Dramatic changes in seabird and marine mammal stocks in the Gulf of Alaska have been linked to shifts in abundance and composition of forage fish stocks over the past 20 years. The relative value (e.g., size and condition of individual fish, abundance) of specific forage fish stocks to predators under temporally changing oceanographic regimes is also ...

Abstract Pacific Sand Lance (Ammodytes personatus) are energy-rich schooling fish that are thought to be important drivers of marine food webs in Alaska (USA) and British Columbia (Canada). Despite a number of studies characterizing their distribution and habitat use in Alaska and British Columbia, surprisingly little is known about population ...

We determined whether, during the summers of 2002–2004, young-of-the-year (YOY) Pacific sand lance (Ammodytes hexapterus) re-used patches of sediment in intertidal and shallow subtidal regions of Barkley Sound, British Columbia, Canada. We examined re-use weekly at a single sediment patch in 2003 and 2004 via mark-recapture methods, monthly by re ...

Abstract Pacific sand lance (Ammodytes hexapterus), an important prey species for many vertebrate predators in the northeast Pacific, lacks a swim bladder and relies on coarse sand substrates to bury in overnight and during the winter. Surprisingly little information is available describing the spatial distribution and extent of its burying habitat ...

Variation in the diet of the Pacific sand lance Ammodytes hexapterus was examined in three years (2009–2011) at four sites in British Columbia, Canada. There were 12 major taxa of prey in diets, eight of which were Crustacea, with copepods being by far the dominant taxon in all 12 site‐years. Of the 22 copepod taxa recorded, only Calanus marshallae and

ABSTRACTThree waves of spawning Pacific sand lance (Ammo‐dytes hexapterus) entered the Port Moller estuary from mid‐January to late May 1990. Each wave laid its eggs on sand in lower Moller Bay with the center of egg distribution about 14 km inside the estuary.

Vancouver BC is one of the most rapidly growing cities in Canada. With an abundance of coastal waters and shore lines and its population only set to increase in the next decades, it is important to assess the impacts that increasing urbanization will have on important coastal marine ecosystems. Intertidal zones and beach shore front provide significant

Behavioural Processes
Environmental conditions influence the condition and survival of organisms and may influence levels of activity, relative condition, and mortality rates. Temperature has a direct effect on energetic demands associated with activity and rest and temperature-mediated physiological rates.

The Pacific sand lance (Ammodytes hexapterus) is an ecologically important prey species for many vertebrate marine predators in the Pacific Northwest. In this study, we examined the use of intertidal habitat by young of the year (YOY) sand lance in Barkley Sound, British Columbia.

Data on the spatiotemporal distribution, size-age structure, individual fecundity, and food composition of the Pacific sand lance Ammodytes hexapterus in waters off Kamchatka in the Sea of Okhotsk in the summer months are provided. It is shown that, on the western Kamchatka shelf, this species is found uniformly at depths smaller than 100 m in the ...
