DOWNLOAD EBOOKThis document provides a review, commentary and tabulations of the main trends that have occurred in exploitation of fisheries resources since the 1970s, largely as they are reflected in the FAO database on fishery landings, supplemented with selected information from the fishery literature. Reviews were prepared separately for the 15 main areas into which FAO divides the world's oceans for statistical purposes. They are then compared from a global perspective to reveal relative trends by species and areas, which are highlighted. Several special topics are reviewed, including tuna and tuna-like species, whales and dolphins, and environmental issues in fisheries.

DOWNLOAD EBOOKFisheries for highly migratory species are important in all oceans and semi-enclosed seas, except for polar regions. Fisheries for straddling fish stocks are much more localised, primarily occurring in a few regions where continental shelves extend beyond the 200 miles Exclusive Economic Zone (EEZ), while most fisheries for other high seas fishery resources are deep-water fisheries. This publication examines issues relating to the stocks of these resources, including information on their state of exploitation. Findings include that about 30 percent of the stocks of highly migratory tuna and tuna-like species, more than half of highly migratory oceanic sharks and nearly two-thirds of the straddling stocks and the stocks of other high seas fishery resources are overexploited or depleted. Although the stocks concerned represent only a small fraction of the world fishery resources, they are key indicators of the state of an overwhelming part of the ocean ecosystem which appears to be more overexploited than EEZs.

DOWNLOAD EBOOKThis publication updates the regular reviews of the state of the world's marine fishery resources, based mainly on official catch statistics throughout 2002 and relevant stock assessment and other complementary information available until 2004. It considers the global situation and major trends of world marine capture fish production, with detailed information for each FAO statistical area about catches and current state of exploitation, major trends and developments and stock assessment work undertaken in support of fisheries management. Other issues covered include: tunas and tuna-like species resources, world squid resources, deepwater fisheries, and long-term climate variability.

DOWNLOAD EBOOKThe total world catch of the major commercial tuna species (albacore, bigeye, bluefin, skipjack and yellowfin) has increased during the last 50 years (from 0.4 to 3.9 million tonnes), but the pattern of increase has varied among species, oceans and fishing gears. The Pacific Ocean has been the predominant region in the world catch, with catches from the Indian Ocean having exceeded those from the Atlantic Ocean in recent years. This publication examines historical trends in the catches of these tuna species and considers the causes of the variations.
