Impact of thermoclines on the vertical distribution of salmon lice larvae
Salmon louse Lepeophtheirus salmonis, a key parasite of salmonids, is managed by multiple methods at both salmon farm- and ecosystem-scale that are informed by an understanding of the abundance and distribution of the infective, planktonic stage of the ...

The Disease Burden in Fish Farm Management: An Integrative View and a Specific Vision in Europe
ABSTRACT In aquaculture, the interactions and balance—or imbalance—between the fish, the rearing environment, pathogens, and farm management determine the occurrence and impact of clinical diseases. The global assessment of the factors related to disease impact is commonly referred to as disease burden.

ABSTRACT Atlantic salmon farming is faced with numerous environmental and production‐related challenges affecting fish health and welfare, globally and in Norway. An animal's requirement for a nutrient is the sum of the required supply of available nutrients for maintenance, growth, reproduction, health, and disease resistance.

Background The salmon louse, Lepeophtheirus salmonis, is an ectoparasitic copepod which feeds on the mucus, skin and blood of salmonid fish species. The parasite can persist on the surface of the fish without any effective control being exerted by the ...

Salmon Louse Infestation Impairs the Long‐Term Survival of Sea‐Run Brown Trout
Salmon louse (Lepeophtheirus salmonis) infestations significantly impair the survival of sea‐run brown trout (Salmo trutta), with a 73% reduction in survival probability per louse per gram of fish weight in 2020 and a 58% reduction in 2021. Our findings provide clear evidence of the long‐term ecological impacts of parasite burdens and underscore the ...

High resolution depth profile scanning of plankton organisms—VERTILICE
Knowledge of the vertical migration pattern of sea lice (Lepeophtheirus salmonis) copepodites is necessary for designing efficient measures to prevent lice infestations on farmed Atlantic salmon (Salmo Salar) in sea-cages.

Background The causal relation between parasitic sea lice on fish farms and sea lice on wild fish is a controversial subject. A specific scientific debate has been whether the statistical association between infestation pressure (IP) from fish farms and ...
