Book Description
Prediction equations correlating density of fingerling rainbow trout with growth, yield, and food use efficiency indicated that ammonia nitrogen resulting from high fish densities wes responsible for reductions in all three factors. These predictable density-dependent responses present fish-culturists with alternatives of density selection for evaluation and attainment of specific goals. In examples, fish-culturists, by manipulating density, could achieve rapid growth, produce the maximum weight possible, balance yield with cost, optimize fish quality, or combine two or more of these goals.

Physiological Adaptations to Swimming in Fish
Author: Josep V. Planas
Publisher: Frontiers Media SA
ISBN: 2889452468
Category :
Languages : en
Pages : 90
Book Description
Swimming is an integral part of the life history of many fish species as is intimately linked with their ability to express feeding and predator avoidance behaviors, habitat selection and environmental preferences, social and reproductive behaviors as well as migratory behaviors. Therefore, swimming is an important determinant factor of fitness in a true Darwinian sense and, not surprisingly, swimming performance has been often used as a measure of physiological fitness in fish. The main aim of this Research Topic is to showcase some of the current studies designed to improve our understanding of the physiological energetic and metabolic requirements of swimming and of the adaptive responses to swimming in fish.

The Biology of Sole
Author: José A. Munoz-Cueto
Publisher: CRC Press
ISBN: 1498727840
Category : Nature
Languages : en
Pages : 396
Book Description
This book reviews up-to-date knowledge on the biology of sole (Solea senegalensis and S. solea). These flatfish species are increasingly important in Europe both from the ecological and production point of view. This book is divided into two sections: A. general fisheries, aquaculture and engineering overviews; B. physiological, developmental, rhythmic, welfare and genetic aspects which will be of immense interest for the aquaculture industry. Experts, from both academia and research institutes, provide their expertise on sole biology.
