Reconstructing discards profiles of unreported catches

Scientia Marina, 2018
In Portugal it has been estimated that unreported catches represent one third of total catches. Herein, information on landings and total unreported catches (discards) by commercial métier were disaggregated into high taxonomic detail using published ...

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

Integrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Mobility of organochlorines in muscle of sardine (Sardina pilchardus) during spawning in the Portuguese coas

Ciencias Marinas, 2006
 Concentrations of polychlorinated biphenyls (PCBs), p,p'-dichlorodiphenyltrichloroethane (DDT) and metabolites, and dieldrin were determined in muscle tissues of female and male sardines (Sardina pilchardus) obtained between February 2000 and January ...

Oxytetracycline as an otolith chemical marker in Atlantic bluefin tuna (Thunnus thynnus): Technical feasibility in culture

Journal of Fish Biology, EarlyView.
Abstract Reliable discrimination between wild and cultured fish is essential for traceability in aquaculture. This study reports the first successful application of intramuscular oxytetracycline (OTC) injection for otolith marking in juveniles of Atlantic bluefin tuna (Thunnus thynnus).

Relative role of life-history traits and historical factors in shaping genetic population structure of sardines (Sardina pilchardus)

BMC Evolutionary Biology, 2007
Background Marine pelagic fishes exhibit rather complex patterns of genetic differentiation, which are the result of both historical processes and present day gene flow.

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish

Fish and Fisheries, Volume 27, Issue 4, Page 850-864, July 2026.
ABSTRACT Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing ...

Physicochemical and spectroscopic characterization, and evaluation of the antioxidant and anti-inflammatory potential of oils extracted from Thunnus thynnus and Sardina pilchardus coproducts

Grasas y Aceites
This work aims to valorize the coproducts of two pelagic species, bluefin tuna (Thunnus thynnus) and sardines (Sardina pilchardus), by the extraction and characterization of the oil coproducts through physicochemical and FTIR-ATR analysis and the in ...

Foraging Ecology and Fisheries Interactions of Common Bottlenose Dolphins (Tursiops truncatus) Inferred From Strandings in Western Iberian Atlantic Waters

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The common bottlenose dolphin (Tursiops truncatus) is a resident species along the Portuguese mainland coast, yet knowledge of its stranding patterns and feeding ecology is scarce. This study presents a comprehensive assessment of strandings (n = 264, from 1980 to 2019) and feeding ecology based on stomach content analysis (n = 43 from 1997 to
