C-reactive protein-like precipitins in lumpsucker (Cyclopterus lumpus L.) gametes

Experientia, 1976
A 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.

Sucker action in the lumpsucker cyclopterusLumpusL.

Sarsia, 1990
Attachment 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.

Characteristics of a proteinase from ovarian fluid of the lumpsucker (Cyclopterus Lumpus L.)

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1988
1. 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

Observations on the colours of lumpsuckers, Cyclopterus lumpus L.

Journal of Fish Biology, 1989
Ripe 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.

Characterisation of hyaluronic acid and chondroitin/dermatan sulfate from the lumpsucker fish, C. lumpus

Carbohydrate Polymers, 2014
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.

Pelagic records of the lumpsucker, Cyclopterus lumpus L.

Journal of Fish Biology, 1983
Since 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 ...

Movements of lumpsucker females in a northern Norwegian fjord during the spawning season

Environmental Biology of Fishes, 2011
The 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.

Age-reading of lumpsucker (Cyclopterus lumpus) otoliths: dissection, interpretation and comparison with length frequencies

Fisheries Research, 2002
This paper describes the use of lumpsucker (Cyclopterus lumpus) otoliths for age determination, with focus on methods that were found practical, the precision achieved in the first documented age-reading workshop of this species, and comparisons with length composition of the stock.

Observations on the distribution of lumpsucker (Cyclopterus lumpus, L.) in the Norwegian Sea

Fisheries Research, 1993
Abstract 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.
