Chum salmon average between 7 and 18 lbs (3-8 kg). Capable of reaching 30 lbs (14 kg), the chum is the second largest Pacific salmon, on average. Chum are also known as dog salmon, which may come from the massive, dog-like teeth males develop when spawning.
Like the king salmon, chum may spend a variable number of years in the ocean before returning to freshwater to breed. Chum were the favored salmon of fur farmers to feed their animals due to their size and abundance.
