The tucuxi dolphin is regularly caught accidentally in gillnets of large fishing trawlers, and is the most common cetacean in the by-catch of coastal fisheries in the south Caribbean Sea. Intentional hunting appears to be rare, but does take place for meat to eat, for blubber to be used as shark bait, and for the genital organs and eyes which are sold as love amulets (1). A major potential threat is a proposal for the construction of hydroelectric dams, which would cause population fragmentation and increased inbreeding, as well as the extinction of the migratory fish that constitute the diet of the freshwater tucuxi dolphin (2). Pollution from heavy metals, banned pesticides and noise are also concerns, as is habitat loss (1).
