Seapa Australia

What Seapa Australia does

SEAPA is an Australian manufacturer of plastic equipment purpose-built for single seed oyster farming. Founded in 1998 by Garry Thompson as a division of GARON Plastics and headquartered in Edwardstown, South Australia, the company designs, patents, and produces a basket-centric product platform — including the 15L, 25L, and GTX (20L, 12mm or 6mm mesh) baskets — supported by the STORMBREAKER clip and system for storm-resistant deployment, the REVO rotation system for tide-independent surface drying, and accessories such as End Caps and Float Cases. Core technical differentiation lies in patented oval basket geometry engineered to facilitate oyster rumbling, producing well-cupped shells and high meat content.

The business operates as a sales-led, hardware-manufacturing enterprise selling directly through regional offices in Australia, the USA, Europe, and Japan, supplemented by a Korea sales and marketing presence and exclusive Japan distribution agreements for complementary third-party systems (SED graders, Industrial Plankton photobioreactors, and EMYG INNOPURE purification). Pricing is quote-based and not publicly disclosed; merchandise (hoodies, gauges) is sold at unit prices. Customer segments are horizontal: commercial oyster farmers ranging from small family operations to larger enterprises, with a sub-segment focused on premium half-shell oyster production. Go-to-market combines farmer co-development, on-farm trials, trade shows (Tokyo Seafood Show, PCSGA, Salon de l'Agriculture), and the Global Oyster Farming Forum (GOFF).

SEAPA is privately held under GARON Plastics with no external venture capital disclosed, has grown to 11-50 employees, and reports more than 1.5 million baskets deployed across 20+ countries. The company has registered patents in Australia, the USA, and France covering its STORMBREAKER, EZ-Flip, and REVO systems, with additional patents pending.

Core offering

Seapa Australia designs, manufactures, and supplies plastic equipment for commercial oyster farming, including oyster baskets in multiple sizes, the STORMBREAKER wave-rated basket, and the REVO flip-farm system. The company also distributes complementary third-party aquaculture products such as SED oyster graders and Industrial Plankton algae cultivation equipment.

Product overview

SEAPA is an oyster farming equipment manufacturer founded in 1998, designing and producing a portfolio of plastic products specifically for oyster growers. The core product line centers on SEAPA oyster baskets (available in 15L, 25L, and 20L GTX sizes), the STORMBREAKER clip and system for storm-resistant deployment, and the REVO rotation system for surface-drying oysters without reliance on tides. The basket shape is purpose-designed to facilitate 'rumbling' — the tumbling motion that produces well-cupped oysters with clean hard shells and high meat content. Basket products are supported by End Caps, Float Cases, and a full accessories range. SEAPA also distributes complementary third-party equipment including SED Vision Graders, SED Twin Barrel Underwater Graders, SED Baggers (all manufactured by SED, Australia), and Industrial Plankton algae photobioreactors (Canada), which SEAPA sells alongside its own baskets to provide integrated single seed farming solutions. Four primary deployment systems are used: Adjustable Longline System (ALS), Fixed Systems, Subtidal Systems, and Floating Systems.

Partnerships

Five partnerships are on record, tiered core and minor.

• EMYG (France)coreChannel Partner/ Reseller/ Distributor · 21 August 2025SEAPA Japan became the exclusive Japan distributor for EMYG's INNOPURE shellfish purification and storage system. INNOPURE uses microbubble and patented water treatment technology to purify shellfish in short timeframes (e.g., reducing E. coli by 99% in 24 hours). The closed-loop circulation system minimizes water and energy consumption while maintaining product freshness for shipment.
• Industrial Plankton (Canada)coreChannel Partner/ Reseller/ Distributor · 11 July 2023SEAPA Japan secured exclusive import distribution rights in Japan for Industrial Plankton's algae photobioreactors. Industrial Plankton designs and manufactures bioreactors in Canada for producing clean, high-density algae for shellfish seed production. The equipment is used in aquaculture and biotechnology across 30+ countries. SEAPA Japan distributes this alongside their oyster farming equipment to provide comprehensive aquaculture solutions.
• SED (Size Graders)coreTechnology or IntegrationSEAPA distributes SED Vision Graders and underwater twin-barrel graders in Japan. The SED Vision Grader automates oyster sorting at high speed (4-7 oysters per second, 15,000-30,000 per hour) with 99% counting accuracy. The underwater grader classifies oysters while minimizing damage and stress, processing up to 100,000 oysters per hour per barrel.
• CAPENA (France)minorStrategic or Co-development PartnerCAPENA aquaculture engineer Cynthia Carpentier organized French farmer delegations to visit Australian oyster farms and SEAPA manufacturing facilities. The partnership facilitates knowledge exchange between French and Australian oyster industries, helping French farmers understand SEAPA basket systems and potentially adopt them.
• GARON Plastics (Australia)coreStrategic or Co-development PartnerSEAPA is a division of GARON Plastics, which manufactures SEAPA's oyster farming equipment. Garry Thompson founded SEAPA in 1998 through GARON Plastics. The factory in Adelaide produces baskets and equipment sold worldwide, with French farmers touring the facility as part of industry exchange programs.

• Akva Group: Global aquaculture equipment supplier offering cages, feeding systems, and software across multiple species. A broader incumbent that overlaps with SEAPA in the marine infrastructure and aquaculture services space.
• Innovasea: Large aquaculture technology company providing fish farming, monitoring, and tracking solutions. Comparable as a technology-driven aquaculture supplier with overlapping infrastructure and equipment offerings.
• Steinsvik (ScaleAQ): European aquaculture equipment provider with exposed/offshore farming systems, feeding, and biosecurity technology. Comparable as a broader aquaculture infrastructure supplier.

Emerging players

• Industrial Plankton: Canadian manufacturer of photobioreactors for algae cultivation used in shellfish and shrimp hatcheries. SEAPA is Industrial Plankton's exclusive Japan distributor, making them a partner and adjacent equipment peer.
• SED Graders: Australian maker of oyster vision graders and underwater sizing equipment distributed by SEAPA Japan. Comparable niche equipment peer for oyster post-harvest automation.
