The tiger rockfish Sebastes nigrocinctus is a member of a marine fishes species flock with an estimated 102 species native to the west coast of North America. Rockfishes of the genus Sebastes support important commercial and recreational fisheries on the west coast of North America and are the dominant assemblage on most cold temperate reefs. These live-bearers have a low intrinsic rate of population increase and highly sporadic recruitment, releasing large numbers of pelagic larvae into a variable coastal environment. Their slow growth rates render them vulnerable to overfishing. Uncertainty in the success of any particular year class has favored an evolutionary strategy whereby some species of the Sebastes genus have extremely long lifespans and do not show signs of aging (negligible senescence), while others demonstrate typical aging patterns and have short lifespans. S. nigrocinctus has a maximum lifespan of at least 116 years, but it is closely related to S. rubvrivinctus, which has a maximum age of only 18 years. Less...
