Available in PDF, EPUB and Kindle. Book excerpt: The toxicity of chloramine-T, a therapeutant used to treat bacterial gill disease in fish, was evaluated under a variety of physical and chemical conditions. Chloramine-T was more toxic in warm water than in cold water at exposures of 24 hour or less, but temperature had no significant effect on toxicity in 96-hour exposures. The chemical was slightly less toxic to rainbow trout in hard than in soft water, but water hardness had little influence on its toxicity to channel catfish. The pH was the most important factor affecting chloramine-T toxicity; the chemical about 6 times more toxic at pH 6.5 than at 9.5.

This book was released on 1988 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chloramine-T is effective for the control of bacterial gill disease in fishes but data on its toxicity and safety are lacking. The effect of fish loading rates, feed levels, and fecal material on the availability and toxicity of the chemical was examined. Its toxicity increased as loading rates of fathead minnows increased from 0.52 to 2.07 g/L of water. The presence of fish fod decreased the toxicity of the chemical. The presence of fecal material also significantly decreased the toxicity of chloramine-T. Concentrations in water decreased more rapidly when fish were present than when only feed or fecal matter was present. The decreases were greatest in the presence of fish, feed, and fecal matter.

This book was released on 2019-06-07 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A remarkable accomplishment.... [This volume] has been and will continue to be a major force advancing freshwater fish parasitology."—Ernest H. Williams Jr., from the ForewordThis thoroughly revised and updated edition of a classic reference work is the definitive guide to the identification of the parasites of freshwater fishes of North America. The book provides information on public health concerns about fish parasites, the methods used to examine fish for parasites, and those parasites found only in very selective organs or tissues. It lists the known species of each genus, along with reference citations that enable readers to find literature pertinent to species identification, life cycles, and in some cases, control. In the heart of the book, each chapter opens with a description of a phylum and its relevant families and genera, followed by a species list for those genera. Drawings illustrate a representative of each genus, and are supplemented by photographic examples.Many new parasites of North American freshwater fishes have been discovered since the publication of the first edition thirty years ago. For this new edition, the author has added new species accounts and revised the taxonomy, expanded descriptions and discussion of the most important fish parasites, provided a glossary to aid nonspecialists, and updated the reference list through 1992. The volume features twice as many illustrations as the first edition, including the addition of 33 color photographs.
