Sea‐Cage Aquaculture, Sea Lice, and Declines of Wild Fish
Conservation Biology, 2009Abstract: A sea cage, sometimes referred to as a net pen, is an enclosure designed to prevent farm fish from escaping and to protect them from large predators, while allowing a free flow of water through the cage to carry away waste.

Environmental policy and innovation in Norwegian fish farming: Resolving the sea lice problem?
Marine Policy, 2020 Abstract In Norway, the world's largest salmon-producing country, reducing sea-lice levels in fish farms has been an overarching goal of government policy since 2013. However, industry innovation has not yet succeeded in significantly reducing the sea lice problem. We identify two main types of radical environmental innovation that could potentially

Pest Management Science, 2002
AbstractThere are many examples of successful biological control of pest populations in aquatic environments. This approach to sea louse control has environmental benefits and is cost‐effective. The range of possible pathogens of lice is reviewed and epibionts recorded from sea lice, including the monogenean Udonella caligorum and ciliates, are ...

Ecology of sea lice parasitic on farmed and wild fish
Trends in Parasitology, 2006Sea lice, especially Lepeophtheirus salmonis and Caligus spp., have the greatest economic impact of any parasite in salmonid fish farming and are also a threat to wild salmonids. Here, I review how the biology and ecology of various louse and host species influence their pathogenicity and epidemiology.

Fish immune responses to parasitic copepod (namely sea lice) infection
Developmental & Comparative Immunology, 2014Parasitic copepods, in particular sea lice, have considerable impacts upon global freshwater and marine fisheries, with major economic consequences recognized primarily in aquaculture. Sea lice have been a contentious issue with regards to interactions between farmed and wild populations of fish, in particular salmonids, and their potential for ...

Effect of cleaner fish on sea lice in Norwegian salmon aquaculture: a national scale data analysis
International Journal for Parasitology, 2020The salmon aquaculture industry has adopted the use of invertivorous 'cleaner fishes' (CF) for biological control of sea louse infestations on farmed salmon. At present, ~50 million CF are used annually in Norway alone, with variable success in experimental and industrial contexts. We used a national scale database of louse counts, delousing treatments

The Use of Lufenuron to Treat Fish Lice (Argulus sp) in Koi (Cyprinus carpio)
Journal of Exotic Pet Medicine, 2013Abstract Fish lice can cause significant morbidity and death in heavily infested fish. In addition to being a mechanical irritant when sucking blood, Argulus sp have been shown to be the vector for other fish diseases. Koi carp from a pond environment were presented with multiple raised dark spots on their dorsa and sides.

Fish Lice (Argulus japonicus) in Goldfish (Carassius auratus).
Comparative medicine, 2016Fish lice (Argulus spp; family Argulidae) are branchiuran crustaceans that parasitize both marine and freshwater fishes. Argulus spp can be a major threat to fish health, because heavy infestations can cause significant morbidity and mortality. In addition, fish lice are known to be the vehicle for other fish diseases.

Sea lice, sockeye salmon, and foraging competition: lousy fish are lousy competitors
Canadian Journal of Fisheries and Aquatic Sciences, 2015Pathogens threaten wildlife globally, but these impacts are not restricted to direct mortality from disease. For fish, which experience periods of extremely high mortality during their early life history, infections may primarily influence population dynamics and conservation through indirect effects on ecological processes such as competition and ...
