A study was conducted at Yaquina Bay, Oregon, to determine
the age-fecundity relationships in the striped seaperch Embiotoca
lateralis. A questionnaire was sent to California, Oregon, and
Washington to ascertain what regulations were in effect, and the value
of the family Embiotocidae with regard to the sport and commercial
harvest....
Seventeen populations of Gila Baird and Girard are identified from the Alvord Basin of southeastern Oregon and northwestern Nevada. Gila in the Alvord Basin occupy a wide range of habitats, including warm springs, cool springs, creeks, reservoirs, and a thermal lake. These populations became isolated in remnant habitats when waters...
Based on the number of velar tentacles and the form of longitudinal
lingual laminae found in Lampetra (Entosphenus) t. tridentata
and its closely related forms, the taxon Entosphenus should not be
considered as a genus as commonly adopted, but, along with the taxa
Lethenteron and Lampetra, should be regarded as...
The taxonomic placement of Gadopsidae is discussed and an evaluation of its osteological relationships with related families is given. Similarities to the more primitive genera of the trachinoids, notothenioids, and uranoscopoids are noted and the inclusion of Gadopsidae in the Trachinoidae is recommended. A description of the geological history of...
A theory of the origin and distribution of fishes in the Harney Basin is presented. Blitzen River, the hydrographically and ecologically isolated creeks, and the upland tributaries of Silvies River all contain populations derived from the basin's Pleistocene connection with Malheur River of the Snake system. Colonization of many streams...
Complete, identified, developmental series of larval cottids
Artedius fenestralis, A. creaseri, A. meanyi, Oligocottus snyderi,
Clinocottus embryum, and C. globiceps are described for the first
time. In addition, redescriptions of four species, Artedius harringtoni,
A. lateralis, Oligocottus maculosus, and Clinocottus acuticeps
are included that provide new and comparative information on...
