“…Hydrobiology of water viz., temperature, salinity, pH and nutrients influences distribution of zooplanktons and causes seasonal changes in community structure (Thirunavukkarasu et al, 2020) which is evidenced in the present study at Ennore Mangrove ecosystem. The study area showed significant variation in the hydrobiological parameters, population density, species composition, species diversity, species evenness and species richness of zooplankton community across the four stations in the study.…”

Hydrobiology regulates the plankton diversity in a water body and is a fundamental research area in aquatic and ecological studies. The present study was carried out to assess the zooplankton diversity and physicochemical parameters viz. temperature, salinity, pH, phosphate and nitrite by collecting water samples at four stations in Ennore estuary for the period of one year from January to December 2021. Investigation of species diversity, composition, richness and evenness predicted that the diversity status of zooplanktons is influenced by the hydrobiology of Ennore backwaters.

“…Among these are heavy metals (aluminum, zinc, lead, selenium, chromium, nickel and cadmium etc. ), nicotine, ethyl phenol, ammonia, formaldehyde, butane, acrylonitrile, toluene, benzene, alkaloid, cyanide, and asbestos most of which have a genotoxic effect (Al-Saleh et al, 2020 ; Gökalp et al, 2020 ; Laio et al, 2019 ; Salem et al, 2018 ; Thirunavukkarasu et al, 2020 ; Yamin et al, 2020 ; Zafra-Lemos et al, 2021 ; Zhang et al, 2020 ). The origin of the majority of these chemical compounds in cigarettes come from pesticides, insecticides, herbicides, and fungicides used in tobacco culture (Lee, 2012 ), which also present genotoxic potential (Amaeze et al, 2020 ; Oliveira et al, 2020 ).…”

Tourist occupancy in coastal environments threatens the stability of various coastal ecosystems and is thus a cause for concern for the environmental sector. As such, it is important to perform environmental monitoring in a way that analyses and quantifies the environmental impact of coastal ecosystems. Porto de Galinhas beach (Pernambuco – Brazil) has one of the highest visitation rates in Brazil and suffered from restrictions to human mobility due to the COVID-19 pandemic. These restrictions allowed for the evaluation of the impact of tourism on Porto de Galinhas beach and the effects that the lack of tourist occupancy had during the lockdown period of 2020. Blood samples from the species Abudefduf saxatilis were collected monthly over a period of 1 year and during the lockdown quarter, in order to perform micronucleus (MN) and nuclear morphological alteration (NMA) tests, and data were analyzed at a seasonal level (dry/rainy period) using a comet assay. For the control group, A. saxatilis samples were collected in an environmentally protected area on Tamandaré beach (68 km from Porto de Galinhas). The MN and NMA tests showed a greater frequency of genomic damage when there was greater tourist flow. In relation to rain seasonality, the comet assay showed a greater incidence of genomic damage during the dry period, where there was a higher rate of tourist migration, compared to the rainy period. The lockdown period presented a lower incidence of genotoxic damage compared to the period without restrictions on human mobility and the control. The results show that tourism has been causing a significant environmental impact on Porto de Galinhas beach. The data collected during the lockdown period demonstrated how the absence of human movement results in changes that are favorable to environmental recuperation, as illustrated by the lower frequency of genomic damage.

“…The increase in the plankton population is generally caused by a high concentration of nutrient load in the study area. [7]. The results of the study on the Mediterranean coast have a potential diversity in assessing regional influences and producing plankton diversity as an ecological indicator; plankton diversity can be used for significant environmental assessment [8] [9].…”

“…Hatchery and aquaculture activities can cause affect the quality of the coastal environment, including physical, chemical conditions and the abundance of plankton in the waters. The concentration of nutrients will affect the aquatic plankton community [7] [8]. Plankton community significantly correlates with water ecological conditions; especially nitrite, salinity, transparency, TDS, TSS, and pH [9].…”

The northwest coastal area of Bali is currently for the development of marine fish hatcheries and cage farming. This study aims to influence the hatchery and aquaculture activities of marine fish cages in the northwest coastal area of Bali on seawater quality and plankton community. The parameters observed on water quality were total suspended solids, temperature, transparency, pH, dissolved oxygen, Salinity, ammonia, nitrite, nitrate, phosphate, C-organic, total organic matter, and plankton community on diversity, similarity, and dominancy index. The results of water quality observations found that water temperature was 27.5-29.1°C, TSS 0.028-0.046 ppm, transparency 7.4-12.8 m, pH 8.1-8.3, DO 5.4-6.9, Salinity 33.2-34.1, ammonia, 0.01-0.04 ppm, nitrite 0.028-0.041 ppm, nitrate 0.018-0.036 ppm phosphate 0.026-0.038 ppm, C-Organic 0.65-0.74 ppm, TOM 0.75-1.23 ppm. Found 38 genera and 10 phyla of plankton, with an abundance was 258-26,546 ind/L, an index of the diversity of 0.89-2.15, an index of similarity of 0.22-0.64, and an index of dominancy 0.18-0.43. From these results, it can be concluded that the coastal waters of northwest Bali are in the criteria that have not been polluted and are good for marine fish farming. The northwest coastal area of Bali must be managed properly so that marine fish farming can be sustainable.
