Predation Risk and Depth Use During Migration of Atlantic Salmon Smolts Through a Fjord Impacted by Hydropower Discharge

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Atlantic salmon (Salmo must survive the transition from river to fjord in order to migrate to northern latitudes where they feed and grow at sea. In the River Suldalslågen in southern Norway, hydropower regulated water discharge determines the timing and extent of river flows and fjord currents.

A Review of Nonsteroidal Anti‐Inflammatory Drugs for Food‐Producing Animals With a Focus on Potential Applications for Farmed Finfish

Journal of Fish Diseases, Volume 49, Issue 10, October 2026.
ABSTRACT In finfish aquaculture, there are several inflammatory diseases impacting productivity and animal welfare, however there are limited options available to veterinarians to treat inflammation and pain in fish. Nonsteroidal anti‐inflammatory drugs (NSAIDs) are widely used in terrestrial animals raised for human consumption to treat a range of ...

Navigating aquaculture health: Farm‐friendly framework for risk‐based management

Journal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract Risks to animal health are concerns for any agricultural system. Mitigation of these risks protects and improves population health and productivity, as well as opportunities for trade. Directing health management attention and resources to identify and address risk has the potential to achieve great impact for the least cost; however, risk ...

Comparing Drone and Vessel‐Based Imaging to Quantify Epibiont Coverage on Humpback Whales

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Cetacean epibionts offer noninvasive insights into host health, physiology, and spatial ecology, yet quantitative assessments in wild populations remain scarce. Although vessel‐based observations may be limited by field of view and analyst input, unoccupied aerial vehicles (UAVs; drones) are increasingly used to monitor cetacean health indices,

Infection strategies of fish ectoparasites [PDF]

, 1982
PhDCertain factors controlling the parasitic phase of some nonspecific fish ectoparasites were investigated. Studies were made of the infection patterns exhibited by the branchiuran Argulus foliaceus (L.

Comparative tests of ectoparasite species richness in seabirds [PDF]

, 2007
Background: The diversity of parasites attacking a host varies substantially among different host species. Understanding the factors that explain these patterns of parasite diversity is critical to identifying the ecological principles underlying ...

The impact of functional feed on Atlantic salmon (Salmo salar) systemic immune response to high and low levels of sea lice infection (Lepeophtheirus salmonis) and co-infection with infectious salmon anemia virus

Comparative Immunology Reports
Due to the nature of open-pen farming, salmon are exposed to numerous pathogens shared by other farms and their wild counterparts. Industry must manage these outbreaks through vaccination, oral or bath treatments, and more recently through functional ...

Modeling dynamics of adult female lice at salmon farming sites in Eastern Canada: a stochastic, state-based approach

Frontiers in Aquaculture
IntroductionSea lice are parasitic copepods that harm salmon health, reduce farm productivity, and create ecological and economic challenges for aquaculture.MethodsA stochastic, state-based, time-dependent epidemiological model was developed to ...

A gap analysis on modelling of sea lice infection pressure from salmonid farms. II. Identifying and ranking knowledge gaps: output of an international workshop

Aquaculture Environment Interactions
Sea lice are a major health hazard for farmed Atlantic salmon in Europe, and their impact is felt globally. Given the breadth of ongoing research in sea lice dispersal and population modelling, and focus on research-led adaptive management, we brought ...
