Data from: Species' ecological functionality alters the outcome of fish stocking success predicted by a food-web model
Fish stocking is used worldwide in conservation and management but its effects on food-web dynamics and ecosystem stability are poorly known. To better understand these effects and predict the outcomes of stocking, we used an empirically validated network model of a well-studied lake ecosystem. We simulate two stocking scenarios with two native fish species valuable for fishing. In the first scenario, we stock planktivorous fish (whitefish) larvae in the ecosystem. This leads to 1% increase in adult whitefish biomasses and decreases the biomasses of the top predator (perch). In the second scenario, we also stock perch larvae in the ecosystem. This decreases the planktivorous whitefish and the oldest top predator age class biomasses, and destabilizes the ecosystem. Our results demonstrate that the effects of stocking depend on the species' position in the food web and thus cannot be assessed without considering interacting species. We further show that stocking can lead to undesired outcomes from both management and conservation perspectives. The gains of stocking can remain minor and have adverse effects on the entire ecosystem.

Global Fishing Index: a global dataset of relative biomass of fish stocks in national waters
<p>The Global Fishing Index (GFI) is an independent global assessment of the state of marine fisheries, measuring country-level progress towards achieving the United Nation’s Sustainable Development Goal Target 14.4. This stock-level dataset provides estimates of relative biomass (current biomass relative to historic ‘unfished’ biomass) and reconstructed catch for 1,438 unique marine fish stocks, spanning the national waters of 142 maritime countries. The dataset includes biomass estimates for 2018 from stock assessments published by national and regional authorities, as well as estimates made using data-limited models (the Bayesian Schaefer Model and CMSY++) and publicly available data. To ensure the integrity and reliability of stock-level data included in the GFI 2021 sustainability dataset, the data were subject to a comprehensive and rigourous quality assurance process, including both internal and external expert review. This global dataset advances scientific knowledge on the state of fisheries globally, serves as a benchmark to track progress and inform future studies, and supports improved research and management to advance global efforts towards fisheries sustainability.</p>
