Abstract

Mohale, H.P.; Jawahar, P.; Jayakumar, N.; Oli, G. Arul; Ravikumar, T., and Bhosle, R., 2024. Ecomorphology of selected penaeid shrimp in the coastal marine waters of Tamil Nadu (southern India). Journal of Coastal Research, 40(2), 303–318. Charlotte (North Carolina), ISSN 0749-0208.

This study investigated how shrimp morphology is influenced by the environment by examining the effects of components like temperature, salinity, substrate type, and water currents; it exposed how these variables affect the development and expression of morphological traits in shrimp species by examining patterns of morphological variation within and between species to demonstrate the contributions of natural selection, genetic drift, and phenotypic plasticity to the diversification of shrimp morphology. The prevalence of shrimp species was: Penaeus indicus > Metapenaeus dobsoni > Metapenaeus brevicornis > Penaeus canaliculatus > Penaeus semisulcatus > Penaeus mergiuensis > Penaeus japonicas > Metapenaeus moyebi > Penaeus latisulcatus > Penaeus monodon. The study results showed negative correlations between biochemical oxygen demand and dissolved oxygen and a harmful effect on the morphological characteristics and growth of shrimp species. According to single factor and comprehensive pollution indices, the water bodies in this study were moderately polluted. P. semisulcatus had higher mean values for the ecomorphology parameters, indicating no adverse effects and a positive relationship. P. semisulcatus shrimp were also found to have decadal growth development and survivability. P. mergiuensis had the lowest growth rates. Results indicated detrimental effects and a bad association when evaluating decadal growth, development, and survival for most of the other shrimp species. This study enhances knowledge of the evolutionary processes that have shaped shrimp adaptations over time and highlights the challenges for sustainability of the biodiversity in the coastal marine waters of Tamil Nadu, India.
