Enhancing Aquatic Primary Productivity Using the Underwater Fish Lamp Plus (UFL+): A Novel Approach to Marine Resource Optimization
The Underwater Fish Lamp Plus (UFL+) is a novel lighting technology designed to enhance aquatic primary productivity. This study investigates its effectiveness in increasing chlorophyll-a concentrations and promoting photosynthetic activity in marine ecosystems. The experiment, conducted from August to October 2023, evaluated the impact of UFL+ on primary productivity at different depths (5m, 10m, and 15m) by measuring chlorophyll-a levels and dissolved oxygen as indicators of photosynthesis. Results show that UFL+ significantly increased chlorophyll-a concentrations, with an average improvement of 25.7%. Photosynthetic activity, measured by changes in dissolved oxygen, also increased, with the greatest gains observed at shallower depths and under clear water conditions. The study found that optimal water temperature (25–27°C) and salinity (31–33 ppt) further enhanced the effectiveness of UFL+. However, UFL+ showed reduced effectiveness at greater depths, suggesting that light intensity adjustments or multi-wavelength systems could be explored for deeper waters. The findings highlight the potential of UFL+ for sustainable marine resource management, particularly in aquaculture and fisheries. Further research is needed to refine the technology and to assess its long-term ecological impacts.
