Abstract: Summary A new fishery has been developing in the Amazon that uses dolphin and caiman species as bait to catch piracatinga (Calophysus macropterus), having thus the potential to cause adverse food‐web impacts; however a lack of basic understanding of this fishery is a limitation to the necessary management action. Interviews with fishers and analyses of fishing records in Brazil were used for the study, including harvest methods, types of baits used, commercialization chains, and the rate of increase of piracat… Show more

“…In one floodplain system in the Central /Brazilian Amazon, take levels (estimated at 1650 dolphins per year, da Silva et al, 2011) likely exceed sustainable limits, as indicated by decreased survival rates (Mintzer et al, 2013) and a marked population decline (i.e., a per annum mean reduction of 10% since 2000; da Silva et al, 2011). Although tucuxi are rarely targeted, if they become entangled in fishing gear, the carcasses are utilized as bait (Iriarte and Marmontel, 2013a,b;Brum et al, 2015).…”

“…In response to pressure from conservation groups, the Ministry of the Environment in Brazil announced a 5-year moratorium on the selling and trade of piracatinga effective January 2015 (Brum et al, 2015). Because piracatinga is transported to and handled in large processing facilities, monitoring for compliance and enforcement are expected to be relatively straightforward endeavors.…”
