“…may attract insects, reduce water quality and when decomposing can deplete oxygen. However, an experiment by Addy et al (2017) shows that algae can improve water quality in an aquaponic system, help control pH drops related to the nitrification process, generate dissolved oxygen in the system, 'produce polyunsaturated fatty acids as a value-added fish feed and add diversity and improve resilience to the system'. One of the 'holy grails' of aquaponics is to produce at least part of the food that is fed to the fish as part of the system and it is here that research is required in producing algae that could be grown with part of the aquaponics water, most probably in a separate loop, which can then be fed as part of the diet to the fish.…”

Whilst aquaponics may be considered in the mid-stage of development, there are a number of allied, novel methods of food production that are aligning alongside aquaponics and also which can be merged with aquaponics to deliver food efficiently and productively. These technologies include algaeponics, aeroponics, aeroaquaponics, maraponics, haloponics, biofloc technology and vertical aquaponics. Although some of these systems have undergone many years of trials and research, in most cases, much more scientific research is required to understand intrinsic processes within the systems, efficiency, design aspects, etc., apart from the capacity, capabilities and benefits of conjoining these systems with aquaponics.

The paper main objectives are to identify an analysis model for development of integrated aquaponics with intensive beekeeping. The socioeconomic environmental impact assessment provides the opportunity to analyze the determinants of public attitude towards the use of multifunctional aquapson. In relation to the other agricultural production branches, beekeeping integrated into aquaponic systems is an environmentally friendly technology that does not use additional energy supply within the integrated production system and also recycles waste water from aquaculture through mechanical, biological filters and plant roots.

“…The rationale for the utilization of aquaculture sludge as a fertilizer for direct land application [45] or for compost production [67] is that its concentrations of toxic and other health-threatening constituents are low in relation to those evident in domestic-and industry-origin sludge, even though it is treated with domestic and industrial wastes (along with other livestock waste) in centralized facilities entailing the same primary, secondary and tertiary treatment steps [71]. Recent studies have shown that plant growth and germination were improved when microalgae biomass was added to fertilizer or media for plant cultivation [72][73][74]. Additionally, aquaculture wastewater is itself used directly for plant growth [75][76][77], since it contains dissolved rich nutrients (feed residue, gill excretion, feces and urine) that are composed of both soluble and solid organic compounds solubilizable to the ionic form in water and assimilable by plants [78].…”

“…Therefore, it is expected that the ABFT system's microalgal-biomasscontaining sludge can be indirectly utilized as natural fertilizer, and that its wastewater can be directly used for plant cultivation (Figure 3). Another advantage of the ABFT system is that it can have a positive effect on production economics by simplifying the production process steps so that fish breeding and wastewater treatment are performed simultaneously, rather than independently as in existing onshore systems such as biofloc technology (BFT) [79], recirculating aquaculture systems (RAS) [80], and aquaponics [73]. The ABFT system can also help to solve the problem of global climate change by atmospheric carbon dioxide emissions, because autotrophs such as microalgae convert carbon dioxide to carbohydrates through photosynthesis.…”

Utilization of Microalgae in Aquaculture System: Biological Wastewater Treatment

We recently developed an autotrophic biofloc technology (ABFT) system entailing simultaneous microalgae co-culturing with juvenile-farming-stage fish and shrimp in aquaculture and microalgae-based water treatment. The present study was conducted to confirm the potentialities of the ABFT system at the remaining stages (seedling to adult farming, Nile tilapia) for industrial-level implementation. In the results at the seedling stage, an excellent water-purification effect and significant water conservation (97% reduction) by microalgae were verified. Indeed, among the fish, there were not any significant differences, either in growth performance or in body composition, and the wastewater from this system was recycled by use for the growth of various plants. Further, the ABFT system was demonstrated to have a positive effect on production economics by simplifying the production process steps (simultaneous fish breeding and wastewater treatment) and providing for a natural hatching environment. In summary, the ABFT system can be integrated with existing systems on an industrial level as an effective and efficient means of achieving sustainable aquaculture.
