Species used as indicator organisms for monitoring programs are best selected from those known to be susceptible to epizootics of neoplasms. Lesions which can be quickly located and preserved in the field and for which a data base exists to help interpretation include liver neoplasms and external neoplasms. Since tumor frequencies increase with age and may change from season to season, studies should hold these variables constant among locations. During the design of the study investigators should determine the number of fish they need to examine in order to achieve the degree of resolution desired. Finally the field crew must be familiar with fish anatomy and necropsy techniques as well as storage and handling of the chosen preservative.
