The fresh waters of the British Isles are diverse, ranging from torrential hill streams to powerful rivers and wide, meandering lowland channels. Canals and drainage channels, ranging in size from ditches to the large Fenland drains of eastern England also hold fish, as do reservoirs, lakes, ponds and other still water bodies. The fish themselves are correspondingly varied. This pocket-sized book provides information about the 54 native, invasive and naturalised species found in the UK today, and includes a photograph of each to allow easy identification

Livebearers focuses on four families of fish which contain many of the most attractive and popular species in the tropical fish hobby today, including guppies, mollies, swordtails, and platies. The families include Goodeidae (Mexican livebearers), Anablepidae (four-eyes and others), Poeciliidae (guppies and others); and Hemirhamphidae (halfbeaks). Author David Alderton explains that hobbyists have applied the term livebearer to these four families for convenience even though there are fourteen families in the wild that reproduce by bearing live young. The chapter "Where in the World?" focuses on the natural history of these families, their distribution, and lifestyles. Hobbyists looking to begin an aquarium of livebearers or to expand their existing communities will find useful information in the chapter called "The Different Groups," in which Alderton discusses age considerations, health matters, and sex. The chapter also describes the four families and the most common genus/species of each. Included are sixteen representatives of the Family Goodeidae (e.g., Allodontichth, Characodon, and Skiffia), three genus of the Family Anablepidae (Anableps, Jenynsia, and Oxyzgonectes), twenty-six representatives of the Family Poeciliidae (e.g., Belonesox, Fiexipenis, and Limia); and three genus of the Family Hemirhamphidae (Dermogenys, Hemirhamphodon, and Namorhamphus).This colorful, user-friendly guide offers basic information on the anatomical characteristics, housing options, required aquarium equipment for livebearers as well as their feeding habits and food requirements (greenstuff, carotene-rich foods, live foods, meat, etc.). The breeding habits of livebearers have ensured their popularity with hobbyists, and the chapter on reproduction describes the various breeding habits of livebearers and outlines successful breeding strategies for interested hobbyists. In the chapter on health care, the author offers solid advice about caring for livebearers to maximize their lifespan in captivity, which is typically only a few years. He also gives information on signs of illness and some basic diseases that can be treated by the fish keeper.The final chapter offers photographs and distribution maps for sixteen popular livebearers of all four families, including information on size, physical description, natural habitat and behavior, and required aquarium conditions. The authors livebearer hit parade includes the butterfly goodeid, rainbow goodeid, black-finned goodea, four-eyed fish, guppy (millions fish), black molly, sailfin molly, swordtail, platy (moonfish), mosquito fish (dwarf and large), humpbacked (black-barred) limia, black-bellied limia, pike livebearer (piketop minnow), knife (Alfaros) livebearer, and wrestling halfbeak. Resources, glossary, and index included.

Y de tres momentos de la ciencia y del territorio hoy conocido como Colombia.¿Como llegaron los bagres hasta las cumbres de la gran cordillera suramericana?Este enigma ha preocupado desde finales del siglo XVIII a sucesivas generaciones de naturalistas -como Alexander von Humboldt, Carl H. Eigenmann, y el equipo de Carlos Andres Lasso- cuyas investigaciones, contra todo pronostico, permiten develar una saga que se adentra en la noche de los tiempos.La historia de estos peces es entonces geologica porque esta ligada indisolublemente a la de los continentes y a la del relieve terrestre.

This illustrated guide describes the many ways that coarse fish species depend upon the diversity of habitats in river systems and considers how this dependence changes throughout the stages of their lives - from spawning and eggs, through to the juvenile and adult stages- and with changing seasons and river conditions. This knowledge is important if we are to understand the many population bottlenecks and the variety of coarse fish species that have resulted from historic changes to our rivers. It is also important if we are to manage rivers positively to protect and improve the vitality of coarse fisheries - a process that will also benefit the wider wildlife community with which coarse fish are interdependent.
