Rougheye rockfish Add your observation in Fish Watcher. The previous record age for a caught rockfish was about 175-years-old, and that fish, at about 32.5-inches-long, was smaller than this latest catch.

Probably the longest-lived marine fish on Earth, the Rougheye rockfish certainly lives up to its Latin name— Sebastes comes from Sebastos, which is Greek for ‘magnificent’. A lot of rebaiting time can be saved by utilizing a "difficult to steal" bait.

The yelloweye rockfish is a rockfish of the genus Sebastes, and one of the biggest members of the genus.

Scientists have discovered that by counting the layers of a deceased whale’s waxlike earplugs, they can get a close estimate of the animal’s age. References Aquaculture In Alaska, scientists aged one specimen to 205 years. Maximum age is at least 205 years old. Maximum estimated age is 21 years.

2. These ratios might also be useful in disaggregating historic catches where only Rougheye Rockfish were reported. Continue the effort on the approaches in weighting length/age frequency. Age reading fish in Juneau The ADU uses the break and burn technique in which otoliths are broken in half at the center and toasted over an alcohol flame, making the bands easier to see and count. Like most rockfish of the genus Sebastes, it only grows to 38 inches in length with a maximum weight of 14 pounds, despite the astoundingly long lifespan. The oldest blue whale found using this method was determined to be around 110 years old.

However, rougheye are distinguished by 2-10 spines below their eyes and long thin gill rakers on the first gill arch. The

It is also locally known as "red snapper", not to be confused with the warm-water Atlantic species Lutjanus campechanus that formally carries the name red snapper. The Rougheye is also known as a Red Snapper and a Rock Cod. One of the longest lived fishes in the world. Some key recommendations for rougheye rockfish assessment are summarized below: !

Until recently, these were thought to be one species, and are still managed as one complex. The rougheye rockfish assessment was considered to be based on the best available data, and constitute the best available information on this species along the U.S. West Coast. That age difference has important implications for managing these species. The Rougheye can be found from the deep waters off the coast of Japan to San Diego.

Maximum age is at least 157 years old.

This species is most often confused with rougheye rockfish. Conrath found the age at maturity for rougheye was less than 20 years; for blackspotted, over 27 years. Another important finding was a marked difference in the age that rougheye and blackspotted rockfish reach reproductive maturity.

It was caught this year in the Southeast Alaska commercial fishery. Currently, the oldest yelloweye rockfish the lab has aged was 121 years old. Average lifespan is estimated at around 80 to 90 years.
