Atlantic Salmon Salmo Salar

Differences in electropherograms produced by serum proteins and liver esterases were used to identify North American and European Atlantic salmon (Salmo salar) caught at sea. Division of salmon according to continent of origin was supported by mean river age, mean fork length, and abundance of the two parasites Anisakis simplex and Eubothrium crassum. Consistent differences in electrophoretic behaviour of serum proteins and liver esterases in salmon from the two continents support the suggestion that salmon from North America and Europe represent different subspecies.

Selective Forces

Existing analyses of spatial patterns of transferrin (Tf) allele frequency variation in anadromous Atlantic salmon (Salmo salar) from rivers in North America have not utilized all available data. Further analysis shows that a latitudinal dine in Tf-4 allele frequency previously reported is an artefact of a major regional difference between populations from Newfoundland/Labrador and those sampled elsewhere. Furthermore, the allele frequencies of populations outside Newfoundland/Labrador show a significant association with the proportion of spawning fish in the populations having spent only one winter at sea. Fequencies in Newfoundland/Labrador are collectively consistent with this relationship but by themselves show no similar correlation. These results, combined with previously reported differences between anadromous and nonanadromous fish, suggest that selective forces, which vary with life history pattern, may operate on the polymorphism.

ABSTRACTA 1-year study found seven infectious human adenovirus serotypes, including Ad3, Ad31, Ad46, Ad27, Ad22, Ad51, and clinical clone PB3, in wastewaters of two major cities in Canada. Comparative genomic analysis revealed the existence of the reportedly highly contagious Ad3a16/18 genotypes. This is the first report of Ad3a16/18 genotypes in North America.

Breeding Populations

There is good evidence to suggest that Atlantic salmon (Salmo salar) from North America and Europe form distinct breeding populations. However, it has been very difficult to discover a genetic marker that allows the continent of origin of an individual salmon to be determined unambiguously. Repetitive elements in the nuclear genome have provided population-specific markers in several species. Therefore, we examined the ribosomal RNA gene (rDNA) complex in Atlantic salmon by Southern blot analysis using a cloned repeating unit of the Drosophila melanogaster rDNA as a probe. A restriction fragment length polymorphism that could distinguish between salmon from Newfoundland and Scotland was detected using a combination of the restriction enzymes SacI and XbaI. The Newfoundland salmon had additional fragments of 3.6 kilobase pairs (kbp) and 2.6 kbp. Of 27 salmon from 10 populations in Europe, none possessed the 3.6- or the 2.6-kbp fragment whereas all 33 North American Atlantic salmon (from six populations) had the 2.6-kbp band and the majority showed the 3.6-kbp fragment. This preliminary survey strongly suggests that this genetic marker can be used to identify the continent of origin of individual Atlantic salmon.

Atlantic Salmon Salmo Salar

Pomphorhynchus laevis (Zoega) Müller, 1776, an acanthocephalan, occurred in 25.4% of 974 juvenile Atlantic salmon (Salmo salar) from 18 drainage systems in the British Isles and was absent in 1063 juvenile salmon from 36 systems in North America. Its incidence in Irish smolts was about 25 times that in Scotland, England, and Wales. A comparison of its distribution with that of potential intermediate hosts in the British Isles suggests that the amphipod Gammarus duebeni is the intermediate host in Ireland and Gammarus pulex pulex in Scotland, England, and Wales. Pomphorhynchus laevis seems to be useful for indicating the tributary of origin of salmon smolts in several Irish rivers. Its usefulness as a tag for Irish salmon on the high seas is not yet established.
