Interleukin-1 Ligands and Receptors in Lumpfish (Cyclopterus lumpus L.): Molecular Characterization, Phylogeny, Gene Expression, and Transcriptome Analyses

Frontiers in Immunology, 2020
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 ...

A Screening Study on Effects Varying Dietary Macronutrient Composition on Gut Functions in Lumpfish (Cyclopterus lumpus)

Frontiers in Marine Science, 2022
Cultivation of lumpfish (Cyclopterus lumpus) as lice cleaner fish for salmon is now expanding. For successful cultivation of a new species, understanding the basic biology of digestive functions is vital to facilitate and optimize diet formulation.

A half century of monitoring reveals contrasting survival responses of Icelandic seabirds to climate and fisheries pressures

Ibis, Volume 168, Issue 3, Page 950-971, July 2026.
Seabirds serve as key indicators of marine environmental changes, with adult survival being a critical parameter for assessing population health. Iceland hosts some of the largest seabird populations in the North Atlantic, making it a valuable location for studying long‐term trends in seabird demographics.

Towards a better understanding of the evacuation time of salmon lice (Lepeophtheirus salmonis) in lumpfish (Cyclopterus lumpus)

Aquaculture Reports
Cleaner fish are utilised as a preventive control measure against sea lice infestations in salmon farms. In recent years, lumpfish (Cyclopterus lumpus) has been the most commonly deployed cleaner fish species in Norway.

Ultrasonography as a non‐invasive technique to assess the effects of diet on the ovaries of female European seabass (Dicentrarchus labrax)

Journal of Fish Biology, Volume 109, Issue 1, Page 531-541, July 2026.
Abstract Broodstock management in aquaculture aims to optimise larval production to meet farm demand, which requires precise monitoring of the reproductive cycle. Traditional methods such as histology often require killing of fish, making them unsuitable for monitoring reproductive dynamics at fish level.

Cohabitation With Atlantic Salmon (Salmo salar) Affects Brain Neuromodulators But Not Welfare Indicators in Lumpfish (Cyclopterus lumpus)

Frontiers in Physiology, 2022
Lumpfish are utilized to combat ectoparasitic epidemics in salmon farming. Research gaps on both cleaning behavior and client preferences in a natural environment, emphasizes the need to investigate the physiological impacts on lumpfish during ...

Lack of Lumpfish (Cyclopterus lumpus) Susceptibility to the Infectious Salmon Anaemia Virus (ISAV) Using In Vivo Challenges

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Infectious salmon anaemia virus (ISAV) can cause disease and mortality in Atlantic salmon (Salmo salar). The virus is endemic in several regions including the Atlantic coast of Canada. Lumpfish (Cyclopterus lumpus) are increasingly utilised as cleaner fish to control sea lice levels in Atlantic salmon farms.

Movements of female lumpfish (Cyclopterus lumpus) around Iceland [PDF]

ICES Journal of Marine Science, 2014
Abstract Lumpfish (Cyclopterus lumpus) migrate from their offshore feeding areas to the coastal areas of Iceland during March and April where they remain for several months before spawning. Their movements during this time are poorly documented.

Safety evaluation of the food enzyme mannan endo‐1,4‐β‐mannosidase from the non‐genetically modified Aspergillus niger HBI‐GM01

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The food enzyme mannan endo‐1,4‐β‐mannosidase (1,4‐β‐d‐mannan mannanohydrolase; EC 3.2.1.78) is produced with the non‐genetically modified Aspergillus niger strain HBI‐GM01 by HBI Enzymes Inc. The food enzyme was considered free from viable cells of the production organism.
