Norway redfish (Sebastes vivparus), looks like the bigger rosefish (Sebastes norvegius), also known as the Norway haddock, but as the local fishermen say “it is only half a rosefish”. The redfish is only half the size (35 cm), dives only half the depth (10-200 m) and only give birth to half the numbers of juveniles as the bigger rosefish.
The redfish is slightly brighter in the colour and has a dark spot over the last gill cover. It gives birth to living off springs, around 30.000 in June to August. The eggs are fertilized, matured and hatched inside the female. The kids are not fully developed when they are released but quickly grow to 20 mm. They are pelagic until they are around 6 cm. They can live for a long time, up to 30 years. It lives of shrimps, clams, bottom dwellers and small fishes.
The Redfish is rather common here in Saltstraumen, you find it in Oksebåsen, along Ørneset and Tuv where it can find some shelter from the strong current.
