Geographic Patterns of Intra‐ and Interspecific Diversity of Riverine Fish Species in the Italian Northern Apennines and Ligurian Alps

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We investigated the suitability of environmental DNA (eDNA) metabarcoding to identify inter‐ and intraspecific diversity patterns of riverine fish populations across the Adriatic and Ligurian drainage basins in Northern Italy. Our results revealed genetic as well as community differentiations, with the Adriatic side displaying higher taxon richness ...

Techno-economic considerations of shark driftnet fishery, off Lagos coast, Nigeria [PDF]

, 1983
Experimental fishing operations with driftnets were conducted in Lagos coastal waters with a view to finding out appropriate gear for effective exploitation of sharks and other pelagic fish species that are not normally caught in trawls.

New information from fish diets on the importance of glassy flying squid (Hyaloteuthis pelagica) (Teuthoidea: Ommastrephidae) in the epipelagic cephalopod community of the tropical Atlantic Ocean [PDF]

, 2007
Squids of the family Ommastrephidae are a vital part of marine food webs and support major fisheries around the world. They are widely distributed in the open ocean, where they are among the most abundant in number and biomass of nektonic epipelagic ...

Hormonal regulation of the phenotype into environmentally appropriate pace‐of‐life syndromes

Fish and Fisheries, Volume 26, Issue 1, Page 16-29, January 2025.
Abstract The risk of predation is an important driver that tailors life histories in various ways. Using an evolutionary model based on hormonal control, we study how different predation regimes affect adaptive risk‐taking and growth in fish populations.

Swordfish ( Xiphias gladius, Teleostea: Xiphiidae) surface behaviour during reproductive period in the central Mediterranean Sea (southern Tyrrhenian Sea)

Marine Biodiversity Records, 2009
Swordfish in the Mediterranean Sea have been caught with harpoon since 1000 BC, when, from May to August, these animals come to the surface often in male–female pairs. At this time, swordfish exhibit a variety of swimming behaviours largely only known by fishermen targeting swordfish.

Composition of pelagic fish in commercial landings of the longline fishery in the Costa Rica Pacific during 2015-2021

Frontiers in Marine Science
Longline fishing in the Pacific of Costa Rica targets multiple species of large pelagic fishes and faces challenges in assessment due to lack of data.

Toward identification of larval sailfish (Istiophorus platypterus), white marlin (Tetrapturus albidus), and blue marlin (Makaira nigricans) in the western North Atlantic Ocean* [PDF]

, 2005
The identification of larval istiophorid billfishes from the western North Atlantic Ocean has long been problematic. In the present study, a molecular technique was used to positively identify 27 larval white marlin (Tetrapturus albidus), 96 larval blue ...

Twenty‐three years of PCR‐based seafood authentication assay development: What have we learned?

Comprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 4, July 2024.
Abstract Seafood is a prime target for fraudulent activities due to the complexity of its supply chain, high demand, and difficult discrimination among species once morphological characteristics are removed. Instances of seafood fraud are expected to increase due to growing demand.

Length-weight relationships of marine fishes from the central Brazilian coast [PDF]

, 2004
Parameters of the length-weight relationship are presented for 85 fish species from the marine and estuarine regions of the central Brazilian coast (latitude 13° to 23° S). Three different methods were used. A non-linear iterative process using the quasi-

Primer set evaluation and sampling method assessment for the monitoring of fish communities in the North‐western part of the Mediterranean Sea through eDNA metabarcoding

Environmental DNA, Volume 6, Issue 3, May–June 2024.
Schematic representation of the sampling method. Surface sampling is conducted from a boat with a pump allowing live water filtration through an enclosed capsule. Bottom sampling is performed simultaneously on the same transect, with an underwater pump connected to an enclosed capsule and fixed on a DPV driven by a diver.
