A microcytic anemia of juvenile chinook salmon resulting from diets deficient in vitamin E

Creator:

Whitmore, Cecil M. and Oregon. Fish Commission

Abstract:

An anemia of juvenile chinook salmon (Oncorhynchus tshawytscha) is described and stages of development separated by recognizable syndromes. A vitamin E-deficient diet of low rancidity produced a severe microcytic anemia with strong immature red cell response and granulocytosis occurring 2 to 4 weeks before a drop in hemoglobin and hematocrit...

Abstract:

Part I. To aid in the management of the Tillamook Bay commercial salmon fishery, a tagging program was conducted on the salmon and steelhead trout runs in 1953. General migration behavior, the minimum length of time the fish remained in the fishery, population sizes, and fishing mortalities were determined from...

Growth and mortality rates of the razor clam (Siliqua patula) on Clatsop beaches, Oregon

Creator:

Hirschhorn, George and Oregon. Fish Commission

Abstract:

Clatsop Beaches, characterized by flat beach-face slope (1:70) and small sandsize (0.2 mm.), have supported commercial and recreational fisheries for the razor clam (Siliqua patula) for many years. Tracing the linear growth of two year classes through more than one year following set led to a validation of the ring...

Abstract:

During a tagging operation conducted in 1951 on the Alsea River, 1,142 adult silver salmon were tagged with plastic Petersen-type tags and stainless steel jaw tags. An attempt was made to determine whether tagged fish released in different apparent conditions suffered differential mortalities. Under the hypothesis that the recovery of...

Abstract:

Ages were determined for 65 fish from the 1947 run and for 287 fish from the 1949 run. In 1947 the percentage composition by age was as follows: 32.3 percent 3-year-old fish, 66.2 percent 4-year-old fish, and 1.5 percent 5-year-old fish. An approximate 95 percent confidence interval for the true...

Some factors influencing the trends of salmon populations in Oregon

Creator:

McKernan, Donald L. (Donald Lynn), 1918-1979, Johnson, Donald R., Hodges, John I., and Oregon. Fish Commission

Abstract:

Three factors were found to be significantly correlated with the fluctuations and trends in silver salmon production in Oregon. Logging was found to adversely affect the runs of salmon in later years. Exceptional winter floods seem to produce poor resulting runs. Low summer water flows also appear to produce lower...

Abstract:

1. A rational conservation program for such migratory fishes as the salmon must be based on a knowledge of (a) whether or not the species consists of local, self-perpetuating populations and (b) the nature and extent of the oceanic migrations. 2. The conservation of a species that is broken up...
