World Fisheries Day, celebrated on November 21, is dedicated to highlighting the critical importance of healthy ocean ecosystems and to ensure sustainable stocks of fisheries in the world. Pressure to find ecologically sustainable strategies for harvesting food from the sea is getting ever stronger, especially in the face of changing climate. However, the question is complex because the harvestable species live in a complex food web where everything is directly or indirectly connected to everything else. Models for carrying out scenario analyses on the impact of fisheries management options on food webs are usually the preserve of trained experts.

In this blog post, Michael Heath of the University of Strathclyde guides us through how using a new marine modelling package and online app, published in their recent Methods in Ecology and Evolution paper ‘StrathE2E2: An R package for modelling the dynamics of marine food webs and fisheries.’, makes these analyses easily accessible to anyone with just basic website skills.
