“…"Salinity is one of the most important hydro graphical parameters, which considerably influences almost all other physical and chemical properties of seawater and thus, significantly determines the distribution of biological communities" [26].The salinity was found to be high during summer (May) 2022 and low in monsoon (October) 2021 at both the stations. The recorded higher salinities could be attributed to the low amount of rainfall beside high temperature, higher rate of evaporation and also due to neritic water dominance.…”

Water quality parameters and plankton were analysed in two fishing harbors (Chinnamuttom and Colachel), waters along the complex aquatic ecosystem at Kanyakumari district during July 2021 - June 2022. Seasonal variations of physico-chemical parameters such as AT (27-34oC), SST (24.3-31oC), pH (7.46 -8.12), salinity (28.0-33.5 psu) ,DO (3.4-5.6 mg/l) and the inorganic nutrients such as NO3 (0.042-0.14 mg/l), NO2 (0.074-0.088 mg/l), PO4 (0.078-0.193 mg/l), SiO4 (0.480-0.797 mg/l) and NH3 (0.054-0.127 mg/l) were estimated in selected study site i.e. harbor waters. A total of 74 species of phytoplankton was recorded in Chinnamuttom harbor water and 59 species were recorded in Colachel harbor water during the study period. Bacilariophycea were dominantly recorded in both ststions.Totally 56 species of zooplankton were observed in Chinnamuttom harbor whereas 46 species were found in colachel harbour. Calanoid groups were dominantly recorded in both stations during the study period. Also the physicochemical parameters influence was correlated.Statistical tools PRIMER (Ver. 6.1.11) and Origin Pro 8.0. were employed to find the species diversity, richness and evenness were calculated.

“…The distribution of the zooplankton community depends on several factors, such as climatic conditions, water physical and chemical parameters, and biological interactions [67]. Zooplankton changes in response to changes in water quality and environmental parameters influencing the changes in zooplankton abundance [68].…”

Between 2013 and 2020, a total of 27 distinct zooplankton taxa, encompassing both holoplanktonic and meroplanktonic organisms spanning different classes and orders, were successfully identified along the Romanian Black Sea coastline. The seasonal dispersion patterns of these zooplankton taxa revealed a notable augmentation in species identification during the warmer periods, contrasting with reduced zooplankton diversity during the colder seasons. This phenomenon was underscored by the outcomes of SIMPER analysis, which highlighted that copepods, meroplankton, and cladocerans predominantly contributed to the community structure during warmer seasons. In contrast, during colder seasons, cladocerans were scarcely represented, and the density levels of copepods and meroplankton were diminished. From a quantitative perspective, the dinoflagellate Noctiluca scintillans, exhibited its highest density and biomass during the warm season, with a relatively lower representation during colder periods. The variation in the abundance of zooplankton was closely linked to changes in salinity and temperature, culminating in noticeable fluctuations, which were particularly evident during the cold season. During this period, the values of zooplankton abundance were notably lower compared to those observed in the warmer season. The comprehension of zooplankton dynamics stands as a critical facet for assessing biodiversity, monitoring ecosystem well-being, and guiding conservation endeavours.
