|dc.description.abstract||1. Hemoglobins and serum proteins of herring have been analyzed by
agar gel electrophoresis (hemoglobins) and combined starch and agar
gel electrophoresis (serum proteins). The material comprises twelve
samples from the Norwegian coast and the North Sea and one sample
from the east coast of Canada, a total of 1,546 specimens.
2. The results of the hemoglobin analyses were in general agreement with
the ontogenetic variation described by WILKINS and ILES (1966).
3. Intraspecific variation was noted in the transferrin components. Three
common transferrin types were found and assumed to be controlled by
two allelomorphic genes. No relation to age or length was found.
Presence of additional weak components complicated the type determination.
Hemoglobins in the sera as well as prolonged storage
made the type determination unreliable.
4. Observed albumin variations could be explained assuming control
by two alleles, while observed variations in other serum protein groups
were too weak or too diffuse for classification. A broad and diffuse
band was found on the electrophoretograms from ripe females.
5. Considerable variations in the frequencies of the genes supposed to
control the transferrin types were observed among samples. The type
determinations were in some specimens complicated, but the observed
variation were greater than what could be explained by incorrect
type determination or sampling error. The variation therefore probably
represent real differences among population units.||
