“…Although traditional aquaculture made a great contribution to the supply of aquatic products, problems associated with environmental protection and food safety seriously limited its sustainable development in the future. Problems commonly occurred in the traditional aquaculture industry include water deterioration and antibiotics abuse [9].…”

“…Water deterioration, which refers to oxygen depletion, harmful algal bloom, and eutrophication of water body in aquaculture, may lead to the failure of aquatic animals rearing and even cause serious environmental disasters [9,22,23]. As shown in Figure 1, the water deterioration mainly occurs in three aspects: (1) The addition of an excessive amount of traditional aquaculture feed, which consists of biomass rich in protein and lipid, may not be fully eaten by aquatic animals and the residual feed would be converted to soluble nutrients, driven by some bacterial activities, partly contributing to the eutrophication in water body.…”

“…In the study of Mirzoyan et al (2008), aquaculture sludge was subjected to anaerobic treatment for methane production and up to 70% sludge-mass reduction was demonstrated [28]. However, from the perspective of nutrients recovery, these traditional treatment technologies are not highly recommended [9]. For example, organic carbon in aquaculture wastewater is converted to CO 2 and CH 4 by aerobic and anaerobic treatment.…”

“…By traditional technologies, nutrients, including nitrogen, phosphorus, and carbon, in wastewater could not be fully utilized and recycled as resources. Some technologies may produce a large amount of carbon dioxide and sludge, causing secondary environmental pollution [9]. In aquaculture, antibiotics and medicine are commonly used as a feasible way to prevent animals' diseases and reduce aquaculture risks.…”

Traditional aquaculture provides food for humans, but produces a large amount of wastewater, threatening global sustainability. The antibiotics abuse and the water replacement or treatment causes safety problems and increases the aquaculture cost. To overcome environmental and economic problems in the aquaculture industry, a lot of efforts have been devoted into the application of microalgae for wastewater remediation, biomass production, and water quality control. In this review, the systematic description of the technologies required for microalgae-assisted aquaculture and the recent progress were discussed. It deeply reviews the problems caused by the discharge of aquaculture wastewater and introduces the principles of microalgae-assisted aquaculture. Some interesting aspects, including nutrients assimilation mechanisms, algae cultivation systems (raceway pond and revolving algal biofilm), wastewater pretreatment, algal-bacterial cooperation, harvesting technologies (fungi-assisted harvesting and flotation), selection of algal species, and exploitation of value-added microalgae as aquaculture feed, were reviewed in this work. In view of the limitations of recent studies, to further reduce the negative effects of aquaculture wastewater on global sustainability, the future directions of microalgae-assisted aquaculture for industrial applications were suggested.

Aquaponics is considered as a possible method to produce aquatic animals and plants in an environmentally-friendly way, but its commercialization is seriously hindered owing to some technical and economic problems. Recently, the integration of microbial community with aquaponics is on the way to becoming the next-generation technology for the sustainable development and commercialization of the aquaponics industry. This article provides an authoritative discussion on the novel microbial community-assisted aquaponics, which will be emerging from the research environment to industrial application in the coming future. Principles and key technologies of this novel aquaponics, as well as the potential challenges to its commercialization, are discussed. It is expected that the emerging technologies discussed in this work could address the existed technical problems and further promote the commercialization of aquaponics.

The application of microalgae biotechnology, which can recover nutrients from wastewater, improve water quality, and feed some aquatic animals, is becoming an emerging trend in the development of eco-friendly aquaculture. Previous studies explored a variety of models to support the use of microalgae in aquaculture practice, verifying the feasibility and advantages of microalgae-based aquaculture. However, a couple of bottlenecks and problems jeopardizing the application of microalgae biotechnology in aquaculture are discovered in the research and industrial practice. This work, hence, summarizes the research progress and the current opinions relating with the microalgae-based aquaculture and proposes some critical thoughts about the bottlenecks challenging its industrial implementation.
