To provide scientific data on biological characteristics, breeding techniques, nursing and grow-out of Helmet Catfish - Cranoglanis bouderius (Richardson, 1846) in culture condition of Nghe An province. The success of the thesis will greatly contribute the basic knowledge to develop the seed production technique that can help to support the seed resources for commercial culture models and gene resources conservation for this species.

The collection of seed from planted trees in a Seed Orchard (SO) Seed Production Area (SPA) generally requires access to seed-bearing branches at heights. High lift machinery or climbing methods can be used to obtain required working heights. High lift machinery is the more efficient option, reducing the risks associated with climbing and chainsaw operation. In cases where high lift machinery is not available or too expensive, climbing is a viable option.
