“What the Fish?!” short sleeve t-Shirt
These short-sleeve “What the Fish?!” shirts will be sure to turn heads, whether you’re out collecting water samples, doing fieldwork, or in the office! These shirts are made from USA-grown sourced sustainable cotton and meets the standards set by the Fair Labor Association. Organic cotton is grown using methods that promote a more balanced ecosystem having a positive impact on the local environment and the people involved in its farming. Organic production systems support soil health, reduce the use of harmful pesticides and fertilizers, and typically uses less water.
We all have our reasons for wanting to test water quality and understand when water is healthy. For many people, understanding if the water is healthy enough to support some of their favourite fish is very important. In 2021, we decided to ask our community which freshwater fish they were most passionate about!
