Genomics Detects Japanese and Pacific Sardine (Sardinops spp.) Hybrids in the Northeast Pacific Ocean

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
Using a newly developed nuclear Genotyping‐in‐Thousands‐by‐sequencing (GT‐seq) panel that unambiguously differentiates Japanese and Pacific Sardine, we report the first detection of Sardinops spp. hybrids. Previous genomic analyses of Pacific Sardine in the Northeast Pacific detected the presence of Japanese Sardine along the west coast of North ...

Anchovies in the English Channel [PDF]

open access: yesJournal of the Marine Biological Association of the United Kingdom, 1890
The anchovy belongs to the same family of fishes as the herring, pilchard, and sprat, the family Clupeidæ. But whereas the herring, pilchard, and sprat have so many structural features in common that they are placed in a single genus, namely Clupea, the anchovy is in many respects so peculiar that it is placed in the distinct genus Engraulis. There are

Admixture and Selection Driven by El Niño–Southern Oscillation Events Shape the Genetic Structure of Octopus mimus–O. hubbsorum Complex Across the Humboldt and South Equatorial Current Transition Zone

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
Whole‐genome sequencing of the Octopus mimus–O. hubbsorum complex in the eastern Pacific identified two main genetic clades—northern warm‐water and southern cold‐water lineages—with a broad admixture zone during ENSO years where admixed individuals reflect both their genomic makeup and local environments.

Comparative Analysis of Nutritional Values of Fishmeals Produced From Whole Anchovy and Sprat and Farmed Salmon Viscera in the Black Sea Region

open access: yesActa Natura et Scientia
Fishmeal is a nutrient-rich feed ingredient that is commonly used in commercial feed formulations for many species, primarily in the global aquaculture and pet food sectors.

Dietary partitioning mediates species coexistence in the high seas area of northwest Pacific

open access: yesEcography, Volume 2026, Issue 9, September 2026.
Niche partitioning, manifesting along various axes of the ecological niche, is a fundamental mechanism mediating species coexistence in a system. However, the emergence of many species in marine ecosystems would face considerable constraints in achieving coexistence through spatiotemporal differentiation mechanisms under the framework of niche ...

Linking species distribution models with population abundance to support adaptive fisheries management

open access: yesEcography, Volume 2026, Issue 9, September 2026.
Understanding how environmental variability structures essential fish habitat (EFH) is central to managing keystone populations in dynamic marine ecosystems. Using nearly three decades of standardized survey data (1994–2021) from the Adriatic Sea, we present the first basin‐scale, process‐based framework linking estimated habitat suitability and ...

Oyster reef habitat characteristics and nekton communities vary with restoration method in a large‐scale project

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Restoration in coastal ecosystems is revitalizing populations of foundation species that provide valuable habitat to support biodiversity and ecosystem services. The goals of oyster reef restoration include increasing oyster populations and oyster reef ecosystem services such as provision of habitat for commercially and ecologically valuable ...
