Clarifying much of the inconsistency currently encountered in the scientific literature, Histology and Histopathological Analysis of Endocrine Disruptive Effects on Small Laboratory Fish helps to standardize the interpretation of results from aquatic bioassays and field observations by describing basic biological function and contrasting normal histology with histopathological conditions in a variety of fish species. The authors represent the leaders of small fish gonadal histopathology, and they incorporate views and ideas from other experts.Timely title assembling the combined knowledge of some of the leading authorities in the field of small fish reproduction - an important topic for risk assessment and registration of chemical, agricultural, and pharmaceutical compounds Provides guidance on the microscopic structure of living tissue and evaluation of the reproductive glands of small laboratory fish Includes state-of-the-art science along with sufficient anatomical and physiological background for understanding and interpreting test results Helps standardize the interpretation of results from aquatic bioassays and field observations, which will also clarify inconsistencies in the current scientific literature Note: CD-ROM/DVD and other supplementary materials are not included as part of eBook file.
