World fisheries and aquaculture production
Shows the amount, in million tonnes, of fish taken by capture and aquaculture fisheries, between the years 1950-1999. Also included is a diagram showing the percentage of the different types of aquaculture in 1998.

Arctic pelagic food web
The marine animal food chain is very complex and multilayered as are most food chains. This is a quick reference to represent the complete food chain in regards to pelagic crustaceans and invertebrates.

Contribution of fish to human diet
The percentage of fish to the total human diet from various regions in the world. Based on statistics from 1987 to 1989. Fish is the last wild meal in the human diet, but roughly two-thirds of the world’s major stocks ar...

Ratio of discards from fisheries
The graphic shows the amount of discards in the fishing industry from 1988 to 1992. It is broken down into overall, fish, crustaceans and squid categories. Initiatives have been taken by several organisations, seeking to...

Harmful algal blooms in the West Central Atlantic, 1970-96
The graphic shows the trend of the number of harmful algal blooms in the Western Atlantic from 1970 to 1996. The excess growth of algae is often caused by pollution, and can have negative or fatal effects on some species...

Global fisheries stock
The graphic compares biomass to fish mortality to summarize the amount of exploitation on fish stocks globally. Fish is considered important to human diet, but roughly two-thirds of the world’s major stocks are now fishe...

World fisheries hotspots, 2004
The World’s most productive fishing grounds are confined to major hotspots, less than 10% of the World oceans. The maps shows annual catch (tonnes per km2) for the World’s oceans. Notice the strong geographic concurrence...

Trends in fisheries and aquaculture production (2000-2005)
The world's marine fisheries have stagnated or slightly declined in the last decade, offset only by increases in aquaculture production. A major reason why the decline has not become more evident is likely because of adv...

Indications of structural changes in the marine ecosystem, catch ratios of predatory and plankton feeding fish
Three-quarters of fish stocks are currently exploited to the maximum extent, if not excessively. The Northeast Atlantic Ocean continues to exhibit declining catches, as well as a shift towards fish at lower levels in the...

Fish diversity in freshwater systems
Although freshwater ecosystems such as rivers, lakes and wetlands occupy less than 2% of the Earth's total land surface, they provide a wide range of habitats for a significant proportion of the world's plant and animal ...
