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.

Catch per unit effort standardization using spatio-temporal models for Australia’s Eastern Tuna and Billfish Fishery

ICES Journal of Marine Science, 2019
The majority of catch per unit effort (cpue) standardizations use generalized linear models (GLMs) or generalized additive models (GAMs). We develop geostatistical models that model catch locations as continuous Gaussian random fields (GRFs) and apply ...
