Studies on hemoglobins of some gadoid fishes
MetadataShow full item record
1. Hemoglobin of tusk, forked hake, ling, blue ling, hake, pout, Norway pout, pollach, coalfish, haddock and blue whiting were studied by agargel electrophoresis. 2. Both inter- and intraspecific variations in hemoglobin patterns occurred. 3. Intraspecific variations were found in tusk, ling, blue ling, pollack, coalfish (only one specimen differed from the "normal" pattern), haddock and blue whiting. 4. A hypothesis of genetical control involving two allelomorphic genes is proposed to explain the variations within each species. The population data coincided with this hypothesis. 5. No indication of ontogenetic variation of hemoglobin patterns have been found. 6. Frequncy variations of the hemoglobin types in ling indicate segregetion in the population structure.
