Ova lipid profiling and egg quality in wild and captive lumpfish, Cyclopterus lumpus (Linnaeus, 1758) [PDF]

, 2022
Lumpfish (Cyclopterus lumpus) serves an important role as cleaner fish for removing salmon lice in salmon aquaculture. For this use, cultivated lumpfish are preferred over wild-caught fish to avoid overexploitation of natural stocks and provide a stable ...

Lumpfish Cyclopterus lumpus reproduction: Pituitary gene expression, physiological and morphological changes accompanying gonadal maturation

Aquaculture, 2023
Lumpfish is the most important cleanerfish species in Atlantic salmon farming. Detailed information on the gonadal maturation process is a prerequisite for year-round production of juvenile lumpfish. In the present study we have described physiological, morphological and endocrine events associated with the annual reproductive cycle in lumpfish of both

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.

Anaesthesia of Lumpfish (Cyclopterus lumpus) fries. v1 [PDF]

, 2018
Large numbers of lumpfish are produced for the Norwegian salmon industry and are used to combat sea lice infestations. The present work tested the efficacy of three anaesthetic chemicals on lumpfish fries (average weight of 0.97 g).

The use of photoperiods to provide year round spawning in lumpfish Cyclopterus lumpus [PDF]

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2019
In order to provide year round spawning broodstock, lumpfish (initial size 746 g and 24.9 cm) were reared under four different photoperiod regimes from January 2017 to July 2018. One group was reared under simulated natural photoperiod (LDN, control group) for Tromsø (70°N).

Evolutionary, comparative, and functional analyses of STATs and regulation of the JAK-STAT pathway in lumpfish upon bacterial and poly(I:C) exposure

Frontiers in Cellular and Infection Microbiology, 2023
BackgroundThe Janus kinase/signal transducers and activators of transcription (JAK-STAT) system regulates several biological processes by affecting transcription of genes as a response to cytokines and growth factors.

Looming-eyes buoys fail to reduce seabird bycatch in the Icelandic lumpfish fishery: depth-based fishing restrictions are an alternative

Royal Society Open Science, 2023
Bycatch in gillnets from lumpfish (Cyclopterus lumpus) fisheries is an important conservation issue in the north Atlantic, with up to 30 000 seabirds potentially killed each year. To date, no technical solutions exist to reduce the bycatch of seabirds in

Effect of incubation temperature on eggs and larvae of lumpfish (Cyclopterus lumpus) [PDF]

Aquaculture, 2019
Abstract Two batches of lumpfish eggs were incubated at three temperature regimes; 1-Ambient seawater 4–6 °C (cold), 2-Ambient seawater for 10 days followed by a gradual increase to 10 °C (gradient), 3-Constant 10 °C seawater (warm). The eggs incubated in cold water had the highest egg mortality (38.5% ± 15.7) and lowest hatching success (46.1% ± 7.2)
