“…The bacterial community analysis showed that Proteobacteria, Bacteroidetes, Firmicutes and Actinobacteria dominated the bacterioplankton during all sampling period. With exception of Firmicutes, the dominance of these groups is in agreement with our previous study on the dynamics of the bacterioplankton in this same aquaculture farm in a different year (2012) (Martins et al 2018). Furthermore, although there were some differences between the years (2012 and 2014), the main groups showed similar changes in their relative abundance in response to seasonal variation.…”

“…Recently, we have shown that microeukaryotic plankton communities in turbot and sole recirculating aquaculture systems (RAS) were dominated by bacterial grazers and represented by a large fraction of unknown organisms whose taxonomy and function have yet to be determined (Boaventura et al 2018). Our findings highlighted that the ecology of micro-eukaryotes in aquaculture systems are poorly understood, limiting our ability to understand their role in these systems.…”

“…Furthermore, the characterization of the whole genome of core dominant taxa growing across different systems could potentially reveal the true total genetic diversity these taxa may actually contain, through datadriven discoveries. 118 Currently there is also a huge knowledge gap regarding the protist community composition and its trophic interaction with the bacterial community within RAS and aquaponic systems, as barely a couple of studies have even looked into microeukaryotic diversity in RAS, 90,119 and only a handful of studies have looked specifically into the prokaryotic diversity of aquaponic systems. 7,10,120…”

Intensive aquaculture food production has been continually increasing over the past decades. Recirculating aquaculture is an innovative technology which relies on water reuse and removal of toxic metabolites by utilizing specific prokaryotic groups such as nitrifiers, settled in special biofilters. Focused on recent next generation sequencing-based studies on the microbiome of recirculating aquaculture systems, this review highlights dominant genera and families, and investigates their possible metabolic function in key niches within recirculating aquaculture systems (rearing water, biofilters and fish mucosal microbiome), while aiming to identify core prokaryotic groups across studies. A total of 136 genera belonging to 77 families and 13 phyla have been characterized as dominant or functionally important in relevant

“…The microbial community is a key player in the nutrient cycle process and maintenance, as well as the fish health in the aquaculture system. The composition and function of eukaryote microbes in the aquaculture system is still much unknown (Boaventura et al, 2018). Therefore, microbial abundance can be used as an ecological approach in the sustainable development of sustainable swamp aquaculture.…”

ABSTRACT Eucaryote microbes have an important role in forming bioflocs in the brackishwater aquaculture ponds. Bioflocs become potential live feed for milkfish or crustacea. This study aimed to identify the potential of eukaryotic microbes in the brackishwater aquaculture as the biofloc candidates potential development. This study was done through the water quality assessment and potential indigenous microbes isolation approach. Sampling was retrieved from the water subcomposite and sediment on each intertidal inlet and outlet. The water quality of brackishwater pond and intertidal swamp tended to lack of nutrient as containing inoptimal dissolved oxygen, salinity, pH, and ammonia content for the milkfish culture. Therefore, liming and fertilizing should be done to enrich the indigenous microbes. Eucaryote microbe isolated from the enrichment media was the aquatic fungi (multicellular and unicellular fungi) and microalgae (bacillariophyta, chlorophyta, and cyanophyta). Fungi and yeast formed a floculation with microalgae. This form will become a biofloc candidate as a live feed and water quality controller for the development of brackishwater aquaculture in the swamp area. Keywords: eucaryote microbes, biofloc, aquaculture, pond, brackish water swamp ABSTRAK Mikrob eukariot berperan penting dalam pembentukan bioflok di tambak budidaya pada lahan rawa payau. Bioflok menjadi pakan alami untuk budidaya ikan bandeng atau udang. Tujuan riset ini adalah mengidentifikasi mikrob eukariot rawa payau potensial untuk pengembangan kandidat bioflok di akuakultur rawa payau. Riset ini dilakukan dengan pendekatan kualitas air serta isolasi mikrob indigenous tambak dan rawa pasang surut untuk mendapatkan isolat mikrob potensial sebagai kandidat pembentuk bioflok. Sampling dilakukan secara subkomposit pada air dan sedimen di setiap inlet dan outlet pasang surut. Kualitas air tambak dan rawa pasang surut menunjukkan kondisi oksigen terlarut, salinitas, pH, dan amonia berada di luar batas optimum budidaya ikan bandeng, sehingga perlu dilakukan pengapuran dan pemupukan untuk memperbanyak mikrob indigenous-nya. Isolasi mikrob eukariot dari media pengayaan diperoleh jenis fungi akuatik yang multiseluler dan uniseluler, sedangkan mikroalga yang diperoleh yaitu dari golongan Bacillariophyta, Chlorophyta, dan Cyanophyta. Fungi yang dapat membentuk hifa dapat merangkai mikroalga dan khamir untuk membentuk flok. Susunan ini diharapkan dapat menjadi bahan bioflok yang berguna sebagai pengendali kualitas air sekaligus pakan alami bagi pengembangan budidaya di lahan rawa payau. Kata kunci: mikrob eukariot, bioflok, budidaya, tambak, rawa payau
