Mapping Escolar (Lepidocybium flavobrunneum) in Motion: Oceanographic Forces Shaping Its Habitat in the Southwestern South Atlantic, With Insights From Fishers' Perceptions

Fisheries Oceanography, Volume 35, Issue 3, Page 445-461, May 2026.
ABSTRACT Lepidocybium flavobrunneum [Smith, 1843], commonly known as escolar, is a large pelagic species, important for global and local fisheries, particularly in the southwestern South Atlantic Ocean (SWAO), where it constitutes a significant portion of the catch.

Brain Morphology and Quantitative Assessment of Sensory Brain Areas in Southern Bluefin Tuna, Thunnus maccoyii (Scombridae, Teleostei)

Journal of Comparative Neurology, Volume 534, Issue 4, April 2026.
The absolute and relative volume of major sensory and integrative brain regions of the southern bluefin tuna Thunnus maccoyii are examined using magnetic resonance imaging (MRI). A dominant cerebellum projects into the midbrain ventricular space, while the optic tectum represents a smaller proportion of total brain volume than previously estimated ...

DECLINE IN FRESHNESS OF SKIPJACK TUNA ALONG THE DISTRIBUTION CHAIN FROM LANDING SITES TO LOCAL CONSUMERS IN TERNATE

Jurnal Teknologi Perikanan dan Kelautan
Proper handling of fish is a key factor influencing the success of fresh fish distribution and trade. However, in practice, handling procedures are often inadequately implemented by fishermen, resulting in reduced fish quality and price.

Comparative study of skipjack tuna Katsuwonus pelamis (Scombridae) fishery stocks from the South Atlantic and western Indian oceans

Scientia Marina, 2019
The skipjack tuna, Katsuwonus pelamis, inhabits tropical and subtropical oceans the world over, and contributes substantially to total tuna catches. Both fishing pressure and anthropic influences affect skipjack populations, impacting on economic returns

Global Marine Fishery Stock Productivity Under Climate Change

Global Change Biology, Volume 32, Issue 3, March 2026.
In this uniquely extensive global analysis on the productivity of commercial fishery stocks, a common factor was the existence of pronounced heterogeneity, as documented for 710 stocks in the undertaken hindcast over the last decades. Importantly, both winners and losers appear under on‐going climate change, and then seemingly are equally present ...

Evidence for a fisher‐designed solution to manta and devil ray bycatch in tuna fisheries

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Bycatch in global tropical tuna purse seine fisheries represents a significant source of mortality for manta and devil rays (mobulids), which are globally threatened. Use of best handling and rapid release practices on purse seine vessels can substantially reduce mortality and improve vulnerability status for mobulids.
