Abstract: 2% of Anabaena powder was added into the feeds for chickens, all female carp, Macrobrachium nipponense (De Haan) and Penaeus in present studies.In the experiment with chicken, there were no change significantly in the body weight, but the butchery rate, half-net chamber rate and net chamber rate increased at different degree, and the quality, color and luster were improved.Quantitative analyses of heavy metal showed that the content of copper, iron, magnesium, cadmium and aluminum in all the chicken fed by algae were lower than those of the controls, but zinc content increased.The Anabaena powder had apparently positive effect on the growth of All-female carp, Macrobrachium nipponense and Penaeus.The survival rate of fingerling increased while the feed coefficient decreased.Anabaena feeding could accelerate the growth of both Macrobrachium nipponense and Penaeus japonicus, so that productions increased.After 45 days of feeding, the Penaeus japonicus increased 14.49% in body length and 10.4% in body weight.These results .suggested that it is feasible for Anabaena to be used as the feed of poultry and aquicultured animals.
