ABSTRACT The sustainable advancement of aquaculture can be supported using functional feed ingredients with immunomodulatory activity. These studies evaluated the immunonutritional effects of dietary nucleotides (NU) and an olive bioactive extract (OE) in Pacific white shrimp (PWS), Penaeus vannamei. A 56‑day growth trial (n = 1000 PWS; PL42‐43; 1.23 ±

On the Estimation of Zooplankton-Mediated Active Fluxes in Oxygen Minimum Zone Regions
In the Peruvian upwelling system, the mesopelagic oxygen minimum zone (OMZ) is the main vertically structuring feature of the pelagic habitat. Several zooplankton and nekton species undertake diel vertical migrations (DVMs) into anoxic depths.

Piscivorous fish patrol krill swarms [PDF]
Journal homepage: http://www.int-res.com/journals/meps/Dense swarms of the krill Meganyctiphanes norvegica in the Norwegian Sea were patrolled by large, piscivorous fish, which apparently use the krill swarms as feeding grounds in their hunt for ...

The Antarctic krill Euphausia superba is a key species in Antarctic waters, mainly because it is a major component of the diet of dominant predators, including penguins. It is also a marine living resource that is commercially harvested.

Responses of Antarctic seabird populations to past climate change
Higher‐order predators such as Antarctic seabirds serve as ecological indicators of environmental change and provide a crucial trophic link between marine and terrestrial ecosystems. Despite their prevalence and significance in the Antarctic ecosystem, there is a lack of understanding of the impacts of major regime shifts in paleoclimate on flighted ...

Characterisation of the Pump-Suction Flow Field of Antarctic Krill and Key Influencing Factors
To address the problem of high damage rates and low efficiency during Antarctic krill pumping, this study used Discrete Phase Modelling (DPM) computational fluid dynamics (CFD) to analyse how krill–water mixing ratios and centrifugal pump speeds affect ...

Hypoglycemic Effect of Astaxanthin Oil–Fish Oil Complex in Mice With Type 2 Diabetes
This study demonstrates that an astaxanthin oil–fish oil complex exerts synergistic hypoglycemic and hepatoprotective effects. It enhances glucose metabolism and relieves oxidative stress in insulin‐resistant HepG2 cells. In high‐fat diet mice, the complex reduces hyperglycemia, improves lipid profiles, and attenuates hepatic steatosis and pancreatic ...

Bycatch of fish in the South Atlantic krill fishery
Icefish (Champsocephalus) were taken as bycatch during krill fishing operations from a research vessel. The data indicate that the bycatch of fish in the commercial krill fishery may be significant in some areas of the South Georgia shelf. The problem is
