Aquafarms are usually located in remote tidal channels, and over 90% do not have access to grid connected power. At present, diesel generators are the most common source, with some farms having small hydro systems or no power at all. A 12v dc solar power system was designed to deliver a minimum of 600 watt hours per day using a 630 peak watt photovoltaic array of 14 45w modules, 1540 amp-hrs of battery storage, a 50 amp series relay regulator and a 1.2 kW inverter to provide 120v ac power. The prototype system was installed at the Goodrich Island Seafarms' Sooke Basin site located 50 km west of Victoria in December 1986. Insolation and dc power consumption were monitored for 6 months, from January 27-June 1, 1987. This report summarizes the development of the system, the monitoring program at the farm, and the economics of solar energy systems for the aquafarming industry.

The need and demand for fish and seafood are rising continually worldwide, and wild fish stocks are steadily becoming scarcer and scarcer. Aquaculture is a young and innovative part of the economy with high growth rates and secured prospects. The future of fish production requires that water be used as economically as possible, and that waste products be removed safely with the lowest possible energy consumption. Environmental legislation is progressively reducing the possibilities of open water fish production and existing fish farms are confronted with directives for purifying their waste discharges. This has acellerated the development of intensive, water-saving Systems for fish production, which do not depend upon natural environmental factors. Production in closed water Systems offers a more compact growing Environment for the fish, lower shared personnel costs and the potential for good profits. In such Systems waste water that is loaded with metabolic by-products is recycled through biologican- and physical purification units, and re-used. Through improvements to these techniques we are able to offer very efficient and cost effective systems for both fresh- and seawater. Risk-minimization, process-control and fish health have all been considered in our designs, which are typically constructed in compact, modular units. Depending on the systems size and customer specifications our systems will be supplied with modern monitoring-, regulatory- and security units, and working accessories. Because of our extensive work and many years experience in fish farming we know how important it is to have secure, stable, safe and effective units and equipment. This knowledge is apparent in our systems, machines, instruments and accessories. Beside the development and construction of new devices and units, our systems have been tested for several years before they are approved. We offer a complete program for aquaculture from the supply of single components like: incubation-

The agri-food chain consumes about one third of the world’s energy production with about 12% of it for crop production and nearly 80% for processing, distribution, retail, preparation and cooking. The agri-food chain also accounts for 80-90% of total global freshwater use where 70% alone is for irrigation. Additionally, on a global scale, freshwater production consumes nearly 15% of the entire energy production. It can therefore be argued that making agriculture and the agri-food supply chain independent from fossil fuel use has a huge potential to contribute to global food security and climate protection not only for the next decades but also for the coming century. Provision of secure, accessible and environmentally sustainable supplies of water, energy and food must thus be a priority. One of the major objectives of the world’s scientists, farmers, decisions makers and industrialists is to overcome the present dependence on fossil fuels in the agro-food sector. This dependency increases the volatility of food prices and affects economic access to sustenance. This book provides a critical review of recent developments in solar, wind and geothermal energy applications in agriculture and the agro-food sector such as processing, distribution, retail, preparation and cooking.

In aquaculture, as in most manufacturing processes, the operating cost is greatly dependent upon the cost of energy. The objectives were to: (a) analyze the power requirements for a lobster aquaculture plant, and (b) to evaluate the use of solar energy as a cost reduction measure in plant operation. A flat plate collector system capable of supplying heat alone was compared with a total energy system in which both electrical power and heat were supplied. The flat plate collector was not cost effective because when heat was needed in December, the least amount of heat was available from solar radiation. Therefore, the collector area and cost were prohibitive. However, the total energy system was cost effective when the capital investment was amortized over ten or more years. The optimum solar power plant was designed to provide 100% of the average yearly power demands, or 60% of the December power requirement. This plant would consist of 60,000 square feet of mirror surface (3.5 acres of land for 40% packing density) which would concentrate 1500 to 2000 suns on a receiver mounted on an 85 foot tower. In the tower would be the three storage stoves which would contain the heat required to operate a 343 KWe Brayton gas turbine engine and alternator for 27 hours. Equipment to generate 3 million kw-hr annually will cost an estimated $1.3 million.
