Previously, researchers had excavated sinkers -- stones used to weigh downward nets for catching fish -- inwards Japan's Fukui Prefecture too South Korea's Cheongju city, but those discoveries were all dated dorsum to the Neolithic Era too believed to hold out but about 10,000 years old, Han said.
"This regain suggests humans inwards the Upper Paleolithic era were actively catching fish for their diet", he added.
The limestone sinkers, each weighing betwixt 14 to 52 grammes too amongst a diameter of 37 to 56 millimetres, had grooves carved into them too hence they could hold out tied to the bottom of nets too used to choose handgrip of pocket-sized fish such every mo minnows inwards shallow streams, he said.
Researchers also establish fossilized bones belonging to fish too other animals, every mo good every mo rock tools too flakes, within the Maedun cave, he said.
Prior to the South Korean find, the oldest line-fishing implements were believed to hold out line-fishing hooks, made from the shells of body of body of water snails, that were establish on a southern Japanese isle too said to engagement dorsum some 23,000 years.
