Observations of seabirds in Macquarie Island waters (1999)

Latest version published by CSIRO Oceans and Atmosphere on Nov 8, 2019 CSIRO Oceans and Atmosphere

Thi survey is a first attempt at determining the distribution and relative abundance of all seabird species occurring in Macquarie Island waters, especially in relation to the main bathymetric and oceanographic features of the study area, namely the Macquarie Ridge and Subantarctic Front, respectively. To this end, observations of seabirds were made by the author from aboard the CSIRO Research Vessel Southern Surveyor while it conducted acoustic, trawling and benthic surveys in the waters immediately round Macquarie Island and northwards along the Macquarie Ridge during 14-31 January 1999.

The nine main sites within the study area and the distribution of seabird counts at each site are shown in Figure 1 (see Appendix 4 of https://www.frdc.com.au/project?id=1942). Most observations were made over the relatively shallow waters of the main part of the Macquarie Ridge i.e. close inshore off the east and west coasts of the island and northward along the ridge to the southern edge of the Subantartic Front Gap (sites 2-5). Additional observations were made in shallow waters well south of the island at the southernmost part of the ridge (site 7), and at two other ridge sites north of the Subantarctic Front Gap (sites 8 and 9). Observations were also carried out at two deep-water (pelagic) sites: at site 6 in waters c.25 miles west of Aurora Trough, and at the Subantarctic Front Gap (site 1) immediately north of the main north-south ridge through the island.

Project Data

The Patagonian toothfish fishery is expanding worldwide and it may play a pivotal role in the development of an Australian fishing industry in the Southern Ocean. The recommended TAC for toothfish in other Southern Ocean regions was revised upwards by the 1996 CCAMLR scientific committee. For example, in the CCAMLR area 58.5.2 (primarily the AFZ around Heard and McDonald Islands) a TAC of 3800 metric tonnes of toothfish was set. As a result considerable national and international interest in the fishery is expected. Given the conservation value of Macquarie Island it is expected that operation of the fishery will be closely scrutinised -- the scrutiny is already clear at the national ( MACSAG, AFMA, DPIE and conservation groups) level. Development of the Macquarie Island fishery provides a great opportunity as a demonstration project to illustrate that fishery development can be achieved while protecting conservation values -- a demonstration of Ecologically Sustainable Development in action. Furthermore, much of what will be learnt will also be relevant to the emerging Heard Island toothfish fishery. To date little research has been done to establish the basic biological parameters of the toothfish necessary to develop sound management policies. As recognised by both the Macquarie Island Fish Stock Assessment Group and the Sub-Antarctic Ecosystem Assessment Group there is a real need to develop a comprehensive program of research which not only addresses basic biological parameters such as age and stock structure, but also examines the distribution and abundance of this species so that effective management of the fishery can proceed. As the Macquarie Island area is likely to be sensitive to possible ecosystem changes brought about by a developing fishery, there is also a need to understand where toothfish 'fit into' the broader offshore Macquarie Island ecosystem, and likely ecosystem effects.
