“…Many scholars have investigated rotational flows in aquaculture tanks, and hydrodynamic within aquaculture tanks have been measured or simulated to characterise and optimise various infrastructure designs 23–28 . The rotational flow in aquaculture tanks is a combination of circular rotational flow and vertical “bathtub vortex” flow controlled by the inlet and outlet water systems 29 . Other infrastructures directly affecting the flow pattern are the shapes of the tank and the layout of the aeration and oxygenation equipment, which play significant roles in improving the flow uniformity and preventing particle deposition.…”

Aquaculture intensification has emerged as a potential sustainable aquaculture strategy to contribute to the Food and Agriculture Organisation's United Nations Sustainable Development Goals associated with food security. Recirculating aquaculture systems (RASs) and biofloc technology systems (BFTs) are typical land-based intensive aquaculture facility models that have been widely researched and applied.The rapid growth of both systems has boosted human nutrition and the regional economy but has also caused concerns about animal welfare, ecological protection, water treatment effectiveness and public health. One of the key links between aquaculture and ecological issues is the treatment of harmful particulates in wastewater, particularly organic metabolic microparticles. These microparticles are derived from decomposition waste feed, faeces and biofilm and provide a surface for bacterial growth and proliferation. The increase in microparticle abundance can directly affect bacterial activity and abundance and adversely affect the environment. Furthermore, the decomposition and motion of these particles are related to the mechanical stress caused by the water flow pattern in aquaculture tanks. The internal configurations of the tank can control the hydrodynamic characteristics, such as the water velocity, uniformity, pressure and turbulence in aquaculture tanks, and thus influence the morphology of particles. This review analyses and discusses how macro-infrastructure influences the microenvironment in aquaculture tanks. These results provide a theoretical foundation and practical implications for improving the performance of aquaculture systems and environmental management in intensive aquaculture. It is concluded that optimisation of infrastructure design is key to improving the water flow patterns and self-cleaning performance of tanks and achieving high efficiency of RASs and BFTs, and is critical for the fulfilment of the Sustainable Development Goals in aquaculture.

“…Because the semi-closed systems are relatively new production technologies, the scientific peer-reviewed papers documenting their environmental functionality and biological performance are scarce. Most of the available literature describes and documents the engineering aspects, particularly the hydrodynamic properties and construction (Gorle et al, 2018;Klebert et al, 2018;Kristiansen et al, 2018;Chu et al, 2020;Su et al, 2021). Further, there are only a handful of publications on production capacity (Nilsen et al, 2017) and health, welfare, and performance (Rud et al, 2017;Balseiro et al, 2018;Nilsen et al, 2019).…”

Closed-containment (CCS) systems offer several advantages in controlling the production environment for Atlantic salmon (Salmo salar) aquaculture, especially at sea, where fish are more exposed to challenging environmental conditions. Here, we report the health and welfare of Atlantic salmon in FishGLOBE V5, a 3500 m3 semi-closed containment system. A group of 200,000 post-smolts was followed from a recirculating aquaculture system (RAS) facility, then for three and a half months in FishGLOBE V5, and three months after release in net pens. Fish samples were collected at four time points during the production period, while water quality was evaluated when the fish were in FishGLOBE V5. The water quality in FishGLOBE V5 was within the recommended range for salmon post-smolts. The mortality rate was 1.4% in FishGLOBE V5 and 4.9% in net pens. There was an increase in the prevalence of eye, snout and dorsal fin damages before the fish left the FishGLOBE V5 phase. The plasma level of magnesium was slightly elevated during this phase as well, indicating osmotic imbalance and stress. Histological evaluation of skin and gills showed sporadic cases of non-specific pathologies. In particular, the transitory stay in FishGLOBE V5 partially improved skin health, but not gill health. Gene expression profiling of some biomarkers showed that rearing fish in FishGLOBE V5 could influence the expression of genes involved in stress response, mucus production, and epithelial integrity. This study documented that rearing salmon for a certain period in FishGLOBE V5 during production affected different health and welfare indicators. These changes should be taken into consideration for the improvement of FishGLOBE V5 as a viable technology for post-smolt production at sea.
