Abstract

,4 technology ,[or the production oJ the green alga, Scenedesmus acutus, and blue green alga, Spirulina platensis, in clean water has been det;eloped at out" Institute to suit Indian conditions. Experience gained on algal production technology in India indicates the seopejor applying this at the rural lereljbr use in the production ql animalJeed. Spirulina is the most promising alga in t'iew o fits amenabili O' to low lerel technology. Nutrient input to the euhures is one oj the expensive steps. It i~s shown that agricultural and domestic' wastes can be eJ]~cticely reeycled Jor algal biomass production by replacing, at least partly, the nutrient inputs. Urine and honemeal reduce the inputs oJnitrate, calcium and phosphate salts into the cuhure medium. Sheep's blood has a growth promoting eJJect on algal cultures and a good potentialJor application. Carbon dioxide enriched air ~'aerobic biogas'~produced by composting cow dung, can be used as a carbon sourcejor algal cuhication. Seceral experiments carried out in India indicate the possibility q[deceloping an integrated algal production system in rural areas by means oj which wastes can be eJ]ectit:ely recycled. The use q/algae in poultry and fish jeeds is a distinct possibility jor the future.
