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

Reiteration Frequency of the Protamine Genes in Rainbow Trout (SaZmo 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 ...

Observations on Hepatic Cell Hyperplasia, Adenoma, and Hepatoma of Rainbow Trout (salmo Gairdnerii).

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 th...
