shrimps, amphipods, copepods, cumaceans
, and ostracods) and soft-tissue prey (e.
and oligochaetes were also recorded at station 4, while polychaetes only at stn.
The most frequently seen prey items were copepods, cumaceans
, and zoea larvae.
In spring and summer 02, cumaceans
and amphipods were the most important item ingested, and also polychaetes and brachyurans were found abundantly (Table 1).
The non-productive fraction of the microbiota ("microfauna") consists of bacteria, diatoms, flagellates, and ciliates (3-328 ft [1-100 m]); the meiofauna (328-3,281 ft [100-1,000 m]) is rich in foraminifers, nematodes, turbellarians, gastrotrichans, cumaceans
, copepods, and the juvenile phases of macro-invertebrates.
Although some prey items, including mysids, gammaridean amphipods, and cumaceans
, were consumed regularly, most prey types were infrequently observed in the stomachs of southern kingfish (Fig.
nudigula, while shrimps (IRI = 335) and cumaceans
(IRI = 280) to P.
The material collected is the most complete record of the macrobenthos inhabiting a Canadian high arctic fiord: polychaetes, molluscs (gastropods, bivalves, scaphopods), crustaceans (amphipods, cumaceans
, isopods, shrimp), pycnogonids, bryozoans, and echinoderms (echinoids, holothurians, ophiuroids) are represented in the collections.
nondecapod crustaceans (including amphipods, isopods, cumaceans
, mysids, and mantis shrimp), bivalves (clams and periwinkles), fishes (44 species identified), worms and wormlike organisms (nematodes, polychaetes, annelids, and leeches), and other unidentified (UID) items (inorganic matter, organic matter, eggs, and insects).
The most important prey found in both species were polychaetes, amphipods and isopods, while cirripeds, crabs, cumaceans
, brittlestars and mollusks were the less consumed prey; for this reason these prey were grouped together for analysis as "other prey".
The benthic prey comprised a variety of fishes and crustaceans including amphipods, cumaceans
, mysids, shrimps, nematodes, nemerteans, and polychaetes (Table 4).
In zooplankton samples, cumaceans
were not enumerated.
