The Kingfish Company

The Kingfish Company is a pioneer and leader in sustainable land-based aquaculture. We produce the yellowtail kingfish (also known as Ricciola/Hiramasa/Greater Amberjack) which is a highly versatile premium fish species, well known in the Italian and Asian fusion cuisines. Our operation is based on three core principles: sustainability, respect for our fish, and the environment. These key principles are at the heart of our design, activity, and technology decisions. Production of our fish is based on advanced recirculating aquaculture systems (RAS), which create the ideal growth environment for kingfish, offer optimal biosecurity, and limit the environmental impact. Animal welfare is paramount and our fish are grown without the use of antibiotics and vaccines. Operations run on 100% renewable energy, sourced from wind, solar, and biogas and the company’s facilities operate on seawater to avoid wasting precious fresh water. We are a fast-growing company and we are looking forward to welcoming new people into our team and exciting future.

Our values are: Innovation, Responsibility, Collaboration and Passion.
