The use of the ethanol pathway in goldfish Carassius auratus (L.) following anoxia

Goldfish (Carassius auratus) were subjected, for a period of 6 weeks, to 2h progressive hypoxia followed by 6h anoxia in closed respirometers at 15 degree C. The concentrations of glucose, lactate and ethanol were determined in whole goldfish following exposure to both hypoxia and anoxia. Lactate accumulation (mmol/kg/h) was 0.35 during the 1st week but declined to 0.14 in the 6th week of exposure to anoxia. In contrast, ethanol excreted to the surrounding water, increased from 65% to 92% of the total production in the lst and 6th week, respectively. The switch from lactate accumulation to ethanol pathway utilization, with the resultant metabolic depression and anoxia resistance is discussed

Pathway to poverty alleviation at the fishing communities of Lake Chad basin

Poverty has been variously measured in terms of income, consumption, and access to social and physical infrastructures. It is a multi-component phenomenon that cannot be measured by one single variable. This indicates that poverty alleviation or eradication requires a holistic approach. Because the existing strategies at ensuring poverty alleviation have not made impact at the Lake Chad Basin. Therefore, this study identifies the strategies that are adaptable to the area. Data were obtained on Literacy, income, quality housing, mobility, and access to infrastructure, cultural and socio-economic. The paper develops a pragmatic strategy through which the fishing communities can experience true empowerment and improved standard of living

Impact pathway analysis for research planning: the case of aquatic resources research in the WorldFish Center

In line with its mandate of poverty reduction and sustainable development, the WorldFish Center is orienting its research towards high impact scientific activity. Identifying such activities is the task of prospective impact assessment, in turn based on impact pathway analysis. The paper describes a framework for analyzing benefits from aquatic resources research, the relevant research categories, pathways to impact by category, and indicators along each pathway that can be estimated in order to quantify probable research impact.
