Beyond spring season: An autumn observation of adult lumpsuckers (Cyclopterus lumpus) in coastal Norway Frøya archipelago raises questions on extended spawning activity

Journal of Fish Biology, Volume 108, Issue 6, Page 2211-2215, June 2026.
Abstract During snorkelling near Frøya, central Norway, on 6 October 2025, a pair of adult lumpsuckers (Cyclopterus lumpus) was observed engaged in apparent prespawning behaviour in shallow kelp habitat. Such activity is surprising, as the species is mainly considered a spring spawner throughout the eastern Atlantic and is the focus of a targeted ...

Use of lumpfish for sea‐lice control in salmon farming: challenges and opportunities [PDF]

Reviews in Aquaculture, 2017
AbstractEfficient sea‐lice control remains one of the most important challenges for the salmon farming industry. The use of wrasse (Labridae) as cleaner fish offers an alternative to medicines for sea‐lice control, but wrasse tend to become inactive in winter.

The Deep‐Sea Preyscapes of Mammalian Top Predators

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Deep‐sea predator foraging is shaped by prey richness, accessibility, and density. Using eDNA and acoustics, we mapped fish and cephalopod communities across inshore‐offshore gradients around the Azores in foraging habitats of three co‐occurring deep‐diving toothed whales.

Development of anaesthetic protocols for lumpfish (Cyclopterus lumpus L.): Effect of anaesthetic concentrations, sea water temperature and body weight. [PDF]

PLoS ONE, 2017
In recent years, use of lumpfish (Cyclopterus lumpus L.) as cleaner-fish to remove sea-lice have been chosen by many salmon farmers in Europe and Canada as an alternative to medical treatment, which has led to large scale production of lumpfish.

Comparison of Environmental DNA Metabarcoding and Trawl Data Highlights Gear Selectivity of Marine Demersal Fish Surveys on the Faroese Plateau

Environmental DNA, Volume 8, Issue 2, March/April 2026.
The study compared trawl and eDNA metabarcoding of demersal fish communities in an open ocean environment around the Faroe Islands. eDNA provided a comparable assessment of demersal species biomass and revealed additional spatial information on keystone species known to be under‐sampled by demersal trawls due to size and behavioral traits.

The use of photoperiods to provide year round spawning in lumpfish Cyclopterus lumpus [PDF]

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2019
In order to provide year round spawning broodstock, lumpfish (initial size 746 g and 24.9 cm) were reared under four different photoperiod regimes from January 2017 to July 2018. One group was reared under simulated natural photoperiod (LDN, control group) for Tromsø (70°N).

Marine Mammals in the Anthropocene: Developing a Systematic Evidence Base of Threats to Nineteen Species

Mammal Review, Volume 56, Issue 1, March 2026.
Marine mammals are vulnerable to a variety of anthropogenic threats, yet a global systematic map of the literature for 19 species found both spatial and temporal disparity in research effort between threats and between species. There are knowledge gaps for species and threats, with effort unequal across many species' ranges.

Welfare Indicators for Aquaculture Research: Toolboxes for Five Farmed European Fish Species

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Refining approaches to measuring, monitoring and appraising animal welfare in aquaculture research is key to (i) protecting and optimizing it, (ii) documenting the severity of how and when it deviates, and (iii) ensuring good scientific quality, reliable results and reproducibility, amongst other factors.

Practical Diets Formulated With Different Plant‐Based Energy Ingredients Modulate Nutrient Utilization and Gut Morphology in Tambaqui (Colossoma macropomum)

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Despite the increasing use of plant‐based energy ingredients in aquaculture, few studies have evaluated the digestibility of practical diets formulated with these ingredients in an integrated manner with the metabolic responses, intestinal health, and productive performance of fish. This limits the understanding of their nutritional effects. This study

Pharmacokinetic Data Show That Oxolinic Acid and Flumequine Are Absorbed and Excreted Rapidly From Plasma and Tissues of Lumpfish

Frontiers in Veterinary Science, 2019
This study examined the uptake, tissue distribution and elimination of the antibacterial agents oxolinic acid and flumequine in lumpfish (Cyclopterus lumpus L.) by use of LC-MS/MS following a single oral administration of 25 mg/kg fish given in feed ...
