AbstractAbstract
[en] At the current rate of increase the world demand for fish protein will soon far exceed the supply. The culture of aquatic organisms in low-grade waste heat could be a significant source of animal protein. There are at present thriving trout culture and catfish culture industries in North America. There are a number of small-scale research and commercial aquaculture projects currently in operation and numerous studies have been carried out. However, the knowledge gained has not had a significant impact on waste heat aquaculture development. (author)

AbstractAbstract
[en] The impact of cooling water discharges from a 800 MW thermal power plant on four small eutrophic lakes in central Poland is described. Surface water layers in one lake became 8-11 deg C higher than normal. Surprisingly, oxygen content increased, probably due to mechanical agitation of the cooling water. Primary production increased in the heated lake for most aquatic species. (E.C.B.)

AbstractAbstract
[en] Heat from thermal discharges may find several uses in agriculture and particularly in the greenhouse industry. The most significant experiments done on the subject both in the United States and Canada are brifly reviewed and discussed. The current situation of the Canadian greenhouse industry is analysed and the possibility of greenhouse heating for making use of warm waste water is considered. It is concluded that the single use approach is of little value and consideration should rather be given to integrated agricultural systems to dissipate excess heat from power plant rejected waters.

AbstractAbstract
[en] Some limiting factors to the future development of freshwater aquaculture are considered. The most important of these are the need for new and improved technology for the production of better quality products at lower cost and for the promotion and establishment of new markets. The use of relatively small amounts of heated effluent water from power generating stations to optimize water temperatures is one feasible method for increasing growth and lowering the cost of production.

AbstractAbstract
[en] Effects of thermal effluents on the population dynamics of Physa gyrina Say (Gastropoda: Pulmonata) were studied at Lake Wabamun, Alberta, from May 1971 to August 1973. Thermal effluent increased the rate of development of eggs and the growth of P. gyrina, and allowed continuous reproductive activity throughout the year. These changes, and the increased period of growth of aquatic macrophytes, resulted in increased population densities of P. gyrina in the heated area during summer. Temperatures below 10 deg C or small amounts of vegetation appear to limit the population of P. gyrina in winter. (author)

AbstractAbstract
[en] Dependence of growth and reproduction of cultivated fishes on temperature are briefly reviewed. Experiments with and commercial-size operations of various methods of fish culture with the use of heated effluents are exemplified. Cage culture, earthen ponds, flowing water culture have demonstrated possibilities of growth increase in carp and rainbow trout and of controlled reproduction of the former. Problems involved in utilization of various systems and several points of view on the use of low-grade heat for fish culture are considered. (author)
