Reducing discards in a demersal purse-seine fishery [PDF]

open access: yes, 2008
Fisheries bycatches and discards constitute a significant problem in many fisheries worldwide. Unlike the pelagic purse-seine, the demersal purse seine usually targets high commercial value demersal species such as sea breams ( e.

Exploring fidelity of Sardines (Sardina pilchardus) to feeding grounds in the Atlantic Moroccan waters using stable isotope analyses (C, N) and otolith microchemistry

open access: yesFrontiers in Marine Science, 2015
The Atlantic Moroccan waters (21°-29°N) are part of the Canary Current Large Marine Ecosystem and are enriched by highly productive upwelling systems. Sardine (Sardina pilchardus) is both the most abundant forage fish in this area and the most heavely ...

Multi‐Seasonal eDNA Metabarcoding Highlights a Resurgence in Fish Diversity Across a Severely Impacted Estuarine Ecosystem

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

Insights into ‘Srdelara’ Purse Seines: Landing Composition and Trophic Relationships in the Pelagic Food Web

open access: yesFishes
This study analysed commercial ‘Srdelara’ purse seine landings in the Central Eastern Adriatic from November 2020 to March 2022. The observed commercial landings demonstrated typical seasonal variations, with a peak from September to November and the ...

Analysis of polycyclic aromatic hydrocarbons in fish: optimisation and validation of microwave-assisted extraction [PDF]

open access: yes, 2012
An accurate and sensitive method for determination of 18 polycyclic aromatic hydrocarbons (PAHs) (16 PAHs considered by USEPA as priority pollutants, dibenzo[a,l]pyrene and benzo[j]fluoranthene) in fish samples was validated.

Ecosystem Impacts of the Landing Obligation for Unwanted Catch in Thermaikos Gulf (Greece)

open access: yesFisheries Management and Ecology, Volume 33, Issue 2, Page 246-259, April 2026.
ABSTRACT Discards by marine commercial fisheries have been an issue of major concern to the scientific community in recent years. We modeled the ecological and trophic consequences of a mandatory landing obligation (LO) regulated by the reformed Common Fisheries Policy [Regulation (EU) 1380/2013] on the Thermaikos Gulf ecosystem (northwestern Aegean ...

Gill monogeneans of the chub mackerel, Scomber japonicus from Madeiran waters of the Atlantic Ocean, Portugal [PDF]

open access: yesJournal of Helminthology, 2007
AbstractFive species of monogeneans were recovered from the gill filaments of 181 chub mackerel, Scomber japonicus, from the Madeiran waters of the Atlantic Ocean, Portugal, during 2004/2005. The monogenean Pseudokuhnia minor showed the highest prevalence (98.68%) and a mean intensity of 28.23, followed by Kuhnia scombri (prevalence of 43.71% and mean ...

Unveiling Patterns in Cetacean Strandings Along Southern Atlantic Iberia: Temporal and Spatial Trends, Seasonality, and Causes of Death

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT We compiled 46 years of cetacean strandings in the Algarve, Portugal, describing temporal–spatial patterns, size–sex structure, and causes of death (COD). We analyzed national records and years with a dedicated regional stranding network (SN) to assess annual/seasonal trends, spatial hotspots, and compare biometrics and COD.
