Sustainable fishing practices are employed for well-managed hamachi fisheries with healthy stocks. Efforts are made to reduce unintended impacts such as bycatching of marine animals and seabirds, and emphasis is placed on minimizing effects on endangered or threatened species. Traceability of hamachi products from boat to plate is also ensured.
“Hamachi are well-adapted to a variety of marine environments, including brackish and freshwater areas, and their widespread distribution across the Indo-Pacific reflects their adaptability and importance in local ecosystems.”
Life Cycle and Reproduction
The life cycle of the hamachi, also known as yellowtail or amberjack, is a fascinating journey through various stages of growth and maturity. This species plays a crucial role in both commercial fisheries and aquaculture operations around the world.
Spawning and Early Stages
During the spawning season, adult hamachi congregate in specific areas, such as seagrass beds, to release their eggs. These eggs float to the surface, where they hatch into larvae that drift with the ocean currents. The hamachi larvae undergo a delicate transformation, gradually developing into juveniles as they transition to coastal habitats.
Growth and Maturity
Hamachi typically reach sexual maturity around 2 years of age, when they measure between 18-20 cm (7-8 inches) in length. As they continue to grow, some individuals can reach impressive sizes of up to 1.5 meters (5 feet) in length and 15 kilograms (33 pounds) in weight. The rate of growth and maximum size of hamachi can vary depending on factors such as their habitat, feeding opportunities, and environmental conditions.
“The life cycle of the hamachi is a complex and fascinating process that involves various stages of growth and development, from spawning to maturity.”
Hamachi Fisheries and Aquaculture
Hamachi, also known as yellowtail or buri, is an incredibly important commercial fish species. Global catches of hamachi are estimated to exceed 25,000 tons per year, with the fish highly valued in international markets, particularly in Japan where it has been a staple food for centuries.
In addition to wild-caught hamachi, the species is also extensively farmed, with an estimated 120,000 tons of farmed hamachi produced annually. The commercial importance of hamachi is reflected in the significant fishing and aquaculture industries dedicated to this popular seafood.
Commercial Importance
Hamachi’s commercial importance is undeniable. Over 80% of buri (the Japanese name for hamachi) on the market is farmed, with Kagawa Prefecture being the first in the world to successfully cultivate the species in 1928. Farmed hamachi can have a significantly higher lipid content, reaching 25-30%, compared to just 10% for wild-caught fish.
The demand for hamachi is so high that aquaculture facilities have been established around the world, including in Spencer Gulf, Australia, where the fish are bred in icy, crystal-clear waters and are ASC-certified for sustainability. In fact, over 150,000 tons of yellowtail fish are farmed annually through aquaculture, with the majority of production taking place in ocean pens in Japan and Korea.
“The aquaculture program for yellowtail at CCAR began in 2011, with rearing of yellowtail in tanks resulting in vigorous, fast-growing juveniles adapted to tank culture.”
The commercial significance of hamachi is undeniable, with both wild-caught and farmed varieties playing a vital role in global fisheries and aquaculture. As demand for this prized seafood continues to grow, the industry’s focus on sustainability and innovation will be crucial in meeting the needs of consumers worldwide.
Sustainability of Hamachi
The increasing global demand for hamachi has raised concerns about the sustainability of its populations. In Japan, where hamachi is most abundant, overfishing has been identified as a significant threat, with an estimated 85% of the catch coming from unsustainable sources. To address these sustainability concerns, efforts are being made to implement catch limits, improve fishing methods, and better regulate aquaculture operations.
The sustainable seafood movement promoting hamachi sustainability began in the 1990s. Restaurants like Mashiko, for example, transitioned to fully sustainable practices in 2009. However, the challenge remains, as typical high-end sushi bars usually offer around 15 fish options on their menus, many of which are unsustainable, such as Yellowfin Tuna, Bluefin Tuna, Eel, and Shrimp, which are often farmed with heavy use of antibiotics and growth hormones.
In contrast, sustainable sushi bars like Mashiko focus on offering a rotating selection of sustainable seafood, traceable to its origin. Factors considered for sustainable seafood selection include catch location, fishing practices, and environmental impact. Sustainable seafood options offered by Mashiko include Albacore Tuna, Salmon varieties, Geoduck, Octopus, and various local and Alaskan seafood choices.
Consumers are encouraged to ask questions about the origin, farming practices, feed types, and sustainability measures of seafood options. Recommendations include consuming smaller fish with high reproduction rates, like clams and mussels, and exploring new seafood options like snails, barnacles, and abalone.
However, the sustainability of hamachi production faces new challenges, such as the recent red tide epidemic affecting multiple areas of hamachi production in Japan. This has led to the loss of 240,000 pieces of 2-3 years old hamachi in one area, and the potential for a market price jump due to the impact on supply. Farmers are considering harvesting the remaining hamachi immediately for processing or storing in freezers, leading to an expected rise in hamachi prices and higher insurance premiums to ensure inventory security.
