    Effect of vermicompost as pond fertilizer on growth performance of common carp (Cyprinus carpio linn.)
    (CCSHAU, 2010) Bansal, Nitish; Gupta, R. K.
    In the present investigations, the experiment was carried out in .0033 ha.sized ponds at the fish hatchary farm of CCSHAU, Hisar for 150 days to study the effect of vermicompost as pond fertilizer on growth performance of common carp. The different organic fertilizers viz. Vermicompost @10000kg/ha/yr, vermicompost @ 5000kg/ha/yr and cowdung @10000kg/ha/yr were used to monitored their effect on water quality parameters and fish growth. One forth dose of fertilizers were applied 15 days prior to fish stocking and remaining doses given at fortnightly interval. The fry/fingerlings were stocked @ 10000/ha/yr and fed upon supplemented feed given at 5% of their body weight. The water parameters like DO, pH, K, P and NH4-N was found in optimum range in all treated ponds and observed maximum value under the vermicompost @ 10000kg/ha/yr. The range of pH(7.90 +0.016 – 8.19+0.007 mg/l), Dissolved oxygen (7.136+0.012 – 7.22+0.01mg/l), Potassium (18.392+0.027 – 22.688+0.014mg/l), Phosphorous (0.137+0.001 - 0.166+0.001mg/l) and NH4-N (0.107+0.0 - 0.127+0.001mg/l) increased significantly(P<0.05) in the ponds received vermicompost @ 10000kg/ha/yr. As vermicompost easily and large amount of nutrients( N,P,K) release in water due to which plankton production also found to be highest in ponds treated with vermicompost @ 10000kg/ha/yr. Growth of fishes also observed maximum where the plankton population was maximum. So, it is concluded that vermicompost @ 10000kg/ha/yr shows maximum growth of fishes followed by vermicompost @5000kg/ha/yr and cowdung @10000kg/ha/yr. There is three times more growth of fishes occurred in vermicompost @ 10000kg/ha/yr as compare to control where no fertilizers were used. All the observed data statistically analysed by using completely randomized design (CRD) at 5% level of significance.

    Impact of vermicompost as pond fertilizer on the growth performance of Indian major carps
    (CCSHAU, 2011) Kaur, Jyotsaroop; Gupta, R.K.
    In the present investigations, the experiment was carried out in .0033 ha. sized ponds at the fish hatchary farm of CCSHAU, Hisar for 150 days to study the impact of vermicompost as pond fertilizer on the growth performance of Indian major carps. The different organic fertilizers viz. Vermicompost @ 15000kg/ha/yr, Vermicompost @ 10000kg/ha/yr, vermicompost @ 5000kg/ha/yr and cowdung @ 10000kg/ha/yr were used to monitored their effect on water quality parameters and growth of fishes. One forth dose of fertilizers were applied 15 days prior to fish stocking and remaining doses given at fortnightly interval. The fry/fingerlings were stocked @ 10000/ha/yr and fed upon supplemented feed given at 2% of their body weight. The water parameters like DO, pH, alkalinity, hardness, free CO2 and planktons were found in optimum range in all treated ponds. The maximum value of Dissolved oxygen (7.314 ± 0.060 to 7.573 ± 0.047mg/l), Phytoplanktons (536.000 ± 5.099 to 5210.00 ± 4.45 no/l) and Zooplanktons (186.000 ± 2.449 to 1782.00 ± 5.83 no/l) was observed under the vermicompost @ 10000kg/ha/yr. While that of pH (7.258 ± 0.54 to 8.251± 0.041mg/l), Alkalinity (199.320 ± 0.524 to 326 ± 0.743mg/l), Hardness (198.600 ± 0.872 to 252.640 ± 0.172 mg/l) and Free CO2 (0.812 ± 0.006 to 4.720 ± 0.037mg/l) were maximum in vermicompost @15000kg/ha/yr. The range of water parameters increased significantly (P<0.05) in the ponds. All the three species gained maximum growth in vermicompost 10,000 kg/ha/yr, followed by vermicompost @ 15000kg/ha/yr, vermicompost @ 5000 kg/ha/yr and cow dung @ 10000 kg/ha/yr. . Among the 3 species Catla catla showed maximum growth followed by Cirrhinus mrigala and Labeo rohita.There was two times more growth of Indian major carps as compared to control in pond treated with vermicompost @10000kg/ha/yr. All the observed data was statistically analysed by using completely randomized design (CRD) at 5% level of significance.

    Effect of herbal additives on the growth, survival and disease resistance in black molly, poecilia sphenops (Val.)
    (CCSHAU, 2012) Anita kumari; Gupta, R.K.
    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.

    Effect of herbal additives on the growth, survival and disease resistance in swordtail, xiphophorus helleri (Haeckel)
    (CCSHAU, 2012) Kalyankar, Amol D.; Gupta, R.K.
    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.
