You can download Diseases and Disorders of Finfish in Cage Culture 2nd Edition by Patrick T K Woo and David Bruno free in pdf format.
This new edition is a timely update on important advances in the understanding of infectious diseases of finfish. The content has been significantly updated to reflect current knowledge and the developments in the fish production industry, including the dramatic increases in production in the Asia-Pacific region. An important resource for aquaculturalists, fish health consultants and fish pathologists.
Finfish are an excellent source of protein and many marine species have beneficial PUFA (polyunsaturated fatty acids); however, the capture-fishery is either stagnant or in decline as there are no newly discovered fishing grounds. Also, natural fish stocks in many parts of the world have been significantly reduced due to more efficient fishing technologies, over and/or indiscriminate fishing, and the loss and/or destruction of spawning grounds. Industrial wastes (e.g. heavy metals, organophosphates) discharged into the aquatic environment can affect fish growth, survival and reproduction, and in some areas pollutants have accumulated in fish to the extent they are no longer suitable for human consumption. Cage culture of finfish (especially in-shore) has lower start-up and production costs and it does not have some of the problems associated with the raising of large numbers of warm blooded animals. Intensive culture of fish is one solution to producing more affordable animal protein; however, outbreaks of diseases may occur more frequently because of numerous factors, which include enhanced transmission of infectious pathogens between fish.
