“…Among them, Sagitta enflata (1441 individuals/m³) was the dominant species followed by S. bedotii (624 individuals/m³) and S. robusta (186 individuals/m³). It is a temperate and warm water species (Muthukumaravel, 2021). Hence, they are found in abundance in the present study period, according to B.K Sahu (2013) (Velmurgan, P., 2014), S. enflata was more abundant in coastal regions.…”

The present study was done to understand the abundance and species diversity of arrow worms, zooplankton in relation with hydrographical parameters and the spatial and temporal variations for a period of 16 months from October 2020 to March 2022. Monthly sampling was carried out at selected stations of coastal waters with average depth of 8m. The qualitative analyses revealed the presence of seventeen different groups of zooplankton. copepods, cladocerans are dominant group in zooplankton followed by chaetognaths, during the study period seven species of chaetognaths recorded viz, Sagitta enflata, Sagitta robusta, Sagitta bedotii, Sagitta bipunctata, Sagitta ferox, Sagitta planktonis, and Sagitta elegans. Among them, Sagitta enflata was the dominant species followed by S.bedotii and S. robusta. The richness, evenness and diversity of chaetognaths varied in the different stations and the maximum and minimum values also varied between stations, but in the most of the stations the minimum values were observed in the post-monsoon season and the highest values ranged between January to March. On comparison of the present abundance of chaetognaths with previous study, it was observed that the density of chaetognaths decreased compared to previous studies.

“…In the sampling site, the percentage wise catches of fishes was order Perciformes (71.75%) followed by Siluriformes (9.6%), Gonorphynchiformes (8.9%), Clupeiformes (8.13%) and Beloniformes (1.55%). Among the 19 species recorded in the present study, Mugil cephaluswas dominant species contributed about 12.01% whereas Liza parsia accounted for about 9.68% as the second dominant species" [32]. The third dominanat species was Chanoschanos with a contribution of 8.91% followed by Leiognathusequulus (8.52%).…”

The seasonal variations of physico-chemical parameters on fish faunal diversity were studied in Muthukuda mangrove (Latitude 9o36’N and Longitude 78o83’E) waters from July 2022 to June 2023. The atmospheric temperature and water temperature ranged from 27.7 to 34.9°C and 25.8°C to 30.9°C respectively. The Hydrogen ion concentration of water varied from 7.3 to 8.3. The dissolved oxygen was ranged from 7.3 to 8.3. Salinity fluctuated between 10.5 to 31.9‰. The nutrients such as total phosphorus, nitrate and silicate ranged from 0.7 to 3.2 µg/l, 5.1 to 13.7 µg/l and 9.2 to 71.2 µg/l respectively. The dissolved oxygen and nutrients were found to be low in summer and high during the monsoon season. Similarly, temperature, pH and salinity were low during the monsoon season and high during the summer season. Fish faunal diversity from Muthukuda mangroves comprises 19 species representing 5 orders, 17 families and 19 genera. The order Perciformes were dominated by 13 species followed by Clupeiformes and Siluriformes 02, Gonorphynchiformes and Beloniformes with one species each. The higher diversity values in fish fauna observed in the present investigations clearly elucidated the healthy nature of Muthukuda mangroves.

Monthly sampling was carried out at selected stations of coastal waters with average depth of 8m. The qualitative analyses revealed the presence of seventeen different groups of zooplankton. copepods, cladocerans are dominant group in zooplankton followed by chaetognaths, during the study period seven species of chaetognaths recorded viz,Sagitta enflata, Sagitta robusta, Sagitta bedotii, Sagitta bipunctata, Sagitta ferox, Sagitta planktonis, andSagitta elegans. Among them,Sagitta enflatawas the dominant species followed byS.bedotiiandS. robusta. The richness, evenness and diversity of chaetognaths varied in the different stations and the maximum and minimum values also varied between stations, but in the most of the stations the minimum values were observed in the post-monsoon season and the highest values ranged between January to March.
