Ptilocrinus amezianeae is a Vulnerable Marine Ecosystem (VME) indicator species and often collected in numbers locally. P. amezianeae has been described to be restricted to oligotrophic habitats and, as a member of the family Hyocrinidae, a rare organism. Here we model P. amezianeae suitable habitat using BRT (Boosted Regression Trees) and an iterative approach to identify areas on the Kerguelen Plateau, north and south, that could need additional protection. We identified one area under strict protection on the Skiff Bank, and two additional areas, one in the northeastern Kerguelen Plateau and the other on William’s Ridge.
Abstract:
A collaborative research program has been undertaken by Japan and South Africa since 2013 to enhance data collection and analysis in the subarea 48.6. From the last season (2018/19) Spain has joined the proposal in order to contribute to the data acquisition and to speed up the integrated assessments of the D.mawsoni stock in this subarea (FSA-18/34).
The continuation of the three-member research proposal for 2019/20 season is presented to ensure continuity of previous research activities. Data and investigations about the population structure and various demographic parameters of Antarctic toothfish (Dissostichus mawsoni) using trotline (JPN and ZAF) and Spanish longline (ESP) gears, established tagging techniques, pop-up tags and genetic analysis will provide the basis for the development of spatial population models and assessments in support of management advice. An Integrated Stock Assessment (ISA) of this species is expected to be done by the end of the 2020/21 season.
Additional outcomes of the research include documenting relative abundance of Antarctic and Patagonian toothfish, tagging toothfish for biomass estimation and for stock linkage studies, and collecting information on distribution, and life history of bycatch and Vulnerable Marine Ecosystems (VMEs).
In discussion with the Chairs, this preliminary timetable has been produced to allow both SCIC and SCAF to hold their meetings in the Wombat Room. Interpretation is available in the Wombat Room, but not in the Basement Room. The avoidance of major overlapping sessions of SCIC and SCAF should enable small delegations to engage more easily with these Committees.
Visual observations of cetaceans were conducted aboard the Ukrainian krill fishing vessel More Sodruzhestva. Observations were made during December 2018 – to January 2019 in Subareas 48.1 and 48.2. 66 baleen whale registrations were recorded. Whale’s behavior was observed and analyzed.
Abstract:
The Marine Mammal Protected Areas Task Force (MMPA Task Force) was established in 2013 by the International Committee on Marine Mammal Protected Areas (ICoMMPA), the International Union for Conservation of Nature (IUCN), the Vice-Chair of the World Commission on Protected Areas (WCPA), and the Members of the IUCN Species Survival Commission (SSC).
This group organises scientific workshops whose objective is to identify and delimit habitats that are considered important for one or more marine mammal species, and which have the potential to be managed in terms of species/habitat conservation. The identified "Important Areas for Marine Mammals" (IMMAs) make it possible to put in place localised protection and/or monitoring measures, or simply zoning within existing and future marine protected areas (MPAs).
The objective of this document is to present the scientific protocol for the identification of IMMAs and the programme for identification in the marine regions of the world, to the scientific experts associated with the working groups of the CCAMLR Scientific Committee. IMMAs have the potential to be used as information layers in the designation of areas that deserve particular attention in terms of conservation.
