Keeping these vital features of poultry management in mind, the present study assessed the productivity, disease incidence and profitability analysis of a government, 10 private and 10 backyard smallholders’ poultry farms for rearing and marketing three available chicken breeds viz., indigenous (Deshi), Fayoumi (an exotic) and Sonali (a crossbred) in 10 Upozillas or Police Stations of Rajshahi district viz. Baghmara, Boalia, Godagari, Mohonpur, Motihar, Paba, Puthia, Rajpara, Shahmokdum and Tanor. The investigation was conducted from January to December 2014 during which data were collected twice a month. In terms of producing live chickens for marketing, productivity of the farms varied significantly during both January-June and July-December rearing seasons (P<0.001). The private farms always outnumbered the government and backyard counterparts in producing chickens. The study identified nine parameters on disease incidences on the poultry production system from elevated (score 5) to absence of acceptable practices (score 1), which exhibited significant variation (P<0.05) except viral, fungal and bacterial diseases and the rate of disease occurrence per rearing period. The mean scores for disease incidences declined during July-December period of rearing. Results on the profitability analyses showed highly significant difference between the farms (P<0.001) where it appeared that strict bio-safety oriented management practices, coupled with the selection of fast growing and heavy laying breeds of chickens could ensure profitability of the poultry farms in the study area.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"19 1","pages":"153-163"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86041834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Isolate LPF-5 demonstrated higher lipase activity and it was identified as Aspergillus niger based on morphology of its Petri plate culture, microscopic study of its slide culture and with the help of relevant literatures. Further an effort was made to increase the production of extracellular lipase by subjecting the most potent lipolytic fungal strain A. niger LPF-5 to the strain improvement by induced mutagenesis using UV radiations and nitrous acid. Among the all tested mutagens, nitrous acid was found to be the best mutagen (incubation time of 15 minutes) for inducing the favorable mutation in fungal strain A. niger LPF-5 which enhanced the lipase activity up to 30% (105.19 ± 0.91 U mL -1 min -1 ) when compared to lipase activity (81.00 ± 0.30 U mL -1 min -1 ) of wild strain while the lipase activity of the best UV mutant (A. niger UV3), obtained after an incubation of 6 minutes was 94.30 ± 0.54 U mL -1 min -1 , which was 16.41% higher as compared to wild strain of A. niger. These results indicate that UV light and nitrous acid both were effective mutagens but nitrous acid was more potent mutagen than UV light.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"3 1","pages":"145-152"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87340483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Levels of polycyclic aromatic hydrocarbons in Tilapia zilli from Qua Iboe River estuary (QIRE) Nigeria and the carcinogenic health risk induced by its consumption were studied. Fish samples were collected from five stations and a Control during wet and dry seasons and analyzed for PAHs using gas chromatography with flame ionization detector. Carcinogenic health risk assessment using recommended models by USEPA was done. Concentrations of total PAHs ranged from 1.527E-03 to 5.986E-02 mg/kg, high molecular weight PAHs recorded a range of 1.239E-03 to 1.424E-01 mg/kg while low molecular weight PAHs ranged from 2.814E-04 to 3.166E-03 mg/kg. Concentrations of C-PAHs at the study area were higher than at the Control site. Levels of B(a)P in Tilapia zilli for both seasons were lower than the EU limit however, the potency equivalent concentrations due to exposure to C-PAHs via its at all locations in both seasons were above the screening value. Thus, consumption of Tilapia zilli from the area studied may result in carcinogenic health effect. The study also identified presence of anthropogenic inputs of PAHs and pyrogenic PAHs originated from gas flaring in the area. Regulatory legislation on environment should be instituted to forestall sub lethal effect on aquatic flora, fauna and human.

Koklass (Pucrasia macrolopha) species is facing tremendous pressures due to poaching and destruction of habitat. This species is classified as least concern species with decreasing population trend according to IUCN Red List of Threatened Species and also classified under endangered species according to Red Data Book of Zoological Survey of India. There is need to understand and manage habitats of species in order to prevent extinction of endangered species. Wildlife habitat suitability analysis using GIS have been found to be successful in many studies. In the present study, habitat suitability model for Koklass Pheasant of Churdhar Wildlife Sanctuary, HP, India was developed using geospatial technology which predicts suitable habitat zone. Different thematic maps such as land use/cover, forest type, drainage, roads and sighting locations of Koklass Pheasant are overlaid using Weighted overlay analysis model. The Habitat Suitability model shows different habitat potential zones of this Pheasant which are 5.9%, 24.9%, 45.4% and 23.7% for least, moderate, moderately high and most suitable respectively. The least and moderate suitable zones could be due to various anthropogenic activities such as deforestation, road construction activities, grazing by domestic cattles, noise pollution and encroachment of land for agricultural purpose. Habitat suitability analysis of Koklass Pheasant can be considered as the initial phase towards the conservation approach of this species.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"13 1","pages":"93-101"},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81691427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
