“…Similar readings were observed by Gupta et al . (1988), Shwetha (2010), Shruthi (2015) and Karati, K.K., 2021, who observed higher abundance in post-monsoon and pre-monsoon season. The maximum (0.99) richness was observed November at station 2 (coastal waters off Thannirbhavi) and minimum (0) was observed in the month of October in all the stations except at station S4.…”

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, 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. On comparison of the present abundance of chaetognaths with previous study, it was observed that the density of chaetognaths decreased compared to previous studies.

“…According to Mohanty et al (2007). During this period, river influx was much less, as evident from salinity distribution, restricting the advection of the bloom offshore [21][22][23][24][25][26][27][28][29][30].…”

The phytoplankton distribution and biochemical composition concerning water quality parameters were studied in the coastal waters off Mangalore, Monthly sampling was carried out from October 2020 to May 2022 at selected stations of Netravathi-Gurupura estuary, latitude 12°50'38.56" N, longitude 74°50'0.23° to coastal waters off Padubidri latitude 13° 8'0. 57" N longitude 74°42'9.47° with an average depth of 8 meters. Spatiotemporally the phytoplankton, chlorophyll-a and phytoplankton biochemical composition showed a significant difference for the entire duration. During the present investigation, 35 different phytoplankton genera belonging to 3 groups were observed with complete domination from diatoms with 27 genera followed by Dinoflagellates 7 and blue-green algae. distribution and abundance of the phytoplankton were mainly Chaetoceros sp., Ceratium sp., Thallasiocera sp., Biddulphia sp., Coscinodiscus sp., Rhizosolenia sp., Ditylum sp., Triceratium sp., Nitzschia sp. and blue-green algae under Chrysophyta, Bryophyta, Chlorophyta, Cyanophyta were observed, while in biochemical composition of phytoplankton, the carbon contributed to the highest percentage and hydrogen constitute to the lowest percentage. Crude protein and Lipid contents are maximum during post-monsoon and carbohydrates showed their highest content during pre-monsoon for phytoplankton. There is a direct relationship between the biochemical composition and the physiochemical and environmental conditions including nutrients, especially nitrates and phosphates.
