Improvement in ex-situ egg hatchability of Fijian ground frog Platymantis vitianus by laboratory incubation of egg masses, University of the South Pacific, Suva, Fiji
Breeding of the endangered Fijian ground frog Platymantis vitianus coincided with the Fijian wet season
(December/January) during captive management in a purpose-built outdoor enclosure at the University of the South Pacific, Fiji. Two fertile egg masses (around 40 eggs in each) were laid. A low hatchability of 10.8% (n = 40) was recorded for the first egg mass found, which was left in the outdoor enclosure to develop. The second egg mass was taken into the laboratory for incubation where hatching success was very much higher at 87.5% (n = 42). The hatchability difference was attributed to appropriate incubation techniques in the laboratory which reduced infection and hence mortality, of the eggs
