Abstract This paper reviews some of the distributional features of vertically migrating micronekton
off Oregon; describes a new, conducting-cable, midwater-trawl system using an eight-net,
opening-closing cod-end unit; and gives some preliminary results on trawl catches relative to
sound-scattering layers.
A variable complex of organisms, including euphausiids, a sergestid shrimp, and mesopelagic
fishes, was often common in 12- and 38.5-kHz scattering layers. The depth range of
many species was broad, and sometimes the largest catches were made at depths above or below
scattering layers. Variability was large among nets that fished either horizontally or vertically
during single tows.
