Cage fish farming in the Volta lake and the lower Volta Practices and potential impacts on water quality
Concerns have been raised about the proliferation of cage fish farming in the Volta lake and the potential water quality impacts. The study was undertaken to determine current cage fish farming practices on the lake, and to assess their impacts on water quality of the lake. -
A comparative study of the pollution status of Sakumo II and Muni Lagoons in Ghana
The pollution status of Sakumo II and Muni Lagoons and Mamahuma and Gbagbla Ankonu feeder streams, which feed Sakumo II along the coast of Ghana, were assessed and compared. As expected of saline waters, pH values of both lagoons fell within a slightly neutral to saline range whilst, the feeder streams were moderately saline. Conductivity distribution also showed saline (.5.0mScm21) characteristics of the lagoons, while, the feeder streams are brackish (1.5–5.0mScm21) -
The effect of physico-chemical parameters on speciation of trace metals insediments from inland and coastal waters of Ghana
The speciation of cadmium, lead, copper, zinc, manganese and iron into exchangeable, carbonate, reducible and organic bound fractions was studied in sediments from coastal and freshwater environments in Ghana. This was relevant as the species in which metals are stored within specific sediment components is important in determining their impact on the environment -
Effects of Fish Cage Culture on Water and Sediment Quality in the Gorge Area of Lake Volta in Ghana A Case Study of Lee Fish Cage Farm
The study determined the impacts of fish cage farming on the gorge area of Lake Volta. Water and sediment samples were collected from six sites in the Lee Cage Farm; four from sections with cages and two from about 1300 m upstream of the farm which served as the control. -

Effects of Sodium Metabisulphite and Blanching Pretreatments on the Quality Characteristics of Yam Bean (Pachyrhizus erosus) Flour
: ABSTRACT Aims: To determine the effects of sodium metabisulphite and blanching pretreatments on the quality characteristics of yam bean (Pachyrhizus erosus) flour. Study Design: Evaluation of the effects of peeling, blanching and sodium metabisulphite pretreatments on the ease of drying, particle size distribution, colour and pH of yam bean flour using a 2 x 3 factorial design. Place and Duration of Study: Yam bean roots were obtained from the CSIR-Crops Research Institute, Kumasi, Ghana. All reagents used were obtained from accredited suppliers in Accra, Original Research Article Buckman et al.; BJAST, 6(2): 138-144, 2015; Article no.BJAST.2015.074 139 Ghana. Actual experimental studies were conducted at the laboratories of the CSIR-Food Research Institute, Accra, Ghana, between August 2012 and November 2013. -

Incidence of sweet potato viruses in the coastal savannah agro-ecological zone of Ghana
An experiment was conducted under field conditions to assess the incidence of viral diseases in 20 accessions of sweet potato [Ipomoea batatas (L.) Lam.]. Using symptomatology, biological indexing, nitrocellulose membrane ELISA (NCM-ELISA) and PCR, the accessions were assessed for disease incidence and symptom severity. Symptom expression varied among the accessions with severity index ranging from 2.24 in UK/BNARI at eight weeks after planting (wap) to 3.63 in US029 at 12 wap. Mean disease incidence varied significantly among the accessions, ranging from 43.2% to 96.3%.
