Effect of Enriched Feed by Immunostimulant on Immune Response and Growth of Humpback Grouper, Cromileptes altivelis
<p>Humpback grouper, <em>Cromileptes altivelis</em> is susceptible to low quality of environmental condition so that it is vulnerable to bacterial infection. One of the methods to solve this problem is improvement of nutrition by using immune response present in fish body. Supple...
