“…The level of biochemical polymorphism typical of some populations remains almost unchanged throughout many successive generations. Thus, in sockeye salmon from Dalneye and Azabachye lakes in Kamchatka, allelic frequencies of LDH-BI* and PGM-3" have hardly changed between 1972 and 1989 (Altukhov, 1989;Kirpichnikov et al, 1990). In pink salmon [Oncorhynchus gorbuscha (Walbaum)] from Sakhalin island we see the constancy of allelic frequency of G3PDH*, PGDH* and PGM* between 1974 and 1985 (Table I).…”

Functional differences between allozymes were obtained in many other enzyme systems, in particular, they were detected for allelic variants of MDH and EST (Koehn, 1969(Koehn, , 1970Philipp et ul., 1983), for allozymes of GPI and PGDH (Ropson & Powers, 1989;Van Beneden & Powers, 1989), and for the regulatory gene of PGM (e.g.…”

The balanced selective nature of protein polymorphism in fishes is reviewed, noting its diversity and association with molecular structure and size. The functional and kinetic differences between allelic variants are discussed for the few species within which they have been studied, and related to population size, habitat and clinal variation. Heterosis is discussed in relation to heterozygote excess and deficit in natural and in reared populations, and the nature of heterozygote advantage considered. Natural selection of protein loci is evidenced in changes of allele frequency with age, with experience of environmental extremes (heated effluents), and in culture. Finally, it is argued that protein polymorphism has a primarily adaptive nature, arising through selection pressures rather than through genetic drift.

“…Often these morphs appear to be ecological life-history phenotypes rather than genetically distinct populations (Ricker 1938(Ricker , 1940Smirnov 1959;Sage and Selander 1975;Turner and Grosse 1980;Krogius 1981;Jonsson and Hindar 1982;Nordeng 1983;Hindar et al 19861991;Meyer 1987). However, some sympatric morphs are genetically distinct (Neave 1944;Lindsey 1963;Allendorf et al 1976;Kirkpatrick and Selan-der 1979;Ryman et al 1979;Ferguson and Mason 1981;Verspoor and Cole 1989;Kirpichnikov et al 1990;Bodaly et al 1992;Sch1iewen et al 1994) and probably exist as reproductively isolated populations like sockeye and kokanee. The sympatric distribution of these distinct morphs has sometimes been attributed to successive waves of colonization by populations which had diverged in allopatry, typically in different refugia during glaciation (Svardson 1970;Behnke 1972;Bernatchez and Dodson 1990).…”

Anadromous and nonanadromous morphs of the Pacific salmon Oncorhynchus nerka spawn in close physical proximity in tributaries to Takla Lake, British Columbia, yet differ in morphology, gill raker number, allozyme allele frequencies, and reproductive traits. Both morphs are semelparous typically maturing at age four, the anadromous morph (sockeye) at fork lengths of 38-65 cm and the nonanadromous morph (kokanee) at 17-22 cm. When reared together, pure and hybrid morphs also exhibited different growth rates and maturity schedules. Collectively, these large differences between the morphs confirm that sockeye and kokanee exist as reproductively isolated populations. Average gene flow (m) was estimated to be 0.1-0.8% between morphs, 1.7-3.7% among tributaries for kokanee, and 0.3-5.6% among tributaries for sockeye. We conclude that divergence has occurred in sympatry and examine potential isolating mechanisms.

“…In particular, dwarf males maturing in freshwater were found to differ from other individuals of the same population by an increased heterozygosity in protein-coding loci in sockeye salmon (Kirpichnikov et al, 1990), brown trout (Makhrov et al, 1997) and Atlantic salmon . For the latter species, there is also data available on the correlation between dwarfism and the presence of the *0Q allele in the regulatory locus PGM-1r* (Pollard et al, 1994).…”
