What is the generally accepted upper weight limit for a mature salmon shark specimen?

Answer

550 pounds

The general consensus derived from scientific observation and fishery data establishes that a fully mature salmon shark typically reaches a maximum weight of up to 550 pounds. This figure is associated with the commonly cited maximum length of around 10 feet for mature individuals in the prime feeding grounds of the North Pacific. While theoretical scaling calculations suggest that a larger 12-foot specimen could weigh significantly more, potentially approaching 950 pounds due to volume increases, the 550-pound mark remains the figure used as the consensus upper weight limit for standard, robust adults. Real-world encounters, such as seeing one being filleted that weighed only 'a couple hundred pounds,' often reflect sub-maximal weights, reinforcing the 550-pound estimate as the expected high-end mature weight.
