To develop the salmon run in the BC Hydro Salmon Stream Project in Stanley Park, eggs will be taken from Indian River chum, Indian River pink, and Capilano River coho. The BC Hydro Salmon Stream Project in Stanley Park is made up of two sections, a recirculating freshwater portion that runs from the Children's Zoo to a logjam just above the Alcan Salmon Pool Display, and a salt water portion that consists of the Alcan Salmon Pool Display and a series of stream pools that run to Coal Harbour. Salmon are anadramous, meaning they hatch in fresh water, migrate to the sea, and return to fresh water again to spawn. Most Pacific salmon are semelparous, meaning that they die after spawning. Cutthroat and steelhead are iteroparous, meaning that they may live after spawning and will return to spawn again if they survive the trip.
Pink salmon are the smallest and most abundant species.
They hardly spend any time in fresh water before travelling to the ocean, and spawn in the lower stretches of rivers when they return to fresh water. Coho are also called silver salmon. Coho spend 1-2 years in fresh water before travelling to the ocean, and spawn in small tributaries upon their return. Excessive fishing and habitat loss has caused a serious decline in the number of wild Fraser River coho. Chum are also called dog salmon.
