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.

Tolerance of juvenile lumpfish (Cyclopterus Lumpus) to high rearing densities

Journal of the World Aquaculture Society
Lumpfish (Cyclopterus lumpus) are raised as cleaner fish for controlling sea lice. Intensive rearing is complicated by fin nipping that occurs between juvenile conspecifics.

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.

Growth performance, fast muscle development and chemical composition of juvenile lumpfish (Cyclopterus lumpus) fed diets incorporating soy and pea protein concentrates

Aquaculture Reports, 2020
Lumpfish (Cyclopterus lumpus) are widely applied as biological delousers in open net-pen farming of Atlantic salmon. As a species new to farming it is necessary to obtain a comprehensive understanding of the capacity of lumpfish to utilize plant derived ...

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.

Condition factor tailored to lumpfish (Cyclopterus lumpus) used as cleaner fish in salmonid farms

Aquaculture Reports
Lumpfish (Cyclopterus lumpus) are extensively used as part of the control measures against salmon lice in fish farms. In recent years, there has been an increased focus on lumpfish welfare, and how to increase survival of lumpfish during production.

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

Enzymatic hydrolysis of lumpfish (Cyclopterus lumpus) meat: effect of enzyme selection on protein recovery and hydrolysate properties for side-stream valorization

Frontiers in Sustainable Food Systems
IntroductionLumpfish (Cyclopterus lumpus) is a commercially important fish species, valued for its roe and its application as a cleaner fish in salmon farming. Wild caught lumpfish are primarily harvested for the roe. The rest of the carcass is generally

Fish welfare based classification method of ocean current speeds at aquaculture sites

Aquaculture Environment Interactions, 2019
A major trend in marine aquaculture is to move production to more exposed sites with occasionally rough ocean current events. However, it is unclear whether fish will thrive in these extreme environments, since thorough descriptions of ambient current ...
