Heating an Aquaculture pond with a curved floating collector

Abstract

Fishes are affected by low temperatures of water in winter months, that causes a decrease in reproduction rate and in aquaculture production. Tests were carried out in two ponds models; floating collectors were placed in the first one and the second one worked as a reference sample. Looking to moderate temperature decrease, floating collectors with acetate-curved cover were tested. The experiences were carried out under NEA climatic conditions during winter. A good performance was obtained from floating collector in reference to the increase in temperature wanted. Differences of temperatures are presented between two ponds models. There in addition to other climatic parameters. During July, it was obtained a temperature increase of 6,2 °C and in August, the increase was 8 °C between water and atmosphere temperature.
