ABSTRACT Eighteen nuclear-encoded microsatellites from a genomic DNA library of greater amberjack, Seriola dumerili, were isolated and characterized. The microsatellites include 13 perfect (five tetranucleotide and eight trinucleotide) and five imperfect (three tetranucleotide, one trinucleotide and one combination dinucleotide/trinucleotide) repeat motifs. The number of alleles at the 18 microsatellites among a sample of 29 fish ranged from two to 20; gene diversity (expected heterozygosity) ranged from 0.068 to 0.950, whereas observed heterozygosity ranged from 0.069 to 0.966. Following Bonferroni correction, genotypes at all 18 microsatellites fit expectations of Hardy-Weinberg equilibrium, and all pairwise comparisons of microsatellites did not deviate significantly from genotypic equilibrium. Greater amberjack support commercial and recreational fisheries along both the Atlantic and the Gulf coasts of the USA and represent a species with potential for worldwide aquaculture. The microsatellites developed will be useful for population genetic studies of 'wild' populations and breeding studies of domesticated populations.

    ABSTRACT: Thirty-one microsatellite markers that were previously isolated from and characterized in greater amberjacks Seriola dumerili were assayed for cross-species amplification in four other members of the carangid genus Seriola: the lesser amberjack S. fasciata, yellowtail jack S. lalandi, almaco jack S. rivoliana, and banded rudderfish S. zonata. The number of markers that consistently amplified and were polymorphic ranged from 16 in yellowtail jacks to 25 in lesser amberjacks. The microsatellites characterized in this study will be useful for a variety of applications, including stock structure assessments of wild fish and parentage assignments of farmed fish.Received February 7, 2012; accepted April 16, 2012

    ABSTRACT: The lipid and fatty acid compositions of the muscle and liver of two subtropical Seriola fish species, Seriola dumerili and Seriola rivoliana, were investigated. The lipid levels of cultured S. dumerili were significantly higher than were those of the wild ones. Triacylglycerols and phospholipids were the dominant lipids of both the cultured and wild. In both species, the major fatty acids in the muscle and liver triacylglycerols were 14:0 (cultured), 16:0, 18:0, 16:1n-7, 18:1n-7, 18:1n-9, 18:2n-6 (linoleic acid: LA, cultured), 20:5n-3, and 22:6n-3. In spite of similar levels of many of the fatty acids between cultured and wild triacylglycerols, the cultured samples had markedly higher levels of LA with trace levels of 20:4n-6 (arachidonic acid: ARA) and 22:5n-6, while the wild ones had very low 18:2n-6 levels with small levels of ARA and 22:5n-6. The ratio (R(LA/ARA)) of LA to ARA in the cultured samples was markedly higher than were those of the wild samples.

    ABSTRACT: Ensuring appropriate levels of genetic diversity in captive populations is essential to avoid inbreeding and loss of rare alleles by genetic drift. Pedigree reconstruction and parentage analysis in the absence of parental genotypes can be a challenging task that relies in the assignment of sibship relationships among the offspring. Here, we used eight highly variable microsatellite markers and three different assignment methods to reconstruct the most likely genotypes of a parental group of wild Seriola dumerili fish based on the genotypes of six cohorts of their offspring, to assess their relative contributions to the offspring. We found that a combination of the four most variable microsatellites was enough to identify the number of parents and their contribution to the offspring, suggesting that the variability of the markers can be more critical than the number of markers. Estimated effective population sizes were lower than the number of breeders and variable among years. The results suggest unequal parental contribution that should be accounted for breeding programs in the future.
