PREPARATION OF THIS DOCUMENT

This document has been prepared to update CIFA/T7, 1980 a publication by the same name and the same author. In the process the entire text has been rewritten and the line illustrations supplemented with photographic material. The text was rewritten not only to accommodate new accumulated data and novel experiences, but also to accord with conceptual changes in our understanding of fish pathogens, their effects on fishes and new approaches to therapy and control resulting from scientific developments since 1980.

The information contained in the original publication, as well as this updated report, is a synthesis of the author's personal experience plus published data from a wide variety of sources, including personal communication and internal reports. All sources are acknowledged in the text. A special effort was made to compile all published information from Africa on aspects of fish health and, where relevant, also data on fish pathogens in warm waters outside Africa.

In the previous document a chapter was devoted to the human-health (epidemiological) risks associated with ponds as habitats for vectors of human diseases (malaria, schistosomiasis and arbor viruses). It was decided to exclude this aspect from the present document as it has received great attention since then in current scientific literature, and to discuss the subject adequately would have extended this publication beyond its prescribed framework.

ABSTRACT

This document complies and consolidates existing information on diseases and infections occurring in African fish. Data have been organised into a convenient format along with an update of available general information on fish diseases and their aetiological agents. Incorporated into the text are also relevant data and information on diseases found in species of African fish farmed outside Africa and general aspects of fish pathology relevant to warm water aquaculture. Information includes diagnostic aids (keys and illustrations) to assist in the recognition of disease agents, relevant data on their effects on fish, the way they are transmitted and where possible, suggestions for therapy and control. This document replaces a previous publication of the same name - CIFA/T7, 1980 by the same author.
