Habitat characteristics of an intertidal aggregation of Pacific Sandlance
(Ammodytes hexapterus) at a North Puget Sound beach in Washington.
Changes in pelagic fish species include a shift from an abundance of Arctic cod (Boreogadus saida) to an increase in sub-Arctic species such as capelin (Mallotus villosus) and sandlance
Ammodytoides xanthops, a new species of sandlance
(Perciformes: Ammodytidae) from Mozambique.
Many bottom-dwelling Adult and juvinile fish such as cod, yellowtail pounder, winter skate, Northern sandlance
, redfish (pictured) and longhorn sculpin thrive within this area.
Mixed species aggregations feeding upon herring and sandlance
schools in a nearshore archipelago depend on flooding tidal currents.
typical food for humpback whales is a small shrimp-like zooplankton, called krill, and schooling fish, such as herring, sandlance
Their distribution is driven by the habitat preferences of their prey, presently sandlance
, Ammodytes spp.
Because the Common Terns of the Portneuf sandbar fed exclusively on sandlance
(Ammodytes americanus), I estimated E via Harris and Hislop's (1978) allometric relationships for sandlance
that convert total length to mass and then predict energy value as a function of mass.
At site 2, of the 315 lingcod stomachs sampled, 177 were empty and 138 contained the same 10 prey categories plus Pacific sandlance
(Ammodytes hexapterus) as a major prey item, as well as market squid (Loligo opalescens), Pacific lamprey (Lampetra tridentata), and northern anchovy (Engraulis mordax) as minor items (Table 2).
The incidence of arctic cod, sculpins, and benthic Zoarcidae decreased and the incidence of capelin and sandlance
increased over the period considered.
fish and chameleons) have hit on a similar solution to the problem of monocular rangefinding (Ott and Schaeffel, 1995; Pettigrew et al.
Among the larvae, Pacific sandlance
(Ammodytes hexapterus), rex sole, and curlfin sole (Pleuronichthys decurrens) were tightly clustered, as were northern anchovy and thornyheads (Sebastolobus spp.
