Abstract

Juvenile fishes of the family Nototheniidae were recorded during fishing for krill eastwards of the Balleny Islands. The paper describes juveniles of the most abundant species. Trematomus bernacchii and Pagothenia brachysoma, their distribution and abundance. Also the correctness of assigning of some juveniles to the species T. bernacchii is discussed.

Abstract

The shelf fishing grounds of Kerguelen Islands and of some neighbouring ocean shallows were studied in April 1975. The occurrence of 15 species representing 9 families was found in the catches. Detailed study of the following five species was performed: Champsocephalus gunnari, Channichthys rhinoceratus, Notothenia rossi rossi, N. squamifrons and Dissostichus eleginoides, all of potential commercial importance. The boundaries of regions with concentrations of Ch. gunnari and N. squamifrons were determined, the productive and suitable for trawling fishing grounds were localized.

Abstract

During the SIBEX1' programme in December 1983/January 1984, 27 hauls were made from the "Profesor Siedlecki" with a 368 — mesh midwater sampling trwal. A total of 13 fish species at postlarval or juvenile stages was found in the catches. The greatest aboundance and species diversity of juvenile ichthyofauna was observed within shelf waters of the Peninsula. Postlarval and juvenile Pleuragramma antarcticum was the most common and most aboundant species there.

Abstract

Observations on abundance and distribution of juvenile fish within the krill concentrations were made during February—March 1981. Juvenile and scarce postlarval stages belonging to 23 species of the suborder Notothenioidei were recorded in the investigated area. Chionodraco rastrospinosus and Chaenodraco wilsoni were the most frequent and numerous species. Juvenile fish, as well as extensive concentrations of krill, were recorded mainly in the southern part of the Bransfield Strait and in the shelf waters westwards of the Palmer Archipelago. The juveniles were however absent in the open waters of the Drake Passage.
