Lice shielding skirts are a preventative measure against salmon lice in Atlantic salmon farming. The skirt is wrapped around the top meters of the net cage to divert the current flow around the cage, and thereby keep the salmon lice out. Despite these skirts being used actively in Norwegian ...

The COVID-19 pandemic has wreaked havoc on the aquaculture and fisheries sector all around the world, with the impact being exacerbated in developing countries. This study is an endeavor to identify consequences of the COVID-19 on fisheries and aquaculture sectors based on primary data collected...

In this paper we present a suggestion for a sustainability assessment framework using genome editing of salmon as a case study. The salmon farming industry is facing several challenges hindering sustainable production. Genome editing has entered as a tool that can improve selective breeding and...

Research reporting user trait preferences for fish, particularly in relation to guiding genetic improvement programs are rare, even in tilapia where demand for genetically improved fish has underpinned the expansion of fish farming. The present study investigated gender-disaggregated trait...

Thermal delousing has become the most applied method for treatment against salmon lice. However, the temperature range used is strongly aversive for salmonids, and the method is associated with increased mortality. Treatment temperature × duration combinations should be tailored to maximise...

The ectoparasites Dactylogyruslamellatus usually infest fish gills and cause severe damage to the gill tissues of the host. However, whether the ectoparasites influence gut microbiota is still unknown. In this study, gut microbiota combined with histopathological characteristics, biochemical...

Ichthyophthirius multifiliis (Fouquet, 1876) is a highly pathogenic ciliate of freshwater fish that threatens the global aquaculture. During the investigations of ichthyophthiriasis in China, a total of sixteen I. multifiliis isolates were collected from four provinces, Hubei, Hunan, Guangdong, and ...

Tapeworms are infamous and highly successful invasive parasites in aquatic animals, especially in fish. However, tapeworm-caused diseases in soft-shelled turtles are rarely discovered. In this study, a case of cultured Chinese soft-shelled turtle (Pelodiscus sinensis) infected with tapeworm in...

Ichthyophthirius multifiliis is a ciliated ectoparasite that infects almost all freshwater fishes with low host specificity. However, an endemic fish in the upper Yangtze River, Percocypris pingi, was thought by aqua-culturists to be completely resistant to I. multifiliis. We therefore aimed to...

The ionic profile of inland low salinity water sources can be dramatically different with variable concentrations of magnesium (Mg²⁺). Inland shrimp farmers in Alabama, USA, supplement Mg²⁺ at the start of each production cycle to reach concentrations >20 mg/L at 1 to 11 g/L salinities. However, ...
