Causes of Mortality and Loss of Lumpfish Cyclopterus lumpus [PDF]
Fishes, 2022 Data from research and commercial use of lumpfish were collected from the research facilities of Gifas (Inndyr, Northern Norway, 67.0° N, 14.0° E). The data were sourced from 12 main lumpfish groups subdivided into 66 subgroups (N = 160,729) delivered to

In lumpfish We Trust? The Efficacy of Lumpfish Cyclopterus lumpus to Control Lepeophtheirus salmonis Infestations on Farmed Atlantic Salmon: A Review [PDF]
Fishes, 2022 In this review, we have systematized current knowledge about the effect of stocking lumpfish (Cyclopterus lumpus) as cleaner fish to control Lepeophtheirus salmonis infestations on farmed Atlantic salmon (Salmo salar L.).

Condition factor tailored to lumpfish (Cyclopterus lumpus) used as cleaner fish in salmonid farms [PDF]
Aquaculture ReportsLumpfish (Cyclopterus lumpus) are extensively used as part of the control measures against salmon lice in fish farms. In recent years, there has been an increased focus on lumpfish welfare, and how to increase survival of lumpfish during production.

Tolerance of juvenile lumpfish (Cyclopterus Lumpus) to high rearing densities
Journal of the World Aquaculture SocietyLumpfish (Cyclopterus lumpus) are raised as cleaner fish for controlling sea lice. Intensive rearing is complicated by fin nipping that occurs between juvenile conspecifics.

Ultrasonic imaging as a means of monitoring gonadal development in lumpfish (Cyclopterus lumpus) [PDF]
Physiological Reports, 2023 The commercial farming of juvenile lumpfish requires monitoring of gonadal development to achieve synchronized production. Conventional methods such as gonadosomatic index (GSI), sex hormone analyses, gonadal histology, endoscopy, and gene expression ...

Addressing the welfare needs of farmed lumpfish: Knowledge gaps, challenges and solutions [PDF]
Reviews in Aquaculture, 2021 AbstractLumpfish (Cyclopterus lumpusL.) are increasingly being used as cleaner fish to control parasitic sea lice, one of the most important threats to salmon farming. However, lumpfish cannot survive feeding solely on sea lice, and their mortality in salmon net‐pens can be high, which has welfare, ethical and economic implications.

Delousing performance of ballan wrasse (Labrus bergylta) and lumpfish (Cyclopterus lumpus): seasonal consistency and the challenge of cryptic lice for lumpfish. [PDF]
Pest Manag SciCleaner fish play a crucial role in controlling caligid sea lice in Atlantic salmon aquaculture across the North Atlantic. However, their delousing performance varies due to multiple factors, including water temperature and cleaner fish size. Anecdotal reports of less-pigmented sea lice have raised concerns that these variants may emerge as a response ...

Physiological Effects of Recapture and Transport from Net-Cages in Lumpfish
Fishes, 2022 Lumpfish are widely used for removing sea lice in salmonid sea-based aquaculture. If these fish are to be harvested and used for human consumption, it is necessary to know how the physical strain associated with removing the lumpfish from the net-cages ...

It works! Lumpfish can significantly lower sea lice infestation in large-scale salmon farming
Biology Open, 2018 To assess the efficacy of lumpfish grazing on attached sea lice on Atlantic salmon, six large-scale sea cages, (130 m circumference, 37,688 m3 volume) each stocked with approximately 200,000 salmon 0+ smolts, were stocked with a 4, 6 and 8% density (8000,

Transcriptome-wide analyses of early immune responses in lumpfish leukocytes upon stimulation with poly(I:C) [PDF]
Frontiers in Immunology, 2023 BackgroundBoth bacterial and viral diseases are a major threat to farmed fish. As the antiviral immune mechanisms in lumpfish (Cyclopterus lumpus L.) are poorly understood, lumpfish leukocytes were stimulated with poly(I:C), a synthetic analog of double ...
