“…For increasing the fish production for better economic returns, one alternative is to fertilize the pond with cheap, easily available and suitable organic manures; vermicompost is one of these. The known usefulness of vermicompost in agriculture not withstanding (Meena, 2003;Saini et al, 2008aSaini et al, ,b, 2010, its usefulness in aquaculture as an organic manure for augmentation of fish production has not yet been extensively explored and only a few reports on this subject are available where efficacy of vermicompost with other commercial manures in enhancing the fish production has been compared (Deolalikar and Mitra, 2004;Kumar et al, 2007;Chakrabarty et al, 2009;Kaur and Ansal, 2010). Our earlier study revealed higher survival rate of Indian major carps in ponds fertilized with vermicompost over those treated with other manures (Godara et al, 2015a), without adversely affecting the water quality parameters (Godara et al, 2015b).…”

Vermicompost is one of the ready to use organic fertilizers. The efficacy of vermicompost vis-avis other organic fertilizers for fish production has not yet been extensively explored. For this purpose, an experiment was performed on three Indian major carps viz. catla (Catla catla Ham.), rohu (Labeo rohita Ham.) and mrigal (Cirrhinus mrigala Ham.). The fry/fingerlings acclimated for 10 days prior to the commencement of experiment were stocked in 5.54×6.15 m size ponds with a stocking density of 30 fish per pond in a ratio of 3:4:3, respectively. Six treatments viz. a control (T 1) without any treatment, pig manure at 4,000 kg haG 1 yearG 1 (T 2), poultry manure at 6,000 kg haG 1 yearG 1 (T 3), cow dung at 10,000 kg haG 1 yearG 1 (T 4), vermicompost at 10,000 kg haG 1 yearG 1 (T 5) and vermicompost at 15,000 kg haG 1 yearG 1 (T 6) were used and their effect on growth performance of these fishes was recorded every month for a period of one year. All the six treatments caused significant monthly increase in fish growth; the three fish species gained maximal growth (length and weight) in ponds treated with vermicompost at 10,000 kg haG 1 yearG 1

“…Many organic fertilizers are being used for pond fertilization (Dhawan and Kaur, 2002a, b;Hossain et al, 2003;Jha et al, 2004); vermicompost is the new addition to this pool which not only promotes the fast growth of fishes (Godara et al, 2015a) but also keeps the aquatic environment (hydro-biological parameters) congenial for their growth (Godara et al, 2015b). Vermicompost is a product of vermi-biotechnology that is frequently used in agro-ecosystems as organic fertilizer (Saini et al, 2008a(Saini et al, , b, 2010. The advantage of use of vermicompost as organic fertilizer is the quick availability of nutrients in 'ready-to-uptake' forms (Nath and Lannan, 1992).…”

Use of organic fertilizers has become very common in the modern piscicultural practices; vermicompost is a new addition to the list of such fertilizers. The efficacy of vermicompost was better than the other fertilizers both in keeping the hydro-biological parameters of treated waters in favourable ranges as well as in maximizing the fish growth. However, its effect on the pathogenic bacterial profile of treated waters is not known. To accomplish this objective, an experiment was performed in 5.54×6.15 m size ponds stocked with three species of Indian major carps viz. catla (Catla catla Ham.), rohu (Labeo rohita Ham.) and mrigal (Cirrhinus mrigala Ham.) at 30 fish per pond in 3:4:3 ratios, respectively. Six treatments viz. a control without any treatment (T 1), pig manure at 4,000 kg haG 1 yearG 1 (T 2), poultry manure at 6,000 kg haG 1 yearG 1 (T 3), cow dung at 10,000 kg haG 1 yearG 1 (T 4), vermicompost at 10,000 kg haG 1 yearG 1 (T 5) and vermicompost at 15,000 kg haG 1 yearG 1 (T 6) were used to monitor their effect on the pathogenic bacterial populations in the treated pond waters. One fourth doses of fertilizers were applied 15 days prior to the fish stocking and the remaining doses were given at fortnightly intervals; the supplementary feed was given at 2% of the body weight of fishes. The pure culture of bacterial isolates segregated from the pond sediments were identified by primary, secondary and tertiary tests and confirmed for their pathogenicity through in vitro and in vivo tests. Overall, seven gram negative pathogenic bacterial strains (viz. Aeromonas hydrophila, Escherichia coli, Enterobacter aerogens, Pseudomonas fluorescens, Klebsiella oxytoca, Pseudomonas aeruginosa and Shigella sp.) and three gram positive strains (viz. Micrococcus luteus, Staphylococcus aureus and Staphylococcus sp.) were isolated from the pond waters treated with different manures. The in vitro and in vivo tests confirmed the pathogenic nature of these bacteria. The abundances of the heterotrophic pathogenic bacteria were minimal in the pond waters treated with vermicompost at 10,000 kg haG 1 yearG 1 followed by those treated with vermicompost at 15,000 kg haG 1 yearG 1 ; the abundances of pathogenic bacteria were higher in waters treated with other fertilizers including under the control treatment. Under other than these two vermicompost treatments, the abundances of pathogenic bacteria were variable depending upon the bacterium-fertilizer type. On the basis of these results, vermicompost at 10,000 kg haG 1 yearG 1 seemed to be the best among the five organic fertilizer treatments in controlling the abundance of pathogenic bacteria in the treated pond waters.

-The production and characterization of cellulase from thermophilic strain Bacillus sp. C1AC5507 was studied. For enzyme production, sugarcane bagasse was used as carbon source. The produced carboxymethyl cellulase (CMCase) had a molecular weight around 55 kDa and its activity varied between 0.14 and 0.37 IU mL -1 in conditions predicted by Response Surface Methodology. The optimum temperature and pH for the CMCase production were 70 °C and 7.0, respectively. The enzyme activity was inhibited mostly by Cu +2 and activated mostly by Co +2 , Mn 2+ , Ca +2 and Fe +3 . Our findings provide a contribution to the use of natural wastes such as sugarcane bagasse as substrate for growth and production of thermophilic CMCase. Further optimization to increase the production of cellulase enables the use in industrial applications.
