To determine whether the seaweed Saccharina japonica can effectively utilize dissolved nutrients from Sebastes schlegeli fish cultures, a laboratory experiment was conducted in a static system for 7 days at ESFRI, NFRDI in Korea. The experiment included an S. schlegeli monoculture system and an S. schlegeli-S. japonica IMTA system. Saccharina schlegeli density (415±24 g; mean±SE) remained the same in all treatments, whereas seaweed density varied across treatments of 0, 0.5, 1, 2, and 3 kg (control and T1-T4, respectively). During the experiment, nutrient (NH4+ and PO43-) concentrations were measured at 24-h intervals. NH4+ concentration of the control group increased from 0.117±0.021 mg/L at the start of experiment to 5.836±0.904 mg/L at the end of experiment. NH4+ concentrations of each treatment were 3.004±0.040,2.086±0.133, 1.642±0.121 and 0.775±0.007 mg/L in T1, T2, T3, and T4, respectively, at the end of experiment. The concentration of PO43- exhibited a similar trend to NH4+ concentration. NH4+ and PO43- concentrations significantly decreased with increased S. japonica thallus density each day (P<0.05). The nutrient removal efficiency (NRE) and nutrient uptake rate (NUR) showed different relationships with changes in thallus density; NRE increased but NUR decreased as thallus density increased. Based on measured concentrations of NH4+ and S. japonica weight, regression analysis defined the relationship between as an exponential function, Y = 3.8165e-0.505X (R2 = 0.9552). Our results demonstrated that S. japonica can function as an efficient component in IMTA with environmental and potentially economic benefits for fish hatcheries.
Abstract
To determine whether the seaweed Saccharina japonica can effectively utilize dissolved nutrients from Sebastes schlegeli fish cultures, a laboratory experiment was conducted in a static system for 7 days at ESFRI, NFRDI in Korea. The experiment included an S. schlegeli monoculture system and an S. schlegeli-S. japonica IMTA system. Saccharina schlegeli density (415±24 g; mean±SE) remained the same in all treatments, whereas seaweed density varied across treatments of 0, 0.5, 1, 2, and 3 kg (control and T1-T4, respectively). During the experiment, nutrient (NH4+ and PO43-) concentrations were measured at 24-h intervals. NH4+ concentration of the control group increased from 0.117±0.021 mg/L at the start of experiment to 5.836±0.904 mg/L at the end of experiment. NH4+ concentrations of each treatment were 3.004±0.040,2.086±0.133, 1.642±0.121 and 0.775±0.007 mg/L in T1, T2, T3, and T4, respectively, at the end of experiment. The concentration of PO43- exhibited a similar trend to NH4+ concentration. NH4+ and PO43- concentrations significantly decreased with increased S. japonica thallus density each day (P<0.05). The nutrient removal efficiency (NRE) and nutrient uptake rate (NUR) showed different relationships with changes in thallus density; NRE increased but NUR decreased as thallus density increased. Based on measured concentrations of NH4+ and S. japonica weight, regression analysis defined the relationship between as an exponential function, Y = 3.8165e-0.505X (R2 = 0.9552). Our results demonstrated that S. japonica can function as an efficient component in IMTA with environmental and potentially economic benefits for fish hatcheries.
