Research could help improve the welfare of farmed lumpfish, a species used to control sea lice in salmon

Date
10 June 2020
Abstract

The lumpfish Cyclopterus lumpus is commercially exploited in numerous areas of its range in the North Atlantic Ocean, and is important in salmonid aquaculture as a biological agent for controlling sea lice. Despite the economic importance, few genetic resources for downstream applications, such as...

Abstract

There is increased commercial interest in the production of Lumpfish (Cyclopterus lumpus, Linnaeus, 1758) as a biological control for sea lice infections in Atlantic salmon farming. To ensure sustainability, reliable captive breeding is required however, optimal husbandry conditions for broodstock...

Abstract

Cleaner fish used as a biological control agent against salmon lice is rapidly increasing in Atlantic salmon aquaculture. However, concerns have been raised about the welfare and mortality of cleaner fish in salmon cage systems, which could in turn affect their performance in controlling salmon...

Abstract

The use of lumpfish in salmon farming allows the removal of sea lice all year round, without the use of chemicals or mechanical treatments. In Norway alone, around 31 million lumpfish are currently put into sea pens whereas no efficient method to re-catch these fish once they no longer are...

Abstract

The interleukin (IL)-1 family play a fundamental role as immune system modulators. Our previous transcriptome-analyses of leukocytes from lumpfish (Cyclopterus lumpus L.) showed that IL-1β was among the most highly upregulated genes following bacterial exposure. In the present study, we...

Abstract

Ballan wrasse (Labrus bergylta) are used as cleaner fish in commercial Atlantic salmon farming to remove ectoparasitic sea lice. While the delousing performance of wild wrasse is usually good, that of farmed wrasse is variable, possibly because of different conditions in hatcheries and sea cages....

Abstract

Cleaner wrasse eat sea lice (Lepeophtheirus salmonis) directly from the skin of the Atlantic salmon (Salmo salar). To reduce harvest from the wild wrasse populations and to increase the quality and availability of cleaner fish, lumpfish (Cyclopterus lumpus) have been increasingly developed as a...

Abstract

The commercial production of lumpfish Cyclopterus lumpus L. is expanding with the increased demand for their use as cleaner fish, to control sea-lice numbers, at marine Atlantic salmon Salmo salar L. aquaculture sites throughout Northern Europe. A new ranavirus has been isolated from lumpfish at...

Abstract

Lumpfish (Cyclopterus lumpus) is the most widely use biological pest control agent to delouse sea lice on Atlantic salmon (Salmo salar). From 2012 to 2017, the production of lumpfish has increased from less than two million individuals to more than 30 million individuals in Norway alone. To meet...
