Electrophoretic analysis of protein variation in two Spanish populations of the European seabass, Dicentrarchus labrax L. (Pisces, Moronidae)

open access: yesAquaculture Research, 1991
. One hundred specimens of the European seabass. Dicentrarchus labrax L., from a natural population (Cadiz, Spain) were analysed by starch gel electrophoresis for 23 enzymes; 49 loci were identified, of which five were polymorphic (ADH*, AAT-3*, EST-.3*, MEP-1* and SOD-2*) P = 10·2% and HQ = 1·8%.

A Hazard Index of Microplastics Contamination in Commercial Marine Fish Species and Mussels in the Southern Marmara Sea, Turkey

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Microplastic (MP) pollution is an increasing concern in marine ecosystems due to the risk it poses to marine organisms and human health. This study aims to investigate the type, abundance, and properties of MPs in five commercially important fish species (Engraulis encrasicolus, Trachurus trachurus, Sardina pilchardus, Sarda sarda, and Dicentrarchus ...

Residents and Transients—Fish Community Dynamics in a Highly Anthropised Tidal North Sea Estuary Across the Annual Cycle

open access: yesJournal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
Tidal estuaries provide important spawning, nursery and feeding habitats for a wide diversity of species and serve as transit areas for diadromous fishes. However, they are globally among the most impacted aquatic ecosystems, pressured by anthropogenic alterations and global change.

Indications of recovery of anadromous fishes in a mid‐Atlantic estuary of North America: Spatial and seasonal patterns near a dam

open access: yesMarine and Coastal Fisheries, Volume 16, Issue 6, December 2024.
Abstract Objective Rivers on the east coast of North America once supported vast runs of anadromous fishes, such as Blueback Herring Alosa aestivalis and American Shad A. sapidissima. Declines in runs were attributed to, in part, dams and poor water quality that have since been improved by fishways and improvements to wastewater treatment, respectively.

eDNA Metabarcoding Analysis of Bony Fish Identification in Coastal Water of Gulf of Maine Using Nested Polymerase Chain Reaction of 12S rRNA Universal Primers

open access: yesEnvironmental DNA, Volume 6, Issue 6, November–December 2024.
ABSTRACT Ecosystems in coastal waters of Gulf of Maine (GOM) are undergoing environmental challenges in response to climate change and anthropogenic stressors. eDNA metabarcoding, a powerful tool for assessing the fish community structure, was used to identify fish communities in three types of GOM aquatic environments (sand, macroalgae, and eelgrass ...

Impact of acute cadmium exposure on the trunk lateral line neuromasts and consequences on the “C-start” response behaviour of the sea bass (Dicentrarchus labrax L.; Teleostei, Moronidae) [PDF]

open access: yesAquatic Toxicology, 2006
Behavioural responses of sea bass Dicentrarchus labrax were investigated after exposure to cadmium ions in laboratory-controlled conditions. The aim of this study was to discover whether environmental exposure to cadmium ions inactivates fish lateral line system neuromasts, and to determine the behavioural consequences of such a sensory blockage.

Feeding habits and ecological implications of the invasive Flathead Catfish in the Susquehanna River basin, Pennsylvania

open access: yesTransactions of the American Fisheries Society, Volume 153, Issue 5, Page 591-610, September 2024.
Abstract Objective Flathead Catfish Pylodictis olivaris are a widespread aquatic invasive species within the United States and a recent invader in the Susquehanna River basin, Pennsylvania. Flathead Catfish are piscivores known to consume native and recreationally important fish species. In the mid‐Atlantic United States, it is unknown how this invader

Century‐scale loss and change in the fishes and fisheries of a temperate marine ecosystem revealed by qualitative historical sources

open access: yesFish and Fisheries, Volume 25, Issue 5, Page 876-894, September 2024.
Century‐scale changes in principal fishery species, as revealed by rich qualitative historical sources. The plot shows the main species landed in four ports in northern Wales (Irish Sea, UK) in three different time periods, illustrating the loss of productive fish fisheries (herring; diverse demersal fishes), to modern‐day fisheries focusing on a few ...

What makes a habitat a home? Habitat associations of juvenile European sea bass, Dicentrarchus labrax, in estuarine nurseries

open access: yesJournal of Fish Biology, Volume 105, Issue 2, Page 539-556, August 2024.
Abstract Selection of nursery habitats by marine fish, such as European sea bass (Dicentrarchus labrax), is poorly understood. Identifying and protecting the full range of juvenile nursery habitats is vital to supporting resilient fish populations and economically important fisheries.
