How long do they live? Canary rockfish can at least live up to 84 years old [1, 2] that we know of.

Where are they found? The range of Canary rockfish is from the western Gulf of Alaska down to northern California. They can be found from 260 feet all the way to almost 2,800 feet deep [3].

What do they eat? Canary rockfish enjoy eating small things, such as krill, fish eggs and larvae [3].

What do they look like? This species can look pale orange, yellow, to darker yellow in color and it has 3 bright stripes across its head.  The maximum length and weight that has been recorded for the Canary rockfish is around 2.5 feet and 9 pounds [4]. See figures 1 and 2.

How do they reproduce? They are viviparous and release live young into the water. Canary rockfish reach sexual maturity between 9  to 13 years of age [3].

How do scientists know how old they are? Otolith annuli age estimations and bomb radiocarbon verification [1, 2].

So what are we lacking? It’s late, so I feel the need to bullet point.

  • There is no nuclear genome or mitochondrial genome information on the NCBI website, but there has to be mitochondrial genome information out there because we know this is a separate species from other rockfish.
  • There’s a bit of debate about when this species reaches sexual maturity.
  • I could not find any information regarding reproductive senescence.
  • And worse: this fish has not been evaluated by the IUCN, but they have experienced great declines since the 1960s due to overfishing [3].
