Changes in Lepeophtheirus salmonis gene expression during host switching and selection

open access: yes, 2014
Lepeophtheirus salmonis is a copepod parasite of salmonid fish, commonly referred to as sea lice, and is particularly pathogenic to Atlantic salmon (Salmo salar). Although endemic on wild salmon, L.

Monitoring effectiveness of emamectin benzoate for the treatment of sea lice (Lepeophtheirus salmonis) on farmed Atlantic salmon (Salmo salar)

open access: yes, 2012
Resistance development to parasiticides has been a problem in both terrestrial and aquatic environments. A major challenge exists in early detection of resistance emergence due to the low frequency at which resistant organisms can occur initially within ...

Monitoring parasitic abundance in cage-based aquaculture : the effects of clustering [PDF]

open access: yes, 2006
Most discussions of sampling protocols within the literature on monitoring aquatic parasites are based on the assumptions of simple random sampling. There has been a growing recognition within the fields of human and terrestrial veterinary epidemiology ...

Analysis of a short tail type in farmed Atlantic salmon (Salmo salar) [PDF]

open access: yes, 2005
The short tail phenotype represents one of the main causes for downgrading of farmed Atlantic salmon (Salmo salar) at slaughterhouses. Prevalence of short tail is variable and the aetiology is suspected to be multi-factorial.

Temperature-driven suitability shifts of sea lice species under climate change and the implications for salmon farming

open access: yesAquaculture Environment Interactions
Salmonids are the most valuable marine aquaculture family, worth approximately US$26.2 billion in 2022. However, the industry’s economic value is threatened by sea lice infestations, which can cause production losses and require expensive treatments to ...

Semigroup analysis of structured populations with distributed states-at-birth arising in mathematical aquaculture [PDF]

open access: yes, 2009
Motivated by the modelling of structured parasite populations in aquaculture we consider a class of physiologically structured population models, where individuals may be recruited into the population at different sizes in general. That is, we consider a
