The prime response from the fishes was random running and hitting its head and body against the medium in which it is transported. Secondly it was found excreting a lot of ammonia waste which will degrade the water quality and there by lead to poor survival chances. Anesthetized transportation thus forms a boon in aquaculture. The fish meant for transportation is anesthetized hence it will not run and also will not eliminate wastes. A solution of 1 ml of 2- Phenoxy ethanol in 5 l of water was prepared and used for the transportation trials which were conducted in heavy duty poly bags. The average weight of brood fish was 200 g. Five numbers of brood fishes were accommodated in a bag for the transportation for 2 hours. Water quality parameters like temperature, pH, dissolved oxygen, ammonia and alkalinity were assessed following standard methods using water quantity analyzing probe (Eutech, S-660). The studies were carried out repeatedly four times during transportation so as to confirm results. The results have shown that as time proceeds the water quality of control changed drastically whereas the experiment retained the change in water quality towards a standard range throughout the transportation trial. As the fishes are anesthetized the biological activities will slow down which result in lesser consumption of oxygen, low excretory waste and so on. So anesthetizing H.kurali with 2- phenoxy ethanol is advisable.","PeriodicalId":14487,"journal":{"name":"IRA-International Journal of Applied Sciences","volume":"42 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90949021","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}

For this purpose, Cyclic Voltammetry was employed, where the redox mechanisms could be compared for reduction processes of p-nitrophenol by analysis of the voltammetric responses. Voltammetric curves of p-nitrophenol in aqueous-methanol medium on different pH using B.R. buffer for various concentrations (0.05mM, 0.1 mM, 0.15mM, 0.2mM) and scan rates at GC and Pt electrode was obtained. The very complicated reduction of p-nitrophenol revealed three reduction peaks out of which two peaks are irreversible and one peak is reversible.

A number of 374 flies sample were collected by the trapping method in the period October 2014 to October 2015 and were sorted out using certain morphological features that include; size, head, thorax, wings, legs, antennae and abdomen. The observed features of 47 randomly selected samples were recorded and were used to create an identification key that can be used for future characterization and identification of any member of the Tabanidae family. More tabanids flies were collected during the wet (52.29%) than the dry season (47.71%). A number of 5 species of Tabanidae namely; Tabanus autumnalis (Szilady 1914); Tabanus leleani (Austen 1920); Atylotus pulchellus (Loew 1858); Hybomitra mendica (Villeneuve 1912) and Philoliche sp. were reported for the first time in the state of Gedaref. The method described here has advantages over the other methods of identification; that it is simple, costless, and requires no skillful person to perform. The collection procedure is very crucial, for the specimen must be of high-quality. This key will facilitate the recognition of the vector species and its possible role in the transmission of the parasitic and/or viral animals’ diseases in the area.","PeriodicalId":14487,"journal":{"name":"IRA-International Journal of Applied Sciences","volume":"472 1","pages":"41-54"},"PeriodicalIF":0.0,"publicationDate":"2017-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89542290","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}

In developing countries, about 60% of cellulose fibers originate from nonwood raw materials such as bagasse (sugar cane fibers), cereal straw, bamboo, reeds, esparto grass, jute, flax, and sisal. Large amount of toxic effluent is released during process of paper production. Pulp and paper mill spent wash (raw effluent) is highly acidic in nature with high BOD, COD, TDS, TSS, phenol, sulphate, nitrogen, phosphorus, potassium and metals viz. Mn Zn Cu Ni Fe and Na . Effluent was treated with chemicals FeCl3 and KMnO4. pH was found to increase from 7.8 to 8.4 on increasing concentration (1 gl-1 to 5 gl-1) of KMnO4. Similarly colour, COD and BOD were decreasing with increasing concentration of KMnO4. Maximum colour, COD and BOD reduction were recorded 21.25%, 93.79% and 81.48% respectively at 5g l-1 concentration of KMnO4. Decrease in pH was recorded from 3.3 to 2.0 on increasing concentration (1 gl-1 to 5 gl-1) of FeCl3 (Ferric chloride). Decrease in colour, COD and BOD were also observed with increasing concentration of FeCl3.
