This document presents the analysis of acoustic data obtained during the austral summer of 2018 as a complement to finfish research in Subareas 48.1 and 48.2 using bottom trawling nets. The acoustic information survey was carried out with a SIMRAD EK80 wide band scientific echosounder at a frequency of 38 kHz and a SIMRAD ES70 fishing echosounder equipped with a 120 kHz frequency transducer. The geographical distribution of krill concentrations and the presence of fish shoals are described in an area of 1,699 nautical miles over the continental shelf and slope (50-500 m) around Elephant Island (579 nm) and South Orkney Islands (1,120 nm). Concentrations of krill (Euphausia superba), the pelagic species with the greatest presence in the studied area, are described, mainly to the north of both islands. Likewise, mackerel icefish (Chamsocephalus gunnari) are identified, forming large concentrations in steep slope areas, mostly around Elephant Island. This species presents demersal characteristics during the day and pelagic characteristics at night. Additionally, some echoic records registered in the water column are presented, attributed to "Other species" of fish.

It is shown that   the proposals for the establishment of an MPA in the Weddell Sea should be complemented by information on the commercial potential and future rational use for dominant fish species and krill  in the Subarea 48.5 and 48, 6.  

The areas for fishing activity and protection areas  in the Weddell Sea  should be managed by separate Conservation Measures.

It is shown that the WS MPA boundaries should be revised in compliance with sea-ice conditions for vessel navigation being a fundamental factor for the successful completion of assigned research tasks in designated areas.   Spatial planning in the Weddell Sea should make provisions that ice-free areas are areas for planning MPAs and fishing activities

A new fish leech Ambulobdella shandikovi n. g., n. sp. (Hirudinida: Piscicolidae), a parasite of Whitson’s grenadier Macrourus whitsoni (Regan) (Macrouridae: Gadiformes) collected in the Ross Sea at depths from 1,221 to 1,433 m, is described and compared with related taxa based on morphological and molecular characters. Ambulobdella shandikovi n. sp. is characterised by prominent segmental tubercles on the venter and dorsal segmental tubercles, an uncommon appearance of its anterior sucker with earlike edges and an inner membrane around the mouthpore, well-developed musculature and a unique combination of features of the reproductive and digestive systems. The presence of uncommon tubercles can be attributed, in part, to temporary associations of A. shandikovi n. sp. with its fish hosts and a need for well developed sensory and locomotory organs. A certain locomotory function of ventrolateral tubercles of A. shandikovi n. sp. is hypothesised and discussed. Further deep-sea surveys are obviously needed to shed light on the behaviour and mode of locomotion of this species.

In the fishing season of 2018, three Ukrainian fishing vessels SIMEIZ, KOREIZ, CALIPSO collected oceanographic data (salinity and temperature) in Subareas 88.1, 88.2, 48.2. Some preliminary results presented.

In the stomachs of caught Dissostichus mawsoni, specimen of the Dissostichus species with tag found.

The multi-year variability of the Patagonian toothfish (Dissostichus eleginoides) size composition in longline catches in the South Georgia maritime zone   in context of  the fishery  management is discussed.

En 2017, le SCAF a chargé le secrétariat d'effectuer une évaluation de son plan stratégique et de sa stratégie salariale et de dotation en personnel. Le retour d'information interne et externe pendant l'évaluation est en faveur d'un accroissement de la proportion de postes internationaux au secrétariat et du renforcement des fonctions de gestion des données, de gestion des pêcheries, des fonctions scientifiques et de la gestion des ressources humaines pour répondre aux besoins actuels et futurs de l'organisation. Le secrétariat propose un nouveau plan stratégique pour apporter ces changements, pour restructurer et renforcer ces fonctions au sein du secrétariat, pour accroître la proportion de personnel international qui de 12% en 2018 passerait à 35% d'ici à 2022 et à 50% d'ici à 2028, et pour modifier la stratégie salariale et de dotation en personnel et le Statut du personnel afin de les mettre en conformité avec les pratiques actuelles locales et de la CFPI.

Conformément au paragraphe 2 i) de la MC 10-10, le secrétariat a préparé un rapport CCAMLR de synthèse de la conformité (rapport de synthèse) sur la base des projets de rapports CCAMLR de conformité (projets de rapport), des réponses reçues des Parties contractantes et des statuts de conformité préliminaires qu'ils ont suggérés. Les rapports de synthèse ont identifié 10 écarts potentiels de conformité avec les mesures de conservation, impliquant 7 Parties contractantes. Le secrétariat a distribué les projets de rapport le 8 août 2018, avant la réunion de la Commission. Le rapport de synthèse renfermant les réponses des Parties contractantes figure en annexe 1 au présent document.
