“…Enzymatic analyses of these two species reveal exclusive alleles with marked differentiation (Pujolar and Pla, 2002). Recent investigations using mitochondrial DNA identified three phylogroups of C. hippurus in the Eastern Atlantic, Indo-Pacific, and Mediterranean Sea (Diaz-Jaimes et al, 2010).…”

Chromosomal distribution of two multigene families and the unusual occurrence of an X1X1X2X2/X1X2Y sex chromosome system in the dolphinfish (Coryphaenidae): An evolutionary perspective

ABSTRACT. Dolphinfishes (Coryphaenidae) are pelagic predators distributed throughout all tropical and subtropical oceans and are very important for commercial, traditional, and sport fishing. This small family contains the Coryphaena hippurus and Coryphaena equiselis species whose chromosomal aspects remain unknown, despite recent advances in cytogenetic data assimilation for Perciformes. In this study, both species were cytogenetically analyzed using different staining techniques (C-, Ag-, and CMA 3 banding) and fluorescence in situ hybridization, to detect 18S rDNA and 5S rDNA. C. hippurus females exhibit 2n = 48 chromosomes, with 2m+4sm+42a (NF = 54). In C. equiselis, where both sexes could be analyzed, females displayed Sex chromosomes in the dolphinfish 2n = 48 chromosomes (2m+6sm+40a) and males exhibited 2n = 47 chromosomes (3m+6sm+38a) (NF = 56), indicating the presence of X 1 X 1 X 2 X 2 /X 1 X 2 Y multiple sex chromosomes. Sex-chromosome systems are rare in Perciformes, with this study demonstrating the first occurrence in a marine pelagic species. It remains unknown as to whether this system extends to other populations; however, these data are important with respect to evolutionary, phylogenetic, and speciation issues, as well as for elucidating the genesis of this unique sex system.

“…At the largest spatial scale, genetic differentiation was reported between eastern Atlantic and western Pacific dolphinfish populations, presumably because of dispersal limitations and vicariance between basins (Díaz-Jaimes et al, 2010). At the basin-wide scale, Díaz-Jaimes et al (2010), using mtDNA nicotinamide adenine dinucleotide (NADH) dehydrogenase subunit 1 (ND1) sequences, observed genetic divergence between the western (Caribbean Sea) and eastern Atlantic (Senegal).…”

“…In the state of Rio de Janeiro (RJ), for example, fishing for this species reached 1,681 tons in 2012, representing 2% of the total marine fishery production in the state for that year (Fundação Instituto da Pesca do Estado do Rio de Janeiro; FIPERJ, 2013). Due to its good swimming capabilities, C. hippurus can be found in the epipelagic zone of tropical and subtropical waters (Gibbs Jr., Collette, 1959), and due to its very active migratory habits, the stocks for this species are expected to be very large (Díaz-Jaimes et al, 2010).…”

Taxonomic status of two morphotypes of Coryphaena hippurus (Perciformes: Coryphaenidae)

et al. 2017

Two Coryphaena hippurus morphotypes (dourado and palombeta) are found along the Brazilian coast and are considered by Rio de Janeiro's fisherman and fishmongers as two different species. Furthermore, these morphotypes are commercialized under different values and suffer different fishing pressure. Therefore, a definition of their taxonomic status is an important economic and biological matter. In order to investigate this problem, allozyme electrophoresis method was undertaken for seventeen loci on 117 individuals of C. hippurus sampled at Cabo Frio/RJ (Brazil). The data indicate homogeneity between the morphotypes gene pools. Nevertheless, differences were found for genetic variation among dourado and palombeta, especially due to alcohol dehydrogenase locus. Natural selection hypothesis is discussed in explaining these findings.Keywords: Alcohol dehydrogenase, Allozyme electrophoresis, Biochemical systematics, Fishery resources, Genetic variation. Dois morfotipos deCoryphaena hippurus (dourado e palombeta) encontrados ao longo da costa brasileira são considerados espécies diferentes por pescadores e mercadores das regiões de desembarque do estado do Rio de Janeiro. Além disso, esses morfotipos são comercializados por valores diferentes e sofrem diferentes pressões de pesca. Desta forma, a definição do status taxonômico desses morfotipos é importante, tanto em termos econômicos quanto biológicos. A fim de investigar esse problema foi utilizado o método de eletroforese de aloenzimas com a amostragem de dezessete loci para 117 indivíduos dos dois morfotipos de C. hippurus obtidos em desembarques pesqueiros na região de Cabo Frio/RJ (Brasil). Os dados indicaram uma homogeneidade entre os conjuntos gênicos dos morfotipos. A despeito disso, diferenças entre os conjuntos gênicos de dourado e palombeta foram encontradas, devido, especialmente, ao locus álcool desidrogenase. A hipótese de seleção natural é discutida como possível explicação para esses resultados.
