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

Plant-Made Nervous Necrosis Virus-Like Particles Protect Fish Against Disease

Frontiers in Plant Science, 2019
Virus-like particles (VLPs) of the fish virus, Atlantic Cod Nervous necrosis virus (ACNNV), were successfully produced by transient expression of the coat protein in Nicotiana benthamiana plants.

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 ...

Bentonite-supplemented diets improved fish performance ammonia excretion haemato-biochemical analyses immunity antioxidants and histological characteristics of European seabass Dicentrarchus labrax

Scientific Reports
The purpose of this research was to examine the potential effects of bentonite (BN) supplemented diets on growth, feed utilization, blood biochemistry, and histomorphology of Dicentrarchus labrax. Six treatments in triplicate were tested: B0, B0.5, B1.0,

Wheat gluten as a partial substitute for fish meal protein in sea bass (D. labrax) diets

Italian Journal of Animal Science, 2011
Previuos investigations have shown wheat gluten meal (WGM) to be a promising candidate ingredient to replace fish meal (FM) in sea bass diets, based on its high crude protein content and biavailability and the absence of antinutritional factors in the ...

Seasonal Length–Weight Relationships of European Sea Bass (Dicentrarchus labrax) in Two Aquaculture Production Systems

Fishes, 2023
Different non-intrusive methods have been developed to estimate fish biomass, which is a determinant factor for aquaculture farming management. Length–weight conversion is a crucial parameter for accurate biomass estimation.

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.

Early ontogenic development of the fatty acid composition in seabass (Dicentrarchus labrax) eggs and juveniles from captive broodstocks

Marine Science and Technology Bulletin, 2014
In the present study, effects of different diets on the fatty acid composition of hatched seabass (Dicentrarchus labrax) at after fertilization of the egg (E), and yolk sac (Y) stages have been investigated.
