Parasitism of dolfinfhishes, <i>Coryphaena hippurus</i> and <i>Coryphaena equiselis</i>, in the western Mediterranean (Balearic Islands) and central-eastern Atlantic (Canary Islands)
A total of 648 dolphinfishes were examined for internal and external parasites in western Mediterranean (Balearic Islands) and central-eastern Atlantic (Canary Islands) waters in order to make a comparative study between the two areas. The specimens studied from the Mediterranean Sea was Coryphaena hippurus, with 62 large individuals captured from May to September and 497 juveniles captured from August to December. The specimens studied from the central-eastern Atlantic were 39 adult C. hippurus and 49 adult Coryphaena equiselis. Parasites were found in 70% of the fish examined, and represented a total of nine endoparasitic taxa: six digeneans (Class Trematoda, Subclass Digenea; Dinurus tor…
Insular stock identification of <EM>Serranus atricauda</EM> (Pisces: Serranidae) through the presence of <EM>Ceratothoa steindachneri</EM> (Isopoda, Cymothoidae) and <EM>Pentacapsula cutanea</EM> (Myxozoa, Pentacapsulidae) in the Canary Islands
Ceratothoa steindachneri (Isopoda: Cymothoidae) and Pentacapsula cutanea (Myxozoa: Pentacapsulidae) parasites infecting the blacktail-comber ( Serranus atricauda ) were considered suitable as biological tags for stock identification around the islands of La Palma and Gran Canaria, in the Western and Eastern areas of the Canarian archipelago, respectively. The ecological parameters of both species differed significantly between the islands. While individuals caught off La Palma showed a high degree of infection by the isopod, a single infected fish was found off Gran Canaria. Also, the myxozoans showed a high level of infection on fish from Gran Canaria but it was reported on only a single s…
