Mass production of live food and their by-products in semi-arid areas

The semi-arid area possesses several key factors such as sun light, suitable temperature, nutrient rich soil, saline or brackish water, land availability which make it candidate for certain organisms biomass production. In this talk, production of unicellular algae, Rotifer, some crustacean, insect and fish will be discussed. The priority is given to job enhancements for local community using traditional experiences and advanced methods in closed culture systems. The advantages of using locally available species greatly help the sustainable use of resources and their conservation in the nature. In addition, due to unique adaptation of species, there is an opportunity to establish a Bio-Bank for genetic and natural resources. Apart from biomass production, the by-products of these farms are used in pharmaceutical and medicinal industries and green fuel production.As an example, some comparative added values to land use, level of biomass production and economical investments from other countries achievements are given.
