EXTRACT (SEE PDF FOR FULL ABSTRACT): The seasonal cycles of coastal wind stress, adjusted sea level height (ASL), shelf currents and water temperatures off the west coast of North America (35°N to 48°N) were estimated by fitting annual and semiannual harmonics to data from 1981-1983. Longer records of monthly ASL indicate that these two harmonics adequately represent the long-term monthly average seasonal cycle, and that the current measurement period is long enough to define the seasonal cycles, with relatively small errors in magnitude and phase.

To detect rainbow trout hatcheries for infectious hematopoietic necrosis virus, samples of kidney, liver, spleen, muscle, intestine, heart and gills of trout larvae were obtained from a number of trout hatcheries from different provinces. Also tissue samples were obtained for molecular works using RT- PCR procedure. Tissue samples were processed using standard histotechnique and the obtained sections were stained using immunohistochemical procedure. From 100 examined samples 35 were positive for IHN by immunohistochemical test. Also, from 100 samples examined, 43 were positive in RT- PCR studies. The obtained results show that some rainbow trout hatcheries are contaminated in different regions of country. Therefore, a definition of prevention and eradication criteria are now critical to protect the unaffected areas within the country.
