This paper considers the standard ecotoxicity tests done so far for assessing the hazards of engineered nanoparticles and potential negative effects that engineered nanoparticles may have on environment. Research and development in nanotechnologies increase strongly and attract substantial funding, but environmental consequences of resulting materials and applications are poorly known. We prepared nanoparticles by continuous sonication and by ultra filtration. Artemia salina was differentiated to five life stages based on certain easily distinguished features and were exposed to different concentrations of Titanium Dioxide and Fullerene using 48 hours acute toxicity testing. Images of the particle solutions were recorded using TEM and the median lethal concentration was determined in each life stage. Exposure to sonicated nanoparticles shows varied mortalities in different stages of Artemia salina where as filtered solutions showed increasing mortality with increase in concentration. We conclude that uncontrolled and unobserved release of these nanoparticles either as byproducts or medical wastes, could have a large negative consequence on the aquatic and terrestrial organisms, particularly on the humans.

Aquaculture is now viewed as a strong option to increase fish production as it plays a vital role in providing food security in India. Aquaculture informatics can be described as the scientific application of Information technology in biological concepts that enhance the productivity and economic viability of aquaculture sectors. Though there are lot of developments in various aquaculture sectors around the world, Aquaculture in India is still in infancy to use the information from different parts of the country. Advances in electronic communication, combined with specific cooperative efforts, should be used to increase the information exchange in the region. It is nation's part to educate the fish farmers through community based organization and to provide an information system, in low cost, to fulfill their requirements. In order to develop a single hub for the integrated activity, some community based organizations are formed like fish farmers association, self help group or aqua club. This paper is on the integration of aquaculture information based tools under one hub to design to work through a community based system.
