Postrelease mortality in istiophorid billfish

Canadian Journal of Fisheries and Aquatic Sciences, 2015
Meta-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 ...

An Ecotourism Perspective on Billfish Fisheries

Journal of Sustainable Tourism, 1998
Tourism 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.

Habitat and food partitioning of billfishes (Xiphioidei)

Journal of Fish Biology, 2010
Species 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 ...

Can circle hook use benefit billfishes?

Fish and Fisheries, 2009
AbstractWe performed a quantitative review to evaluate circle hook use in recreational and commercial hook‐and‐line fisheries that interact with billfishes (Family: Istiophoridae). Specifically, we scrutinized the findings of 11 recent empirical studies that reported, on a species‐specific basis, side‐by‐side measures of circle vs.

ICCAT stock assessments of Atlantic billfish

Marine and Freshwater Research, 2003
This 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.

Theoretical calculations of bite force in billfishes

Journal of Zoology, 2017
AbstractBite 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.

Mercury contents in commercial Billfish species of the Western Central Atlantic: Assessing the potential risks to human health of Billfish consumption

Food Control, 2020
Abstract Purpose of the present study was to evaluate the total Hg (THg) level in Billfish caught in the Western Central Atlantic and to assess the potential health consequences due to consumption for people living in Grenada (GR) and in the Dominican Republic (DR). Consumption data were collected through the administration of an online questionnaire

Spatial surplus production modeling of Atlantic tunas and billfish

Ecological Applications, 2011
We 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.

Social and economic perspective on recreational billfish fisheries

Marine and Freshwater Research, 2003
At the Second International Billfish Symposium in Kona, it was reported that little was known about the social and economic aspects of recreational billfish fisheries. There was plenty of background, some good questions, but few answers. There had been little history of social science involvement in fisheries management at the time and even less in ...

Historical perspective of global billfish stock assessment

Marine and Freshwater Research, 2003
In spite of the substantial increase in information on billfish over the last decade, especially in the landing and catch per unit effort data, statistics for some of the commercial and recreational fisheries, basic biological information on billfish such as on growth, maturation, catch at age, and sex ratio by size, is still insufficient for the ...
