Journal of Applied Aquaculture, 1999
ABSTRACT An inexpensive, low maintenance light-trap was developed for use in determining the distribution and abundance of marine larvae in regions where conventional methods may not be used. The light trap was a portable system (0.021 m3 total volume) designed to attract positively phototropic animals to a small region of strongest illumination, from ...

Development of vaccines against sea lice
Pest Management Science, 2002AbstractA review of efforts to develop a vaccine against sea lice is presented together with analysis of the rationale behind the approaches and potential future directions. Vaccines against the caligid copepod, Lepeophtheirus salmonis, have the potential to be a cost‐effective means of controlling the infection and avoid many of the disadvantages of ...

Sea lice or subsistence? Peasant multispecies justice in the plantationocene
Environment and Planning E Nature and SpaceSea lice pose serious problems for the fish farming industry, subsistence livelihoods, ecosystem health, and multispecies flourishing. This ethnographic essay examines the reaction of subsistence fishers on Guatemala's Pacific coast to a sea lice ...

Pest Management Science, 2002
AbstractSea louse (Family Caligidae: genera Caligus and Lepeophtheirus) infection of farmed salmonids represents a significant threat to animal welfare and undermines profitability. Lice may also act as vectors for the transmission of viral and bacterial pathogens.

Sea-lice infection models for fishes
Journal of Mathematical Biology, 2008As free-living sea-lice larvae are difficult to sample directly, lice abundances on fish have recently been used to study larvae in the water. In the KLV problem, juvenile wild salmon migrate past a salmon farm, and the change of infection with distance along the migration route is used to estimate larvae production from the farm.

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.
