Aquaculture in China has increased in complexity over its 3000-yr history, with polyculture, animal husbandry and agriculture forming an integrated fish farming system. Artificial spawning increased production since 1936 from 500,000 to one million tons. The Pearl and Yangtze river deltas are the major centers, with the ample water supply, rich soil, mild temperatures and easy market access required. Although their integrated pond culture method is very efficient, demand is high and current produc- tion levels inadequate; problems with long-distance transportation and poor preservation techniques make expansion into new areas a pressing concern.

The author comments on major advances he foresees as a result of new ultrastructural and biochemical data, and argues for a revival of systematics in the universities. He details some of the specific changes and concludes that 'after systematic analyses of wider data sets a new classification for the inver- tebrates will be considered; however, the resulting scheme will be very different from that which we accept, follow, and teach today.'
