Aquaculture, 2018
Abstract Sea lice infestations causes major economic losses in the Atlantic salmon aquaculture industry, and cleaner fish, e.g. the lumpfish, Cyclopterus lumpus L., are therefore increasingly deployed as a biological control method. However, large variations in the cleaning efficacy have been observed, and in the Faroe Islands, the most prominent ...

Assessment of suitable substrates for lumpfish in sea pens
Aquaculture International, 2014This study assessed the use of different types of substrates for lumpfish in sea pens. Observations were recorded in the early morning before first light, and the number of lumpfish attached to each surface type was recorded. The substrate was removed and another design was deployed if no lumpfish were attached to a substrate for more than 2 weeks ...

Is cleaning behaviour in lumpfish (Cyclopterus lumpus) parentally controlled?
Aquaculture, 2016Abstract To investigate the possible family influence on sea lice grazing of lumpfish on Atlantic salmon, nine families of lumpfish (N = 360) with a mean (± SD) weight of 169.4 ± 8.3 g were distributed among nine sea cages (5 × 5 × 5 m) each stocked with 400 Atlantic salmon with a mean (± SD) weight of 123.3 ± 12.3 g.

Anaesthetic protocols for lumpfish (Cyclopterus lumpus L.)
Fish & Shellfish Immunology, 2016Lumpfish and different species of wrasse have shown to efficiently eat sea lice. Due to the high demand for cleaner fish, lumpfish is now farmed in Europe. In Norway, there has been a rapid increase in production sites the last three years and the number of produced lumpfish has increased from 0.4 million in 2012 to 10 million (estimate) in 2015. There

Phenodeviants of the Lumpfish Cyclopterus lumpus (Cyclopteridae) and Their Survival
Journal of Ichthyology, 2019Deviations in the development of the caudal peduncle in the lumpfish Cyclopterus lumpus are described. Data on abiotic and biotic conditions of lumpfish’s existence in the North Atlantic are generalized. The importance of a unique niche of lumpfish in the marine ecosystem, which allows fish with greatly reduced swimming abilities (functions) to survive,

An automated separator to exclude lumpfish with deformed suckers
BioShortsSalmon farming is threatened by sea lice infestations, which impact fish health, compromise welfare and reduce market value. The use of lumpfish as cleaner fish offers a natural solution for sea lice control, but the delousing efficacy of lumpfish can be hindered by morphological deformities, particularly in the ventral suckers (suction cups) of the ...

Osteological development of the lumpfish,inimicus japonicus (pisces: Synanceiidae)
Ichthyological Research, 1998The osteological development of the synanceiidInimicus japonicus, was described on the basis of five larvae and four juveniles (4.2–10.1 mm BL) reared in the laboratory, and two wild adult specimens. All bones, except for the basisphenoid, were formed in all larvae and juveniles, but fusions between the uppermost actinost and scapula, upper caudal ...

Genetic structure of West Greenland populations of lumpfish Cyclopterus lumpus
Journal of Fish Biology, 2016In this study, 11 microsatellite markers were used to determine the structure of West Greenlandic lumpfish Cyclopterus lumpus populations across six spawning locations spanning >1500 km and compared with neighbouring populations in Canada and Iceland. To evaluate whether data allow for identification of origin of C.

The Effects of Vertebral Deformities on Swimming Kinematics in Lumpfish, Cyclopterus lumpus
Integrative And Comparative BiologySynopsis Vertebral deformities such as abnormal curvatures and shapes may influence kinematics of fishes during swimming. Our study examines the vertebral deformities of hatchery-reared lumpfish (Cyclopterus lumpus) to better understand the effects of vertebral deformity on swimming kinematics.
