People and the Environment

One of the ways in which the Calusa may have been able to intensify their food production was by means of large-scale fish weirs, wing dams, traps, and holding pens. Linear keys still visible today in the greater Charlotte Harbor estuarine system that was the heartland of the Calusa cannot be explained by modern dredging, and may be the remnants of elaborate large-scale fishing facilities. South Florida natives had several different kinds of watercraft, including seagoing vessels, small cargo canoes, and barges made of platforms connecting two parallel canoes.
