Summer spawning in the fourhorn sculpin, Myoxocephalus quadricornis, from Alaska Summer spawning in the fourhorn sculpin, Myoxocephalus quadricornis, from Alaska

Histological ovarian analysis indicates summer spawning occurs in Myoxocephalus quadricornis (Fourhorn Sculpin) from Alaska. Previous studies have shown this species spawns during winter in the Baltic Sea; the data presented herein suggests that geographical variation may occur in the timing of spawning of this species.

Genetic variation in chinook, Oncorhynchus tshawytscha, and coho, O. Kisutch Genetic variation in chinook, Oncorhynchus tshawytscha, and coho, O. Kisutch

We used starch-gel electrophoresis to genetically characterize the populations of chinook salmon, Oncorhynchus tshawytscha, and coho salmon, O. kisutch, in the major drainages of the north coast of Washington (the Quillayute, Uoh, Queets, and Quinault Rivers). Of 55 loci examined for electrophoretically detectable variation. 6 were polymorphic (frequency of the common allele was less...

Family size and effective population size in a hatchery stock of coho salmon (Oncorhynchus kisutch) Family size and effective population size in a hatchery stock of coho salmon (Oncorhynchus kisutch)

Means and variances of family size measured in five year-classes of wire-tagged coho salmon (Oncorhynchus kisutch) were linearly related. Population effective size was calculated by using estimated means and variances of family size in a 25-yr data set. Although numbers of age 3 adults returning to the hatchery appeared to be large enough to avoid inbreeding problems (the 25-yr mean...

Sequential tests for infectious hematopoietic necrosis virus in individuals and populations of sockeye salmon Sequential tests for infectious hematopoietic necrosis virus in individuals and populations of sockeye salmon

The incidence and titer distribution of infectious hematopoietic necrosis virus in cavity fluid from spent female sockeye salmon (Oncorhynchus nerka) varied little when fish from a naturally spawning population were sampled three times on alternate days. However, when prespawning female sockeye salmon from a second population were individually tagged, penned, and sampled daily, the...
