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

Ecography, 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

People 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.

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

Fisheries 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.

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

Ciencias 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.

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

Fisheries 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.

Resource dynamics of the Indo-Pacific sailfish Istiophorus platypterus (Shaw, 1792) from the south-eastern Arabian Sea [PDF]

, 2012
The average billfish catch from the Indian EEZ during 2002-2007 was 4561 t which increased to 7856 t during 2008-2010, and nearly 80% of this was caught from the Arabian Sea by drift gillnet cum longline units.

Sailfish (Istiophorus platypterus) Habitat Utilization in the Southern Gulf of Mexico and Florida Straits with Implications on Vulnerability to Shallow-Set Pelagic Longline Gear [PDF]

, 2010
A total of 19 pop-up satellite archival tags (PSATs) were deployed on sailfish in the southern Gulf of Mexico between 2005 and 2007 aboard a commercial pelagic longline vessel (n = 18) and a recreational rod-and-reel vessel (n = 1).

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

Diversity 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 ...

Reproductive biology of blue marlin (Makaira nigricans) in the western Pacific Ocean [PDF]

, 2009
The reproductive biology of blue marlin (Makaira nigricans) was assessed from 1001 fish (ranging from 121 to 275 cm in eye-to-fork length; EFL) caught by Taiwanese offshore longliners in the western Pacific Ocean from September 2000 to December ...
