Aquaculture production globally had been increased thus raised up some related issues such as nutrition and food safety. As an attempt to overcome these issues, incorporation of herbs in feed is started. For this current study, Cosmos caudatus was used as food additive in bagrid catfish, Mystus nemurus fingerling. This herb is common and normally consumed by locals since it believed to help in improving human health. The crude of C. caudatus was incorporated in the fish diet at the level of 0, 0.5, 1.0, 1.5 and 2.0%. Six hundred fish with average of initial weight of 3.05±0.39g were distributed into 150L fiberglass tank in quadruplicate. The fish was fed twice a day until satiation level. From the data collected after 60 days of feeding, there was significant difference (P<0.05) seen for the final weight of fish among treatments. This ongoing study is considered a preliminary study and the whole results will be presented later.
