Salmon Lice

The salmon louse Lepeophtheirus salmonis is adapted to
survive in hostile marine environments of the northern hemisphere,
including an ability to parasitize several species of salmon.
Salmonids are some of the most economically important and
sought after fish for human consumption, and louse parasitism has a
significant impact both on cultured and wild fish populations.
Salmon Lice is a timely collection of the latest research on
the cause and spread of lice infestations and management techniques
being designed and implemented to combat this issue.

Salmon Lice provides a thorough single volume review of
Lepeophtheirus salmonis, the key parasite standing in the
way of sustainable and profitable production of salmonid fishes
including salmon, trout and charr. Opening with a review of the
biology, morphology, life cycle, and larval behavior of the
parasite, Salmon Lice proceeds to review the distribution of
planktonic larvae of salmon lice, addresses management techniques
used in salmonid aquaculture and capture fisheries, provides a
practical assessment of the salmon lice issue and explores
potential solutions to the problem.

With comprehensive coverage of the biology and distribution of
this harmful and ubiquitous parasite, Salmon Lice will be of
value to fish health researchers, aquaculture and fisheries
professionals, and seafood industry personnel to inform the
management of both cultured and wild salmonid populations.

Key Features:

• In-depth coverage of a key parasite impacting viability and
  sustainability of salmonid fisheries and aquaculture

• Integrates parasite biology and hydrodynamic models in diverse
  coastal ecosystems

• Provides a practical assessment of the salmon louse issue

Reviews international salmon louse monitoring and management
techniques used in salmonid fisheries and aquaculture
