What Stehr Szrl Pty Ltd does
Stehr Group is a Port Lincoln, South Australia-based, family-owned seafood company founded in 1972 that specialises in the offshore ranching and grow-out of Southern Bluefin Tuna (SBT). The company catches wild SBT using the purse seine method in the Great Australian Bight during the December annual migration, then holds the fish in offshore ranching operations in the Spencer Gulf for roughly six months before harvest. Operations are governed by international CCSBT quota allocations and Australian Fisheries Management Authority (AFMA) regulation, with every fish tagged and recorded under mandatory Catch Documentation Schemes.
The company's core technology stack centres on three proprietary capabilities: the purse seine fishing method (selective, low habitat impact), the low-stress Ike Jime harvesting technique for maximum flesh quality, and an underwater camera plus manual/remote-controlled feeding monitoring system used to assess and manage fish during the ranching period. The portfolio spans whole SBT (15-20kg up to 40kg+, gilled-and-gutted or head-and-gutted), chef-pack loins of 3-4kg vacuum-packed, and premium o-toro and chu-toro fatty cuts. Fresh product is shipped by air freight between March and September; super-frozen product (-60°C) is available year-round via sea freight. The group holds historic first Marine Stewardship Council (MSC) certification for a purse seine SBT fishery (April 2025), Friends of the Sea certification, and a consistent Level 1 Green EMP rating.
Stehr Group runs a sales-led, direct-distribution model. The Japanese market is the primary buyer, purchasing premium sashimi-grade SBT for o-toro and chu-toro applications; the company is actively expanding into the Chinese market through relationship-building led by Managing Director Marcus Stehr, and supplies global sushi and sashimi chefs through established direct relationships. Pricing is opaque and contract-negotiated, consistent with a premium, quota-constrained commodity. The business is tightly connected to adjacent parts of Australia's SBT industry, with Marcus Stehr serving as Executive Director of industry body ASBTIA and as a Director of ASX-listed peer Clean Seas Tuna Limited, and the family operates the Australian Maritime and Fishing Academy to train its own workforce.
