This book was released on 2023-09-22 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide presents the egg and larval descriptions of 150 species of fishes belonging to 57 families, which are most likely to be present in plankton samples collected in the continental shelf and oceanic waters off northwest Africa. The guide is structured in two parts. The first introductory part describes the different applications of ichthyoplankton studies in fisheries research and management, and fish population ecology, the main sampling strategies, methods and gears, and the problems related to sample representativeness. It also describes the early life history of fishes, and how to identify them. A brief description of the hydrography of the study area is also presented. The second part of the guide features the species identification sheets. Each species sheet includes the following information: an illustration of the adult fish and information on its distribution, habitat, spawning season, and meristic characters; a description of the main features useful towards identifying the egg, yolk-sac and larval stages; and illustrations and photos of different larval stages. Finally, the guide provides a comprehensive list of references.
