Total trade in sturgeon caviar, 1999-2003 Total trade in sturgeon caviar, 1999-2003
The caviar trade reportedly fell by about 70% between 1999 and 2003 but there is still every reason to monitor development of the sturgeon population and keep it on the list of endangered species. However it is not clear to what extent the temporary ban on caviar exports has boosted well established illegal domestic and international trafficking, obviously not accounted for in the official figures.

Fish catch and production Fish catch and production
Fishing activities have various negative impacts on marine ecosystems. The greatest cause for concern is the rapid depletion of fish population due to extensive commercial fishing. In 2002 72% of the world’s marine fish stocks were being harvested faster than they can reproduce. Bycatch – the harvest of fish or shellfish other than the species for which the fishing gear was set – accounts for a quarter of the total catch (27m tonnes in 2003) an...

EU fishing agreements to West and Central African countries EU fishing agreements to West and Central African countries
Fisheries activities by European Union countries in the seas of West Africa contribute EUR 120 million annually in government revenues. A part of the contribution is set for “targeted actions” to promote local resource management and sustainable development. For some of the poorest countries under these agreements – like Guinea-Bissau, the EU payments represent a significant part of the government revenues.

Trend in mean depth of catch since 1950 Trend in mean depth of catch since 1950
Fisheries catches increasingly originate from deep areas. Over the years due to depletion in fish stocks the fishing industry has resorted to fishing at greater depths and increasing the damage to fish stocks and the ocean floor.

Marine, coastal, and island systems Marine, coastal, and island systems
Marine systems are the world’s oceans. For mapping purposes, the map shows ocean areas where the depth is greater than 50 meters. Global fishery catches from marine systems peaked in the late 1980s and are now declining despite increasing fishing effort.

Collapse of Atlantic cod stocks off the East Coast of Newfoundland in 1992 Collapse of Atlantic cod stocks off the East Coast of Newfoundland in 1992
From the late 1950s, offshore bottom trawlers began exploiting the deeper part of the stock, leading to a large catch increase and a strong decline in the underlying biomass. Internationally agreed quotas in the early 1970s and, following the declaration by Canada of an Exclusive Fishing Zone in 1977, national quota systems ultimately failed to arrest and reverse the decline.

Estimated global marine fish catch, 1950 -2001 Estimated global marine fish catch, 1950 -2001
Fishing production dramatically increase through the century peaking in late 1980s. At this time there were major declines in several fish populations in different areas of the world. The catch reported by governments is in some cases adjusted to correct for likely errors in data.

Protected areas, Arctic and Antarctic Protected areas, Arctic and Antarctic
Protected areas are very important for conserving biodiversity. In these areas, human activities are managed to achieve specific conservation goals, for example, to protect a certain species or to conserve a representative habitat or ecosystem. The Arctic has many terrestrial protected areas, but is generally lacking in marine protected areas (MPAs). As the climate warms and the sea ice melts, there will be greater access for activities such as f...

Fisheries in the Southern Ocean Fisheries in the Southern Ocean
Fisheries, together with tourism, represents a major economic activity around Antarctica. In the old days whales were hunted for oil - these days fish and krill are captured for fish meal and human consumption. The areas in the Southern Atlantic are vastly more productive, and this is where most of the fish is caught. The top fishing vessels hail from Japan, Ukraine and Poland. Worth mentioning is that these figures are still small compared to th...

Trends in local meat-and fish in NWT Trends in local meat-and fish in NWT
The harvest of natural resources is a key feature of traditional lifestyles and economies throughout the Arctic, and a continuing reliance on it as a mainstay of indigenous existence in the north is evident. According to Northwest Territories, Canada (NWT) Labour surveys, about 37–45% of NWT residents went hunting or fishing in 2002. This has changed little since the first survey in 1983, and is high compared to southern Canada. About 40–60% of...

Red king crab native and invasive distribution Red king crab native and invasive distribution
The red king crab is native to the Okhotsk and Japan Seas, the Bering Sea, and the northern Pacific Ocean, where it is an important economic resource. In Alaskan waters, red king crabs have historically been the second most valuable species to fishermen after salmon, although since the 1980s overharvesting has led to the closure of some areas to fishing. The king crab also has an invasive distribution in the Barents Sea. Since its introduction in...

Expected impacts of climate change in 2050 Expected impacts of climate change in 2050
It is expected that by 2050 there will be threats to ecosystem services in the Andes and Mexico, in the Central American and Caribbean sub-regions, and in southeastern Brazil, while there will be negative effects on fishing in the Pacific coastal areas of Peru and Chile. The decrease in precipitation will have adverse effects on agricultural yields in several regions and countries throughout the continent. Particularly noteworthy within Latin Ame...

Coastal Arctic food web (drift ice) Coastal Arctic food web (drift ice)
The coastal Arctic food web is closely related to drift ice conditions and seasonal use of shorelines by both terrestrial and sea mammals. Numerous species depend upon each other and the transport of food to and from the marine areas to the coast and inland. Indigenous peoples use most of the food chain and traditionally use both environments for hunting, fishing and gathering.

Economy of the Arctic, by sector Economy of the Arctic, by sector
The largest economies in the Arctic belong to Alaska (US) and Russia, mainly because of mining and petroleum activity. Regions that are still heavily dominated by more traditional subsistence activities, such as hunting and fishing, in Greenland and in Northern Canada, have much lower gross products. Similarly, reindeer herding in Russia and Scandinavia is of substantial importance to the livelihoods and lifestyles of reindeer herders like the Sa...

Traditional practices, infrastructure and development Traditional practices, infrastructure and development
Indigneous peoples have lived in Arctic for thousands of years, and continue to depend upon the natural resources of the region today. Their traditional subsistence practices include hunting, trapping, fishing and reindeer herding. All of which are conducted in a sustainable manner; that is, in a way that does not lead to long-term or large-scale degredation of the environment. However, the balance they have achieved with the environment through...

Fishing yield Fishing yield
Three-quarters of the world’s fish stocks are currently exploited to the maximum extent, if not in excess (FAO, 2000). This exploitation has had the following impacts: - A growing variety of fishery products are being exploited. Commercial fishermen are targeting progressively smaller species at lower levels of the food chain because the main predator species are being depleted. - Most of the world’s main fishing areas are close to full exploit...

The disappearance of the Aral Sea The disappearance of the Aral Sea
The demise of the Aral Sea in central Asia was caused primarily by the diversion of the inflowing Amu Dar’ya and Syr Dar’ya rivers to provide irrigation water for local croplands. These diversions dramatically reduced the river inflows, causing the Aral Sea to shrink by more than 50%, to lose two-thirds of its volume, and to greatly increase its salinity. At the current rate of decline, the Aral Sea has the potential to disappear completely by 20...

Coral reefs at risks Coral reefs at risks
There are two distinct regions in which coral reefs are primarily distributed: the Wider Caribbean (Atlantic Ocean) and the Indo-Pacific (from East Africa and the Red Sea to the Central Pacific Ocean). - The diversity of coral is far greater in the Indo-Pacific, particularly around Indonesia, the Philippines, and Papua New Guinea. Many other groups of marine fauna show similar patterns, with a much greater diversity in the Indo-Pacific region. ...
