Abstract
Abstract
Conditions for photosynthetically generating high concentrations of dissolved oxygen were evaluated using sterile Ulva lactuca. During culture under, we controlled the following conditions such as aeration, NO3-N concentration, and population density. As a result, it reached approximately 3.8 times its saturated concentration 3 hours after cultivation. Here, we show that this high level of dissolved oxygen can be maintained if the seal on the supersaturated dissolved oxygen seawater is properly maintained. Seawater with high levels of dissolved oxygen is essential for growing oysters and vivalve which also prefer 20-25℃ of growth temperature. Therefore, we have developed a new system for simultaneously growing sterile Ulva sp. and culturing oysters.
