Genetically confirmed first records of an egg and a juvenile roundscale spearfish, Tetrapturus georgii

Journal of Fish Biology, Volume 106, Issue 6, Page 1696-1703, June 2025.
Abstract The roundscale spearfish (Tetrapturus georgii) is a poorly studied species with limited information available on its biology, ecology, and population status. Although the adult life stage of the species is morphologically distinguishable from closely related species such as the overexploited white marlin (Kajikia albida), misidentification is ...

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 ...

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.

Evidence for a by‐product mutualism in a group hunter depends on prey movement state

Functional Ecology, Volume 38, Issue 10, Page 2123-2138, October 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Group‐hunting animals have been shown to engage their prey in long pursuits (kms) to increase capture success, but the evidence for this is limited to a few terrestrial species.

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 ...

Impact of mercury released from permafrost on food safety in Switzerland

Food Risk Assess Europe, Volume 2, Issue 4, October 2024.
ABSTRACT Climate change has caused the permafrost to thaw, releasing the previously sequestered mercury into the environment. Mercury has the ability to convert to methylmercury, a bioaccumulative neurotoxin. Exposure occurs in humans through the ingestion of contaminated food and it is associated with adverse health effects.

Short communication: Identification of by-catch species of tuna purse seiners in Iranian waters of Oman Sea [PDF]

, 2018
One of the most visible direct impacts of fishing is the capture of non-target species, known collectively as by-catch. By-catch includes species that are unwanted and discarded (discards) and species that are retained and sold (byproduct) (Stobutzki et

Measuring deoxygenation effects on marine predators: A new animal‐attached archival tag recording in situ dissolved oxygen, temperature, fine‐scale movements and behaviour

Methods in Ecology and Evolution, Volume 15, Issue 8, Page 1360-1379, August 2024.
Abstract Global climate‐driven ocean warming has decreased dissolved oxygen (DO) levels (ocean deoxygenation) leading to expansions of hypoxic zones, which will affect the movements, behaviour, physiology and distributions of marine animals. However, the precise responses of animals to low DO remains poorly understood because movements and activity ...

The vulnerability of sharks, skates, and rays to ocean deoxygenation: Physiological mechanisms, behavioral responses, and ecological impacts

Journal of Fish Biology, Volume 105, Issue 2, Page 482-511, August 2024.
Abstract Levels of dissolved oxygen in open ocean and coastal waters are decreasing (ocean deoxygenation), with poorly understood effects on marine megafauna. All of the more than 1000 species of elasmobranchs (sharks, skates, and rays) are obligate water breathers, with a variety of life‐history strategies and oxygen requirements.

Phylogenetic patterns in fossil and living billfishes (Istiophoriformes, Istiophoridae): evidence from the Central Mediterranean

Papers in Palaeontology, Volume 10, Issue 4, July/August 2024.
Abstract Study of the relationships of fossil and living billfishes is crucial for understanding the ecological drivers that control their biodiversity through time and how distributional patterns of extant populations may be affected by current abiotic events.
