Reproduction and larval growth of Harpagifer antarcticus Nybelin (Pisces, Notothenioidei)
Antarctic Science, 1992The spiny plunder-fish, Harpagifer antarcticus, is a common shallow-water demersal species distributed along the southern limb of the Scotia Arc. A year round study was made of its reproductive biology at Signy Island, South Orkney Islands, for comparison with populations from the Antarctic Peninsula and with H. georgianus at South Georgia.

1189 fishes of 13 species from the Nototheniidae and Chaenichthyde families were studied in subantarctic waters of the Kergelenian subregion (Indian Ocean) and in waters of the Falkland Islands and South Georgia (Atlantic Ocean). 3 species of parasitic worms, 3 species of parasitic crawfish and 2 species of leeches were found. A considerable difference

The osteological development of nine species of Nototheniidae (Perciformes: Notothenioidei)
1997The osteological development of nine species of nototheniids was investigated. All the species in general are characterized by the similar sequence of appearance of bones, except for Pleuragramma antarcticum. It is shown that the latest appearing bones are as a rule reduced in more derived species of the nototheniids and/or in advanced families of the ...

Notothenioid fishes (Notothenioidei)
2009Abstract Notothenioids represent an adaptive radiation of teleost Ashes in the frigid waters of the Southern Ocean surrounding Antarctica (1). Of the 129 recognized species, 101 are found in marine costal habitats of Antarctica (Fig. 1), and the remaining species are distributed along costal areas of southern South America, the Falkland ...

Osteological development of the Channichthyidae (Teleostei: Notothenioidei)
1997The osteological development of eight species (Champsocephalus gunnari Loennberg 1905, Channichthys rhinoceratus Richardson 1844, Pseudochaenichthys georgianus Norman 1937, Pagetopsis macropterus (Boulenger 1907), Chionodraco rastrospinosus DeWitt & Hureau 1979, Chaenodraco wilsoni Regan 1914, Chaenocephalus aceratus (Loennberg 1906) and Cryodraco ...

Journal of Morphology, 2003
AbstractIn the subzero shelf waters of Antarctica, fishes of the perciform suborder Notothenioidei dominate the fish fauna and constitute an adaptive radiation and a species flock. The 16 species of dragonfishes of the family Bathydraconidae live from surface waters to nearly 3,000 m and have the greatest overall depth range among notothenioid families.

Comparative Biochemistry and Physiology Part A: Physiology, 1997
Traditional karyotyping and molecular cytogenetic techniques were used to study the chromosomes of Champsocephalus gunnari from the Indian Sector of the Antarctic Ocean. C. gunnari has 24 pairs of chromosomes, giving a diploid number of 48. Most are acrocentric, six are metacentric and submetacentric and the level of divergence from the supposed ...

Confirmation of neutral buoyancy in Aethotaxis mitopteryx DeWitt (Notothenioidei: Nototheniidae)
Polar Biology, 2006Aethotaxis mitopteryx is a nototheniid species with a circum-Antarctic distribution in the Southern Ocean. We present new locality records, buoyancy measurements, and morphometric data on five A. mitopteryx specimens collected from the Bransfield Strait. Our analyses demonstrate that A. mitopteryx is neutrally buoyant.

Early life stages of Notothenioidei from the Kerguelen Islands
1990Morphology, meristics and pigmentation have been used in combination with knowledge of adult reproduction and habitat to identify larvae of Notothenioidei from the Kerguelen Islands. The larvae have been collected regularly with plankton since 1986. Eleven species belonging to this suborder occur in the Indian sector of the Southern Ocean.
