FAO statistics on aquaculture production for 1998 have recently been released by the
Fishery Information, Data and Statistics Unit. A comparison between 1997 and 1998
aquaculture production data reveals that:
The total world production of aquatic species (excluding plants)
in 1998 increased by 2.04 mmt or 7.07 percent to 30.86 million metric tonnes. The value of
this production was
· Inland water aquatic animal production increased by 6.53 percent to 18.73 mmt with a 4.33 percent increase in value. The marine aquatic animal production increased by 0.89 mmt or 7.91 percent and was valued at US$ 22,310 million.
· Production of Pacific cupped oyster (Crassostrea gigas) increased by 15.61 percent to become the principal species farmed, overtaking silver carp (Hypophthalmichthys
molitrix) with a total production of 3.44 mmt. During the year, giant tiger prawn (Penaeus monodon) production increased by 8.80 percent to 578,000 mt.
· China, India and Japan retained their positions as the worlds first three largest aquaculture producers, while Bangladesh overtook Indonesia to become fourth by producing 0.58 mmt, which is an increase of over 70,000 mt or 13.87 percent.
· World seaweed production increased by 1.36 mmt or 18.88 percent to 8.57 mmt.
A detailed analysis of 1998 aquaculture production statistics will be made available to the FAN readers in future issues of FAN. The latest data can be accessed from http://www.fao.org/fi/statist/summtab/default.asp
