Inland Fishes and Fisheries of NAMIBIA
The authors of INLAND FISHES AND FISHERIES OF NAMIBIA are scientists with many years of experience in their fields of work and research. Some were my students when I was a Lecturer of Zoology at Stellenbosch University many years ago. Some were members of my staff here in Namibia while I was Director of Fisheries and later Executive Director (Permanent Secretary) of the MFMR. There are no other scientists cum authors better equipped for the task of offering a high quality overview covering the freshwater fishes of Namibia and related issues linked to this subject. This book is a groundbreaking, first of its kind for Namibia, a scientifically orientated record of the topic of freshwater fish in our country. However, at the same time, it has been written in such a way that it also offers a leisurely journey for the layman wishing to increase general knowledge about Namibia's freshwater fishes.

The Springs of Florida
A rare collection of photographs that are the heart of The Springs of Florida was obtained over a period of many years. They are the result of hundreds of hours underwater, during both day and night, and in all seasons of the year. The many realms of fresh water that most often surround us are dark rivers, clouded ponds and the opaque depths of inland lakes. We cannot see into them or fathom the incessant activities of life that occurs throughout their depths. The many springs that jewel the landscape of Florida are ornate exceptions to an environment often veiled in obscurity. They are translucent openings to a dominion very rare: a crystalline and vibrant world of flowing fresh water that ...

Power Plants
Power Plants: Effects on Fish and Shellfish Behavior reviews the effects of power plant construction, operation, and maintenance on the behavior of fish and important shellfish populations such as blue crabs, crayfish, lobsters, penaeid shrimp, and bivalve molluscs. The emphasis is on the link between power plant design and fish aggregation phenomena. The effects of biocides and temperature on fish behavior are also examined. This book is comprised of 13 chapters and begins with a discussion on the economic relevance of power plants and their environmental impact on fish and shellfish populations. The potential of power generating facilities to act as a physical stimulus for fish aggregation...
