Serum pigmentation in Cyclopterus lumpus L
Journal of Fish Biology, 1986Female lumpsuckers, Cyclopterus lumpus L., have blue‐green blood serum and subcutaneous gelatinous tissue; the male's are red/magenta in colour. The female serum contains a chromoprotein with biliverdin as the prosthetic group; the male serum contains the same biliverdin pigment but this is normally masked by a red pigment, probably phycoerythrin.

Characteristics of a proteinase from ovarian fluid of the lumpsucker (Cyclopterus Lumpus L.)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19881. A proteinase has been isolated from the ovarian fluid of the lumpsucker (Cyclopterus lumpus). 2. The enzyme was purified essentially to homogeneity by a one step purification procedure using anion-exchange chromatography. 3. The mol. wt of the denatured enzyme is approximately 20,000 as judged by SDS-polyacrylamide gel electrophoresis. 4. The enzyme

First estimates of age and production of lumpsucker (Cyclopterus lumpus) in Greenland
Fisheries Research, 2014Abstract Lumpsucker (Cyclopterus lumpus) spawn throughout the North Atlantic, and are fished prior to spawning for its valuable roe. This is also the case along most of the Greenland coast, and lumpsucker is of great economic importance throughout the country.

Pathogenicity of Pasteurella sp. in lumpsuckers (Cyclopterus lumpus L.)
Journal of Fish Diseases, 2018AbstractThe incidence of disease caused by Pasteurella sp. in farmed lumpsuckers in Norway has been steadily increasing in recent years, causing significant economic losses and fish welfare issues. The disease affects all life stages, both in hatcheries and after release into salmon cages. Therefore, it is important to establish robust challenge models,

Sucker action in the lumpsucker cyclopterusLumpusL.
Sarsia, 1990Attachment in the lumpsucker is initiated by the contraction of a horizontal pair of red muscles (I) running between the sucker skeleton and the hyoid arch.

Molecular immune responses of lumpfish (Cyclopterus lumpus) to aeromonas salmonicida
2023Lumpfish (Cyclopterus lumpus) have been utilized to biocontrol sea-lice (e.g., Lepeophtheirus salmonis) infestations in Atlantic salmon (Salmo salar) farms in the North Atlantic region. Aeromonas salmonicida subsp. salmonicida is a Gram-negative facultative intracellular pathogen infecting several fish species, including lumpfish.

Observations on the colours of lumpsuckers, Cyclopterus lumpus L.
Journal of Fish Biology, 1989Ripe unfertilized eggs derived from fish landed at two Icelandic ports were predominantly red and yellow‐red, but a small proportion were red‐purple. There was a significant difference between the frequencies of hues of eggs from the two landing places.

Pelagic records of the lumpsucker, Cyclopterus lumpus L.
Journal of Fish Biology, 1983Since the development of mid‐water trawls in the mid‐1960s, the lumpsucker, Cyclopterus lumpus, has been found to occur frequently in mid‐water. Records from cruises of English research vessels show that lumpsuckers occur pelagically from the southern North Sea to about 80°N off Spitsbergen, usually in the upper 50–60 m, and often over abyssal depths ...

The development of feeding behaviour in the lumpfish, Cyclopterus lumpus
Journal of Fish Biology, 1986This study concerned the development of feeding in larval lumpfish, Cyclopterus lumpus, and tested the hypothesis that these large, well‐developed larvae would not use typical ‘larval‐like’ modal action patterns (MAPs) in high frequency during early feeding.

Observations on the distribution of lumpsucker (Cyclopterus lumpus, L.) in the Norwegian Sea
Fisheries Research, 1993Abstract Catches of lumpsucker (Cyclopterus lumpus, L.) taken in late summer 1991 indicate that this species is widely distributed throughout the Norwegian Sea, with the largest concentrations occurring in the areas close to the polar front. The area may be an important nursery ground for Cyclopterus.
