“…For A. anguilla, protein electrophoresis and sequencing of the mitochondrial DNA (mtDNA) control region support the hypothesis that eels from European and North African rivers belong to a panmictic population (De Ligny & Pantelouris 1973, Lintas et al 1998, Avise 2003. Similar conclusions were reached for A. rostrata and A. japonica (Avise et al 1986, Sang et al 1994, Ishikawa et al 2001.…”

The catadromous Japanese eel has an unusual life history. Controversy remains, however, as to whether its population structure is characterized by panmixia or genetic differentiation. Migration patterns are considered an important factor in determining a species' population structure. Eight polymorphic microsatellite loci were used as genetic markers through which we were able to reject the null hypothesis of panmixia. Slight genetic differentiation between these populations was determined by Wright's and Slatkin's fixation indices, F ST and R ST statistics adjusted using Bonferroni's correction. Although isolation-by-distance is often observed in marine species, the present result is thought to follow the member-vagrant migratory hypothesis. The metapopulation model fits the elver recruitment strategy according to results of the high probability of assignment test. The UPGMA tree showed the Japanese eel populations as being divided into 2 groups: a low-latitude group (Shantou in South China, and Tanshui and Fangliao in Taiwan) and a high-latitude group (Mikawa Bay in Japan, Daecheon-myon in Korea, and the Yalu River and Hangzhou in Northeast China). Temporal genetic variations indicate that most progeny return to similar habitats where their ancestors formerly resided. There was a high correlation (AMOVA; p < 0.05) when the Japanese eel was divided into the 2 management units (high-and low-latitude groups). These units will be useful when applied to fisheries conservation and management in the northwestern Pacific Ocean.

“…Sick et al (1967) demonstrated hemoglobin polymorphism in the American eel, While the European eel is monomorphic; Jamieson & Turner (1980) reported differences between the two Atlantic populations in muscle proteins. A significant contribution at the genetic level was the elucidation of marked differences in allele frequencies of the MDH-2 locus (malate dehydrogenase) between samples of American and European eels observed by De Ligny & Pantelouris (1973) and confirmed by Williams et al (1973) and Rodin5 & Comparini (1978a). This biochemical genetic difference was, however, observed at advanced developmental stages; it could result from differential selection, depending on different environmental conditions met with by leptocephali during their migration to different continental waters.…”

Marked differences between continental samples of American and European eels have been detected electrophoretically in allele frequencies at the MDH-2 locus. Starch gel electrophoresis carried out on board F. R. V. "Anton Dohrn" during the eel expedition to the Sargasso Sea in 1979 revealed a similar clear-cut genetic difference in a sample of 0-group Anffuilla leptocephali, thus confirming the classical theory of Schmidt (1932). The MDH-2 genotypes provide an additional diagnostic character for the distinction between young A. anguilla and A. rostrata leptocephali. Species identification by biochemical genetic characters did not correspond with that by meristic characters (rnyomere numbers) in ca. 13 % of the specimens studied; this discrepancy mainly concerns leptocephali of the A. anguilla genotype. The results obtained are critically discussed.

“…This theory, which emerged with the discovery of the A. anguilla spawning ground in the Sargasso Sea in 1920 (Schmidt 1925), gave rise to many studies aimed at seeking genetic structure in a seemingly panmictic species. At first, neither nuclear allozymic markers nor mitochondrial DNA sequences had allowed the identification of distinct genetic pools in samples from different locations of the European eel's distribution area (De Ligny et al 1973, Comparini et al 1977, Lintas et al 1998). More recently, 2 studies using microsatellite nuclear markers reported genetic variation between eel samples of different continental locations (Daemen et al 2001, Wirth & Bernatchez 2001, and a positive correlation between genetic and geographic distances was independently shown with microsatellite and allozymic markers (Wirth & Bernatchez 2001, Maes & Volckaert 2002.…”
