World Review


Aquaculture and wild caught supplied the world with about estimated 142 million tons of fish in 2008 and of this, 115 million tons was used as human food, providing an estimated apparent per capita supply of about 17 kg, which is an all-time high

Aquaculture accounted for 46 percent of total food fish supply.

In 2008, per capita food fish supply was estimated at 13.7 kg if data for China are excluded. In 2007, fish accounted for 15.7 percent of the global population’s intake of animal protein and 6.1 percent of all protein consumed.


Globally, fish provides more than 1.5 billion people with almost 20 percent of their average per capita intake of animal protein, and 3.0 billion people with at least 15 percent of such protein.

China remains by far the largest fish-producing country, with production of 47.5 million tons in 2008 (32.7 and 14.8 million tons from aquaculture and wild caught, respectively).


Global wild caught production in 2008 was about 90 million tons, with an estimated first-sale value of US$93.9 billion, comprising about 80 million tons from marine waters and 10 million tons from inland waters. World wild caught production has been relatively stable in the past decades

Aquaculture continues to be the fastest-growing animal-food-producing sector and to outpace population growth, with per capita supply from aquaculture increasing from 0.7 kg in 1970 to 7.8 kg in 2008, an average annual growth rate of 6.6 percent.

While aquaculture production was less than 1 million tons per year in the early 1950s, production in 2008 was 52.5 million tons, with a first sale value of US$98.4 billion.

World aquaculture is heavily dominated by the Asia-Pacific region, which accounts for 89 percent of production in terms of quantity and 79 percent in terms of value. This dominance is mainly because of China’s enormous production, which accounts for 62 percent of global production in terms of quantity and 51 percent of global value.

The fish sector is a source of income and livelihood for millions of people around the world. Employment in fisheries and aquaculture has grown substantially in the last three decades, with an average rate of increase of 3.6 percent per year since 1980. It is estimated that, in 2008, 44.9 million people were directly engaged, full time or, more frequently, part time, in aquaculture or wild caught. This number represents a 167 percent increase compared with the 16.7 million people in 1980.



World Production



Employment in the fisheries sector has grown faster than the world’s population and then employment in traditional agriculture. The 44.9 million people engaged in the sector in 2008 represented 3.5 percent of the 1.3 billion people economically active in the broad agriculture sector worldwide, compared with 1.8 percent in 1980. Although Wild caught continue to provide by far the greater number of jobs in the primary sector, it is apparent that the share of employment in wild caught is stagnating or decreasing and increased opportunities are being provided by aquaculture.

One thought on “Aquaponics World Review

  1. Overfishing

    The proportion of marine fish stocks estimated to be underexploited or moderately exploited declined from 40 percent in the mid-1970s to 15 percent in 2008, whereas the proportion of overexploited or depleted increased from 10 percent in 1974 to 32 percent in 2008. The proportion of fully exploited stocks has remained relatively stable at about 50 percent since the 1970s. In 2008, 15 percent of the stock groups were estimated to be underexploited and able to produce more than their current catches. This is the lowest percentage recorded since the mid-1970s.

    The remaining 32 percent were estimated to be overexploited or depleted and, thus, yielding less than their maximum potential production owing to excess fishing pressure.

    This combined percentage is the highest in the time series. The increasing trend in the percentage of overexploited and depleted and the decreasing trend in underexploited and exploited stocks give cause for concern. Most of the stocks of the top ten species, which account in total for about 30 percent of the world marine wild caught fisheries production in terms of quantity, are fully exploited. Of the 23 tuna stocks, most are more or less fully exploited (possibly up to 60 percent), some are overexploited or depleted (possibly up to 35 percent) and only a few appear to be underexploited.

    Despite continued reasons for concern in the overall situation, it is encouraging to note that good progress is being made in reducing exploitation rates and restoring overfished fish stocks and marine ecosystems through effective management actions in some areas such as off Australia, on the Newfoundland-Labrador Shelf, the Northeast United States Shelf, the Southern Australian Shelf, and in the California Current ecosystems.
