Chennai is one of the immense habitats of shrimps on the Indian coast and it offers heaps of commercial trading each year. Studies confessed that marine shrimp species have morphologically been delineated. Molecular identification is emerging as an essential vital supportive method for taxonomy-based species identification. In this study, we have provoked molecular data of taxonomically identified marine shrimp from the Chennai coast. All the sequences generated sequences showed 99–100% similarities with the referral database sequences (National Center for Biotechnology Information, GenBank). Sequence analysis of Cytochrome c Oxidase I gene conceivably directed that all the nine shrimp species parted into five distinct groups, which are genetically diverse from each other and exhibited identical phylogenetic reservation to their respective genus. Highest sequence divergence (0.332) have appeared between Heterocarpus gibbosus and Metapenaeopsis mogiensis and the lowest divergence (0.002) between Aristeus alcocki and A. virilis. Intraspecific variation ranged from 0.022 to 0.047 for A. alcocki and Solenocera crassicornis. Interspecific variation extended from 0.003 between M. stridulans and M. barbata to 0.332 between H. gibbosus to M. mogiensis. Thus, pervasive survey and more of molecular data of shrimps might actuate the ambiguous genetic variations and distances between and within the species.

Vermifiltration of wastewater using waste eater earthworms is a newly conceived novel technology. The present study evaluated BOD, COD and TS showing significant variation in decrease by 95%, 90% and 80% respectively through vermifiltration of distillery effluents. The nutrient contents (TN, TP, TK, TCa and TMg) in the vermicasts had increase (1.82 % in TN, 0.24% in TP, 2.15% in TK, 2.07% in TCa and 2.86 % in TMg) in the range of fold than the control level. The morphology of the control and experimental vermicast samples were analyzed with SEM and the image showed significant variation. The FT-IR spectrum analysis showed reduction of aliphatic/aromatic (C=C and OH) compounds in the vermicompost. Thus, the present study significantly highlights the vermifiltration technology in treating distillery effluent.
