Striped marlin are found in more temperate waters than others istiophorids
, with strong preferences for waters 20-25[degrees]C (Ueyanagi, 1965; Domeier, 2006).
The specimen is compared with extant and fossil istiophorids
, and 19 of its 20 morphological variables are within the range of values observed for extant M.
Atlantic management area, commercial harvesting of istiophorid
billfish species has been prohibited since 1988.
Of the tunas and istiophorids
, the striped marlin (Tetrapturus audax) (n = 301; 8.0%) and the yellowfin tuna (Thunnus albacares) (n = 185; 4.9%) were the most important species.
Habitat preferences of istiophorid
billfishes in the western north Atlantic: applicability of archival tag data to habitat-based stock assessment methodologies.
nigricans, as well as some less diagnostic istiophorid
remains, in the middle facies of the Trinidad Formation (late Miocene to late Pliocene) in the San Jose del Cabo Basin, Baja California Sur, Mexico, offers the first opportunity to examine billfish specimens from fossil deposits located between southern California and Panama and to discuss the paleoecology of the Trinidad Formation based on the habitat preference of a still extant bony fish.
Similar findings have been reported for istiophorid
billfish, which showed significantly lower at-vessel mortality (Diaz, 2008; Serafy et al., 2008) and postrelease mortality (Horodysky and Graves, 2005) with the use of circle hooks over J-hooks.
billfishes in the Atlantic Ocean experience considerable fishing pressure and most stocks are overfished.
A percentage of istiophorid
larvae (22.2%) were identified to the species level by following the protocol of Bangma (2006).
This study has shown that surface mucous contains sufficient quantities of genomic DNA to carry out RAPD analyses of istiophorid
billfishes and swordfish, as well as sequencing applications of istiophorid
White marlin (Tetrapturus albidus Poey 1860) is an istiophorid
billfish species widely distributed in tropical and temperate waters throughout the Atlantic Ocean, including the Caribbean Sea.
Abstract--The identification of larval istiophorid
billfishes from the western North Atlantic Ocean has long been problematic.
Neuston tows (n=23) yielded 18 istiophorid
larvae: eight were white marlin, four were blue marlin, and six could not be identified to species.
Little acoustic tracking has been conducted on white marlin (Skomal and Chase, 2002; n=2 tracks), but similar work on other istiophorid
species indicates relatively high postrelease survival for periods ranging from a few hours to a few days for fish released from recreational fisheries (e.g., sailfish: Jolley and Irby, 1979; blue marlin: Holland et al., 1990; Block et al., 1992; black marlin: Pepperell and Davis, 1999).
Larvae undergo a stark change in physical appearance between ~8 and 13 mm preserved standard length (PSL), from a typical scombroid larval form to a juvenile istiophorid
one (Collette et al., 1984).
