been reported in fish, all of them in trout (924,34, 47). In 1955 a high incidence of hepatic tumors was found in rainbow trout in Italian hatcheries (9). Interest in these neoplasms was renewed recently when hepatic tumors were discovered in large numbers of hatchery-reared rainbow trout in the United States (928,35, 592,61, 64), Italy (920), and France (3, 30). The main varieties of tumors that occur in man and other warm-blooded vertebrates have also been observed in fish but have been largely neg lected by oncologists (31, 56). The apparent recent increase in the incidence of hepatic tumors in trout

Changes in Plasma 17-hydroxycorticosteroids Accompanying Sexual Maturation and Spawning of the Pacific Salmon (oncorhynchus Tschawytscha) and Rainbow Trout (salmo Gairdnerii).

In the course of an investigation into the nature of the post-spawning death of the Pacific salmon,1-3 marked hyperplasia of the adrenal cortical tissue was found to be present constantly in the sexually mature fish of both sexes.4 5 Beginning hyperplasia was observed in immature salmon taken on their spawning migration several months before they were due to spawn. This change became more prono...

An experimental study to evaluate pathogenicity of Yersinia ruckeri isolated from rainbow trout (Oncorhynchus mykiss) in Caspian trout (Salmo caspius)

The main objective of this study was to evaluate the pathogenicity of isolated   Yersinia ruckeri  from Caspian trout. Y. ruckeri specimens were isolated from infected rainbow trout farms located in north of Iran. The identification was confirmed by biochemical tests and 16s rRNA gene sequencing. The pathogenicity test was carried out to determine the virulence of the Y. ruckeri by IP injection...

Reiteration frequency of the protamine genes in rainbow trout (Salmo gairdnerii).

Protamine mRNA was isolated in a very pure form from trout testis and used as a template for the synthesis of a complementary DNA of high specific activity. The cDNA represented a full copy of the mRNA template and was used in hybridization reactions with purified trout DNA to determine the number of genes for protamines in trout testis. Our results indicate that there are less than four genes ...
