Introduction
This question tests your knowledge of aquaculture systems, your practical experience, and your ability to evaluate and compare different techniques, which are crucial for optimizing production in aquaculture.
How to answer
What not to say
Example answer
“During my time at an aquaculture farm in Sicily, I worked with both pond systems and recirculating aquaculture systems (RAS). While pond systems are cost-effective, I found RAS to be more efficient for producing high-quality fish while minimizing water usage. For instance, we achieved a 30% increase in yield with RAS by optimizing water quality management and reducing fish stress. I believe that RAS is the future of sustainable aquaculture, especially in regions with limited water resources.”

Example answer
“At a farm in Tuscany, we faced a sudden outbreak of columnaris disease in our tilapia stock. I quickly assessed the situation and realized that poor water quality was a contributing factor. I collaborated with our vet to implement a treatment plan while also improving our filtration systems. Within two weeks, we saw a significant recovery in fish health, and post-outbreak, I initiated a new monitoring protocol that reduced future incidents by 40%. This experience taught me the importance of proactive health management.”

Example answer
“While working at a shrimp farm, I noticed a sudden drop in growth rates. I conducted a thorough analysis and found that the feed had a higher than expected moisture content, leading to spoilage. I coordinated with our supplier to ensure better quality control and switched to a more stable feed. As a result, growth rates returned to normal within a few weeks, and I learned the importance of regular feed quality checks.”
