Pollution as a Result of Fish Cultural Activities

Pages : 232
Book Description
Fish hatchery activities have been suspected as a source of pollution. This study was undertaken to evaluate this in hatchery discharges in relationship to possible pollution. A program of semi-monthly physical-chemical analysis was conducted for a year at six trout hatcheries. These determinations were taken at the hatchery inflow and outfall, the receiving water above and below the hatchery outfall. Bottom fauna was sampled once a month during the summer and bi-monthly through the winter on selected stations in the receiving waters. Flow data was recorded for the influent, effluent, and receiving waters. There was no correlation between the pounds of food fed in the hatcheries and: 1. changes of chemical quality in the receiving waters, 2. changes in kinds and numbers of bottom fauna organisms in the receiving waters. The analysis of samples revealed degradation of the water quality through every hatchery and in the receiving water. This degradation was beneficial from a fisheries standpoint but water quality and public health considerations may require cleanup before acceptable levels could be achieved. This report was submitted in fulfillment of grant no. 18050 EDH between the Environmental Protection Agency and Utah Division of Wildlife Resources.

Book Description
Indexes material from conference proceedings and hard-to-find documents, in addition to journal articles. Over 1,000 journals are indexed and literature published from 1981 to the present is covered. Topics in pollution and its management are extensively covered from the standpoints of atmosphere, emissions, mathematical models, effects on people and animals, and environmental action. Major areas of coverage include: air pollution, marine pollution, freshwater pollution, sewage and wastewater treatment, waste management, land pollution, toxicology and health, noise, and radiation.
