    Abstract

    The findings of the present study, twenty-one deepsea caridean shrimp species were identified by conventional taxonomy during the study under seven families Pandalidae, Acanthephyridae, Oplophoridae, Crangonidae, Pasiphaeidae, Glyphocrangonidae, Hippolytidae and Stylodactylidae. Out of twenty one, thirteen species are new distributional records reported for the first time from the southern coast of India. The family with the highest number of species observed was Pandalidae (6), Crangonidae (4), Acanthephyridae (1), Pasiphaeidae (1) and Glyphocrangonidae (1). Accounting to molecular analysis a total of 121 sequences of COI and 16S was deposited in the GenBank database belonging to 8 genera under 5 families from the southern coast of Indian water. The truss morphometric analysis of H. chani confirms the presence of three distinct populations along the southern coasts of India. Based on reproductive biology of H. chani, A total of 1518 male individuals were measured from five landing centers along the southern coast of India ranging in total length from 7 to 13 cm, 1,206 non ovigerous females ranging from 6.4 to 14 cm and ovigerous females (633 specimens) ranging between 8.5 to 14 cm. The body weight in males ranged between 0.9 to 14.3 g, non ovigerous females 1.0 to 21.1 and ovigerous females are 3.4 to 26.6 g and fecundity estimation revealed the average absolute fecundity was 19041 eggs, which varied from 830 to 45650 in females (Stage 1) with the total length of 90 to 134 mm and carapace length in 20 to 36 mm of the specimen along the southern coast of India.
