The molecular regulation of molting in the salmon louse (Lepeophtheirus salmonis)

open access: yes, 2021
The salmon louse, Lepeophtheirus salmonis, is a copepod and an ectoparasite that infects salmonids in the Northern hemisphere. At present, salmon louse infestations are the biggest threat to the health and welfare of wild and farmed fish, causing huge financial losses to the salmon farming industry annually.

Integrated Biomarker Assessment of Bifenthrin, Chlorpyrifos and Endosulfan Toxicity in Indigenous Carps (Catla catla and Labeo rohita): Oxidative Stress, Genotoxicity and Nuclear Alterations

open access: yesVeterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Combined exposure to bifenthrin–chlorpyrifos and bifenthrin–endosulfan mixtures induced oxidative stress, genotoxicity and nuclear abnormalities in Catla catla and Labeo rohita. Antioxidant and DNA damage biomarkers provide sensitive tools for assessing pesticide‐related ecological risks in aquatic environments. ABSTRACT Background The extensive use of

Optimization of calcium oxide treatment against salmon louse (Lepeophtheirus salmonis). A controlled laboratory study

open access: yesAquaculture Reports
Salmon louse (Lepeophtheirus salmonis) infestations pose a significant challenge to the salmonid farming industry. While most conventional water-treatment protocols primarily target lice at parasitic stages once attached to the fish, preventive measures ...

Conventional and Emerging Protein Ingredients in Farinaceous Products: Amino Acid Quality, Digestibility, Biological Value, and Functional Performance

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT The increasing demand for protein‐enriched foods has renewed interest in farinaceous products as widely consumed and technologically adaptable matrices for nutritional improvement. However, protein enrichment cannot be evaluated solely by increases in crude protein content, as nutritional value depends on essential amino acid (EAA) balance ...

A single cohort time delay model of the life-cycle of the salmon louse Lepeophtheirus salmonis on Atlantic salmon Salmo salar

open access: yes, 2002
A single cohort time delay differential equation model of Lepeophtheirus salmonis population dynamics was developed. The model was parameterised using data from tank infection trials, which followed a single experimental cohort of post-settlement lice ...

Supplementing beef cattle diets with brown seaweed affects coprophagous beetles' dung use

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 4, Page 535-547, November 2026.
Supplementing beef cattle diets with brown seaweed reduced the attractiveness of dung for a common dung beetle (Onthophagus nuchicornis). Dietary supplementation with brown seaweed appeared to reduce the proportion of major males in the F1 generation.

Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

open access: yesFish and Fisheries, Volume 27, Issue 6, Page 1245-1268, November 2026.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.
