THE OCEANIC SHRIMP SERGESTES SIMILIS OFF THE
Sergestes similis is the most abundant pelagic shrimp in modified subarctic waters off Oregon and the northeastern Pacific Ocean. Off Oregon, its distribution changes with season and distance from shore. Largest numbers were caught in waters over the conti-nental slope in 6-ft midwater trawls and I-...
