What QINGDAO QIHANG FISHING CAGE CO., LTD does

Qingdao Qihang Fishing Cage Co., Ltd (also operating as Qihang Innovation (qingdao) Marine Engineering Equipment Co., Ltd) is a privately held Chinese marine engineering equipment manufacturer headquartered in Qingdao. The company specializes in HDPE (High-Density Polyethylene) fish cage technology for offshore and deep-sea aquaculture, with its core platform comprising circular cages (up to 260m circumference and 150,000m³ effective volume), square cages, abalone/sea cucumber cages, and leisure fishing cages. Technical claims include wind resistance up to Grade 12, wave resistance up to 8 meters, and flow resistance up to 1.5 m/s. Supporting modules include UHMWPE/PE/nylon fishing nets with proprietary anti-fouling treatment, Recirculating Aquaculture Systems (RAS) integrating rotary drum filters, protein separators, biofilters, and UV sterilizers (98% effective sterilization rate), as well as automated feeding systems, underwater monitoring devices, and water quality instruments. Adjacent product lines cover floating leisure platforms, garbage interception facilities, breakwater structures, and end-to-end fish farm design services.

The company generates revenue through direct hardware sales and design services, organized into separate domestic trade and foreign trade divisions. Domestic distribution spans 15+ coastal Chinese provinces and municipalities, while international exports reach over 90 countries across Africa (17+ countries), Asia (13+ countries), and Europe (Finland, Croatia, Russia). Customer segments include commercial fish farmers, government fisheries programs (notably Belt and Road partner countries such as Nigeria, Mauritius, Ghana, Kenya, Pakistan, Kiribati, Fiji Marshall), tourism/leisure operators, and land-based RAS operators. Pricing is quote-based rather than publicly disclosed, with multi-year contract cadences. Long-term R&D partnerships with the Yellow Sea Fisheries Research Institute, Ocean University of China, and the Chinese Academy of Fishery Sciences underpin technology development. The company has produced over 20,000 cages cumulatively and holds 70+ patents across 20+ years of focused HDPE cage industry experience.
