Trends in marine and freshwater populations Trends in marine and freshwater populations
The Marine Species Population Index provides an assessment of the average change over time in the populations of 217 species of marine mammals, birds, reptiles, and fish. The index represents the average value of six regional ocean indices. More pronounced declines are seen in the southern oceans, which is attributed to the fact that major losses and degradation of marine ecosystems in the industrialised world took place prior to 1970. Marine sp...

Trends in fisheries - freshwater and marine capture fishery Trends in fisheries - freshwater and marine capture fishery
The harvest of freshwater fish is likely to increase either through capture fisheries or aquaculture (otherwise known as 'fish farming'). This graphic shows inland capture fisheries trends at the national level for 1984 to 1997, and illustrates the ratio between the 1998 catch and the maximum recorded catch in various marine fishing zones around the world.

Shrinking of the Aral Sea: socio-economic impacts Shrinking of the Aral Sea: socio-economic impacts
Over the past 30 years, the Aral Sea in the former Soviet Union has shrunk to less than half of its original size. This graphic shows the Aral Sea as it was in 1960 and as it appeared in 2001. It shows that a former fishing zone is now a dry zone affected by salination. Areas that were previously food crops (partly irrigated) are now cotton and rice crops, widely irrigated. Other changes include the replacement of fish exports with fish imports, ...

Threatened species in Eastern European countries - freshwater fish Threatened species in Eastern European countries - freshwater fish
The information on the state of biodiversity from 22 Central and Eastern European and former Soviet countries was assembled on the occasion of the 5th Conference of Parties of the Convention on Biological Diversity in Nairobi May 15-26, 2000. It is a collaborative effort of the ENRIN national focal points of UNEP-GRID. This graphic shows threatened species in Eastern Europe, specifically freshwater fish.

Potential impact of sea level rise: Nile Delta Potential impact of sea level rise: Nile Delta
Rising sea level would destroy weak parts of the sand belt, which is essential for the protection of lagoons and the low-lying reclaimed lands in the Nile delta of Egypt (Mediterranean Sea). The impacts would be very serious: One third of Egypt's fish catches are made in the lagoons. Sea level rise would change the water quality and affect most fresh water fish. Valuable agricultural land would be inundated.

Coastal issues in the islands of Comoros and Mayotte Coastal issues in the islands of Comoros and Mayotte
With poverty and high population density this group of volcanic islands between Eastern Africa and Madagascar faces challenges in the management of the coastal environment. The islands are fringed by magnificent coral reefs, and the waters houses the rare coelacanth fish. Among the responses there have been initiatives to encourage ecotourism and the support in establishing the 400 km2 Mohéli Marine Park.

Total sturgeon catch in the Caspian Sea, 1932-2000 Total sturgeon catch in the Caspian Sea, 1932-2000
Pressure from the international community having raised awareness of its value as a bio-resource, the region is now struggling to save the sturgeon. To protect the vulnerable fish species more then 100 million sturgeon and bony fish juveniles have been released into the Caspian Sea in recent years.

Caviar imports to Japan, European Union and United States Caviar imports to Japan, European Union and United States
The Caspian area is the world’s main producer of wild caviar (83% in 2003) and supplies the three largest markets, the European Union, Japan and the USA. The construction of several hydroelectric power plants and dams along the Volga river significantly altered the flow of water into the delta and destroyed about 90% of the sturgeon’s spawning grounds, which can be as far as several hundreds of kilometres upstream. This graphic displays the repor...

Oil pollution in Azerbaijan Oil pollution in Azerbaijan
There are hundreds of abandoned oil wells in Azerbaijan, and thousands in Kazakhstan, many of which have been submerged by the rising sea. There are reports of big leaks into the water, killing waterfowl and fish. Thousands of hectares of soil on Azerbaijan’s Apsheron peninsula are unsuitable for agricultural use.
