Professor Dave Little talks with early career researcher and GAA Innovation Award Winner Dr Simao Zacarias about his work on developing higher welfare practices for producing white-legged shrimp and on developments within the shrimp industry to reduce environmental impacts and contributions to greenhouse gas emissions.Some of the key points raised in the discussions are how:improvements in feed quality, source and management have been key approaches to reduce the impact of feed in shrimp farming GHG emissions. the adoption of annual mangroves forestation programs is reducing the impact of mangrove clearance on GHG emissions.the shift to intensive systems enables minimal use of land and water, and reduces the environmental impacts.adopting high welfare farming practices improve shrimp wellbeing and robustness.
