Impact of Climate Change on Some Seasonal Bacterial Eruptions among Cultured Marine Fishes from Egyptian Coastal Provinces [PDF]

Journal of Applied Veterinary Sciences
Climate change is now considered one of the greatest challenges and is expected to have a drastic impact on mariculture. The present study aimed to evaluate the impact of climatic changes on the emergence of bacterial pathogens among cultured marine fish

Genetic structuring in farmed and wild Gilthead seabream and European seabass in the Mediterranean Sea: implementations for detection of escapees

Aquatic Living Resources, 2020
Microsatellite markers were used to investigate the genetic structure of the two most important cultured fish in the Mediterranean Sea, the gilthead seabream (Sparus aurata) and the European seabass (Dicentrarchus labrax), from two (one wild and one ...

Chronic thermal stress affects growth, liver morphology and molecular responses but allows recovery at optimal temperature in juvenile zebrafish (Danio rerio)

Journal of Fish Biology, EarlyView.
Abstract Climate‐driven aquatic heatwaves pose an increasing threat to fish populations by inducing prolonged thermal stress. However, the resilience of teleosts to chronic heat exposure and their capacity for recovery remains poorly understood. This study investigated the effects of chronic high‐temperature exposure on juvenile zebrafish (Danio rerio).

Integrating environmental DNA, diving surveys and DNA barcoding to track endangered twaite shad (Alosa fallax) spawning sites

Journal of Fish Biology, EarlyView.
Abstract The twaite shad (A. fallax), an anadromous fish species belonging to the Clupeidae family, has experienced population declines throughout Europe. This decline is attributable to a range of anthropogenic pressures, including migration barriers, environmental pollution, habitat degradation, predation by invasive species and unsustainable fishing

Effect of in vitro exposure to cadmium and copper on sea bass blood cells

Italian Journal of Animal Science, 2010
Blood cells freshly collected from sea bass (Dicentrarchus labrax) were exposed in vitro to different concentrations of cadmium (Cd) and copper (Cu) at 10-7 M, 10-5 M, 10-3 M, and exam- ined for neutral red retention capacity and for cell vitality with ...

Mitochondrial respiratory capacities are not linked to individual variation in hypoxia tolerance and standard metabolic rate in European seabass Dicentrarchus labrax

Journal of Fish Biology, EarlyView.
Abstract In hypoxic environments, fish attempt to regulate their metabolic rate as oxygen levels in the water decline. Individuals that have low energy requirements for maintenance – standard metabolic rate (SMR) – are expected to have higher hypoxia tolerance, measured as the critical water oxygen saturation threshold (Scrit) below which they cannot ...

Altered photoperiod affects behaviour in a key fish grazer, the thinlip grey mullet, Chelon ramada

Journal of Fish Biology, EarlyView.
Abstract The aim of this study is to address experimentally the immediate impacts of an alteration of the photoperiod, simulating an extreme artificial light pollution, on the behaviour and stress of a key grazer fish common in temperate coastal ecosystems in Europe, the thinlip grey mullet, Chelon ramada.

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response

Journal of Fish Biology, EarlyView.
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

Expanding the Fish‐Brain Invitrome With the Senegalese Sole SsB‐1 Cell Line—A Versatile Model for Neurotropic Virus Research

Journal of Fish Diseases, EarlyView.
ABSTRACT Cell lines are essential tools for studying animal physiology and immunopathology, reducing the use of live animals and supporting the 3Rs principle of reduction, refinement, and replacement. The Senegalese sole (Solea senegalensis), a relevant species for Spanish aquaculture diversification, lacks established in vitro models. We developed SsB‐
