“…Strangely, there has been little documentation of the effects of oil spills on rocky shores in South Africa. Day et al (1971) recorded the effects of the oil spill associated with the grounding of the Wafra near Cape Agulhas, and in 1977 oil spilled as a result of a collision between the Venpet and the Venoil was noted to have its most devastating effects in sheltered areas, such as estuaries and rocky coves (Moldan et al 1979). In 1994, the sinking of the Apollo Sea off the West Coast released about 2 500 t of heavy fuel oil that deposited on both rocky and sandy shores (Glassom et al 1997).…”

“…These changes may be natural (e.g. a river flood) or induced by some anthropogenic activity such as a pollution event (Moldan et al 1979). Although both natural and human induced mortalities have been recorded in southern African estuaries, the increasing frequency of occurrence of the latter is cause for concern.…”

The idea of writing this book arose from a discussion I had with Professor Paul Skelton in 1991 while he was busy with his volume A Complete Guide to the Freshwater Fishes of Southern Africa. Paul succeeded in persuading me that a book on the fishes of southern African estuaries was needed and that I should start 'rattling my keyboard'. Paul, thank you for starting me off on what turned out to be a seven year long project of renewed discovery and interpretation of the estuarine ichthyological data base.The contents of this book are drawn from past and present information about the fishes of southern African estuaries, some of which was published long before I embarked on a career in ichthyology. To the pioneers of estuarine and ichthyological research on the subcontinent, especially the late Professors John Day and J.L.B. Smith, I express my gratitude for lighting the path for the rest of us to follow. I would also like to thank the late Professor Waldo Meester, Head of the Zoology Department at the University of Natal during the 1970s, for sharing his views with six young honours students. In his 1972 inaugural address to the university entitled The Human Breakthrough he stated "I would like to dream of a world in which our knowledge of nature is far more complete than it is now, and in which this knowledge is used for the betterment not only of mankind but of the natural world on which we depend". It is a dream which I fully endorse and convey, in turn, to my students.The bulk of this book draws on the last two decades of research, during which time numerous people have actively and unselfishly assisted me to explore the fishes of southern African estuaries. To all these friends, colleagues and students I express my sincere appreciation and gratitude. In particular, I should like to thank the following for their support and encouragement;

“…The river mouth was closed by a manmade sand bar to prevent oil redistribution and suction pumps removed the accessible sunken oil mats [6]. Heavy fuel oil, 5000 t/ 0.94-0.97 g/cm 3 The oil quickly emulsified into large rafts that barely floated.…”

Based on past spills, the conditions under which floating oil mixes with enough sand to form sunken oil mats (SOMs) are identified. SOMs form mostly during spills of heavy crudes or heavy fuel oils, but also highly weathered and viscous crude oils. They usually form when oil and sand are both suspended in the water column by breaking waves or by the erosion of heavily oiled sand from the beach. The oil–sand mixture needs an area in the nearshore where it can accumulate into mats, such as in troughs or inside lagoons, where wave energy is reduced. SOMs can be oily (>40% oil) or sandy (<<40% oil), with oily SOMs posing risks of the oil separating from the sand and refloating. Methods are described for SOMs detection and recovery based on their location, in either the surf zone or the open-water environment seaward of the surf zone. A matrix provides guidance on methods based on effectiveness and environmental impacts for different site conditions.
