  abstract = {{A}rchaeology provides few examples of large-scale fisheries at the frontier between catching and farming of fish. {W}e analysed the spatial organization of earthen embankments to infer the functioning of a landscape-level pre-{C}olumbian {A}mazonian fishery that was based on capture of out-migrating fish after reproduction in seasonal floodplains. {L}ong earthen weirs cross floodplains. {W}e showed that weirs bear successive {V}-shaped features (termed '{V}s' for the sake of brevity) pointing downstream for outflowing water and that ponds are associated with {V}s, the {V} often forming the pond's downstream wall. {H}ow {V}s channelled fish into ponds cannot be explained simply by hydraulics, because {V}s surprisingly lack fishways, where, in other weirs, traps capture fish borne by current flowing through these gaps. {W}e suggest that when water was still high enough to flow over the weir, out-migrating bottom-hugging fish followed current downstream into {V}s. {F}inding deeper, slower-moving water, they remained. {R}eceding water further concentrated fish in ponds. {T}he pond served as the trap, and this function shaped pond design. {W}eir-fishing and pond-fishing are both practiced in {A}frican floodplains today. {I}n combining the two, this pre-{C}olumbian system appears unique in the world.},
