Climate-related risks to cage aquaculture in the reservoirs of Northern Thailand

Extreme or unusual weather is suspected to be a factor in mass mortality events of fish cage aquaculture in reservoirs. The most important climate-related risk was drought or low water levels, which also contributes the largest financial impact. Other climate-related risks perceived as important included: over-turning of stratified cooler and anoxic bottom water layers; prolonged cloud cover; sharp changes in temperature; heat waves; and cold spells. Risks are primarily managed at the farm level with techniques such as aeration, and reducing feed during stressful periods. This is a one-page draft for a larger article
