Hoop Nets. Nylon hoop nets had five 80-cm metal hoops, were double-throated, and had S-m
center leads. Two meshes sizes were used: 6 mmfor small and 25 mm for larger fish. Nets were
tarred. One large net without a lead was set in the current facing downstream. Leads were
typically tied to shore, and the hoops were set in 1 to 2 m of water perpendicular to shore. Nets
were set before dusk and checked twice daily, each morning and late afternoon. CPUE was
expressed as fish captured per 12-hour set (fish/12-h/set).

Minnow Traps. Custom collapsible minnow traps were constructed of 6-mm nylon net,
4-50-cm metal hoops, and 2 detachable spreader bars that kept the trap erect. The trap had
throats on each end, was tarred, and had a velcro flap for fish removal. Traps were generally set
among submerged tamarisk, in rocky cover, or along vertical rock formations. Traps were set
prior to dusk and checked each morning and afternoon. CPUE was expressed as fish captured
per 24-hour set (fish/24-h/set).
