“…This was even more apparent in P. semilunaris , for which significant seasonal and intraspecific (i.e., male–female and juvenile–adult) differences were found in the present study, although the main preferred food item was by far represented by zooplankton (Rotifera), hence similar to other studies (Charlebois et al, ; Ghedotti, Smihula, & Smith, ; French & Jude, ; Adámek et al, , ; Kocovsky et al, ; Vašek et al, ; Všeticková et al, ). Indeed, Rotifera represented the majority of available prey in all seasons from the lakes investigated in the present study (e.g., Apaydın Yağcı & Ustaoğlu, ; Çelik & Giritlioğlu, ; Ergönül, Erdoğan, Altındağ, & Atasağun, ), and zooplankton was the most important prey group in the fish diet from İznik, Sapanca, Manyas, and Uluabat lakes (Okgerman et al, ; Stergiou et al, ). Stable isotope analysis of both species from the same lakes supports the present gut content analysis results (Tarkan et al, ), even though the dominant food groups were represented differently, for example, more abundant macrobenthos for both species in Lake İznik and Lake Sapanca, which are known for their rich macrobenthic fauna (Koşal Şahin & Yıldırım, ; Özbek et al, ).…”

The feeding ecology of the two gobiid species monkey goby Neogobius fluviatilis and western tubenose goby Proterorhinus semilunaris was studied in four natural lakes of the Marmara Region (NW Turkey), with special emphasis on seasonal and ontogenetic shifts in diet. Both species had similar food composition consisting of zooplankton and detritus. However, diet composition of both species significantly varied amongst lakes, and particularly so for P. semilunaris with seasonal and ontogenetic differences. Diet composition and seasonal/ontogenetic differences were overall similar to other populations of these gobiid species from both their native and nonnative ranges. The present findings suggest high plasticity in the diet of these two gobies, which can opportunistically utilize available food resources.

“…pH levels were in the alkaline range for both of them and electrical conductivity levels were 326 µS cm -1 and 594 µS cm -1 for the Kızıldamalar and the Boğazköy Reservoirs respectively. The total phosphorous concentration was reported as 54 µg L -1 for both reservoirs (Ergönül et al, 2016). It was concluded that the reservoirs showed eutrophic characteristics (Ergönül et al, 2016).…”

“…Due to these specifications K. cochlearis and P. vulgaris were found in almost all of the reservoirs in the Marmara Region. Also, these species were found in many reservoirs from different geographical regions and lakes in Turkey (Kaya and Altındağ, 2007;Ustaoğlu et al, 2012;Apaydın Yağcı, 2014;Saler and Alış, 2014;Apaydın Yağcı et al, 2015;Ergönül et al, 2016;Dorak et al, 2017;Dorak, 2019;Dorak et al, 2019).…”

In this study, the abundance of rotifera fauna, in the Büyükçekmece Reservoir (İstanbul) and some physicochemical features of the reservoir, were investigated between May 2009 and February 2010. In terms of physicochemical conditions, the trophic state of the reservoir was determined as eutrophic (CTSI= 57.8). A total of 33 rotifera species were identified. Keratella cochlearis represented 40.62% of the total annual rotifera present, and was predominant. It was followed by Polyarthra vulgaris (10.14%), Synchaeta oblonga (9.06%), Brachionus urceolaris (5.58%), Pompholyx sulcata (5.21%) and Epiphanes macroura (%4.86), respectively. The contribution of the other rotifer species to the annual presence of rotifera was determined as being 24.52%. The dominance of these species was attributed to the eutrophic state of the reservoir, because K. cochlearis, P. vulgaris, B. urceolaris and P. sulcata are known as eutrophication indicator species, due to their saprobic valences. Also, the trophic state of the reservoir was found to be eutrophic according to the Q B/T index (= 3). According to the present data about rotifera species, and the abundance of them, the Büyükçekmece Reservoir was specified as eutrophic. However it is necessary to follow the conditions with periodic monitoring to observe the alterations in the Büyükçekmece Reservoir, in this respect the results of the present study would constitute an important baseline for subsequent studies.

“…They could be non-motile or very poor swimmers; drifting in the water column of water bodies and depends on water to get to any great distance (Ferdous & Muktadir, 2009). They are closely linked to the environment, quickly responding to changes and their distribution is strongly influenced by environmental parameters (Roman et al, 2012;Vincent et al, 2012;Lin et al, 2014;Ergönül et al, 2016). Zooplanktons have been reported to be good bioindicators of water quality (Ferdous & Muktadir, 2009;Davis & Ugwumba, 2013;Dorak, 2013;Kutama et al, 2014 andJob et al, 2017).…”

Spatio-Temporal Assessment of Zooplankton Fauna of Uta Ewa Estuary, Akwa Ibom State, Nigeria.

Estuaries are influenced by the mixture of river water with seawater; creating unique ecosystems with several physical and chemical processes affecting the water quality. Spatial and temporal assessment of the composition, abundance, and distribution of zooplankton fauna of Uta Ewa Estuarine water system was carried out between May 2019 and February 2020 to assess the effects of anthropogenic activities on the zooplankton assemblage. Water and Zooplankton samples were collected from three (3) stations using standard procedures. Some parameters like water temperature, dissolved oxygen, hydrogen-ion, electrical conductivity, and turbidity were determined in-situ. The ranges of the physico-chemical parameters were: water temperature (24.9-25.3oC), EC (62.3-70.9mS/m), pH (6.5-6.7), turbidity (12.0-28.0NTU), DO (3.8-4.7mg/L), BOD (2.3-3.2mg/L), phosphate (3.2-5.2mg/L), and nitrate (3.0-6.3mg/L). ANOVA showed a significant difference (p<0.05) in the spatial and temporal means values of some parameters. A total of 1,067 individuals from 30 zooplankton taxa and 4 taxonomic groups were recorded. Rotifers (33.4%) were the dominant group, followed by protozoa (32.9%), copepods (20.9%) and cladocerans (13.8%). Station 1 had the highest abundance (388 individuals), station 2 (303 individuals) and station 3(375 individuals). The higher number of individuals (193) was recorded in August 2019. The biodiversity indices pointed to slightly polluted to stable environment. This study showed that the water quality and zooplankton community was influenced by anthropogenic activities both spatially and temporally but season also played a major role in the temporal variation. In conclusion, the water quality was deteriorating due to anthropogenic activities, which in turn affected the structure of zooplankton community.
