Book A guide to the eggs and larvae of 100 common Western Mediterranean Sea bony fish species

Download or read book A guide to the eggs and larvae of 100 common Western Mediterranean Sea bony fish species written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-11-16 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book The Eastern Mediterranean as a Laboratory Basin for the Assessment of Contrasting Ecosystems

Download or read book The Eastern Mediterranean as a Laboratory Basin for the Assessment of Contrasting Ecosystems written by Paola Malanotte-Rizzoli and published by Springer Science & Business Media. This book was released on 1999-02-28 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the outcome of a NATO Advanced Research Workshop on "The Eastern Mediterranean as a laboratory basin for the assessment of contrasting ecosystems" that was held in Kiev, Ukraine, March 23-27, 1998. The scientific rationale of the workshop can be summarized as follows. The Eastern Mediterranean is the most nutrient impoverished and oligotrophic large water body known. There is a well-defined eastward trend in nutrient ratios over the entire Mediterranean that starts at the Gibraltar Straits and, through the western basin, proceeds to the Ionian and Levantine Seas. Supply of nutrients to the entire Mediterranean is limited by inputs from the North Atlantic and various river systems along the sea. The unique feature of the Mediterranean is the presence of an eastward longitudinal trend in available nitrate/phosphate ratios. This apparently induces a west-to-east variation in the structure of the pelagic food web and trophic interactions. In this context the Mediterranean, and in particular its Eastern basin, provides probably a unique platform to explore the hypotheses related to the suggested phosphate-limitation on production and to the shift between "microbial" and "classical" modes of operation of the photic food web. The major exception of the overall oligotrophic nature of the Eastern Mediterranean is the highly eutrophic system of the Northern Adriatic Sea. Here, during the last two decades the discharges of the northern rivers (especially of the Po), together with municipal sewage, have led to a very marked increase of nutrients and subsequent imponent eutrophication events.
