Fish communities and populations during the post-Saladoid period (AD 600/800–1500), Anguilla, Lesser Antilles

Analysis of vertebrate remains from two archaeological sites indicates human exploitation did not adversely impact fish populations and fish communities during the post-Saladoid period (AD 600/800–1500) on Anguilla, northern Lesser Antilles. Barnes Bay (AL-14-BB) and Sandy Ground (AL-03-SG) are contemporaneous, large village sites located within 10 km of one another in similar terrestrial and adjacent marine environments. Despite substantial human population growth and increasing social complexity by AD 1000, residents at these sites exploited the same marine fishes and captured similar relative frequencies of fish families throughout the occupational sequence. No evidence of overfishing is found, either as a decline in the mean size of members of three fish families or in the ranges of size of these families through time. Evidence of a greater use of some members of a fourth family is found at Sandy Ground during the later post-Saladoid. It is likely that economic or social factors, rather than environmental change, contributed to this increase. By identifying specific locations where human over-exploitation did or did not impact fisheries, we may begin to distinguish patterns and characteristics which led to unsustainable fishing in the past at other sites, or in other circumstances.
