Bounds on Rényi and Shannon Entropies for Finite Mixtures of Multivariate Skew-Normal Distributions: Application to Swordfish (Xiphias gladius Linnaeus)

open access: yesEntropy, 2016
Mixture models are in high demand for machine-learning analysis due to their computational tractability, and because they serve as a good approximation for continuous densities.

When opportunistic predators interact with swordfish harpoon fishing activities: shark depredation over catches in the Strait of Messina (central Mediterranean Sea)

open access: yesThe European Zoological Journal, 2021
We describe the interaction between harpoon fishing activity and sharks, which opportunistically depredated harpoon catches in the Strait of Messina.

Revisiting Maturity Data: Using Oocyte Diameter and Gonadosomatic Index to Retroactively Apply a New Maturity Scale to Greenland Halibut (Reinhardtius hippoglossoides)

open access: yesFisheries Management and Ecology, Volume 33, Issue 3, Page 601-611, June 2026.
ABSTRACT Greenland halibut (Reinhardtius hippoglossoides) is a deep‐water flatfish which lives at temperatures of 1°C–4°C and produces large eggs (> 3 mm). The combination of low temperatures and large eggs has resulted in an unusual ovary development cycle, with vitellogenesis taking more than 1 year.

Effects of Kudoa thyrsites on Proximate Composition and Texture of Merluccius capensis and Zeus capensis

open access: yesJournal of Fish Diseases, Volume 49, Issue 6, June 2026.
ABSTRACT Kudoa thyrsites is a myxosporean endoparasite that infects fish, frequently resulting in myoliquefaction, impacting the texture and eating quality of fish muscle. The aim of this study was to investigate the effects of K. thyrsites infection on the proximate composition and texture parameters of raw fillets from two South African economically ...

Maternal Fish Intake in the Year Prior to Conception and Birth Defects, National Birth Defects Prevention Study, 1997–2011

open access: yesBirth Defects Research, Volume 118, Issue 5, May 2026.
ABSTRACT Background Epidemiologic data on the association between maternal fish intake and birth defects are sparse. Our objective was to assess associations between maternal fish intake and 52 different birth defects, most of which have not been assessed previously.

Trends in marine species distribution models: a review of methodological advances and future challenges

open access: yesEcography, Volume 2026, Issue 5, May 2026.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Population structure of Atlantic swordfish (Xiphias gladius L. 1758) (Teleostea, Xiphiidae) using mitochondrial DNA analysis: implications for fisheries management

open access: yesAnimal Biodiversity and Conservation, 2011
Recent studies on Atlantic swordfish (Xiphias gladius L. 1758) genetic structure have demonstrated significant heterogeneity but the precise boundary between populations remains to be identified. In this context, genetic diversity was investigated by PCR–

Temporal dynamics of mesopelagic fishes within a mesoscale eddy: A Lagrangian perspective

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Mesoscale eddies are physically dynamic environments, yet biological responses within them are often treated as static, with eddy polarity (anticyclones vs. cyclones) serving as the dominant conceptual framework. Temporal dynamics of animals within eddies—particularly at mid‐trophic levels—remain largely unresolved.

Historical review of the billfish management in the Mexican Pacific

open access: yesCiencias Marinas, 1998
Off the Mexican Pacific coast, high catch rates are found for striped marlin, sailfish and swordfish, and to a lesser extent for blue marlin and black marlin, making this area an important fishing ground for commercial and sport-fishing fisheries.

Analysis of Sea Turtle Bycatch by Andalusia Pelagic Longline Fleet in the Northeast Atlantic

open access: yesFisheries Oceanography, Volume 35, Issue 3, Page 386-396, May 2026.
ABSTRACT The Northeast Atlantic is one of the most crucial foraging grounds for juvenile loggerhead (Caretta caretta) and leatherback turtles (Dermochelys coriacea), while also serving as an important fishing area for the Andalusia surface longline fishery. The main aim of present study is to assess the sea turtle interaction with the Andalusia pelagic
