Abstract Hydrogen peroxide (H 2 O ) is a commonly used treatment for range of parasitic diseases marine finfish, including amoebic gill disease (AGD). While this partially effective at reducing parasite load, H can have detrimental effects on the host under certain conditions. Treatment temperature and dose concentration are two factors that known to influence toxicity ; however, their impact outcome AGD remains unclear. Here, we investigated (8, 12 or 16°C) (750, 1,000, 1,250 mg/L) efficacy...
The gill mucosal microbiome of Atlantic salmon has a significant impact on health and physiology under homeostatic conditions, but the microbial community may itself be influenced by host genetics, culture system seawater transfer. In this study, two commercial strains salmon, reared in parallel hatchery systems (flow-through -FT recirculation -RAS) was investigated. Samples microbiome, tank biofilm water were collected from fish cohorts at hatcheries following Though commercially equivalent...
To investigate the relationship between microbial community profiles and gill pathology during a production cycle of Atlantic salmon in two commercial hatcheries.Relationships histology, environmental conditions, microbiome were determined using high-throughput data, including 16S rDNA amplicon sequencing histopathology water quality parameters. Hatchery A used riverine operated mixed system recirculation aquaculture (RAS) flowthrough. B was bore RAS. Melanin deposits, hyperplastic,...
ABSTRACT Nodular gill disease (NGD) is a serious proliferative condition that affects farmed salmonids, particularly in Europe. While the cause of NGD remains unknown (and maybe multifactorial), various amoebae are often isolated from gills affected fish and can some cases be seen associated with lesions by histopathology. The present study aimed to quantify abundance different amoeba species directly rainbow trout healthy controls. An 18S rRNA amplicon metagenomic approach was employed...
Amoebic gill disease (AGD), caused by Neoparamoeba perurans, is a major health challenge for Atlantic salmon aquaculture globally. While freshwater bathing 2 hr effective in reducing infection severity, there need more rapid and lower cost alternatives. To this end, combination of sodium percarbonate (SPC) was examined its treatment efficacy. Initial vitro studies showed reduction amoeba viability when exposed 30 min to containing >500 mg/L SPC. Subsequently, AGD-affected were bathed 16°C...
Epitheliocystis, an intracellular bacterial infection in the gills and skin epithelium, has been frequently reported Atlantic salmon (Salmo salar) during freshwater production a number of countries. This study describes prevalence intensity natural epitheliocystis present two strains reared either flow-through (FT) or recirculation aquaculture system (RAS) Ireland. Repeated sampling prior to throughout seawater transfer, histology quantitative real-time PCR were used determine intensity....
