Aquaculture Climate Change 📍

"Land-based?" she asked.

In Bangladesh, the world’s fifth-largest aquaculture producer, sea-level rise threatens 50% of the coastal shrimp and prawn farms. Saltwater intrusion also contaminates freshwater aquifers used for hatcheries and processing. Farmers face a cruel irony: shrimp farming requires brackish water, but the precise salinity tolerance of black tiger shrimp (15-25 ppt) is narrow; too much freshwater from upstream dams, or too much salt from sea intrusion, both cause mortality. aquaculture climate change

Aquatic poikilotherms—cold-blooded creatures that cannot regulate their internal temperature—are exquisitely sensitive to water temperature. Each species occupies a thermal niche, a narrow band where growth, reproduction, and immune function operate optimally. As global sea surface temperatures rise (now approximately 1.0°C above pre-industrial levels, with some coastal regions warming 2-3°C), farmed species are being pushed beyond their limits.

Elias looked down. On the surface of the water, thousands of dead bait fish were floating belly up, victims of the hypoxia. The cobia were next. Farmers face a cruel irony: shrimp farming requires
