Swath-Mapping and Related Deep-Sea Trawling in the Southeastern Part of the Economic Zone of New Caledonia, in Séret B. & Sire J.(Eds), Proceeding 5th Indo-Pacific Fisheries Conference, Nouméa: 459-468
Within the framework of the programme "ZoNéCo" of evaluation of the marine resources of the economic zone of New Caledonia, a series of operations were completed in the southeastern part of Ihe economic zone. The first was a balhymetrical and geophysical survey of the major part of the Norfolk Ridge and the southem end of Ihe Loyalty Ridge. The data obtained on this survey provided a base for the preparation and completion of the deep-sea trawling survey "HALIPRO 2", the main objective of which was 10 search for commercial quantities of deep-sea fish, primarily orange roughy (Hoplostethus atlanticus). During this survey, 106 hauls were made between 230 and 1,860 m depth. A total catch of 263 fish species was made belonging to 192 genera and 101 families. In particular, 37 species of sharks and rays were collected of which 40% are new to science. The results confinn the extreme specific richness of the deep-sea ichthyofauna and the presence of species of commercial interest such as the alfonsino, Beryx splendens. However, orange roughy, was not located.
