A comparative analysis of European and American eel (<i>Anguilla anguilla</i> and <i>Anguilla rostrata</i>) genomic DNA: 5S rDNA polymorphism permits the distinction between the two populations

We studied possible molecular and cytological correlations between the European (Anguilla anguilla) and the American (Anguilla rostrata) eel, using either low molecular weight highly repetitive sequences isolated from genomic DNA of the two species, or highly conserved sequences, such as 45S or 5S rDNA, as probes. A clearcut difference was found only in filter hybridization experiments carried out using 5S rDNA as probe.Key words: fish, chromosomes, DNA, endonucleases, rDNA.

The age (otolith readings) and growth of American eels (Anguilla rostrata (LeSueur)) from fresh and brackish waters in Newfoundland were studied. The eels in Burnt Berry Brook grew faster than eels in the other areas. The growth of young eels in brackish water was slow. Although the growth of these eels increased in subsequent age groups, freshwater eels were consistently larger at each age.The silver eel migrates after spending 12 to 13 years in Newfoundland waters. The American eel in Newfoundland is generally larger than the European eel (Anguilla anguilla L.) at the onset of migration; however, its appearance and state of maturity parallel the condition described in the European eel.

Gonadal Condition

Fecundity of the American eel, Anguilla rostrata, was estimated from 21 specimens migrating from Chesapeake Bay during November 1970. The relationship between total length and fecundity is log y = −4.29514 + 3.74418 log x where y is fecundity and x is total length (mm) and between total weight and fecundity is log y = 3.22990 + 1.1157 log x where y is fecundity and x is total weight (g). Gonadal condition was described statistically and histologically. Specimens migrating from Chesapeake Bay are more sexually mature than either American eels migrating from Canadian waters or European eels, Anguilla anguilla, migrating from Europe. The significance of these findings with regard to Tucker's hypothesis of European eels being more sexually advanced at the onset of the spawning migration is discussed.
