| Summary: | A study was conducted at west part of Sarawak waters in Borneo, Malaysia to compare the
morphometric allometry of coastal horseshoe crab, Tachypleus gigas obtained from two different
locations, Pasir Putih Village and Gerigat Beach. The specimens were collected by using hand manually
and monofilament gill netting during March 2014 to April 2014. All measurements of body parameters of
male and female T. gigas from Gerigat Beach were recorded higher compared to specimens from Pasir
Putih Village. All body parameters between male and female T. gigas from both locations showed
significant different when p < 0.05. Allometric analysis was used to compare BW-TL/CW of T. gigas in log
transform by using Pearson correlation and regression analysis. Male and female T. gigas from both
locations revealed negative allometric growth for all body parameter relationships since ‘b’ value was less
than 3 excluding BW-CW and TEL-TL of female from Gerigat Beach. Two way ANCOVA analysis indicated
significant differences in BW-CW and BL-TL relationships of both sexes from two locations. The dissimilar
size of T. gigas from different locations in west Sarawak waters is probably due to two discrete
populations |
