Description Ornamental fishes form an important commercial component of aquaculture providing for aesthetic
requirements and upkeep of the environment. Diseases are a crucial factor which inhibits the expansion of
aquaculture. Moreover, the bacterial infections areconsidered 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 resistanceand survival in Swordtail, Xiphophorus helleri.
From diseased fish Swordtail (Xiphophorus helleri) six bacterial strains were isolated and identified. The
herbal extract of Allium sativum (Garlic), Raulfia serpentina(sarpgandha), Zingibera rhizoma (Ginger) and Allium
cepa (Onion) 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 Allium sativum extract was
most effective among all herbal extract. Future studies were conducted to test the efficacy and potential of most
suitable herb extract (Allium sativum) under in vivoconditions. Fish fed with herbal extract (Allium sativum) in
different concentration (@1, 1.5 and 2% of feed ingredients) gave better results in terms of growth, survival and
hematological parameters, however Allium sativum extract @ 1.5% of feed was most effective among alldiets.
Hence the alternative herbal biomedicines prove to be very effective in aqua-cultural operations.
