Red-eared terrapin: Direct removal of adults Control of Freshwater Invasive Species

A replicated field study conducted in 2008, in the Arga River, Spain (Valdeón et al. 2010) found that modified Aranzadi turtle traps were effective at trapping red-eared terrapin Trachemys scripta elegans and Trachemys scripta scripta but did not eradicate the populations, and that these traps performed better than modified Bolue traps, and fish-baited traps, which trapped very few terrapins.   The modified Aranzadi turtle traps caught an average of 70% of observed terrapins.  During five months of spring and summer 2008, one of each of the three trap types was set in each of two areas of the Arga River, Spain.  On separate dates, one of each trap type was also set in 11 different water bodies.  The baited traps were visited on consecutive days, while basking traps were checked weekly during five months of spring and summer of 2008.
