| dc.description.abstract | Ornamental fish culture is fast emerging as a major branch of aquaculture globally. Aquarium keeping is the second largest hobby in the world next to photography. The ornamental fish and aquatic plant industry is gaining importance due to its tremendous economic opportunities and prospects. The world ornamental fish trade is to the tune of US$6 billion and they are easily susceptible to bacterial diseases. So to deal with such problems diseased gold fish Crassius auratus auratus were collected from the local market on the basis of their physical appearance and its movement in aquarium. Diseased tissue was taken, homogenised and bacteria were isolated on nutrient agar by spread plate method. Bacterial isolates were selected on the basis of colony morphology. In total two bacterial isolates were selected and purified by streaking on nutrient agar plate. Gram staining of bacterial isolates was performed. For identification of isolates, genomic DNA was extracted using CTAB method. After sequencing it was clear that two bacteria were Aeromonas hydrophila and Pseudomonas fluorescence out of which Aeromonas. hydrophila is more pathogenic, after incubating bacteria in the gold fish. When four different herbs and three different species of earthworm extract were used against bacteria isolated from gold fish. Out of four herbal extract Amla and out of three Earthworms species Eisenia fetida extract has maximum zone of inhibition against bacteria and there is significant increase in Hb, RBC, PCV, TLC, Length and Weight of gold fish after 90 days of incubation@ 2%/kg feed. These parameters were more for Amla extract as compared to Eisenia fetida extract. Both the extract also help in improving fish health after infestation with A. hydrophila which is clear from the histological slides of liver and intestine. | en_US |
