Unusual Archaeology: Ancient Chambers and Ocean Tides (Part 1)

Fish trapping is an ancient practice, reaching across the globe from at least as far back as 11,000 years ago. It takes advantage of coastal tides and human-made chambers to catch and release fish. The simple but ingenious ancient fishing structures are built on two intertwining principles: the ocean can provide for us if we properly care for it. Archaeologists are mapping the possible locations of ancient traps. And on Penghu, a group of islands off of Taiwan, people are reviving the traditional tidal weirs, hoping to promote sustainable fishing and attract ecotourism.  Stay tuned for more from science journalist Kata Karáth in part two of our three-part Fascination series on unusual archaeology.
