Abstract
This report deals with any abnormal tissue, the growth of which exceeds and is uncoordinated with that of the normal tissue. Included in this category are the neoplasia (benign and cancerous), non‐functional hyperplasias, cellular hypertrophy as well as other atypical cell growths. The following topics are discussed with special reference to the temperate freshwater fishes of North America: papillomas, hyperplastic epidermal diseases (including fish pox), parasitic and neoplastic adenomas, carcinomas (incuding thyroid tumors), fibromas, fibro‐sarcomas, myxomas, leiomyomas, rhabdomyomas, granulomas, lymphosarcomas, pigment‐cell tumors, neurofibromas, neurilemmonas, hamartomas, and teratomas. The role of such factors as physical and chemical irritants, nutrition, endocrine dysfunction, heredity, embryonic disturbances, and such infectious agents as viruses, bacteria, mycotic organisms, and protozoans in the production of these abnormalities is given or suggested. With the exception of certain tumors, our knowledge concerning neoplasms in fishes in general is extremely limited, and very few contributions have been made by American fishery biologists. It is suggested that a greater effort be made to recognize these diseases, especially tumors which appear spontaneously in large populations of fishes.This publication has 0 references indexed in Scilit:
