Marine Resources

Basic Approach

The Maruha Nichiro Group has a history rooted in the sea and spanning over 140 years. Precious natural resources and the natural life force of the sea have supported our growth.

With the increase in the world's population and the economic development of emerging countries, the demand for fish-eating is expected to increase in the future. In order to meet demands and protect marine resources, we will continue to contribute to the creation of a sustainable global environment and society through our business activities.

Main Initiatives in FY2020

Conducting Survey of Marine Resources

In order to implement sustainable procurement as a “sustainable corporate group,” the Maruha Nichiro Group conducted a survey on the products and raw materials of Maruha Nichiro Group companies to ascertain the current volume of seafood products handled and to evaluate the state of natural seafood resources between July and September in 2020.

Through this survey, we are aware that the strengths and challenges of the marine resources handled by the Maruha Nichiro Group have been clarified.

The Maruha Nichiro Group will examine ways to maintain or expand our strengths in the marine resources handled by the Group and strive to resolve the issues that have become apparent.

Sustainable Fisheries Partnership

Sustainable Fisheries PARTNERSHIP

Sustainable Fisheries Partnership works with the seafood industry toward a world where all seafood is produced sustainably and protects marine biodiversity. We commend Maruha for the extensive work you have done to map the sources of your seafood products. With sourcing from hundreds of fisheries globally, this was no easy task but necessary to be able to assess the environmental sustainability of fish stocks using SFP’s Fish Source database.

You have created a process to collect and monitor this sourcing information that will enable Maruha to maintain and improve the sustainability of its seafood products into the future. SFP also applauds Maruha’s transparent disclosure of the summary of this assessment and encourages you to use your leverage to improve fisheries identified as not yet sustainable.

As one of the world’s largest seafood companies, you (can) could have tremendous impact and drive important change in fisheries management and practices across the world. SFP recommends that Maruha join with existing fishery improvement efforts such as Supply Chain Roundtables and other pre-competitive collaborations – as it has done with SeaBOS – to ensure the long-term environmental sustainability of fisheries and the health of the ocean, and aligned the UN Sustainable Development Goal 14, life under water.

*1 Sustainable Fisheries Partnership (SFP): Founded in 2006, it is a marine conservation organization working toward a world where the oceans are healthy and abundant, all seafood is produced sustainably, and everyone has access to sustainable seafood. It leverages the power of seafood buyers and retailers in every part of the seafood supply chain to rebuild depleted fish stocks, reduce the environmental impacts of fishing and aquaculture, and address social issues and advance economic opportunities for fishers and their communities. The SFP Supply Chain Roundtable provides a forum to allow seafood suppliers to work together in a pre-competitive environment to promote and support improvements in fishery and aquaculture practices, management, and policy.

Use of Seafood Products Obtained through Sustainable Fishery/Aquaculture Certificates (MSC/ASC)

The Maruha Nichiro Group actively promotes the handling of MSC/ASC-certified seafood products. As of April 2021, Maruha Nichiro Corporation has handled 2,133 tons of frozen foods for household use bearing the MSC label in FY2020, which was less than the 2,520 tons in FY2019. The amount of foods bearing the ASC label handled in 2020 (period between January 1 and December 31) was approx. 19 tons, which largely decreased from approx. 150 tons in 2018. One of the main reasons was the drastic downturn in demand for prepared foods used in lunch bento boxes due to the COVID-19 pandemic. However, with the decreasing risks of infection, demand is expected to recover with the amount of handling quantities set to increase.

Increase Production of Egg-to-harvest Bluefin Tuna

Maruha Nichiro is a pioneer of egg-to-harvest bluefin tuna production. One of Maruha Nichiro’s Group companies, Aquafarm Co., Ltd., officially began shipping from its aquaculture farm specializing in farmed bluefin tuna in FY2019, and shipped 908 tons in FY2020. In order to strive for further production efficiency, we will temporarily reduce our annual shipping amount to approximately 500 tons, and further focus on the development of production technology.

As for yellowtail, we began shipping artificially hatched yellowtail in FY2020, and plan to start selling egg-to-harvest yellowtail in FY2022. In the future, we will continue to focus on the development of egg-to-harvest technology in contributing to the sustainable use of marine resources.

Feed Development to Reduce the Use of Fish Meal in Fish Feed

Maruha Nichiro’s Central Research Institute is undertaking efforts, including developing feed to reduce the use of fish meal in fish feed, as part of its initiatives to preserve marine resources. To make effective use of plant proteins such as soybeans, we are conducting research on fermentation processing of raw materials and the use of intestinal bacteria in cultured fish. We are carrying out fish feed testing with the test feed manufactured using the extruder granulator at the Central Research Institute.

Sakurajima Yougyo Introduces Fish Counting Machine with AI Tracking

We have worked with an outside contractor to develop an automatic counting system for the number of cultured fish that incorporates AI-based image processing technology. This machine began operation at Sakurajima Yougyo Co., Ltd., a Group c ompany that cultivates yellowtail and greater amberjack, in April 2020. Currently, there are six machines at Sakurajima Yougyo Co., Ltd. and two at Aquafarm Co., Ltd., with the plan to further expand going forward. (As of June 2021)  

By automating the counting of farmed fish on board offshore vessels, which used to be done manually, we have reduced the labor of employees who previously spent an entire day at sea counting visually, and improved efficiency by reducing human error. Not only is it employee-friendly and effective at improving efficiency, but it is expected to reduce the risk of marine pollution by allowing the amount of feed to be properly calibrated. Going forward, we plan to expand this technology to smaller juvenile fish and other fish species outside of yellowtail and greater amberjack.

Attending the Review Meeting on Optimization System for Seafood Trade as a Committee Member

As world demand for seafood products increases, it is said that in order to make the Japanese fishing industry a growth industry, it is necessary to establish a distribution framework for exports that is competitive in terms of both quality and cost.

Therefore, in order for Japan, as a major importer of marine products, to fulfill its international responsibilities in terms of thorough resource management, eradication of illegal, unreported, and unregulated (IUU) fishing, and promotion of exports, a legal system for catch certification, which is the starting point for traceability introduced in Europe, the United States, and other countries, is being developed.

In order to establish a more effective system, the Review Meeting on Optimization System for Seafood Trade was launched in September 2019, with the  Fisheries Agency’s Fisheries Administration Department’s Processing and Distribution Division as the secretariat. After considering preventive measures on the distribution of illegally acquired marine animals and plants, an act concerning regular results of domestic distribution of specific marine animals and plants was enacted and issued in December 2020. The same Act entrusts the specifics of the system, including specification criteria for first- and second-class specific marine animals and plants, as well as fish types included, to ministerial ordinances. Since it is essential to promptly discuss the details, the Review Meeting on Optimization System for Seafood Trade come into existence in order to discuss the contents of the system from both viewpoints of risk base and feasibility of implementation.
Maruha Nichiro Corporation has been attending this “Review Meeting on Optimization System for Seafood Trade” as a member since the first meeting held on May 17, 2021, following the “Investigative Commission on Catch Certification Systems” held from September 2019 to June 2020.

While we will continue to attend and be involved in this meeting, following enforcement of this legal framework, we will properly implement this system and forge ahead more powerfully with the construction of a sustainable seafood products distribution system for the entire Maruha Nichiro Group supply chain.
