Specific physicochemical parameters influence on the plankton structure in agbarho-ogbe-ijoh stretch of Warri River, Nigeria

The continuous discharge of effluents into Warri River, impacts on its water quality parameters as well as plankton species which requires commensurate surveillance. This study focuses on its physicochemical characteristics and their influence on plankton composition and abundance. The surface water samples and plankton collected monthly from June to November 2014 were analyzed using standard […]

Inventory of ichthyological population and on some physicochemical parameters characteristics of a drinking water supply dam: the Ehuikro lake (Bongouanou, Côte d’Ivoire)

A study of the qualitative and quantitative inventory of the ichthyological population as well as on some physicochemical parameters were carried out in the Ehuikro lake in Bongouanou (Côte d’Ivoire), from July 2017 to June 2018. Monthly experimental fisheries with monofilament nets help register 462 individuals classified into 12 species, including Oreochromis niloticus and Heterotis […]

Evaluation of the physicochemical properties of four wild leafy vegetables from the Agboville region (Southern Côte d’Ivoire)

Wild leafy vegetables are an integral part of eating habits in Africa and have the advantage of being cheaper and available. This study aimed to determine the physicochemical properties of some leafy vegetables. Myrianthus arboreus (Wognonibou), Sesamum radiatum (Ahirôh), Justicia galeopsis (Assiacriba) and Solanum americanum (Débé) have been considered. The parameters determined were water content, […]

Effect of some basic physicochemical parameters of water on diversity of ichthyofauna in Jinnah Barrage, Mianwali district Punjab, Pakistan

In this context, a study was conducted to evaluate how the physicochemical parameters of water affect the diversity of fish fauna in Jinnah Barrage. A sampling data were collected of six months from July to December 2017 on every weekend survey to the barrage. The standard method of AOAC [1] was used for the determination […]

Effect of filter cake and bagasse on selected physicochemical properties of calcareous sodic soils at Amibara, Ethiopia

Salinity  and  aridity  are  two  interrelated  problems  rapidly  expanding  in  Ethiopia and  formation of soil with calcareous sodic property in Amibara irrigated farms is becoming a threat to crop productivity. A field experiment was conducted at Werer Agricultural Research Center to assess ameliorative impacts of sugar industry by-products; filter cake (FC) and bagasse (Bg) on […]

Contribution to the study of the physicochemical evolution of irrigated soils. Case of the irrigated perimeter downstream of the Mellah and Seybouse River is confluence (Guelma province), North-Eastern Algeria

The enrichment of soluble salts process of an irrigated soil causes the build-up of saline soil, which can result an increase in osmotic pressure, toxicity of certain ions to vegetation (Cl–, Na++) and soil degradation. In Algeria, more than 20% of irrigated soils are impacted by salinization/sodification process. In this regard, this work is aimed […]

Quality of physicochemical properties, color and sensory evaluation with the treatment of maturity and storage in papaya (Carica papaya L.)

The physicochemical properties of papaya have changes during the maturation and storage time. Quality of papaya that includes appearance, texture, flavor, nutritional value and security is one of the factors that affect consumer tastes. The most important factor is to know the level of maturity and storage duration. Papaya is a fruit that is relatively […]

A comparative study of physicochemical and biological water quality parameters of Iligan Bay, Philippines

Changes in the physico-chemical characteristics provide significant information on status and health of aquatic ecosystem particularly marine life. This study was conducted to analyze the physico-chemical and biological water quality parameters of the selected three coastal waters of Iligan Bay, Philippines which has been a major fishing ground for its rich fishery resources. A total […]

Influence of physicochemical conditions on the production of lipase by Psychrophilic Bacteria Isolated from Batura Glacier, Hunza Valley, Pakistan

Psychrophilic lipases have great biotechnological potential and are more preferable as compared to mesophilic or thermophilic lipases, due to their high activities at lower temperatures. In the present study, four bacterial isolates (HTB1, HTB2, LTB3, and HTB6), collected from different glaciers of Pakistan, screened for their lipase producing ability. On the basis of qualitative and […]

Screening of polluted water of different habitat for some physicochemical parameters and algal flora in summer season of District Charsadda, KP, Pakistan

The purpose of the study was to assess the algal flora and water quality of summer season of district Charsadda. There are three tehsil in district charsadda; Tehsil Charsadda, Tangi and Shabqadar were studied. From three sampling sites Water samples were collected in summer season for three months (June – August 2015). For identification of […]
