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

Evaluation of the protective efficiency of an autogenous Vibrio anguillarum vaccine in lumpfish (Cyclopterus lumpus) under controlled and field conditions in Atlantic Canada

Frontiers in Aquaculture, 2023
Lumpfish (Cyclopterus lumpus) have become the predominant cleaner fish species used in North American salmon aquaculture. Vibrio anguillarum is a frequent pathogen of lumpfish in Atlantic Canada, and current vaccines against local isolates conferred low ...

Development of an Accurate Polymerase Chain Reaction (PCR) Assay for Genetic Sex Identification in Lumpfish (Cyclopterus lumpus) Based on Male-Specific Anti-Mullerian Hormone (amh) Gene

Fishes, 2023
The production of lumpfish (Cyclopterus lumpus) has become crucial in controlling sea lice levels in salmonid aquaculture. To improve their breeding, there is a need for early sex identification.

Transcriptome-wide analyses of early immune responses in lumpfish leukocytes upon stimulation with poly(I:C)

Frontiers in Immunology, 2023
BackgroundBoth bacterial and viral diseases are a major threat to farmed fish. As the antiviral immune mechanisms in lumpfish (Cyclopterus lumpus L.) are poorly understood, lumpfish leukocytes were stimulated with poly(I:C), a synthetic analog of double ...

Morphological characteristics of South Baltic lumpfish, Cyclopterus lumpus L., 1758 [PDF]

Acta Ichthyologica et Piscatoria, 2000
Morphological characteristic of lumpfish caught in the spring of 1995 in coastal waters of the Southern Baltic Sea near Unieście and Chłopy have been outlined in this paper. In total 140 fish were used for measurements. The analysis of countable features

Pelagic Larval Duration and Isolation by Distance in Coastal Species. [PDF]

Evol Appl
ABSTRACT Dispersal among populations is crucial both for demographic stability and for the evolutionary potential of species. In marine organisms, dispersal has been shown to be prevalent during pelagic early life stages. Consequently, pelagic larval duration (PLD) has been proposed as an important driver of gene flow in marine species and is ...

Shelters can negatively affect growth and welfare in lumpfish if feed is delivered continuously [PDF]

PeerJ, 2018
Due to the socioeconomic importance of salmon farming in the North Atlantic and the economic impact of sea lice in this industry, there is high demand for novel pest control methods.

Causes of Mortality and Loss of Lumpfish Cyclopterus lumpus

Fishes, 2022
Data from research and commercial use of lumpfish were collected from the research facilities of Gifas (Inndyr, Northern Norway, 67.0° N, 14.0° E). The data were sourced from 12 main lumpfish groups subdivided into 66 subgroups (N = 160,729) delivered to

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response

Journal of Fish Biology, EarlyView.
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

Biofluorescence in polar zoarcid eelpouts: The Arctic eelpout Lycodes reticulatus (Reinhardt, 1835) and the Antarctic eelpout Pachycara brachycephalum (Pappenheim, 1912)

Journal of Fish Biology, EarlyView.
Abstract Biofluorescence is widespread among marine fish but remains poorly documented in polar ecosystems. Using hyperspectral imaging, we report fluorescent emissions in two polar zoarcid eelpouts. A captive Antarctic eelpout (Pachycara brachycephalum) displayed uniform bright green fluorescence (~500–520 nm), whereas an Arctic eelpout (Lycodes ...
