Positive Selection in NADH Dehydrogenase 2 (ND2) Gene in Two Billfishes Xiphias gladius, L. 1758 and Istiophorus platypterus

open access: yesDiversity
The assumption of neutrality for mitochondrial DNA has been widely questioned due to the functional importance of the encoded proteins. Mitochondrial genes involved in the oxidative phosphorylation (OXPHOS) pathway can be subjected to selection due to ...

Distribution and habitat associations of billfish and swordfish larvae across mesoscale features in the Gulf of Mexico.

open access: yesPLoS ONE, 2012
Ichthyoplankton surveys were conducted in surface waters of the northern Gulf of Mexico (NGoM) over a three-year period (2006-2008) to determine the relative value of this region as early life habitat of sailfish (Istiophorus platypterus), blue marlin ...

Growth Autocorrelation in Atlantic Bluefin Tuna Thunnus thynnus Larvae in the Northwest Mediterranean and the Gulf of Mexico

open access: yesFisheries Oceanography, Volume 35, Issue 2, Page 297-305, March 2026.
ABSTRACT Growth and survival rates during the early life stages are key vital parameters driving population dynamics of fish. Growth rates generally present a pattern of autocorrelation. Growth autocorrelation is stronger when faster and slower growing individuals continue to grow faster and slower.

Temporal Trends in Relative Abundance of Billfish and Other Large Pelagic Fish in Recreational Fisheries of Costa Rica

open access: yesFisheries Management and Ecology, Volume 32, Issue 6, Page 499-515, December 2025.
ABSTRACT Fishing tourism of sailfish and accompanying species represents a significant source of income for Costa Rica. However, little information is available regarding trends in the availability of these species to recreational fleets. We estimated temporal trends in catch per unit effort (CPUE) for sailfish, marlins, yellowfin tuna, and mahi mahi ...

Direct effects and prey‐mediated effects of global change in projections of early life stages of pelagic predators

open access: yesEcography, Volume 2025, Issue 11, November 2025.
Global change will impact the distribution and abundance of predators through a combination of abiotic variables, such as temperature; and biotic variables, such as prey availability. However, there is a poor understanding of how distribution projections with biotic variables differ from those with abiotic variables, particularly in resource‐limited ...

From reels to research: Motivations and concerns of billfish citizen science participants

open access: yesPeople and Nature, Volume 7, Issue 11, Page 2956-2970, November 2025.
Abstract Citizen science facilitates cost‐effective ecological data collection at much larger scales than would otherwise be feasible. This is particularly useful for the study of highly migratory species with broad distributions, such as billfishes.

Interpretation of mercury content in national samples of sailfish (Istiophorus platypterus) and marlin (Makaira spp . Or Tetrapturus spp.) from international toxicological parameters

open access: yesCiencias Ambientales, 2014
Total mercury results in eleven samples of sail fish and eleven samples of marlin from national market places (where they are called with those names), from a study by the Costarican Fishing Federation, are presented.

Spatial and Temporal Heterogeneity of Fish Spawning Dynamics on the West Florida Shelf During Fall

open access: yesFisheries Oceanography, Volume 34, Issue 4, July 2025.
ABSTRACT Identifying spawning areas for economically and ecologically important fishes is critical for fisheries conservation and ecosystem‐based management. We used genetic barcoding to identify fish eggs collected across the West Florida Shelf (WFS) during September of 2013, 2014, and 2019.

On the Line and Online: Higher Non‐Response to Web‐Based Surveys Over‐Represents Avid Recreational Fishers Compared With Telephone Surveys

open access: yesFisheries Management and Ecology, Volume 32, Issue 3, June 2025.
ABSTRACT Recreational fishing surveys have an important role in providing data to inform fisheries management. The selection of a contact method is an important and often challenging consideration that influences the potential for non‐sampling errors that can result in unrepresentative data and biased estimates.

You Shall Not Pass: The Pacific Oxygen Minimum Zone Creates a Boundary to Shortfin Mako Shark Distribution in the Eastern North Pacific Ocean

open access: yesDiversity and Distributions, Volume 30, Issue 12, December 2024.
ABSTRACT Aim Shoaling of large oxygen minimum zones (OMZs) that form along eastern margins of the world's oceans can reduce habitat availability for some pelagic fishes. Our aim was to test the hypothesis that habitat compression caused by shoaling of the Pacific OMZ in tropical regions creates a boundary to the southern distribution of shortfin mako ...
