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.

Tony Hutson illuminates the nocturnal world of bats and examines how they have adapted to habitats in every corner of the world. Beginning with the fossil record and what it reveals about their relationship to other mammals, Hutson discusses their unique aerodynamics and their extraordinary feats of echolocation. He discusses their life cycle, diet and foraging strategy, breeding, roosting, and migration patterns as well as their predators, parasites, and man-made threats to their ecosystem. Bats are long-lived mammals which can form enormous colonies containing tens of millions of creatures, a concentration of mammals paralleled only by human cities. Topically, the book looks at the viruses harboured and tolerated by bats and their impact on humans. The book also contains an appendix of bat families and subfamilies and gives details of the number of genera or species, distribution, size, roost habitat and diet.
