“…This substitution may occur by rotifers or even small cladocerans, such as M. minuta, which increased at the end of the experiment. Furthermore, as reported by Vieira et al (2011), D. spinulosum grows better in nutrient-poor environments, which explains the negative correlation of this species with chlorophyll-a in the present experiment. Although there was no correlation between the physical and chemical variables and M. minuta, it had a marked increase in abundance at the end of the experiment.…”

Integrated multitrophic aquaculture (IMTA) is an alternative means to optimize feed usage in aquaculture which combines species of different trophic levels. The addition of substrate to IMTA has also been used to promote a lower release of phosphorus, thus minimizing eutrophication and impacts of effluents. In these aquaculture systems, the zooplankton community is important because it acts as a link in trophic chains. This study aimed to verify the dynamics and the structure of the zooplankton community in IMTA (tilapia-prawn), in response to trophic conditions in earthen ponds with different substrates. The object of the study was 12 earthen ponds organized in three treatments: no substrate (control), geotextile substrate, and bamboo substrate. Zooplankton samples were taken biweekly through a water bilge pump. Rotifers and microcrustaceans were identified and counted to determine changes in community diversity during the experiment. Eutrophication was determined throughphosphorus and chlorophyll water concentrations. There were no differences in zooplankton communities among treatments, even though increases in levels of eutrophication of the system heavily influenced this community, by altering its diversity and abundance. Small organisms were the most representative ones under polyculture eutrophic conditions.

“…Among the main groups of aquatic organisms, zooplankton stands out for being able to react quickly to environmental and toxicological changes (Moreira et al, 2014;Vieira et al, 2011). In this sense, the zooplankton can be used as variable for environmental monitoring because, in addition to responding human impacts, it plays an important role in nutrient cycling and energy flow of food webs (Gagneten & Paggi, 2009;Oberhaus et al, 2007;Vieira et al, 2011).…”

Abstract: Aim:In order to contribute to the knowledge about the simplification of biological surveys, this study evaluated the use of substitute groups, numeric and taxonomic resolution for the three main groups of zooplankton (cladocerans, copepods and rotifers) in a Hydropower Plant (UHE). The following issues were addressed: (i) the patterns of spatial and/or temporal ordering generated between each zooplankton group are in concordance? (ii) The concordance is maintained using presence/absence data instead of density data? (iii) The identification of organisms to the species level can be replaced by genus or family level? Methods: Samples were taken in seven sample units over five campaigns between 2009 and 2010 in the UHE Serra da Mesa (Goiás, Brazil). To evaluate the correlation between each pair of matrices was used the Mantel test. Results: The results demonstrate that the replacements should not be made among the zooplanktonic groups, requiring the monitoring of three groups (copepods, cladocerans and rotifers). Furthermore, the results suggest the use of density data of individuals rather than just presence/absence of species. Finally, the results of this study indicate the possibility to use data at species level instead of data at genus or family level. Conclusion: For zooplankton community monitoring purposes only the use of taxonomic resolution showed to be efficient for this area of study, not being recommended the use of surrogate groups or numerical resolution.

“…Salinity increase in freshwater has the potential to reduce zooplankton richness especially in the cladoceran community and thus, change adaptation of the species to a more salt tolerant species (Reliana, 2012). Research on cladocerans has been widely conducted, due to their ecological importance, sensitivity towards environmental changes and ease of handling (Sarma & Nandini, 2006;Ana Carolina et al, 2011). Cladocerans are an important group in the zooplankton community with most of the species living in freshwater environments with salinities of <1psu (Ghazy et al, 2009).…”

Salinity is a known factor which shapes population dynamics and community structure through direct and indirect effects towards aquatic ecosystems. The responses of Moina macrocopa (Cladocera) collected from Setiu Wetland lagoon (Terengganu) were evaluated through manipulative laboratory experiments to understand the ability of M. macrocopa to tolerate under high salinity stress. Specifically, the fatty acid composition, growth, survival and reproduction of this cladocerans species were examined. Sodium chloride (NaCl) were used in the treatments water with the concentration 0, 4, 6, 8, 12, and 15psu. Fatty acid levels were determined using Gas Chromatography and Mass Spectrophotometry (GC-MS). Results clearly indicate that normal conditions give the highest content of fatty acid, especially the polyunsaturated fatty acid content like EPA (eicosapentaenoic acid), ALA (alpha-linoleic acid), ARA (arachidonic acid) and DHA (docosahexaenoic acid). Furthermore, M. macrocopa survival also was best at 0psu, with percentage reached 98%, whereas the opposite occurred at 15psu, with approximately 9% of viable animals survived. On other aspects, M. macrocopa also showed the highest reproduction rate at 0psu (e.g. average initial age of reproduction, 4.33±0.58 days) compared with other salinities level. Interestingly, the difference in terms of growth at different salinities was unapparent, an unexpected outcome when adverse effects such as osmoregulation pressure on the organism are considered. Based on the results, we conclude that M. macrocopa can only tolerate salinity below 8psu and, is unable to withstand stressful environmental condition engendered with salinities above 8psu.
