Commercial clays in cosmetic formulations for hair care: Characterization and application to improve the mechanical properties of hair fibre

International Journal of Cosmetic Science, EarlyView.
The shampoo and conditioner bar formulations enhanced hair gloss, promoting softness, improved cuticle alignment, and effective protection of hair shafts against external aggressors. Findings from mechanical properties measurements indicate that the clay‐containing formulations enhance the mechanical strength of hair, contributing to stronger and more ...

Evaluation of a national operational salmon lice monitoring system—From physics to fish

PLoS ONE, 2018
The Norwegian government has decided that the aquaculture industry shall grow, provided that the growth is environmentally sustainable. Sustainability is scored based on the mortality of wild salmonids caused by the parasitic salmon lice.

Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

Journal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

Major vault protein is part of an extracellular cement material in the Atlantic salmon louse (Lepeophtheirus salmonis)

Scientific Reports
Major vault protein (MVP) is the main component of the vault complex, which is a highly conserved ribonucleoprotein complex found in most eukaryotic organisms.

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Evaluation of Three Atlantic Salmon Strains for Resistance to Copepodid Sea Lice Attachment

Fishes
Sea lice have been a persistent pest of the salmon farming industry for more than 50 years. In this study, we aimed to identify if different strains of Atlantic salmon with discrete long-term lice exposure histories had variable resistance to copepodid ...

Optimal salmon lice treatment threshold and tragedy of the commons in salmon farm networks

Aquaculture, 2019
The ectoparasite Lepeophtheirus salmonis has for decades plagued salmon aquaculture by decreasing profits and impacting wild salmon stocks. To protect migrating wild salmon stocks and avoid excessive cross-farm infections, authorities require treatments ...

Bath Treatments With Emamectin Benzoate Control Dactylogyrideans Infecting Colossoma macropomum Gills Without Altering Physiology of This Host Fish

Journal of Fish Diseases, EarlyView.
ABSTRACT Intensification of fish aquaculture worldwide has led to severe problems of diseases caused by parasitic dactylogyrideans. In this study, the anti‐dactylogyridean efficacy of treating Colossoma macropomum with baths of emamectin benzoate (EMB) was investigated for the first time, along with the effects of this treatment on the haematology and ...

Biofouling on Salmon Pen Nets and Cleaner Fish Shelters Does Not Harbor Planktonic Stages of Sea Lice

Frontiers in Marine Science, 2020
The objective of the current study was to determine the extent to which planktonic sea lice (Lepeophtheirus salmonis Krøyer, 1838 and Caligus elongatus Nordmann, 1832) were present in the biofouling on open-sea net pens used for commercial rearing of ...

Epidemiology of Salmonid Rickettsial Septicemia (SRS) in Farmed Salmon: The Role of Sea Lice Infestations in Mortality Risk

Journal of Fish Diseases, EarlyView.
ABSTRACT Piscirickettsia salmonis , the causal agent of salmonid rickettsial septicemia (SRS), is the main pathogen affecting farmed salmonids in Chile. Outbreaks of SRS lead to substantial economic losses for producers. Many determinants related to SRS outcomes are still poorly understood.
