“…In the 1960s genetic analysis based on blood groups (Møller, 1966) and blood proteins (Frydenberg et al, 1965;Møller, 1968) supported the view that cod could be divided into migratory Arctic cod, and more stationary coastal cod. However, Frydenberg et al (1969) argued that the variation in frequency of one of the blood proteins (haemoglobin-Hb I) along the Norwegian coast could also be explained by selection from different environmental conditions.…”

Atlantic cod (Gadus morhua) encompasses many different populations or stocks, which in part are managed separately. In the northeast Atlantic cod is divided into two main management units; northeast Arctic cod and coastal cod. These two groups have traditionally been separated by otolith classification. In this study, the power of different classes of genetic markers in separating the two cod groups was investigated. The variation in thirteen genetic markers, including allozymes, haemoglobin, the scDNA locus Pantophysin (Pan I) and a number of microsatellites was investigated, and mixed stock analysis and individual assignment tests were performed on samples comprising a mixture of individuals of putative coastal and oceanic type cod. The genetic analyses showed a large genetic differentiation between outer stations and stations located closer to the mainland shore. Mixed stock analysis and individual assignment tests used for estimation of stock proportions gave results similar to those obtained by otolith classification.

“…Considerable effort has been made to measure the extent to which these stocks represent biological populations and/or genetic demes; the answer remains equivocal. Early studies of hemoglobin protein markers found significant frequency differences among geographic locations (Cross & Payne, 1978; Frydenberg, Møller, Nævdal, & Sick, 1965; Gjøsæter, Jørstad, Nævdal, & Thorkildsen, 1992; Møller, 1968; Sick, 1965a,b), although selection and temperature differences have since explained many of these results (Jamieson & Birley, 1989; Mork & Sundnes, 1985). Trans‐Atlantic differences are evident in protein loci (Jamieson, 1967; Mork, Ryman, Ståhl, Utter, & Sundnes, 1985), mitochondrial cytochrome b (Carr & Marshall, 1991a; Sigurgíslason & Árnason, 2003), and nuclear DNA markers (Pogson, Mesa, & Boutilier, 1995), although results at local scales remain ambiguous.…”

The historical phylogeography, biogeography, and ecology of Atlantic cod (Gadus morhua) have been impacted by cyclic Pleistocene glaciations, where drops in sea temperatures led to sequestering of water in ice sheets, emergence of continental shelves, and changes to ocean currents. High‐resolution, whole‐genome mitogenomic phylogeography can help to elucidate this history. We identified eight major haplogroups among 153 fish from 14 populations by Bayesian, parsimony, and distance methods, including one that extends the species coalescent back to ca. 330 kya. Fish from the Barents and Baltic Seas tend to occur in basal haplogroups versus more recent distribution of fish in the Northwest Atlantic. There was significant differentiation in the majority of trans‐Atlantic comparisons (ΦST = .029–.180), but little or none in pairwise comparisons within the Northwest Atlantic of individual populations (ΦST = .000–.060) or defined management stocks (ΦST = .000–.023). Monte Carlo randomization tests of population phylogeography showed significantly nonrandom trans‐Atlantic phylogeography versus absence of such structure within various partitions of trans‐Laurentian, Northern cod (NAFO 2J3KL) and other management stocks, and Flemish Cap populations. A landlocked meromictic fjord on Baffin Island comprised multiple identical or near‐identical mitogenomes in two major polyphyletic clades, and was significantly differentiated from all other populations (ΦST = .153–.340). The phylogeography supports a hypothesis of an eastern origin of genetic diversity ca. 200–250 kya, rapid expansion of a western superhaplogroup comprising four haplogroups ca. 150 kya, and recent postglacial founder populations.

“…In sheep, with Hb AB and Hb BB genotypes had been observed to have an effect on their performance (Dally et al, 1980;Arora, 1984;Dratch et al, 1986). Sick (1965) reported haemoglobin polymorphism in Cod and found that the frequencies of the Hb I' allele range from 55 to 72 %. Braman et al (1980) investigated haemoglobin polymorphism in a population of adult Cutthroat trout (Salmo clarkii) by employing starch gel electrophoresis and reported 12 haemoglobin components in the species.…”

Haemoglobin polymorphism, haemoglobin concentration, blood group and genotypes of wild and cultured Clarias gariepinus were investigated. Blood samples of Clarias gariepinus collected from Lake Alau (wild) and Dalori fish farm (cultured) were subjected to cellulose acetate electrophoresis to reveal the activities of hemoglobin (Hb). The result shows that both wild and cultured C. gariepinus had AA, BB and CC genotypes in the males and females. However, BD genotype was observed only in the female wild C. gariepinus. The percentage AA and BB genotypes of wild male C. gariepinus was 6.6% each. Wild females had AA, BB, CC and BD genotype with frequencies of 26.6, 33.3, 20 and 6.6% respectively. Cultured male C. gariepinus had AA, BB and CC with frequencies of 13.3, 26.6 and 6.6%, respectively, while the female C. gariepinus had AA, BB and CC with frequencies of 20, 13.3 and 20% respectively. Wild C. gariepinus had the highest (10.36 g/dl) haemoglobin
