Evidence In Blue

Global growth in aquaculture is underway – a “blue revolution” featuring rapid increases in demand for fish and a corresponding surge in aquaculture production. This paper describes the fast-growing tilapia value chain in Ghana to demonstrate the features of a nascent blue revolution in sub-Saharan Africa (SSA) and to illustrate its potential for job creation and reducing poverty and food insecurity there. Tilapia production has been growing at 15 percent annually in SSA, but imports are also surging to satisfy the growing appetite for tilapia. This paper illustrates how aquaculture can grow sustainably in SSA within the context of growing demand and global competition. A value chain analysis is conducted using secondary data analysis, desk reviews of experiences and lessons from other countries, interviews with 95 actors in the tilapia value chain in Ghana, and detailed production and profitability data from Ghanaian tilapia farmers. A profitable farmed tilapia industry has been established in Ghana with the potential to expand supply to satisfy local demand and to export to neighboring countries. Productivity in the industry has grown mainly through reducing the mortality rates of fingerlings and improvements in the supply of locally-produced high-quality fish feed. Feed costs remain high. However, there is potential to reduce those costs by improving the productivity of crops that are used in fish feed, particularly maize and soybean. Reducing local feed costs will have positive spillover effects on both other pond-based aquaculture systems and on the livestock feed sector. Moreover, Ghana can expand it fish feed production to be an important source of feed within SSA. The industry can further increase aquaculture productivity through the adoption of faster-growing fish strains and better management practices. Ghana’s aquaculture sector could grow even faster by adopting lessons from other countries, including on infrastructure provision, fiscal incentives for the production of fish feed ingredients, and sustainable fish farming practices, particularly through paying close attention to water and feed quality and addressing food safety concerns within the sector.

John Banville’s stunning powers of mimicry are brilliantly on display in this engrossing novel, the darkly compelling confession of an improbable murderer. Freddie Montgomery is a highly cultured man, a husband and father living the life of a dissolute exile on a Mediterranean island. When a debt comes due and his wife and child are held as collateral, he returns to Ireland to secure funds. That pursuit leads to murder. And here is his attempt to present evidence, not of his innocence, but of his life, of the events that lead to the murder he committed because he could. Like a hero out of Nabokov or Camus, Montgomery is a chillingly articulate, self-aware, and amoral being, whose humanity is painfully on display.

Based on many years of columns from School Library Media Activities Monthly , authors, Daniel Callison and Leslie Preddy present key terms in a working theoretical model that may be used in developing and understanding the power of information inquiry in instruction. This book is both a revision and an update to Key Words, Concepts and Methods for Information Age Instruction (LMS Associates, 2003). New columns from School Library Media Activities Monthly are included and entirely new key words for instruction are introduced. These key terms have immediate value for staff development purposes. They are reproducible and can be used in building year-long study group programmes in schools and libraries or as weekly discussion handouts. An entirely new section on inquiry has been added. An in-depth and invaluable section of resources and web sites has been updated. In addition to the theoretical base, the authors include much practical instructional application for immediate use. The Blue Book on Information Age Inquiry, Instruction and Literacy is the new definitive work on information inquiry and information literacy instruction. The authors have thoughtfully blended theories in education and library science in a book that finally gives us a picture of the huge role of the school library media specialist as both a teacher and a librarian who needs to understand, interpret and instruct students in the skill of inquiry, the basis of all learning. -- Back cover.
