Abstract
The assessment of species diversity in a particular region is very important in formulating conservation strategies. In the present study, the diversity of marine shrimp species along the coast of Nagapattinam,Tamil Nadu has been assessed on the basis of landing of variety of shrimp species. Penaeidae species were recorded from four landing sitesviz.Akkaraipettai (Station1), Keechankuppam (Station 2), Samandanpettai (Station 3) and Nagore (Station 4) for the period of three months (Dec’2016- Feb’17). Totally 10 shrimp species viz., Penaeus monodon, Penaeus indicus, Penaeus semisulcatus, Penaeus merguiensis, Penaeus (Litopenaeus) vannamei, Penaeus affinis, Metapenaeus dobsonii, Metapenaeus monoceros, Metapenaeus brevicornis and Parapenaeopsis stylifera belonging to family Penaeidae were identified. All the species were available in all four stations during the study period except Penaeus (Litopenaeus) vannamei, Metapenaeus monoceros and parapenaeopsis stylifera were not found regularly. The occurrence of different species in different stations were presented in the following order: Akkaraipetai > Keechankuppam > Samandanpettai and > Nagore. The maximum and minimum number of shrimp species (6 and 4 species) recorded in all the months. Parapenaeopsis stylifera was minimum catch in all the months. December 2016 was ideal month for the maximum shrimps catches. Shrimp diversity is good in Nagapattinam and abundance of shrimp species are greatly influenced by environmental changes and destructive human activities.
