Aquaculture is the production, processing, and marketing of biological organisms from aquatic systems. It is remarkable to note that aquaculture engineering is not new yet the minor research effort has been applied because man finds creatures that dwell in an aquatic world more difficult to understand than ones which breathe in air. It is evident that aquaculture is an expensive practice and requires long-term dedications which can only be afforded by developed countries. The organization of the book has emphasized on the rich array of aquacultural engineering and represented in a simplest possible way. With this recent edition, we aim to serve a wide range of readers' groups with the intention of contributing towards technological advancement in aquacultural engineering. Salient Features This recent edition attempts to explore the technological advancement in the field of aquaculture engineering in an authoritative and concise manner. The book is intended to serve wide readers including practicing aquacultural engineers, biologists, hatchery managers, aquaculturists and other concerned fishery experts, researchers, and academician. The recent edition provides great focus on the updated information till the date of publication. The content is provided with numerous tables, flow charts, line diagrams and colored photographs or illustrations to enhance the learning of complex aquacultural mechanisms.
