Marine cyanobacterium Synechocystis salina was tested as a supplementary feed for the shrimp Penaeus monodon. The feed increased average length of the shrimp significantly (p<0.05) by 16.95%. The feed decreased significantly the consumption (37.14%), fecal output (19.64%), assimilation (44.04%), metabolism (73.78%) and assimilation efficiency (10.68 %) in the shrimp. However, the feed increased the gross conversion efficiency (45.75%) and net conversion efficiency (63.19%) in the shrimp, whereas the feed decreased the conversion efficiency (30%) and food conversion ratio (42.81%) in the shrimp. The feed significantly increased levels of carbohydrate (30.6%) and lipid (12.5%) in the shrimp. The results suggested that Synechocystis salina was a suitable supplementary feed to the shrimp Penaeus monodon, based on higher gross conversion efficiency and biochemical constituents and lower food conversion ratio.
