Dataset. Hou et al. A fish tale A century of museum specimens reveal increasing microplastic concentrations in freshwater fish.

Summary

This is a data repository entry accompanying a century-scale museum specimen study that tracked increasing microplastic concentrations in freshwater fish over time. The dataset supports a published research article examining fish collected over 100 years of natural history collections. The data itself enables analysis of how plastic contamination of freshwater fish has changed since plastic production began.
