Data from this small sample reflected the importance of euphausiids in the diet of Cassin's Auklets during the early part of the breeding season, as in Ancient Murrelets foraging off Langara Island before fish assumed greater importance later in the breeding season (Sealy 1975).
2010) near Barrow, Alaska, where euphausiids and copepods near the shelf break are advected onto the shelf northeast of Point Barrow under certain wind conditions (Citta et al, in press).
In particular, sardines are known to feed more heavily on cyclopoid copepods (usually <200 gm) while anchovy feed more on largercalanoid copepods and euphausiids (James, 1987; Konchina, 1991; Van der Lingen, 2002).
Robinson and Ware (1999) used the simple regression between temperature and Pacific hake biomass that Ware and McFarlane developed to help parameterize a one-dimensional trophic model of the pelagic ecosystem in the La Perouse Bank region, in which inter-annual variability in predator-prey relationships between Pacific hake, herring, and euphausiids were important.
The whales grow to be about 60 feet long and weigh up to 75 tons, thanks to a diet of copepods, euphausiids, and other small invertebrates.
Abstract: The zooplankton community structure, including copepods, euphausiids, chaetognaths, and decapod larvae, was monitored during six circadian cycles using Bongo net (500 [micro]m mesh net) samples from Bahia Magdalena, on the southwest coast of Baja California, Mexico.
This difference in biomass is largely explained by the presence of large oceanic populations of euphausiids (krill), which can account for more than 30% of the zooplankton biomass.
Observations of a mixed-species flock of birds foraging on euphausiids near St.
Metabolism and body composition of two euphausiids (Euphausia superba and E.
This finding challenged the previously established paradigm that grazing by large copepods and euphausiids in upwelling systems represents the major pathway for transferring primary production to fish (Riley, 1947).
For the CART analysis, all mollusks were grouped together, as were all euphausiids, and all cyclopoid copepods.
Plankton samples were comprised of primarily crustaceans (copepods, amphipods, euphausiids, and decapod (brachyuran, pagurid, caridean) larvae) and chaetognaths with some polychaetes, gastropods, cnidarians, echinoderm larvae, and fish larvae and eggs; no red, blue, or golden king crab larvae were present.
Similarly, euphausiids and copepods are the main prey of bowheads in the Alaskan Beaufort Sea in spring (Lowry et al.
Pelagic young feed small crustaceans (Ven Tresca 1992), and adults prey on other fishes (anchovies, lanternfishes, small rockfishes), octopi, squids, krill (Love 1996), and crustaceans as euphausiids, copepods, mysids, amphipods and carideans (Lea et al.
