Researchers from MIT and USDA have developed a fish vaccination system using edible silk micro-needles that dissolve and release vaccines while swimming. This method could reduce stress on fish and labor costs in aquaculture. The technology has been tested on small fish, showing potential for broader application, but further development is needed before widespread use. The micro-needles can release vaccines quickly or over extended periods, addressing challenges in traditional vaccination methods that require sedation and individual administration. This innovation aims to improve fish welfare and enhance food quality.
