“…As for the shellfish, Gao et al (2018) found that Haliotis discus hannai performed better at medium flow rate (300 L/h), with the highest specific growth rate and succinate dehydrogenase activity. Similar property was also found in scallops (Garcia-Esquivel et al, 2000), the specific growth rate and weight gain rate of scallops were highest when the flow velocity ranged between 5 and 10 cm/s, and could reach 2.5%/day and 190-200 mum/d respectively.…”

The cultivation of largemouth bass (Micropterus salmoides) in recirculating aquaculture systems (RAS) has become a growing trend. To ensure the welfare of juvenile largemouth bass in RAS, the effects of different flow velocities on their growth and physiology were explored, considering the flow velocity in real production. Following the stable water quality, juvenile largemouth bass with a body mass of 1.92 ± 0.38 g and body length of 4.50 ± 0.36 cm were reared at three different flow velocities of high flow (HF, 18 cm/s, 4.00 bl/s), middle flow (11 cm/s, 2.45 bl/s, actual average flow velocity of aquaculture) and low flow (4 cm/s, 0.90 bl/s) respectively. The whole experiment lasted 66 days. Results showed that different flow velocities had significant effects on the growth, digestive enzyme activities, antioxidant capabilities and immune capabilities of juvenile largemouth bass. HF can significantly increase the cumulative food intake, hepatosomatic index, weight gain rate, specific growth rate and condition factor of largemouth bass juveniles (p < 0.05). Flow velocity had no significant effect on feed conversion rate (p > 0.05), but the mean of feed conversion rate in HF group was the lowest. Under the HF condition, the activities of trypsin and amylase increased significantly (p < 0.05). For lipase activity, although no significant differences were observed between groups (p > 0.05), the mean of lipase activity increased as the flow velocity increased. With regard to the antioxidant and immune capacity, the malondialdehyde content in HF group significantly decreased (p < 0.05), and the immunoglobulin M content significantly increased (p < 0.05). From the above, following the HF velocity condition, fish growth, oxidative defence, immune capacity and digestive capacity could be improved to a large extent. To achieve higher growth, it is recommended circulating flow velocity of no less than 18 cm/s in largemouth bass at the juvenile stage (approximately 1.9-37.5 g and 4.5-14.5 cm long).

“…There have been significant research activities in relation to this species and investigations concerning broodstock conditioning, larval rearing and spat production under artificial conditions (Baqueiro, Massó & Guajardo 1982; Carvajal‐Rascón 1987; Morales‐Hernández & Cáceres‐Martínez 1996; García‐Esquivel, Parés‐Sierra & García‐Pámanes 2000). Nevertheless, in all cases, the limiting factor for aquaculture feasibility has been the supply of spat.…”

Nodipecten (Lyropecten) subnodosus (Sowerby 1835), the largest pectinid in tropical waters, has been continuously exploited. In support of sustainable development for this species, we started basic growth studies to establish aquacultural practices. N. subnodosus was cultured using triangular plastic cages in La Paz Bay (1995–1996) to describe growth and survival; we determined relationships between quantity of available food and growth and behaviour of body component indices. This culture system allows an isometric shell growth of scallops over 13 months; 56.8±2.1 mm height, 54.5±2.1 mm length and 23.0±1.1 mm width. Allometric growth was found between weight and height, length and width (survival was 44.3%). Body component indices and growth increased progressively until the summer of 1996 when all indices decreased negatively, influenced by high water temperatures. Gonad tissue developed during the first year. Gametogenic activity was evident, presenting the first spawn in summer. Particulate organic and inorganic matter and chlorophyll concentrations were relatively constant during the study, and there was no evidence relating these values to growth and body component indices. Culture of N. subnodosus is feasible in La Paz Bay. However, high water temperatures in summer reduced growth and survival rates.

“…The differences in living habits and ecological niche determine the difference of organism requirements for optimal flow rate (Domenici et al, 2008). For instance, juvenile turbot, Scophthalmus maximus , and largemouth bass, Micropterus salmoides , grow fastest at a flow velocity of 0.18 m/s (Chen, Ye, et al, 2021; Li, Ji, et al, 2019), while juvenile scallops, Nodipecten subnodosus , as filter feeders, are more suitable for growing in water with slow flow speeds (0.05–0.10 m/s) (Garcia‐Esquivel et al, 2000). Furthermore, a higher water velocity can make more particles suspend in the water, which is conducive to the filtration and removal of suspended particles.…”

Recirculating aquaculture system (RAS), as a modern highly intensive aquaculture mode, demonstrates the advantages of environmental friendliness, high efficiency and sustainable development, and has been widely used worldwide; they are also expected to be more widely applied in industrial aquaculture in the future as our natural resources are decreasing. However, RAS imposes very high requirements on operating conditions, including temperature, salinity, dissolved oxygen, pH, stocking density, light, feed composition, feeding amount, feeding frequency, and disinfection methods. Each factor is critical to the stable operation of the system. Therefore, to ensure the efficient and stable operation of RAS, its influencing factors must be controlled to within appropriate ranges. Herein, the factors affecting the operation of RAS are reviewed, and the mechanisms of their influence on the reared organisms are revealed, and suggestions on the control of these factors in aquaculture are proposed. This review can provide a theoretical basis for the further development of RAS.
