It is perhaps because fishes live in a buoyant medium, whether it be fresh or sea water, that they show a diversity in body shapes that is unparalleled by other vertebrates.
Fish constitute an important natural renewable resource and any reduction in their ability to propagate as a result of human interference may have significant socioeconomic consequences.
Anguillid eels have fascinated biologists for centuries due to their spectacular long-distance migrations between freshwater habitats and their spawning areas far out in the ocean.
This book covers the biology, ecology, genetics and aquaculture of the Asian Seabass or barramundi (Lates calcarifer), a commercially and recreationally valuable species.
Beach-spawning fishes from exotic locations on most continents of the world provide spectacular examples of extreme adaptations during the most vulnerable life cycle stages.
The present work evaluates the toxic effects of some environmental stressors on fish eggs and larvae and describes the biomarker responses of fish from locations with varying levels of pollution.
Atlantic salmon (Salmo salar, L) is an anadromous species contributing to major fishery catches and comprising a significant part of the aquaculturally produced fish for human consumption.
Eel of the genus Anguilla is an extraordinary fish, which due to its particular life cycle has fascinated biologists and physiologists ever since the pioneering works of Homer H.
Of all vertebrates, fish exhibit unparalleled diversity of sexual plasticity and flexibility, ranging from gonochorism to unisexualism, and exceptional patterns of functional hermaphroditism.
Volume IFor the fly fisher seeking to catch more and bigger trout, fishing nymphs--patterns that mimic the larval stage of mayflies--can be a surefire approach.
Volume IIAfter the mayfly family, detailed in Nymphs: The Mayflies, the fly fisher must know the caddisfly, stonefly, and midge populations just as well to catch trout that are keyed in on such insects.
The definitive guide from the renowned fly-fishing masterA handsome new illustrated edition of the classic by Art Flick, the man who gave American fly fishers their first useable, portable text for ';matching the hatch' at streamside.
Chasing the lightning-fast bonefish across the south Pacific, Florida, and the Caribbean is for many anglers a near obsession, and this is the handbook to such fly-fishing adventure.
Well over 300 freshwater fish species found in the regions rivers, lakes and dams feature in this fully revised third edition of Freshwater Fishes of Southern Africa.
Rabbitfishes (family Siganidae) are a vital yet often overlooked group of fishes in coral reef and seagrass ecosystems native to the tropical and subtropical Indo-Pacific region.
The Sparidae, commonly known as breams and porgies, is a family of fishes of the order Perciformes, and includes about 115 species of mainly marine coastal fish of high economic value, exploited and farmed for human consumption, as well as for recreational purposes.

Meer und Mensch – eine andere Geschichte des MittelaltersBauern und Ritter prägen unser Bild vom Mittelalter, und bei der mittelalterlichen Seefahrt denken wir an bauchige Hansekoggen und schnelle Wikingerschiffe.
Each organism has its own internal biological clock, which is reset by environmental cues (Zeitgebers), thus keeping it synchronized with the external environment.
The unprecedented level of diversity recorded among the clones of self-fertilizing gynogenetic unisexuals and self-fertilizing simultaneous hermaphrodites challenges current ideas on the predominant role of recombination in promoting evolution of biological diversity.
Dramatic changes in the environment, including habitat degradation and climate change, have focused attention on how individuals and populations respond to a shifting biotic and abiotic landscape.
An understanding of gonorynchiform morphology and systematic inter- and intra-relationships has proven vital to a better understanding of the evolution of lower teleosts in general, and more specifically of groups such as the clupeiforms (e.
Gills of healthy fishes are their lifeline to meet the challenges arising from their changing environment: oxygen gradient, alkalinity, temperature fluctuations and the added pollutants.
