Features of spatial and temporally distribution patterns of krill flux in the Scotia Sea: some comments on the development of a krill fishery management in Area 48.
Abstract: The spatial variability of krill flux in the Scotia Sea calculated by using the ... distribution of krill density, water flow intensity (m 3 /s) and krill biomass (g/m3) transported by water flow ... to the Scotia Sea, were a subject of study. It is clearly illustrated that the geostrophic krill ... flux in the Scotia Sea requires both favorable dynamic conditions and availability of krill transported ...

MaxEnt reconstructions of krill distribution and estimates of krill density from acoustic surveys at South Georgia 1996–2000
Abstract: We present Maximum Entropy (MaxEnt) reconstructions of krill distribution and estimates ... of mean krill density within two survey boxes of dimensions 80 km x 100 km to the north east and ... gathered in the boxes in austral summers 1996 – 2000. Krill densities had previously been determined at ... 1600 krill density estimates per box. The MaxEnt technique uses a Bayesian approach to infer the most ...

Krill distribution pattern due to water structure and dynamics near the South Sandwich Islands in January–February 2000 (Krill Synoptic Survey 2000)
krill distribution is carried out. There are determined three krill groups which differ each other by ... length frequency, maturity stages and waters inhabited. Distribution of the 1st krill group (juveniles 25 ... concentration of krill of the 3rd group (50-56 mm) transported there by ACC waters.

A model at the level of the foraging trip for the indirect effects of krill (Euphausia superba) fisheries on krill predators
krill (Euphausia superba) predators, using the Adelie penguin (Pygoscelis adeliae) as a model organism ... . The model involves: (i) the description of the biomass and spatial distribution of krill; (ii) the ... effects of the fishery on the krill; (iii) the description of penguin breeding; and (iv) the indirect ... biomass of krill appropriate for the predators (and the fishery) fluctuates from one year to the next ...

Modelling growth and reproduction of Antarctic krill: implications of spatial and temporal trends in temperature and food for ecosystem-based management of krill fisheries
Abstract: Errors in the growth model used in stock assessments of Antarctic krill, specifically ... higher rates of growth than occur in reality, could inadvertantly lead to over-exploitation of the krill ... population and cause impacts on krill predators. We review the three classes of models available for ... modelling krill growth – the von Bertalanffy class, the moult-cycle class based on measures of the duration ...

Winter habitat selection by Antarctic krill will increase krill-predator-fishery interactions during ice free years
Antarctic krill (Euphausia superba), a key forage species (Laws 1977; Smetacek and Nicol 2005) and a target ... et al. 2014; Atkinson et al. 2004) and is likely to increase krill-predator-fishery interactions ... estimates of krill biomass, habitat use, and association with top predators to examine these likely ... interactions. Krill were virtually absent in offshore waters of the Drake Passage during all three winters ...

Successful ecosystem-based management of Antarctic krill should address uncertainties in krill recruitment, behaviour and ecological adaptation
Abstract: Antarctic krill, Euphausia superba, supports a valuable commercial fishery in the ... Southwest Atlantic, which holds the highest krill densities and is warming rapidly. The krill catch is ... main goal of safeguarding the large populations of krill dependent predators. Here we show that ... , because of the restricted distribution of successfully spawning krill and high inter-annual variability in ...
