Growth of an Inshore Antarctic fish, Trematomus newnesi (Nototheniidae), off Adelie Land
Dusky rockcod, Trematomus newnesi, is a widely distributed neritic circumpolar Antarctic fish species. We conducted a study on age and growth of Trematomus newnesi in coastal waters of Adélie Land in East Antarctica. A total of 289 specimens were collected in 2003, 2005, 2006 and 2009. They consiste...

They consisted of 122 females, 132 males and 35 immature specimens. Total length (TL) and total weight (W) of these fish ranged from 13.5 to 25 cm and 19.7 to 174 g respectively for females and from 12 to 20.9 cm and from 24.1 to 144.1 g for males.
