    Effect of Eichhornia crassipes in diet to enhance the growth performance of Cyprinus carpio (Linnaeus 1758)
    (CCS HAU, Hisar, 2022-08) Ruksar; Gajender Singh
    This research aimed to study the effect of Eichhornia crassipes leaves powder on the growth performance of Cyprinus carpio. In this investigation, common carp fingerlings were divided into four different groups fed on diets containing different concentrations of water hyacinth used as experimental feed incorporated with the commercial diet including T1 (commercial diet + 5% water hyacinth), T2 (commercial diet + 10% water hyacinth), T3 (commercial diet + 15% water hyacinth) and Control (only commercial diet) for 90 days. The physico-chemical parameters of water in all the treatments remained within the optimum range recommended for C. carpio fingerlings. The maximum 96.67% survivability was observed in T2 but significantly (P≤0.05) not differed among the group. The maximum weight gain (61.64 g) and length gain (17.09 cm) were observed in T2. The growth parameters viz. SGR, ADG and percentage increment in weight and length significantly (P≤0.05) improved in T2 followed by T1, T3 and control group, respectively. Feed conversion ratio (FCR) was also better for T2. Maximum crude protein (38.47%) was also recorded in T2 during biochemical estimation of experimental feed followed by T1, T3 and control group. So that, in carcass composition maximum crude protein was also observed in T2 (52.80%) followed by T1, T3 and control group. The overall, results indicated that E. crassipes leaves powder up to 10% enhanced the growth parameters of C. carpio.

    Study of avian faunal diversity in and around district Fatehabad (Haryana)
    (CCSHAU Hisar, 2022-07) Jangra, Lakshay; Ravikant
    The present investigation deals with the study of avian faunal diversity in the selected study areas of District Fatehabad, Haryana. The damage caused by the birds in major cultivated Kharif crops in the study area, Pearl Millet and Sorghum, were also studied. Periodic weekly visits were conducted in the morning and later in the evening hours in the selected study areas of Fatehabad: Badopal village, Dhangar village, Chilli Lake, Bhodia village pond and their nearby regions. Various methods were used to study birds' diversity, such as the Line Transect and Point Count methods. Ninety-one bird species were found during the study period belonging to 18 orders and 41 families. The family Muscicapidae was dominant, containing eight bird species, followed by Anatidae, containing seven bird species and the family Columbidae containing five bird species. Family Motacillidae also included five bird species. Family Accipitiridae contained four bird species. The rest of the families had a low amount of species diversity. It was found that 36 species had IUCN status of Least Concern (Stable), and 21 were Least Concern (increasing). Also, 21 species had a status of Least Concern (Decreasing), 11 had Least Concern (Unknown), and two species were found to be Near Threatened (Decreasing). Damage caused by birds in major Kharif crops in the study area, Pearl Millet and Sorghum, was studied. These crops are sown in July and harvested in November. Damage was seen at the various stages of crops: sowing stage, seedling stage, milk stage and ripened stage. 9 bird species were found to damage the crops. Both crop fields were present close to each other, so the birds were damaging both crops at various stages at different levels. Severe bird pests were Jungle Babbler, Rose-ringed Parakeet, Red-vented Bulbul and Baya Weaver, as they were present in the field in a large population at a time (more than 15). A survey was conducted in the study area regarding damage caused by birds in these crops, and it was found that birds were most active in the morning and evening. Most farmers were annoyed by the birds and required reliable bird-resistant solutions.
