1. SPATIAL PATTERNS IN MACKEREL ICEFISH DIET PROVIDES INSIGHTS INTO KRILL ABUNDANCE AND DISTRIBUTION

   Abstract:  The diet of mackerel icefish was investigated from stomachs of 828 fish caught on the ... South Georgia and Shag Rocks shelves in January 2009. The results show that the diet of this normally ... krill-dependent species was dominated by the hyperiid amphipod Themisto gaudichaudii (92 % IRI) and was ... low in Antarctic krill (7 % IRI) compared with similar data for the same month in 2004-2006. The ...

   Abstract:  An age-length key was prepared for Champsocephalus gunnari from the Subarea 48.3, based ... on the readings of otoliths randomly collected during the R/V Holmberg survey in Feb/Mar 1994. Small ... and medium sized fish (total length 12-33 cm) constituted the bulk of the samples (93%), while larger ... Rocks, a large concentration of fish belonging to age groups 2 (90%) and 3 (10%) was found. The length ...

4. Preliminary tag-recapture based population assessment of Antarctic toothfish (Dissostichus mawsoni) in Subarea 48.4

   Abstract:  The biomass of Antarctic toothfish (D. mawsoni) in CCAMLR subarea 48.4 is estimated ... 1187 tonnes. Applying the CCAMLR agreed precautionary assumption of average biomass across the time ... series and harvest rate of γ = 0.038, implies a 2019/20 yield of 45 tonnes using the 5-year average ... biomass. Historically, a precautionary approach has been applied in treating the 48.4 Antarctic toothfish ...

5. Report from a krill- focused survey with RV Kronprins Haakon and land-based predator work in Antarctica during 2018/19

   Abstract:  The primary objective for this krill research activity was twofold 1) to conduct a ... survey that provides updated estimates of the biomass and distribution of krill which are used in models ... to estimate sustainable yield in CCAMLR Area 48 and 2) to develop knowledge on the marine environment ... essential for the implementation of a Feed-Back Management (FBM) system. The survey follows a similar design ...
