Small pelagic fish (SPF) play an important ecological role by facilitating energy transfer in marine ecosystems, from lower to higher trophic levels. The Celtic Seas ecoregion is home several economically SPF that spend some or all their life these waters. In recent decades, major changes the relative abundances of 6 main region (anchovy, herring, horse mackerel, sardine, and sprat) have been o...

variability, in particular relating to ENSO events. Off California, anchovy spawning expands northwards during El Niño events (Checkley et al., 2009). Likewise, the northern limit of California sardines in Canadian waters is broadly related to sea surface temperature, expanding north during the months of June through August and returning south when sea temperatures begin to cool (McFarlane et a...

Using implanted archival tags, we examined the effects of meal caloric value, food type (sardine or squid) and ambient temperature on the magnitude and duration of the heat increment of feeding in three captive juvenile Pacific bluefin tuna. The objective of our study was to develop a model that can be used to estimate energy intake in wild fish of similar body mass. Both the magnitude and dura...

Metal and element concentrations (Li, Na, Mg, P, Ca, V, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Mo, Pd, Cd, Cs, Ba, Hg, Tl, Pb, U) were monitored in the tissues of sardine (Sardina pilchardus) anchovy (Engraulis encrasicolus) from six Greek coastal areas subjected to different natural anthropogenic forcings order be assessed as bioindicator species marine metal pollution. Sardine provided a...

OBJECTIVE The study evaluated the effect of a canned sardine supplement in C-reactive protein (CRP) in patients on hemodialysis (HD) and the compliance and adherence to this supplement. DESIGN This was a quasi-experimental study: Participants with a serum CRP of 5 mg/dL or less volunteered to consume a sardine supplement or were maintained on the usual cheese/ham sandwich supplement. SETTIN...

Although modern beaked whales (Ziphiidae) are known to be highly specialized toothed whales that predominantly feed at great depths upon benthic and benthopelagic prey, only limited palaeontological data document this major ecological shift. We report on a ziphiid-fish assemblage from the Late Miocene of Peru that we interpret as the first direct evidence of a predator-prey relationship between...

This study described the phenology and patterns of variability of forage fish and mesozooplankton populations near the Columbia River plume. Our objective was to identify the timing of the seasonal appearance of forage fish and to characterize the temporal patterns of abundance in relation to ocean conditions including zooplankton availability. Observations were collected at 2 stations in 2008 ...
