Spring salmon are a very important fish in the Stó:lō culture, being the focus of most of the fishing and drying methods that provided the largest and most valuable salmon storage reserves for the coming year. They are also the focus of the first-salmon ceremony. Spring salmon can reach an enormous 59 kilograms and a length of 147 centimetres. They have a blue-green dorsal area and head, with silver sides and a white ventral area. Their life cycle consists of one to 18 months in fresh water as a fry, a maximum of 190 days in the brackish water of the estuaries, and finally one to eight years at sea before returning to spawn.
Dip netting in the Fraser Canyon has developed into a series of special techniques which are used to catch salmon. Spring salmon is one of two salmon types which have methods designated specifically for the fish type.
