Solar greenhouse aquaculture : [manuscript]

Solar greenhouse aquaculture : [manuscript]

Item consists of an offprint of the paper "Solar greenhouse aquaculture", written by W. van Toever of the Ark Project, originally published in "Solar Energy: Bringing it down to Earth: The Proceedings of the Solar Energy Society of Canada Inc., 1979 National Conference".

Abstract: "Rainbow and Speckled Trout have been successfully hatched and reared in a recirculating aquaculture system. The system is integrated into the Ark greenhouse providing thermal mass for temperature regulation and supplying nutrient-rich water for plants. The system incorporates bacterial, algal and hydroponic water filtration. Various vegetable crops have been raised in the hydroponic troughs. A scaled-down system suitable for domestic solar greenhouse application is also under development."
