Oral tradition in China tells of the culture of the common carp, "Cyprinus carpio", as long ago as 2000–2100 BCE (around 4,000 years BP), but the earliest significant evidence lies in the literature, in the earliest monograph on fish culture called "The Classic of Fish Culture", by Fan Li, written around 475 BCE (c.2475 BP). Another ancient Chinese guide to aquaculture was by Yang Yu Jing, written around 460 BCE, showing that carp farming was becoming more sophisticated. The Jiahu site in China has circumstantial archeological evidence as possibly the oldest aquaculture locations, dating from 6200BCE (about 8,200 years BP), but this is speculative. When the waters subsided after river floods, some fish, mainly carp, were trapped in lakes. Early aquaculturists fed their brood using nymphs and silkworm faeces, and ate them.
