Fish Nutrition, Fourth Edition is an up-to-date, authoritative presentation of all key elements of the nutrition of fish and crustaceans. As aquaculture is rapidly expanding, more than 200 herbivorous and carnivorous species occupy a diverse range of ecological niches, and have therefore evolved to utilize a wide array of food sources. This new edition highlights these differences and covers the complexity and challenges associated with fish nutrition, addressing nutrient requirements to produce high-quality, healthful and sustainable resources, the essential nutrients for fish species, including proteins and amino acids, vitamins, minerals and essential fatty acids, a feed quality assessment, and fish pathology. Led by a team of international experts, this edition provides readers with new information on the use of high-throughput technologies in fish nutrition research, the role of feeds on the community structure of the microbiome, and advances in essential nutrient requirements.

Fish Physiology, Volume 38 in this ongoing series, examines how the inherent potential of fish to express traits of economic value can be realized through aquaculture. Topics covered include the regulation of the reproductive cycle of captive fish, shifting carnivorous fish towards plant-based diets, defining the challenges, opportunities and optimal conditions for growth under intensive culture (including in Recirculating Aquaculture Systems), enhancing immune function and fish health during culture, identifying and managing maladaptive physiological responses to aquaculture stressors, establishing welfare guidelines for farmed fish, phenotypic and physiological responses to genetic modification, Zebrafish as a research tool, and the aquaculture of air-breathing fish.

How does a mudskipper fish manage to “walk” on land? Why is the Hoatzin also known as ‘The Stinkbird’? And once the female Pipa toad has laid her eggs, where does she put them? The answers? The mudskipper can “walk” using its pectoral fins, the Hoatzin has a unique digestive system which gives the bird a manure-like odour, and the female Pipa Toad embeds its eggs on its back where they develop to adult stage. Illustrated throughout with outstanding colour photographs, Strange Animals presents the most unusual aspects of 100 of the most unusual species. The selection spans a broad spectrum of wildlife, from the tallest land living mammal, the giraffe, to the light, laughing chorus of Australian kookaburra birds, from the intelligence of the Bottlenose dolphin to octopuses that change colour when they dream to the slow pace of the three-toed sloth. Arranged geographically, the photographs are accompanied by fascinating captions, which explain the quirky characteristics of each entry. Including egg-laying mammals, birds, reptiles, amphibians, cannibalistic insects and other invertebrates, Strange Animals is a compelling introduction to some of nature’s most curious beasts.
