Seaturtle body measurement and tagging
Adult female nesting seaturtle body measurement and flipper tag attachment were done after the oviposition was done. Morphometric measurements were done
in two ways, Curve Carapace Length and Width CCLW and Straight Carapace Length and Width SCLW Bolten, 1999 see Figure 3. Measurements over the
carapace curve CCL in adults are 3 to 4 cm larger than straight carapace length SCL Marquez-M, 1990. CCLW was measured by using flexible measuring
tape while Straight Carapace Length and Width SCLW was measured by using stiff measuring tape and stick.
Straight carapace length and width SCLW Bolten, 1999 of 21 nesting green turtles and curved carapace length and width CCLW Bolten, 1999 of 25
green turtles were measured during the field work. Additional data of curved carapace length and width CCLW and population data of nesting green turtle in
2010 n = 104 and 2011 n = 36 were obtained from the UPTD Konservasi Penyu Pangumbahan. Hatchlings carapace length and width n = 58 were
measured by using SCLW as suggested by Bolten 1999. Hatchlings body weight n = 55 was measured by using digital scale accuracy ± 0.01 gram.
In addition, we also investigated hatchlings straight carapace length - width and body weight. Straight carapace size was measured using a caliper with
accuracy of ± 0.1 cm. The main interest for this measurement was to know whether it was safe to sample hatchlings body fluids for sex determination. Sex of
seaturtle hatchlings can not be defined by looking at external anatomy. There are several methods to do so, both direct and indirect method. Conventional method
was to look at the gonad by dissecting. Testosterone reproduction hormone level assay by using blood tissue allows us to define hatchlings sex without harming
them. Initially, it has to be confirmed that the sampled blood volume did not exceed 1 of the body weight Phillippa, 2011, personal communication.
