Reader Briefing

Thai Minister orders an urgent investigation into marine life deaths at Tako Estuary, Chumphon province, following reports of a red tide and critically low oxygen levels.

•Minister Suchart ordered an investigation into marine life deaths and discolored seawater at Tako Estuary, Chumphon province.
•Initial findings indicate a phytoplankton bloom and low dissolved oxygen levels as potential causes.
•The Department of Marine and Coastal Resources is assessing the situation's impact and mitigation strategies.

Overview

•On June 2, Minister Suchart ordered an inspection of marine life deaths at Tako Estuary.
•The Department of Marine and Coastal Resources (DMCR) has dispatched a team to survey and test water quality.
•The investigation was prompted by the discovery of dead marine life and discolored seawater at the Tako Estuary.
•Initial surveys revealed reddish-brown seawater with a foul odor and deaths of various marine species, primarily fish.
•Phytoplankton density was found to be 13,430 cells/liter (Pseudo-nitzschia spp.), a level capable of causing significant discolored water events.
•Dissolved oxygen (DO) levels in the area were as low as 3.95 mg/L in fish cages, which is considered critically low for aquatic life.
•The phytoplankton bloom may be contributing to reduced dissolved oxygen levels, particularly at the bottom, affecting aquatic life.
•Algal bloom can occur when phytoplankton density exceeds approximately 10,000 cells/liter, depending on species and environmental conditions.
