Noro, Solomon Islands

Located in Noro, Solomon Islands SolTuna operates a 120 Mt per day tuna processing plant producing frozen tuna loins for the US and EU markets and canned products for the local and regional markets. Canned sales exceeded 700,000 cases of Solomon Blue and SolTuna brand products which are an important component of food security in the region. A fishmeal plant sells fish oil and 10 Mt of meal per day mainly for export to Australia and Asia. The company employs 2,000 workers, two-thirds of whom are women, in a rural environment, operating 2-shifts, 5 days a week.

SolTuna differentiates itself in relying on development and training of Solomon Islanders to manage and operate the company with less than 10 expats on staff in a very remote location. Offering non-traditional and better-paying jobs to women such as: fork lift driver, security guard, diesel mechanic, plumber and safety officer, has made SolTuna a leader in promoting gender equality. Women also hold several top management positions in operating departments such as Production and Quality Control.

Raw material, consisting of skipjack and yellowfin, is supplied by National Fisheries Developments Ltd (NFD) from a fleet of 5 purse seiners and 4 pole and line vessels.

Container lines provide service to Noro, on a 3-week rotation, allowing frozen loin exports in refrigerated containers to reach both US and EU markets.

In 2016 the Solomon Islands attained MSC certification for its’ archipelagic and EEZ FAD-free fishery allowing SolTuna to process MSC certified loins and canned product for export. In addition, the company is BRC, Kosher & Halal certified.
