Abstract

The paper attempts an evaluation of such climate fluctuations, as those of the Little Ice Age, from the point of view of historical data on carp culture. In the climate of Central Europe, carp growth is limited by temperature, especially in periods of unfavourable thermal conditions, and by water - in periods of drought. A tracing of the history of carp culture in the southern and western parts of Poland, where hydrological, climatic and geologi-cal conditions have been suitable for the development of fish farms, has made it possible to trace climate fluctuations since the Middle Ages onwards.

Keywords: ponds, carp growth, temperature, water balance
