Fishing has always been a primary activity with the Stó:lō people. Salmon, including pink, coho, sockeye, spring, and chum, is the main food source for the people of the river and is central to their economy. As only a small portion of the salmon catch is cooked fresh, a majority of the salmon caught is preserved by wind-drying, salting or smoking to provide a resource that can be consumed throughout the year. Wind-dried salmon can last up to two years, and it was commonplace to trade this preserved salmon with people in other territories for resources not available in the Fraser Valley. Salmon is also intricately woven into the Stó:lō spiritual beliefs, and many of the oral narratives speak of this fish as having a very important role in the origins of the Stó:lō people and the Stó:lō way of life.
