Eight scale characters of known hatchery and wild coho salmon
(Oncorhynchus kisutch) were compared, and a linear discriminant
function was used to determine if hatchery and wild adult coho
salmon could be correctly identified by their scales. Eighty-two
percent of the hatchery and 89% of the wild fish were correctly...

Sampling with seine and trawl from May 1974 to November 1976 indicated that the species composition and distribution of fishes in Tillamook Bay through time is primarily related to the movements of marine species in and out of the estuary. Northern anchovy (Engraulis mordax), surf smelt (Hypomesus pretiosus), and shiner...
Pineal hydroxyindole-0-methyltransferase (HIOMT) activity
was monitored over a 24 h period under three different photoperiods,
16L:8D, 8L: 16D, and 12 L:12D. It was observed that in all three
groups of fish HIOMT activity was high' during the dark portion of the
photoperiod in comparison to activity during the light portion....
Observations of temperature between 20 and 40 m depth were made with a towed thermistor chain in the North Pacific (50N, 145 W) during the Mixed Layer Experiment (MILE). The chain was usually towed at a speed of 3 m/s around a 20km square on alternate days for a three-week...
