Tidal fish trap (Visvywer). Thought by Avery (1975) to have been built after the advent of prehistoric pastoralism about 2000 years ago, tidal fish traps (Plate 5) are archaeological features of the south coast. Several examples are known to have existed in False Bay but were converted into tidal swimming pools during the late 19th and early 20th centuries, other examples have survived at Soetwater on the Peninsula. The traps were built by piling stones in the intertidal zone to create an enclosure or dam with steep inner sides and gradually inclined exteriors. Shoals of fish, trapped in the enclosure at low tide could then be speared or gathered. The traps were effective at spring or high tides but had to be periodically maintained to be useful. There are accounts of tidal fish traps that were still successful, and being maintained by communities in the early 20th century. Significance: A locally significant archaeological feature that has particular group value in association with other large Late Stone Age shell middens at Buffelsbaai. The fish trap, given adequate explanation also has the potential to contribute to environmental education in terms of the way that people exploited marine resources in the past.
