Management strategies for fish populations in small impoundments are reviewed with consideration given to intensification techniques applied throughout the United States and Canada. The concept of balance in fish populations is used as a basis for illustrating the importance of maintaining desirable predator/prey relationships through stocking and harvest regulation of keystone predators. Generally, harvest levels for predators are reduced when species diversity and structural complexity of the environment are increased. Intensification is also achieved by enhancing water fertility through liming and fertilization. Case studies are presented representing contrasting climatic regions of North America while demonstrating similarities in management style. Principles and practices presented in this paper should be adaptable to the management of fisheries in small water bodies over a wider geographical range than discussed.

This publication presents the proceedings of a workshop held in Ghana in 1999 at which experts from Burkina Faso, the Ivory Coast, Ghana, Mali and Zambia presented national reviews summarising developments and research in the field of irrigation and aquaculture (IIA) activities. The workshop proposed the establishment of a regional IIA network for Africa and considered its objectives, structure and initial plan of action.
This is the story of Peter, son of Paul. Like many of us, Peter is unsure of what life has in store for him. What path should he take? How should he sculpt his life? He, after all, is a young, vigorous, and (from his vantage point) reasonably intelligent young man. He is a young man who has followed the growth curve of young men everywhere--now looking to what lies over the horizon. What can he do? What does he want to do? What should he do? Peter, like most in his shoes, finds it hard to answer these questions. He is burdened with history while blessed with freedom of choice. But what should he choose? Peter's journey is an adventure that takes him to strange and, at times, dangerous places--introducing him, at times, to strange and dangerous people, while simultaneously introducing him to love. It is an exploration that takes him to the fringes and tests his soul. Peter's journey is ultimately an attempt to find answers to his questions. While it is uncertain if he finds what he is looking for, he truly finds much that he never knew existed.
Charlie Stancik was born in sage and juniper scrub on lands reclaimed from ancient waters—lands whose first outside settlers were Bohemians seeking the end of the rainbow. Charlie seeks his own Xanadu, feeling he must leave the lake bed to find the life he deserves—the life he needs. His pilgrimage takes him to the shores of Lake Michigan, evolving from homelessness to a position of some wealth and power—evolving from a lost soul to someone who has found his soulmate. This seemingly implausible trajectory had been made possible by the enigmatic Robin McCandless and his obscure and potent company, Delpro. Work with Delpro takes Charlie to the furthest corners of the globe and into the darkest shadows. Charlie becomes a key actor in a drama he scarcely understands—a drama that places him in great jeopardy. Charlie the prodigy walks a fine line with Charlie the criminal—the path ultimately guided not by the elusive Robin McCandless but by Rodney Mills, a government investigator with a long history with Delpro and its sordid acts. In the end, Charlie realizes that love in the present and freedom from the past are the riches he has sought.
