Book (series)FAO species identification sheets for fishery purposes Southern Ocean: Fishing Areas 48, 58 and 88 (CCAMLR Convention Area)
Volume 1
1985Also available in:
No results found.This publication presents the marine living resources of the Southern Ocean considered to be of interest to fisheries or of major importance for the conservation of the Antarctic environment, in the form of a practical, illustrated field guide following the format of the by non well-established series of FAO Species Identification Sheets for Fishery Purposes. The major groups included are seaweeds, euphausiids, king crabs/stone crabs, bivalves, gastropods, cephalopods, hagfishes/lampreys, sharks , batoid fishes, bony fishes and marine mammals. Every group section includes an explanation of relevant technical terminology, general remarks, guides or keys to suborders, families or genera, and identification sheets for selected families and species. Identification sheets include an alpha-numerical family or species code, valid scientific names and synonyms still in use, proposed CCAMLR/FAO common names in English, French, Russian and Spanish, an illustration of the family or species in ques tion, a diagnosis, illustrated differential diagnoses of similar families or species, and information on size, geographical distribution and behaviour (with a map), and fisheries. The publication ends with a comprehensive alphabetical index of scientific and common names. -
DocumentSurvey of resources in the Indian Ocean and Indonesian area 1971
Also available in:
No results found.The resources of the tropical ocean derive from a number of separate ecosystems; for the present purpose there are five: the upwelling areas, offshore oceanic areas, coral seas, mangrove swamps, and coastal areas outside upwelling regions; Studies of the oceanic system lead to the conclusion that stocks of the four most valued tunas (yellowfin, bigeye, albacore, and southern bluefin) are fully exploited; other tunas and tuna-like fishes perhaps can be exploited: Spanish mackerel and especially s kipjack, whose estimated production is 100.000 tons; Coral seas are difficult to exploit, but production is likely to be high; there may be tertiary resources of Sardinella or mackerels over the whole coral area; Mangrove swamps are extensive, and their high productivity could be exploited with a variety of fish, shellfish, and crustacean cultures; the swamps need to be investigated for present resources; Upwelling areas and the associated offshore divergences are the most productive; the most p romising area for development is that off Northern Somalia and Southern Arabia, followed by the Malabar Coast and the Indonesian area. A fisheries survey should be mounted to catalogue resources of the three promising areas; surveys of pelagic resources with echo-sounders and purse-seines should be initiated all over the region but particularly in the upwelling areas. -
Book (series)Environmental management of fish resources in the Black Sea and their rational exploitation. Studies and Reviews. 1997
Also available in:
No results found.After a short introduction describing the environmental status of the Black Sea, information is presented on the marine algae, and the phytoplankton and zooplankton, including the events following the introduction of the predatory ctenophore, Mnemiopsis leydei. The existing historical information available on the resources of more than 14 commercial fish in the Black Sea is summarized, and placed in context with information on the marine environment together with an evaluation of the impact of e nvironment changes.
