| 抄録: | A statistical analysis was made on Chelonia mydas incubation data for a turtle nesting beach (Mak Kepit, Terengganu) and a hatchery (Chendor, Pahang) in Peninsular Malaysia. Full and undisturbed clutches on the natural beach brought high emergence success of 84.75% (range 79.8-89.0%) for a 4-year period (1997-1998 and 2000-2001). Mean values were c.a. 40% higher than translocated full clutches in the hatchery (1997-1998). There was no significant difference in the emergence success between split and full clutches in both 1997 and 1998 (ANOVA : df = 1, F = 0.188, P<0.05). From this finding and cost of hatchery operations, it is recommended that hatchery should incubate full clutch eggs. |
