filtering: Filters fishing productivity by fishing methods and habitats across time and space.
• FishBase Length–Weight Parameters: Incorporates species-specific length-weight parameters from FishBase to convert length data to biomass estimates.
• Automated Analytics: Produces metrics for fishing effort, catch rates, economic efficiency, and geographic patterns.
• Implementation in Shiny R: Built using the Shiny R package for interactive analytical workflows.
• Support for Sparse Data: Designed to operate with limited and sparse small-scale fisheries data.

Scientific Applications:

• Standardized monitoring: Enables systematic and standardized data collection and aggregation for small-scale fisheries.
• Catch and effort estimation: Quantifies catch rates and fishing effort for assessment of fisheries productivity.
• Biomass estimation: Uses FishBase length-weight parameters to estimate population biomass from length measurements.
• Spatio-temporal analysis: Identifies geographic preferences and temporal trends in fishing activity and habitat use.
• Fisheries management support: Provides evidence for management decisions, conservation planning, and livelihood investment prioritization.

Methodology:

Implemented in R using the Shiny R package, integrating vessel-tracking data and catch records, applying spatial and temporal filtering, incorporating species-specific length-weight parameters from FishBase, and automating analytics.
