Cleaner fish are commonly used as a control measure against salmon lice infestations in salmonid farms. Lumpfish (Cyclopterus lumpus) is the most common cleaner fish species used in Norwegian farms. However, little is known about how different operational, including environmental, conditions affect ...

The use of cleaner fish, such as the ballan wrasse (Labrus bergylta), is important for combatting the sea lice problem in salmonid cage farming. Ballan wrasse is the only wrasse species that is cultivated, though only about 50% of the approx. 3 million ballan wrasse used in 2020 was produced by...

Cleaner fish such as lumpfish (Cyclopterus lumpus) are widely used as a biological method for delousing in Atlantic salmon (Salmo salar) aquaculture. Previous studies have mainly focused on the number of salmon lice (Lepeophtheirus salmonis) per salmon or on the proportion of individuals grazing on ...

We used 4 years of publicly available data (2016-2019) on chemical usage at salmon sites with information on production, stocking, locations and environmental conditions to explore patterns of anti-sea lice treatments in a Canadian province. Results show that sequential chemical treatments are...

Draft genome sequences of 23 Tenacibaculum sp. strains that were isolated from Cyclopterus lumpus (lumpfish) were investigated to elucidate possible routes of transmission between Salmo salar (Atlantic salmon) and lumpfish.

The production of lumpfish (Cyclopterus lumpus) is increasing rapidly due to their use as a cleaner fish for sea lice infections in Atlantic salmon farming. The sustainable development of captive broodstocks is reliant on good egg quality however this remains unknown. The present study assessed the ...

Infestations by the salmon louse (Lepeophtheirus salmonis Krøyer) represents the major fish health problem that the Atlantic salmon (Salmo salar) industry has to face. Sea lice infestation has a large impact on the economy of fish farmers, which are looking for a cost-effective and environmentally...

MicroRNAs (miRNAs) are endogenous small RNA molecules involved in the post-transcriptional regulation of protein expression by binding to the mRNA of target genes. They are key regulators in teleost development, maintenance of tissue-specific functions, and immune responses. Lumpfish (Cyclopterus...

The development of effective vaccines is a critical step towards the domestication of emerging fish species for aquaculture. However, traditional vaccine delivery through intraperitoneal (i.p.) injection requires fish to reach a minimum size and age and therefore cannot provide protection at early...

This articles describes the development and application of The Lumpfish Welfare Watcher to measure the welfare of lumpfish (Cyclopterus lumpus) used as biological control agents against sea lice in cultured salmon in the UK. This includes four complementary welfare tools: (1) a diagnostic chart for ...
