A fish species can be called mesopelagic if it spends the day in the mesopelagic zone. The mesopelagic zone has been defined in different ways based on depth, temperature and light regimes. For the present purpose, depth seems to be the best criterion and mesopelagic fish can thus be defined as species generally spending the day at depths between approximately 200 and 1 000 m. Generally they perform a diel migration, coming to the upper 200 m or even to the surface during the night. The present report briefly reviews the systematics ecology and life history of important groups of mesopelagic fish. Further, some methods used for abundance estimation of these fish are described and discussed. The bulk of the report reviews the present knowledge of abundance and species composition of mesopelagic fish in each of the FAO statistical areas. Although the data in most cases are few, an attempt has been made to give tentative estimates of the biomass and production in the various areas. When available, information on the life history of the most important species in each area is also given.

This book deals with the bottom-living fishes of the world's largest ecosystem, the deep-sea. After a brief review of the oceanographic setting, the diversity and ecology of this unique ichthyofauna are considered in detail. The book goes on to deal explicitly with slope fisheries, both developed and developing. The interaction of the ecology of the species involved (examples include orange roughy, grenadier, Greenland halibut and black scabbardfish) with fishing practices and management regimes is then discussed. An ecological framework for management is necessary for the resources to be sustainable it is argued, rather than simply extending approaches used on the Continental Shelf to the deep-sea.

No environment on Earth imposes greater physical and biological constraints on life than the deep oceanic midwaters. Near-freezing temperatures, the absence of sunlight, enormous pressure, and a low food supply make habitation by any living thing almost inconceivable. Yet 160 species of anglerfishes are found there in surprising profusion. Monstrous in appearance, anglerfishes possess a host of unique and spectacular morphological, behavioral, and physiological innovations. In this fully illustrated book, the first to focus on these intriguing fish, Theodore W. Pietsch delivers a comprehensive summary of all that is known about anglerfishes—morphology, diversity, evolution, geographic distribution, bioluminescence, and reproduction.

Erratum: Table 11.1 on page 241 has been mis-set. The entries for the phyla Annelida, Bryozoa, Cnidaria, Echiura, Mollusca, Placozoa, Porifera and Rotifera should all be moved one column to the right. The deep sea environment is the most extensive on our planet. Its denizens are normally unseen but whenever they are exposed to view they are regarded as bizarre aliens from a different world. The Biology of the Deep Ocean takes a close look at this apparently hostile world and explains how its inhabitants are exquisitely adapted to survive and flourish within it.

This book breaks new ground with the integration of geography, oceanography, plankton and benthic biology, as well as fish, to present a comprehensive account of the ecology of the tropical ocean. Proceeding from a description of the geomorphology, sediments, and vegetation of tropical continental shelves and the oceanography of tropical regions, the authors describe the benthos, plankton, and fish communities of tropical seas. An examination of the production of plant and animal life in tropical oceans is presented together with the numerical population biology of fish and invertebrates.

During the past decade, man's centuries-old interest in marine me teorology and oceanography has broadened. Ocean and atmosphere are now treated as coupled parts of one system; the resulting interest in air-sea interaction problems has led to a rapid growth in the sophistication of instruments and measurement techniques. This book has been designed as a reference text which describes, albng with the instruments themselves, the accumulated practical experi ence of experts engaged in field observations of air-sea interac tions. It is meant to supplement rather than replace manuals on standard routine observations or instnunentation handbooks. At the inception a textbook was planned, which would contain only well tested methods and instruments. It was quickly discovered that for the book to be useful many devices and techniques would have to be included which are still evolving rapidly. The reader is therefore cautioned to take nothing in these pages for granted. Certainly, every contributor is an expert, but while some are back ed up by generations of published work, others are pioneers. The choice of topics, of course, is debatable. The types of observa tions included are not exhaustive and topics such as marine aero sols and radio-tracers are omitted, as was the general subject of remote sensing, which was felt to be too broad and evol ving too rapidly. The guideline adopted in limiting size was maximum use fulness to 'a trained experimentalist new to the field'.
