  • De l´origine des espèces et des premiers inventaires naturalistes aux pratiques de pêche traditionnelles et actuelles, en passant par la systématique et l´écologie des principales familles, ce livre dresse un panorama complet et richement illustré des poissons d´eau douce africains. Les représentations symboliques et artistiques ancestrales, ainsi que de nombreux témoignages actuels, invitent le lecteur à découvrir comment la pêche et les poissons continuent d´imprégner profondément les sociétés africaines. La domestication des espèces, à travers la pisciculture et l´aquariophilie, est également abordée. Ce livre n´a pas le format classique des ouvrages scientifiques. En effet, les auteurs ont fait le choix de diversifier les sources d´information et de privilégier l´iconographie, afin de rendre la lecture plus attrayante pour un lecteur non spécialiste. Ainsi, la parole est donnée à des chercheurs de différentes disciplines et à des pêcheurs, qui témoignent de leurs connaissances théoriques et empiriques des poissons et de la pêche.

  • The equilibrium of inland hydrosystems is presently a cause for concern, with species extinction rates there estimated to be 5 times higher than for terrestrial fauna in the 21st century. Urgent measures must be taken to conserve these ecosystems particularly with regard to fishes, which represent an especially rich and diverse evolutionary heritage. Fishes were long unaffected by human activity on the African continent, but anthropogenic pressure has increased in recent decades. Good management of African continental waters is thus of paramount importance in terms of heritage and economics, as fishes are a vital natural resource for the people in sub-Saharan Africa. In view of biodiversity conservation, African fishes are investigated here as a biological model owing to their enormous ecological and genetic diversity. It is essential to know the ecology and structure of various communities, and to understand the impact of human activity. This book discusses the diversity of environments, the origin and evolution of species, survival and adaptive strategies, the structure of fish communities, and the impact of human activity. It also devotes a section to fisheries and fish culture. This ambitious project summarizes the current state of knowledge on African fishes and their populations, highlighting the mechanisms regulating their equilibrium and the causes contributing to their erosion. It is a reference not just for readers involved in African aquatic environments, but for anyone interested in biodiversity conservation in general.
