Chromosomal evolution in large pelagic oceanic apex predators, the barracudas (Sphyraenidae, Percomorpha)

Sphyraena (barracudas) represents the only genus of the Sphyraenidae family and includes 27 species distributed into the tropical and subtropical oceanic regions. These pelagic predators can reach large sizes and, thus, attracting significant interest from commercial and sport fishing. Evolutionary data for this fish group, as well its chromosomal patterns, are very.. Read More»

Performance of human immunostimulating agents in the improvement of fish cytogenetic preparations

    W.F. Molina, D.E.O. Alves, W.C. Araújo, P.A. Martinez, M.F.M. Silva and G.W.W.F. Costa

Inoculation with bacterial or fungal antigens that stimulate cell proliferation has been widely used to obtain metaphases for cytogenetic studies of fish. We evaluated the potential of new pharmaceutical compounds as mitogenic agents in fish, testing the efficacy of Aminovac® (mixed antigens and epsilon-acetamidocaproic acid), Broncho-Vaxom® (bacterial lysat..

Karyoevolution of the toadfish Thalassophryne nattereri (Batrachoidiformes: Batrachoididae)

    G.W.W.F. Costa and W.F. Molina

The Batrachoididae includes some venomous brackish and marine fish found in the Atlantic, Indian and Pacific oceans. This family is composed of 69 species, distributed among 19 genera. Species of the genus Thalassophryne have been reported along the coast of Rio Grande do Norte (Brazil); T. nattereri has been responsible for a large number of human injuries. Little is known about the cytogeneti.. Read More»

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

    R.X. Soares, L.A.C. Bertollo, M.B. Cioffi, G.W.W.F. Costa and W. F. Molina

olphinfishes (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 ..
