Lobsters
Description
Under the Editorship of Bruce Phillips an international team ofauthors provide exhaustive coverage of these fascinating creatures,stretching from growth and development to management andconservation, providing the reader with:
* Key information for lobster farmers and harvesters
* * Organisation of the species by genera for ease of use
* * Coverage of parasites, pathogens and commensals; their impact,detection and measurement
Fisheries scientists, aquaculture personnel, aquatic andinvertebrate biologists, physiologists, ecologists, marinebiologists and environmental biologists will all find this a vitalsource of reference. Libraries in universities and researchestablishments where biological and life sciences and fisheries andaquaculture are studied and taught will find it a valuable additionto their shelves.
