2 December 2014/Accepted: 2 October 2015 ABSTRACT Egg clutches of Chalcorana labialis were collected from their natural habitat
at Sungai Junjong, Kedah, between March 1998 and February 1999.
Egg clutches were typically encountered in temporary pools, rock
pools and isolated pools at the edge of the river. In the laboratory
several reproductive parameters including clutch size, egg diameter,
hatching and metamorphosis rates were measured. The mean ± SD (range, N) of clutch size, egg diameter,
hatching and metamorphosis rates of C. labialis were 1365.4
± 421.1 (787-2100, 10) eggs, 1.36 ± 0.15 (1.12-1.68, 20) mm, 97.30
± 0.99% (95.87-98.86, 10) and 4.15 ± 0.74% (3.1-5.8, 10), respectively.
These results indicated that the successfully rate of larvae to
become froglets is relatively low, although it was reared in the
laboratory. To keep survived, almost all species of frogs produced
eggs in a large quantity. Keywords: Clutch size;
egg diameter; frog; hatching; metamorphosis ABSTRAK Kelompok telur Chalcorana labialis telah dikutip dari habitat semulajadinya di
Sungai Junjong, Kedah, antara Mac 1998 dan Februari 1999. Kebanyakan
daripada kelompok telur tersebut ditemui di lopak sementara, lopak
batu dan lopak-lopak terpisah yang berhampiran dengan sungai. Di
makmal beberapa parameter pembiakan termasuklah saiz kelompok telur,
diameter telur, peratus menetas dan metamorfosis telah diukur. Min
± SD (julat, N) bagi saiz kelompok
telur, diameter telur, peratus menetas dan metamorfosis bagi C.
labialis masing-masing ialah 1365.4 ± 421.1 (787–2100, 10) telur,
1.36 ± 0.15 (1.12–1.68, 20) mm, 97.30 ± 0.99% (95.87–98.86, 10)
and 4.15 ± 0.74% (3.1–5.8, 10). Hasil kajian menunjukkan peratus
larva yang berjaya menjadi anak katak adalah amat rendah, walaupun
telah dipelihara di dalam makmal. Untuk meneruskan kemandirian,
hampir kesemua spesies katak menghasilkan telur dalam kuantiti yang
besar. Kata kunci: Diameter telur; katak; kelompok telur; menetas; metamorphosis REFERENCES
