Yelloweye rockfish
The yelloweye rockfish (''Sebastes ruberrimus'') is a rockfish of the genus ''Sebastes'', and one of the biggest members of the genus. Its name derives from its coloration. It is also locally known as "red snapper",〔〔 not to be confused with the warm-water species ''Lutjanus campechanus'' that formally carries the name red snapper. The yelloweye is one of the world's longest-lived fish species, and is cited to live to a maximum of 114 to 120 years of age. As they grow older, they change in color, from reddish in youth, to bright orange in adulthood, to pale yellow in old age. Yelloweye live in rocky areas and feed on small fish and other rockfish. They reside in the East Pacific and range from Baja California to Prince William Sound in Alaska.
Yelloweye rockfish are prized for their meat, and were declared overfished in 2002, at which time a survey determined that their population, which had been in decline since the 1980s, was just 7-13% of numbers before commercial fishing of the species began. Because of the slow reproductive age of the species, recovery of the species is difficult, and liable to last decades, even with the harshest restrictions; Washington state, for example, maintains a quota of under 1000 individuals per year. It is currently under consideration for listing under Threatened or Endangered status.
==Characteristics==
The yelloweye rockfish is colored red on its back, orange to yellow on the sides, and black on the fin tips. Its young are typically under in length, and differ from the adults in that they have two reddish-white stripes along their belly,〔 and are often red. Because of the distinct difference in coloration between juveniles and adults, they were considered separate species for a long time.〔 Its head spines are exceptionally strong. They grow to a maximum length of and are typically found in the range, although specimen have been reported up to a maximum depth of .〔(【引用サイトリンク】title=Yelloweye rockfish )〕
Yelloweye rockfish live to be extremely old, even for their unusually long-lived genus. They average 114〔 to 120〔 years of age; the oldest ones reach as much as 147 years. They fade from bright orange to a paler yellow as they grow in age. They are exceptionally slow developing as well, not reaching maturity until they are around 20 years of age.〔
