Techniques to monitor populations of feral swine (Sus scrofa) relative to damage control activities are needed on rangelands. Our objectives were to describe and assess a mark-recapture technique using tetracycline hydrochloride (TH) for monitoring feral swine populations. We established bait stations at study sites in southern and central Texas. During 1 d, we replaced normal soured corn bait with bait containing TH and counted the number of feral swine that consumed bait with observers. We conducted feral swine removal using box-style traps and helicopters, at which time we collected teeth for TH analysis. In southern Texas, we estimated population reduction to be 43%. In central Texas, we estimated population reduction of 31%. Our mark-recapture population monitoring technique would complement programs to manage feral swine populations and damage through lethal control./Se necesitan técnicas para monitorear poblaciones de cerdos ferales (Sus scrofa) para actividades de control de daños en pastizales naturales. Nuestros objetivos fueron describir y evaluar una técnica de marca-recaptura utilizando hidrocloruro de tetraciclina (HT) para monitorear las poblaciones de cerdos ferales. Establecimos estaciones con cebo en las a ́reas de estudio en el sur y el centro de Tejas. Durante un día, remplazamos el cebo de maíz fermentado con cebo conteniendo HT y con observadores, contamos el número de cerdos ferales que consumieron el cebo. En el sur de Tejas, se estimó una reducción del 43% de la población. En el centro de Tejas, la reducción estimada fue del 31% de la población. Nuestra técnica de monitoreo de marca-recaptura podría complementar programas de manejo de control letal de las poblaciones de cerdos ferales y los daños que los mismos ocasionan.
