Mitochondrial DNA, 2011
DNA barcoding is a method promising fast and accurate identification of animal species based on the sequencing of the mitochondrial c oxidase subunit (COI) gene. In this study, we explore the prospects for DNA barcoding in one particular fish group, the billfishes (suborder Xiphioidei--swordfish, marlins, spearfishes, and sailfish).

Habitat and food partitioning of billfishes (Xiphioidei)
Journal of Fish Biology, 2010Species composition and food habits of four istiophorid billfishes were investigated and compared in three different tropical areas of the eastern North Pacific Ocean by longline operations from September to November 2004. Sailfish Istiophorus platypterus, shortbill spearfish Tetrapturus angustirostris and blue marlin Makaira nigricans had specific ...

An Ecotourism Perspective on Billfish Fisheries
Journal of Sustainable Tourism, 1998Tourism is a major source of earnings, supplemental to and possibly replacing those of agriculture and extractive industries in many regions of the world. Fish stocks and the recreational fishing opportunities they afford are one of many natural resource based attractions that lure tourists to various destinations.

Population structure of istiophorid billfishes
Fisheries Research, 2015Abstract The phylogeny of istiophorid billfishes was recently revised based on analyses of nuclear and mitochondrial DNA loci, and a variety of molecular genetic characters has been used to investigate population structuring within several species of billfish.

Postrelease mortality in istiophorid billfish
Canadian Journal of Fisheries and Aquatic Sciences, 2015Meta-analysis (inverse-variance, random-effects model) involving 46 studies was used to estimate the effect size of postrelease mortality (Fr) in six istiophorid billfish species (black marlin (Istiompax indica), blue marlin (Makaira nigricans), longbill spearfish (Tetrapturus pfluegeri), sailfish (Istiophorus platypterus), striped marlin (Kajikia ...

Theoretical calculations of bite force in billfishes
Journal of Zoology, 2017AbstractBite force is one of the most utilized performance measures due to its association with feeding and consequently fitness. Due to their large size and the concomitant increase in the adductor muscles it is expected that apex predators may rely on high biting performance allowing for increased dietary breadth.

Spatial surplus production modeling of Atlantic tunas and billfish
Ecological Applications, 2011We formulate and simulation-test a spatial surplus production model that provides a basis with which to undertake multispecies, multi-area, stock assessment. Movement between areas is parameterized using a simple gravity model that includes a "residency" parameter that determines the degree of stock mixing among areas.

ICCAT stock assessments of Atlantic billfish
Marine and Freshwater Research, 2003This paper presents a historical overview of the assessments of the Atlantic stocks of blue marlin ( Makaira nigricans ), white marlin ( Tetrapturus albidus ) and sailfish ( Istiophorus platypterus ) that have been conducted by the International Commission for the Conservation of Atlantic Tunas between 1977 and 2000.
