“…By integrating microalgae into the recirculated aquaculture system (RAS), it can help to maximize the recycling process of nutrients where identified can remove NH 4 + -N up to 95.49% to 100% and also is efficient in removing phosphate, PO 4 3 higher than 80% (Duan et al, 2022). Microalgae such as Chlorella marina, Tetraselmis suecica and Picochlorum maculatum can help remediate the nutrients from aquaculture wastewater where these types of microalgae can remove maximum amount of NH 3 -N, NO 2 -N, total nitrogen (TN) and total phosphorus (TP) (Meril et al, 2022). The uptake of the nutrients from the wastewater of aquaculture system can be developed into microalgae biomass which can then be used as biofertilizer (Meril et al, 2022).…”

Towards the sustainable aquaculture production, more recent technologies have been developed in the past few years. The application of effectives microbes (EM) in controlling water quality, the application of biofloc technology, aquamimicry, Black Soldier fly (BSF) as supplemental protein feed, application of triploidy, polyploidy, vaccines, probiotic and prebiotic, Internet of Things (IoT) in monitoring the water quality in the farm operation, monosex culture and neo-female application also being applied in the aquaculture operation. The developments of these recent technology were towards achieving the sustainable aquaculture production, prevention of the disease outbreak, help in increasing the yield of crops harvested as well as towards the green environmental developments. This review paper emphasized on the most recent technologies developed in aquaculture in the past few years until these days. The developments of the new technology in aquaculture also in order to support the sustainable development goals (SDGs) proposed by the United Nation focused on SDG1 (no poverty) and SDG2 (zero hunger) from the increase of aquaculture production achieved through the recent developed technology. Ultimately, this review paper can generate new knowledge and information to the aquaculturist and aquafarmers on the new technologies and developments in aquaculture which could help benefit in the cultures operation and increase of production in the year future.

“…In addition, the immobilization of bacteria-microalgae consortium can improve the symbiotic interactions between the two species [135]. Many host materials such as alginate and luffa sponge have been reported for microalgae immobilization [136]. The stability of host and the immobilized microalgae is an important aspect especially for scaled up long-term application.…”

Pesticides have been identified as major contaminants of various waterways. Being classified as potential endocrine disrupting compounds, pesticides in aqueous system are highly hazardous to aquatic organisms and the ecosystem. The treatment of pesticide-containing wastewater can be performed through several means, but a wastewater treatment strategy which emphasizes both treatment efficiency and sustainability is a necessity of current time. In this context, bioremediation has been increasingly promoted as an alternative technique for the remediation of diverse pollutants. Particularly, bioremediation which involves the utilization of microalgae for the removal or conversion of pesticides to the harmless or less harmful compounds is becoming a trend. Exploiting microalgae as a tool for wastewater treatment presents multiple advantages over conventional treatment technologies, which include an opportunity to simultaneously treat pesticide-containing wastewater and nutrient recovery for microalgae cultivation as well as less formation of toxic sludge. This review discusses the roles of microalgae in mitigating pesticide pollution issue, while offering an opportunity for nutrient recovery from various wastewater sources. Based on the current laboratory studies, the use of microalgae bioremediation as a promising strategy for pesticide treatment has been rationalized. The establishment of more pilot scale studies is highly encouraged to further facilitate the implementation of this treatment approach for practical application.

“…Various wastewater treatment solutions have been proposed and implemented to mitigate the negative impacts of shrimp farming wastewater. For instance, membrane bioreactors, advanced oxidation processes, integrated recirculating aquaculture systems (RAS), micro and biological treatment methods (Meril et al, 2022;Ng et al, 2018;Visvanathan et al, 2008). These conventional wastewater treatment methods have been found to be ineffective for treating shrimp farming wastewater due to their high operating cost and low effectiveness for large-scale farming.…”

This study investigated a feasible model for treating actual shrimp farm wastewater at a pilot scale that could be applied to farms in the Mekong Delta area. The research was carried out using a hybrid constructed wetlands (HCWs) model, which included a floating constructed wetland (FCW, total area of 1,500 m2) and a horizontal sub-surface constructed wetland (HSCW, total area of 400 m2). The HCWs were cultivated with native plants including: Scirpus littoralis Schrab, Cyperus alternifolius, and Paspalum vaginatum. These plants are all adapted to the high salinity levels of shrimp farm wastewater. The system was operated for 30 days to treat shrimp farm effluent. Results indicated that the model effectively removed organic matter and nitrogen compounds from the wastewater. The treated wastewater had low concentrations of COD (10.0-15.4 mg/L), BOD5 (7.1-12.5 mg/L), NH4+-N (0.04-1.11 mg/L), and TN (0.17-1.83 mg/L), which met the reliable conditions for reuse or safety requirements for discharge to aquatic systems. The findings of this study have significant implications for the sustainable management of shrimp farm wastewater in the Mekong Delta area. The HCWs model is a feasible and effective way to treat this type of wastewater, and it could be adapted to other regions facing similar challenges.
