James R. J Wildl Dis 1 July ; 54 3 : — This new book entitled Fish Diseases: Prevention and Control Strategies is edited by Galina Jeney and includes 10 chapters written by a varied but excellent group of international authors.

When fish are living under less than optimal conditions, their resistance to disease is reduced, and they may be infected by common diseases that are often present in the environment at low levels. For this reason, it is very important to make sure that we do all that we can to ensure a good environment for our aquatic animals and protect them from the introduction of exotic diseases.
