Zusammenfassung:Adult Gambusia prey on young Gambusia in experimental chambers much less than suggested in the existing literature. Approximately half of the young confined in aquaria with an adult survive a 30-day experimental interval. Most of the predation is by females and some species such as Gambusia gaigei are far more predacious than others. The Big Bend population of Gambusia affinis is much less predacious on young Gambusia than are other species of Gambusia.
