Biochemical Composition in Two Populations of the Mantis Shrimp, Harpiosquilla raphidea (Fabricius 1798) (Stomatopoda, Crustacea)

The mantis shrimp, Harpiosquilla raphidea, is a valued crustacean species captured mainly in some Indonesian coastal waters. Yet, the biochemical composition of this species is still inadequately understood. For that reason, the aim of this study was to quantify the content of essential elements of specimens from the Kuala Tungkal, Jambi and Cirebon Coast. The meat yield of the shrimps collected from the two locations are not significantly different. In terms of proximate chemical composition, all chemical characters of the shrimps from Kuala Tungkal, Jambi and Cirebon are not significantly different, except the fat content. As far as the mineral composition is concerned, no differences were observed between either two locations for micro minerals (zinc, iron and copper). However, the shrimps of Kuala Tungkal, Jambi coast showed higher sodium, potassium and calcium contents than those of Cirebon coast. Yet, for magnesium the shrimp of Cirebon had higher content in comparison with that of Kuala Tungkal, Jambi. Media acid with boiling process would bring about the highest solubility of minerals.
