Hamachi Fish Sustainability 

Hamachi fish, also known as yellowtail, is a popular sushi ingredient that has gained widespread popularity in recent years. With the increasing demand for this delicious fish, concerns have arisen about the sustainability of its sourcing. In this blog post, we will guide you through everything you need to know about Hamachi fish sustainability and sourcing.

Sustainable Sourcing of Hamachi Fish

Hamachi fish is predominantly farmed in Japan and other parts of Asia. The farming of Hamachi fish is generally considered to be more sustainable than wild-caught fishing, as it reduces the pressure on wild fish populations.

Where is Hamachi Farmed in Japan?

Hamachi, specifically the species Seriola quinqueradiata, is commonly farmed in the Seto Inland Sea region of Japan, which includes the waters off the coasts of Okayama, Kagawa, and Ehime prefectures. These areas are known for their calm seas and optimal water temperatures, providing ideal conditions for Hamachi farming.

Challenges of Hamachi Farming

However, not all Hamachi fish farms are created equal. Some farms use unsustainable practices, such as:

Overcrowding: Overcrowding fish in small tanks can lead to disease outbreaks and higher mortality rates.

Antibiotics and Hormones: The use of antibiotics and hormones to promote growth and prevent disease can have negative environmental and health impacts.

Unsustainable Fishmeal: Some farms use fishmeal made from wild-caught fish, which can negate the benefits of farming by putting additional pressure on wild fish stocks.

Choosing Sustainable Hamachi

When choosing Hamachi fish, look for products that are labeled as sustainably farmed or have third-party sustainability certifications. Two major certifications to look for are:

Aquaculture Stewardship Council (ASC): The ASC certification ensures that fish are farmed responsibly, with minimal environmental impact and good social practices.

Global Aquaculture Alliance's Best Aquaculture Practices (BAP): BAP certification covers environmental and social responsibility, animal welfare, food safety, and traceability.

By selecting Hamachi with these certifications, you can be confident that you are making an environmentally friendly choice.
