Buoyancy in the LumpsuckerCyclopterus Lumpus
Journal of the Marine Biological Association of the United Kingdom, 1986The lumpsucker or lumpfish,Cyclopterus lumpusL. (Cyclopteridae, Scorpaeniformes), is a cottoid teleost, and, like other fish in its family, exhibits many characteristics of a coastal, bottom-dwelling fish. It is globiform, has no swimbladder, possesses a large abdominal sucker (formed from the pelvic fins), and lays demersal eggs which are brooded by ...

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.

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

Genetic population structure and demographic history of a pelagic lumpsucker, Aptocyclus ventricosus
Environmental Biology of Fishes, 2020The population structure and demographic history of a pelagic lumpsucker, Aptocyclus ventricosus, were investigated on the basis of sequence variation in the mitochondrial cytochrome b gene (1038 bp). The haplotype network clearly recovered two haplotype groups, consisting of western and eastern North Pacific individuals, except for some specimens ...

The lumpsucker, Cyclopterus lumpus, a cottoid teleost fish found in the cold waters of the North Atlantic, and North Pacific, was identified as a possible source of GAGs. The GAGs present in the C. lumpus dorsal hump and body wall tissue were isolated and purified.

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.

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.

Movements of lumpsucker females in a northern Norwegian fjord during the spawning season
Environmental Biology of Fishes, 2011The lumpsucker Cyclopterus lumpus is distributed throughout the North Atlantic Ocean and migrates considerable distances between offshore feeding areas and shallow inshore spawning grounds. The number of the lumpsucker has declined since the mid 1980s, probably as a result of overexploitation.

Journal of Ichthyology, 2019
The species status is justified for the Okhotsk lumpsucker Eumicrotremus ochotonensis based on the morphological characters. The differences from the closely related species E. derjugini inhabiting the Arctic Ocean are given. Two species were redescribed basing on type series, their diagnoses were clarified, and the lectotypes were designated ...

C-reactive protein-like precipitins in lumpsucker (Cyclopterus lumpus L.) gametes
Experientia, 1976A precipitin to pneumococcal and fungal C-substance, found in both ova and spermatozoa from a marine teleost fish, has similarities to mammalian C-reactive protein (CRP). This is the first demonstration of a CRP-like protein in the gametes of any species and adds further interest to the as yet unknown physiological role of CRP in vertebrates.
