Abstract
The research work was carried out to assess the dietary qualities of spiny lobsters collected from Visakhapatnam fishing harbour, situated on the northeast coast of Andhra Pradesh. The species selected were Panulirus homarus (Linnaeus, 1758), P. ornatus (Fabricius, 1798), P. versicolor (Latreille, 1804), and P. polyphagus (Herbst, 1793). The species were morphometrically measured, and their tissue was analyzed for the comparative proximate composition (Moisture, Protein, Lipid, and Ash) on a dry weight basis. Protein content was found to be high in all the lobster species. Highest protein content was observed in P. homarus (mg/g), followed by P. ornatus and P. versicolor (mg/g). Moisture percentage was 72.7, 75.7, 76.2, and 74.8% respectively. In addition, four minerals were analysed (Ca, Na, K, and Mg) in the present study. Calcium was observed maximum in all the species, and Magnesium was recorded minimum in all the lobsters.
