    Ornamental fishe trade earns foreign exchange besides serving as a source of employment. Diseases are a crucial factor which inhibits the expansion of aquaculture. Moreover, the bacterial infections are considered the major cause of mortality in aquaculture. Use of herb plants in aquaculture is gaining success. Recently it is considered as an alternative to antibiotics, chemicals in fish health management. The present investigation was designed for a period of six weeks to study the influence of herbal additives on the growth, diseases resistance and survival in black molly, Poecilia sphenops. From diseased fish black molly (Poecilia sphenops) six bacterial strains were isolated and identified. The herbal extract of Ocimum sanctum (Tulsi), Withania somnifera (Ashwagandha), Aloe vera (aloe) and Emblica officinalis were tested to find out there antibacterial properties against isolated bacteria under in in vitro condition. All herbal extract showed inhibitory effect against pathogenic bacteria, but Emblica officinalis extract was most effective among all herbal extract. Future studies were conducted to test the efficacy and potential of most suitable herb extract (Emblica officinalis) under in vivo conditions. Fish fed with herbal extract (Emblica officinalis) in different concentration (@1, 1.5 and 2% of feed ingredients) gave better results in terms of hematological parameters, growth and percent survival rate as compare to control group. Level of Hb, TEC, TLC and PCV was highest in fish fed with Emblica officinalis diet @ 1.5% followed by Emblica officinalis diet @ 1%, 2% of feed and then control group. Emblica officinalis extract @ 1.5% of feed yield highest mean weight (4.23g) and length (3.62cm) gain. The highest survival rate (95.8%) was also observed in Emblica officinalis fed group at 1.5 per cent concentration. Hence the alternative herbal biomedicines prove to be very effective in aqua-cultural operations.
