Turtles (Cheloniidae: Chelonia Mydas) At
Setiu, Terengganu, Malaysia.
Masters thesis, Universiti Sains Malaysia.
Abstract
This study conservation of green sea turtles (Chelonia mydas) at Setiu was
studied by determining their distribution, nest characteristics, clutch size, nesting
morphology of the nesting green turtles, false crawl attempts, successful nesting
attempts and emergence hour. Hatchery management was also facilitated by
measuring the successive hatching rate, duration of incubation, egg condition,
hatchlings’ growth and hatchlings’ carapacial scutes variation. This study also
assessed socio-demographic aspect on the trends of consuming turtle eggs.
Secondary data on nesting ecology and behaviour were collected from 2007 to 2012.
Data on successful hatching rate and days of incubation were collected from 2009 to
2012. Hatchlings’ growth and carapacial scute variation were determined in the year
2012. Survey forms were collected from the communities in Setiu to assess their
level of awareness regarding green sea turtle conservation. Telaga Papan has
significantly the highest distribution of green marine turtle nesting than the other five
beaches (ANOVA, F 5, 42 = 8.87, p< 0.0001). The highest number of successful
nesting attempts was in 2012 (mean = 28.71 ± 6.58). There was no correlation
between size of the female turtles and the number of eggs (rs = 0.23, p = 0.14). The
majority of the turtles landed between 1200h and 0159h (23%). There was a strong
correlation between successful nesting attempts with false crawls (rs= 0.88, p= 0.02).
Results show that there was a significant difference in successive hatching rate
between the years (F3, 618 = 5.05, P = 0.002). There was no significant difference for
successive hatching rates among the beaches over the four years (F4, 618= 1.06, P =
0.39).
