4.6 R Resources for Fisheries Analysis: Essential Tools and Packages

Essential R Resources for Fisheries Analysis 🎯

R has become a cornerstone tool in fisheries science, offering a wide range of specialized packages and resources. This tutorial will guide you through some of the most valuable R resources available for fisheries analysis, from data access to stock assessment.

Core Fisheries Resources in R

Let’s explore some essential resources that every fisheries researcher should know about:

1. FishBase Access with rfishbase (works only locally) 🐟

The rfishbase package provides programmatic access to FishBase, one of the most comprehensive databases of fish species information:

Key features of rfishbase: - Access to species taxonomy - Life history parameters - Length-weight relationships - Distribution data - Ecological information

2. The fishR Package 📊

The fishR package, documented at fishR-Core-Team, provides tools specifically designed for fisheries analysis. You can find there an incredible collection of teaching materials and packages for fisheries science.

fishR provides: - Age and growth analysis - Mortality estimation - Stock assessment tools - Data visualization functions

3. Using Mixed-Effects Models in Fisheries

The book “Using R for Modelling and Quantitative Methods in Fisheries” (URMQMF) provides excellent guidance on: - Statistical modeling - Stock assessment - Time series analysis - Survey design

Let’s look at an example of modeling catch data:

Additional Useful Resources 📚

1. Stock Assessment Packages
   • FSA (Fisheries Stock Assessment)
   • TropFishR for tropical fisheries
   • ss3sim for Stock Synthesis simulations
2. Spatial Analysis
   • sf for spatial features
   • marmap for marine maps
   • oceanmap for oceanographic data

Let’s see an example of spatial visualization:
