Peggy H. Ostrom William Walker Patrick J. Gould 1997 <p><span>We examined digestive tract contents and stable nitrogen isotope ratios in breast muscles of Flesh-footed Shearwaters </span><i>Puffinus carneipes</i><span> associated with high-seas driftnet fisheries in the central North Pacific Ocean. Small fish, Lanternfish (Myctophidae) and Pacific Saury </span><i>Cololabis saira</i><span>, were the principal prey found in the digestive tracts. Pieces of unidentified fish, possibly Pacific Pomfret </span><i>Brama japonica</i><span>, and shredded squid tissue, mostly Neon Flying Squid </span><i>Ommastrephes bartrami</i><span>, in the digestive tracts indicate scavenging at driftnet fishing operations. Although soft-bodied animals such as </span><i>Velella</i><span> sp. were rare in the digestive tracts, low stable nitrogen isotope values (δ</span>¹⁵<span>N) suggest Flesh-footed Shearwaters feed heavily on such low trophic level animals.</span></p> application/pdf 10.1071/MU97020 en Taylor & Francis Food of Flesh-footed shearwaters <i>Puffinus carneipes</i> associated with high-seas driftnets in the central North Pacific Ocean article
