Abstract

This study was carried out to assess the toxicity and to identify the correlation between morphometric characteristic with the level of toxicity of the horseshoe crabs collected from Maludam, Sarawak. For morphometric study, only carapace width and weight of the horseshoe crab were measured. Based on the characteristic analyses, two species of horseshoe crab are identified which were Carcinoscorpius rotundicauda and Tachypleus gigas. Carapace sizes of C. rotundicauda are smaller compare to T. gigas. For toxin analyses, High Performance Liquid Chromatography (HPLC) method was used. Result obtained showed that both species of horseshoe crab found at Maludam were toxic but still considered safe for human consumptions. C. rotundicauda toxicity level score between 0.90 MU/g to 4.67 MU/g. Meanwhile for T. gigas toxicity level score range from 0.49 MU/g - 3.01 MU/g. For correlation study, SPSS software was used. According to correlation result, Pearson Correlation Coefficient (p<0.05) for C. rotundicauda was 0.283 and for T.gigas was 0.021. This result showed that morphometric measurement has weak correlation with level of toxicity in horseshoe crab. Meaning that morphometric characteristic does not influent the toxicity level in horseshoe crab. Present study is the first attempt to identify the relationship between morphometric characteristic with level of toxicity.
