Made in the Shade

摘要

Last summer employees at the Dworshak National Fish Hatchery in Idaho undertook an experiment to test the effectiveness of shade cloth on fish held in raceways at the facility.During the summer it can get upwards of 43°C (110°F) at Dworshak. And while the fish remain comfortable in their 7.5°C (45°F) water, the staff tends to wither in the heat. Thus, the first benefit was that it was much more comfortable for staff ' working under the shade cloth - it felt much cooler. The shade cloth also provided UV protection for the employees.
