Book Description
An understanding of the ecology of a fish pond is essential for the achievement of steady and high fish production in ponds. For the ecologist, the fish pond is a small laboratory: easy to investigate and responding rapidly to manipulation. For the aquaculturist, the ecology shows the ways and means of interventions ensuring an increase of production. The book deals with the different aspects of natural production within a pond, referring it to African conditions: considering first the role of soil as source and sink of nutrients for the water, then nutrient cycling within water and the fate of fertilizers added to ponds, and finally the contribution of natural productivity to fish production. The important sum of information brought together in this volume is valuable for both aquaculturist and ecologist, who lack a handbook on the ecology of a fish pond. It will capture the interest of African aquaculturists and stimulate aquaculture research on natural production.

Book Description
The modern British Commonwealth, linking fifty countries around the world in voluntary association, cooperation, and consultation, is a unique body in world history. The area of its member countries covers a third of the globe and collectively their peoples represent a quarter of the world's total population. Though essentially different from the British Empire from which it originated, the Commonwealth shares many common historical ties with Britain. Patricia M. Larby and Harry Hannam have assembled an unrivaled body of literature to illustrate the growth of the Empire into the Commonwealth. This extensive bibliography identifies, lists, and annotates the most important publications on the development and growth of the Commonwealth; its present status and functions; and its role in education, literature, sport, and the arts and sciences. It includes its historical origins: its cooperation in economics, politics, and international issues such as the environment; and its many spheres of professional activity including medicine, law, and architecture. Strong emphasis is placed on the role of the English language in the Commonwealth and as a medium for creative literature in many disparate cultures worldwide. The Commonwealth appears at a time when this unique organization is on the threshold of a new era in its history. The proposals emerging from the 1991 Commonwealth Heads of Government meeting include statements on democracy and human rights; environmental affairs; and global concerns such as international crime, drug abuse, and AIDS. No previous comprehensive bibliography of the Commonwealth exists, and this volume fills a long-standing gap in the bibliographical coverage. It will be an essential reference source for libraries and scholars involved in Commonwealth studies and will be of particular interest to historians, political scientists, economists, and educators.

Book Description
The cichlid fishes are an important group, being widely used in scientific research and as popular fish with aquarists. This group contains mainly small species which adjust quickly to captivity, exhibiting a readiness to breed and long periods of parental care for the young. This books comprehensive volume describes the current knowledge on the behaviour and ecology of the cichlid fishes.
