Monsoon Patterns, Viruses, and HABs Linked in Philippine Mariculture Area
In Bolinao, Philippines, a 2.5-month saxitoxin episode and a fish kill marked the 2022 season, yet the dominant phytoplankton were diatoms, not the toxin-producing dinoflagellate *Alexandrium* sp. that triggered the shellfish ban. Our sampling, using a PlanktoScope and 18S rRNA sequencing, revealed giant viruses from the Imitervirales and Algavirales orders coexisting with these blooms. While these viruses likely didn't directly cause the toxin event, network analyses suggest they influence plankton dynamics during HABs.
Wave-Powered Upwelling Boosts Kelp Growth in Gulf of Maine Study
In the Gulf of Maine, wave-powered upwelling could turn the tide for kelp aquaculture. A coupled modeling study, grounded in multiyear empirical data, finds that this approach can cool surface waters by an average of 1.0 °C and boost nitrate concentrations from June through September. The result? A potential yield increase of nearly 10 percent. This is pragmatic ocean intelligence: working with natural physical processes to address nutrient limitation and seasonal warmth.
China's Aquaculture: A Longitudinal View of Green Productivity Gains (2009-2023)
China's aquaculture sector is charting a measured course toward greener productivity, yet the data reveals a story of uneven progress. From 2009 to 2023, freshwater systems show a cumulative GML index near 1.099, while marine farming lags at roughly 0.96% annual growth. The gains we see hinge on technological progress, not broad-based efficiency. Scale and structure drive improvement, but transport access oddly hinders it. This is empirical, actionable insight for policymakers. The sector's future depends on targeted fixes, not blanket solutions.
