Book Description
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.

Book Description
A thorough understanding of planktonic organisms is the first step towards a real appreciation of the diversity, biology, and ecological importance of marine life. A detailed knowledge of their distribution and community composition is particularly important since these organisms are often very delicate and sensitive to change, and can be used as early indicators of environmental change. Natural and man-induced modification of the environment can affect both the distribution and composition of plankton, with important ecological and economic impacts. Marine Plankton provides a practical guide to plankton biology with a large geographic coverage spanning the North Sea to the north-eastern Atlantic coast of the USA and Canada. The book is divided into three sections: an overview of plankton ecology, an assessment of methodology in plankton research covering sampling, preservation, and counting of samples, and a taxonomic guide richly illustrated with detailed line drawings to aid identification. This is an essential reference text suitable for senior undergraduate and graduate students taking courses in marine ecology (particularly useful for fieldwork) as well as for professional marine biologists. It will also be of relevance and use to environmental scientists, conservation biologists, marine resource managers, environmental consultants, and other specialised practitioners.

Book Description
This guide presents the egg and larval descriptions of 100 species of fishes belonging to 55 families, which are most likely to be present in plankton samples collected in the continental shelf and oceanic waters of the Western Mediterranean Sea. The guide is structured in two parts. The first introductory part describes the different applications of ichthyoplankton studies in fisheries research, the main sampling strategies, methods and gears, the early life history of fishes and how to identify them. A brief historical account of ichthyoplankton identification studies in the Mediterranean Sea is also provided. The second part of the guide contains the identification sheets of the species. Each species sheet includes the following information: illustration of the adult fish and information on its habitat and spawning season; description of the main features useful towards identifying the egg, yolk sac and larval stage of each fish species; illustrations and (when available) photos of the different life stages.
