  1. Amphibians: Provide particular enclosure furniture for calling sites, breeding areas or egg laying sites

    A small, replicated, before-and-after study in 2004-2007 in Fiji found that the provision of egg laying sites including rotting logs and hollow bamboo stems Piper aduncum and various organic substrate in an enclosure resulted in successful breeding for two pairs of Fijian ground frogs Platymantis vitianus. Two egg clutches were found, one in a section of bamboo stem filled with damp soil substrate, and another under a moist rotting log on a mix of soil and leaf litter. A total of 39 froglets were raised after one year. A captive breeding program had been running for this species since 2004, but only one froglet was reared after three years of trying. From 2006-2007, five male and five female frogs were placed in a purpose built outdoor enclosure. Further detials in: Narayan E, Christi K. & Morley C.

  3. Captive breeding frogs

    In a continuation of a study at the University of the South Pacific, Fiji (Narayan et al. 2007, Narayan 2009), a small, replicated study (Narayan et al. 2007) found that adding natural structures to enclosures as potential egg laying sites resulted in the production of two clutches of eggs by Fijian ground frogs Platymantis vitianus. One clutch was laid underneath a moist rotting log in December and the other inside a bamboo stem lined with soil in January. Several of the five males and five females were observed in or near potential egg-laying sites throughout the breeding period. Natural structures were added as potential egg laying sites including rotting logs, hollow bamboo stems, coconut husks, rocks and decaying leaf litter. All material was sterilized prior to installation. Native plants were also added. Nocturnal activity was recorded using digital video surveillance cameras.
