Teleostei (teleosts) > Perciformes/Notothenioidei (Icefishes) > Nototheniidae (Cod icefishes) > Pleuragrammatinae
Etymology: Dissostichus: Greek, disso = twice, one or other + Greek, stix, stichos =line, row (Ref. 45335);  eleginoides: eleginoides deriving from the genus Eleginops for an assumed resemblance to that genus (Ref. 11892).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 8 - 10; Dorsal soft rays (total): 28 - 30; Anal spines: 0; Anal soft rays: 28 - 30; Vertebrae: 53 - 54. Lateral line scales 88-104 (upper), 61-77 (lower).

Biology     Glossary (e.g. epibenthic)

At 12-15 cm TL, semi-pelagic juveniles become demersal at 150-400 m depth (Ref. 55957). Adults migrate to deeper habitats at depths greater than 1,000 m (Ref. 55957). Utilized as food fish (Ref. 4931).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

May spawn for the first time from around 8-10 years of age (Ref. 71843).
