“…related decomposition processes: high levels of organic matter occurred together with high levels of NO 2 − -N, particularly in the later stages of cultivation (Milstein et al, 2001). However, the relatively short duration of this experiment, covering only part of the organism's growth cycle, may underestimate some of the problems typically occurring in the longer term (e.g., organic matter accumulation and disease outbreaks) (Dong et al, 2022). Shellfish survival in this study remained at 82%-87%, which is close to the survival rate of 90% reported by Washitani et al (2017).…”

“…The extraction rates of N and P were 1112.45 and 134.69 mg thallus -1 in the co-culture system of Sargassum hemiphyllum and oyster (Yu et al, 2016). Although the above approaches are promising for improving nutrient utilization efficiency, the inability to maintain the desired algal species during microalgal biofiltration, the high cost of RAS operation, and the rapid disease transmission in IMTA systems are recognized as non-negligible drawbacks (Dalsgaard et al, 2013;Dong et al, 2022;Mishra et al, 2023). Therefore, new avenues in aquaculture are urgently needed to recover nutrients from aquaculture systems into reusable bioresources to help close the nutrient cycle and make fishery production more sustainable.…”

Phosphorus (P) accumulation in aquaculture systems is damaging our environment beyond acceptable levels. Devising strategies to potentially recover P from aquaculture systems in a reusable bioresource form is paramount and aligns with circular economy policies. In this study, we constructed two culture models, monoculture (Mon) and tandem culture (Tan), using Exopalaemon carinicauda and Mercenaria mercenaria. By monitoring the performance of rearing organisms, P dynamic patterns, and pollutant emissions, we found that: i) Compared to the Mon system, the Tan system demonstrated no differences in the performance of E. carinicauda and M. mercenaria, suggesting that the Tan model was viable in terms of fishery yield; ii) P in the Tan system could be efficiently recovered and removed from water and sediment, as indicated by the lower phosphate concentration in water (0.01 mg L−1), and the decrease in labile P in surface sediment (from 0.04 to 0.02 mg L−1). A combination of assimilatory and dissimilatory processes, mediated by phototrophic (bait-microalgae) and heterotrophic organisms (bivalves), appeared to be the primary mechanism for P utilization and removal; iii) The Tan system reduced pollutant emissions four times lower than the Mon system due to its minimal tailwater discharge (10%, 230 L). The emissions of total P, phosphate, total organic carbon, ammonium, and chemical oxygen demand from the Tan systems were 19 mg m−2 d−1, 2 mg m−2 d−1, 2 g m−2 d−1, 38 mg m−2 d−1, and 11 g m−2 d−1, respectively, 1.3, 1.7, 1.4, 1.3, and 1.2 times lower than those from the Mon systems. The eco-friendly Tan culture model fully exploited the resources of pond culture, a solution with environmental and health co-benefits for P recovery and emission reduction.

Meeting the global demand for aquatic products while maintaining sustainability is a critical challenge. This review article examines global practices of land-based aquaculture systems that could be implemented in the EU, as the EU has not yet fully realized its potential in developing the aquaculture sector. Therefore, the article examines different aspects (aquaculture systems, technological solutions and improvements, and best management practices) in achieving sustainable aquaculture and emphasizes the need for innovation and cooperation in the face of increasing environmental concerns and resource constraints. There is no one-size-fits-all solution for the sustainable intensification of aquaculture. The way forward requires a combination of different and improved-upon technological solutions complemented by technological innovation and better management practices. The sustainability of aquaculture requires a broader application of the ecosystem approach to aquaculture and the promotion of energy and resource efficiency measures in aquaculture systems.

“…is very important as bio-indicator of the aquatic environment (Khalil et al, 2021;Zhou et al, 2022). A good aquatic environment will affect the productivity level of aquaculture (Dong et al, 2022). Conversely, a bad aquatic environment will make fish susceptible to stress and die (Britton et al, 2023).…”

Chlamydomonas spp. and Chlorella spp. are plankton genera that can be used to determine the level of balance in the aquatic environment. The purpose of this study is to determine the abundance of plankton Chlamydomonas spp. and Chlorella spp. and its relation to the clinical performance of red tilapia in silvofishery ponds. The research method used is an ex post facto causal design with random sampling. The results showed that the water quality in the silvofishery ponds was very good, except for the nitrate parameters of 0.00-1.50 mg/L and salinity of 2-11 gr/L, which exceeded the quality standards. In the silvofishery ponds, 5 plankton classes were found, namely Chlorophyceae, Cyanophyceae, Chrysophyceae, Protozoa, and Dinophysis, consisting of 15 genera. The dominant class Chlorophyceae had an abundance of 2.88E+06 cells/ml. The class Chlorophyceae is dominated by Chlorella spp. (2.63E+06 cells/ml) and Chlamydomonas spp. (2.20E+05 cells/ml). The abundance of Chlamydomonas spp. in silvofishery ponds is closely related to phosphate solubility (0.988). Based on observations of clinical symptoms on the eyes, gills, and fins of fish, no disease infections or physical abnormalities were found in the fish cultured in silvofishery ponds. Fish tend to live well with a growth rate of 0.44 g/day. The aquatic ecosystem of the silvofishery pond, which is dominated by the plankton Chlorella spp. and Chlamydomonas spp., had a good effect on the performance and condition of the farmed fish. This study concludes that the abundance of Chlamydomonas spp. and Chlorella spp. was very dominant compared to other plankton genera. The presence of Chlamydomonas spp. and Chlorella spp. illustrates good and stable environmental conditions in silvofishery ponds, followed by no clinical signs of disease infection in the fish reared during the study period.
