Nagaland University researchers develop eco-friendly fishing trap

DIMAPUR — A research team from Nagaland University (NU) has designed and patented an innovative fish trap called ‘BR fishing trap’ made entirely from locally-available bamboo and plastic threads.

In a press release, the university stated that the eco-friendly, low-cost device is uniquely built to support fishing in hill streams and cage culture fish farms, offering a promising alternative to expensive, market-based gears.

The innovation has been patented in the United Kingdom (patent number 6399114, awarded on 25/10/2024), strengthening Nagaland University’s growing reputation for research-driven societal solutions.

The work was carried out by Dr. Pukhrambam Rajesh Singh, Assistant Professor of the Department of Zoology, and Prof. Bendang Ao, Department of Zoology. Their research focused on studying the diversities of Ichthyofauna and plankton in the Milak and Dikhu rivers of Mokokchung district.

During the study, the team faced challenges as many fishing gears were either expensive or unavailable in local markets. This led the researchers to collaborate with local bamboo weavers, leading to the creation of the BR fishing trap.

Congratulating the researchers, Prof. Jagadish K Patnaik, Vice Chancellor of Nagaland University, said, “Our University is committed to solutions that connect research with real-life challenges of our people. The BR fishing trap is not just an innovation but also a symbol of how indigenous knowledge and local resources can drive sustainable growth. This invention will benefit communities directly while showcasing Nagaland’s contribution to global sustainable practices.”

Unique features of the BR fishing trap

•             Four entrances: Unlike most traps with one or two entry points, the BR fishing trap has four circular entrances (one on each side), making it highly efficient. These four entrances are 6 inches in diameter each, one on every side. Notably, one of these entrances is removable, making it easy to release fish and clean the trap.

•             Box-shaped and lightweight: Measuring 22x8 inches, it is easy to install, transport and clean.

•             Durable and pest-resistant: Bamboo strips and plastic thread construction make it robust, long-lasting, and resistant to rot.

•             Versatile use: Effective in both rivers and cage culture fish farms.

Highlighting the unique aspects of the innovation, Dr. Pukhrambam Rajesh Singh said, “Fishing in our hill streams often depends on market-based gears which are costly and not always suitable. By designing this trap with local bamboo weavers, we created a solution that is not only cost-effective and durable but also empowers local craftsmanship. We hope it inspires more community-driven innovations.”

Beyond its ecological advantages, the BR fishing trap also holds strong socio-economic potential. By relying on locally available materials and skills of traditional bamboo artisans, it can encourage regional enterprise development, job creation, and livelihood security in fishing communities across Nagaland and beyond, the release stated.
