“…sturgeons (Brown et al, 1988) while species with low longevity also have low levels of mitochondrial DNA variation, e.g. albacore tuna (Graves and Dizon, 1989). Further research will be necessary to determine the age dependency of mitochondrial DNA before its role in any kind of population analysis can be determined (Gauldie, 1991).…”

Preliminary genetic studies have given evidence for the existence of three distinct groups, characterized using several molecular genetic markers. The biological or ecological significance of these between-group differences has, however, not been evaluated. In the present paper, we review the life cycle of S. mentella in this area, based on published data. Spawning of S. mentella in the Irminger Sea takes place in a single area above Reykjanes Ridge. The larvae drift towards East Greenland from where they are carried to West Greenland (NAFO Subareas 0+1). Later they return to East Greenland where the main nursery area has been identified. There is evidence for a migration of juvenile fish from the nursery area into the open Irminger Sea, where many different cohorts spawn. We also compare these ecological data with the genetic results and we conclude that the observed genetic differences can be derived from possible genetic drift, selection or mostly from temporal variation (age dependency) which has also been reported for other species with as high longevity as S. mentella. We conclude that S. mentella in the Irminger Sea and adjacent waters comprises one single population.

“…A deeper divergence among mtDNA lineages has been observed for blue marlin and sailfish (Graves and McDowell, 2003), questioning the taxonomic status of these evolutionary units. In contrast, the Atlantic and Indo-Pacific populations of tuna species such as yellowfin and skipjack were found to be genetically indistinguishable, based on a variety of molecular markers (Graves et al, 1984;Graves and Dizon, 1989;Scoles and Graves, 1993). However, Ely et al (2005) reported small differences using RFLP analysis of the mtDNA ATCO gene region for yellowfin tuna, although not for skipjack.…”

“…The genetic similarity found in albacore Thunnus alalunga and skipjack tuna Katsuwonus pelamis between the Pacific and Atlantic Oceans by Graves et al (1984) and Graves & Dizon (1989) could be explained by their high vagility. This high migratory capacity in tunas has been demonstrated by tagging studies (Joseph et al 1988).…”

Restriction fragment length polymorphism (RFLP) analysis of mitochondrial DNA (mtDNA) was used to investigate population structure of the North Pacific swordfish X i p h~a s gladius. Sam:ples of X. gladius from the western (n = 47), central (n = 42), and eastern (n = 59) Pacific were examined for mtDNA variation using 17 six-base pair restriction endonucleases. A total of 27 composite mtDNA genotypes were revealed, and 50 % or more of individuals from each area shared the most common composite genotype. Pooled nucleon divers~ty and nucleotide diversity were 0.637 and 0.0019, respectively, and the mean nucleotide sequence divergence among genotypes was 0.88% (rank 0.11 to 2.80 %). Both nucleotide differences between populations and Gst analysis revealed low values. No significant geographic variation in genotypic frequencies was revealed by G-test and Monte Carlo randomization analysis with 1000 replicates. This suggests that there is sufficient gene flow across the North Pacific to prevent genetic differentiation, and is consistent with the interpretation that North Pacific swordfish represent a single genetic stock.
