The title of this paperback should be "The Treatment and Control of Parasites of Freshwater Fishes," since a therapeutic armamentarium is its chief feature. This information, which was collected from many, often obscure, sources, is the most comprehensive collection of data on the subject that has ever been assembled and published. As pointed out by Drs. Hoffman and Meyer, two outstanding authorities on fish diseases, the efficacy of many of the chemicals listed has not been critically evaluated, and some of them should be used with caution. To this end, they have included a table which gives the toxicity limits for some of the common chemicals used for the control of fish parasites. Also included are tables of conversion units and guides for the determination of quantities of chemicals needed to yield desired concentrations, a synopsis of the most widely used therapy and control measures, and 106 color photographs of common fungal, protozoan, and metazoan parasites that are the main causes of disease and death of fishes in hatcheries, rearing ponds, or in home and public aquaria all over the world. Parasites of Freshwater Fishes will be widely used by fish culturists and aquarists in the management of disease problems.
