Book Description
This guide is a tool for identifying the major resource groups likely to be encountered in the fisheries of Namibia. The introduction outlines the geographical, environmental and ecological factors influencing fisheries and the basic components of the fisheries of Namibia. Each resource group includes general remarks, an introduction to the technical terms and measurements pertinent to that group and a guide to species likely to be encountered in fisheries. Each species account provides scientific nomenclature; FAO common names, sizes notes on fisheries, habitat and biology, diagnostic features and illustrations. A pictorial index ; and some colour photographs of fishes caught mostly by trawl are included

Book Description
This multivolume field guide covers the species of interest to fisheries of the major marine resource groups exploited in the Eastern Central Atlantic. The area of coverage includes FAO fishing area 34 and part of 47. The marine resource groups included are bivalves, gastropods, chitons, cephalopods, stomatopods, shrimps, lobsters, crabs, hagfishes, sharks, batoid fishes, chimaeras, bony fishes and sea turtles. The introductory chapter outlines the environmental, ecological, and biogeographical factors influencing the marine biota, and the basic components of the fisheries in the Eastern Central Atlantic. Within the field guide, the sections on the re source groups are arranged phylogenetically according to higher taxonomic levels such as class, order, and family. Each resource group is introduced by general re marks on the group, an illustrated section on technical terms and measurements, and a key or guide to orders or families. Each family generally has an account summarizing family diagnostic characters, bi o logical and fisheries in formation, notes on similar families occur ring in the area, a key to species, a check list of species, and a short list of relevant literature. Families that are less important to fisheries include an abbreviated family account and no de tailed species in formation. Species in the important families are treated in detail (arranged alphabetically by genus and species) and include the species name, frequent synonyms and names of similar specie s, an illustration, FAO common name(s), diagnostic characters, biology and fisheries in formation, notes on geo graphical distribution, and a distribution map. For less important species, abbreviated accounts are used. Generally, this includes the species name, FAO common name(s), an illustration, a distribution map, and notes on biology, fisheries, and distribution. Each volume concludes with its own index of scientific and common names.

Book Description
The species of hake, making up the genus Merluccius, are commercially important and currently largely over exploited, with many stocks badly depleted and showing only limited signs of recovery. From the end of the 1990s, concepts such as sustainability, ecosystem-based approaches to fisheries management, a code for the responsible conduct for fisheries, governance and others have emerged or have been considered by politicians, stakeholders and society. Moreover, new tools for stock assessment have been developed. But many hake stocks of the genus Merluccius show no sign of restoration. Hakes: Biology and Exploitation brings together a wealth of important information on the biology and exploitation of hake and hoki stocks around the world. Each chapter provides an overview of the fisheries of each species in an ecological and environmental context, looking at stock distribution, characteristics of the environment, life history, reproduction, diet, growth, mortality, pricing and markets of each geographical region and the hake species found there. With chapters written by regional experts on hake species and included within Wiley-Blackwell’s prestigious Fish and Aquatic Resources Series, Hakes: Biology and Exploitation provides up-to-date and comparative information, including new approaches to fisheries management, for all those involved in fisheries management, aquatic ecology and biological sciences.

Book Description
A review of surveys carried out with the research vessel, Dr. Fridtjof Nansen, from 1975 to mid-1993 in the Indian, Atlantic and Pacific Oceans. The document includes an overview of survey methodology and a description of the development of the acoustic equipment used and the associated problems. Particular emphasis is placed on the surveys in the Arabian Sea.

Book Description
Easter Island (Rapanui) is the most remote inhabited island in the Pacific Ocean and the easternmost in Oceania. Much has been written on the origin of its first inhabitants and the enormous stone statues they carved and erected, but little exists on the island’s biota. Knowing that very few species of fishes had been reported for Easter Island, John Randall went there in 1969, with the support of the National Geographic Society, to study the fish fauna. He was joined during revisits in 1988 and 1989 by the island’s medical doctor, Alfredo Cea. They published the Rapanui names of fishes in 1984. The total number of Easter Island shore fishes to a depth of 200 meters is only 139 species. However, an astounding 21.7 percent are known only from the island, second only to the Hawaiian Islands in the percentage of endemic fishes. Forty-four new species of fishes have been described, of which 25 are in scientific papers by Randall or by Randall and coauthors. Shore Fishes of Easter Island puts all of these fishes in one beautifully illustrated book with introductory chapters (Historical Review, Zoogeography, Marine Conservation, Materials and Methods).

Book Description
This is a worldwide catalogue of the family Merlucciidae. Two subfamilies, Macruroninae and Merlucciinae, are recognized comprising four genera, Lyconodes, Lyconus, Macruronus, and Merluccius, and 18 species. Dichotomous keys are provided in the systematics chapter, enabling the identification of the hakes to the species level. Subfamilies and genera are also defined. The species are arranged in alphabetical order under each subfamily and genus to which they belong. The scientific name appears in bold at the head of each genus and species description, followed by the author, year of first description, and publication. Existing synonyms and FAO common names in English, French, and Spanish are also provided. For each species there is an illustration followed by ten sections: description or diagnosis with differential characters; additional information; geographical distribution; habitat and biology; size; fisheries; fishery statistics; state of resources; local names, if any; and bibliographical references (author and year). The review is completed by a series of color plates showing details of different elements (heads, otoliths, hyomandibulars, urohyals) for a quick and efficient diagnosis of the genera and species of Lyconus, Macruronus, and Merluccius
