Da Nang’s agricultural sector and localities have built many effective agricultural extension models, applied technical advances to production and promoted economic restructuring, significantly contributing to increasing the value of agricultural production towards changing farmers' production thinking and gradually developing agriculture in a modern and sustainable direction.

In Nam Thanh Village, Hoa Phong Commune, Hoa Vang District, the family of Ms. Nguyen Thi Ha has received a financial support from the Centre for Fishery - Agriculture - Forestry Extension under the municipal Department of Agriculture and Rural Development to implement a commercial farming model of bronze featherback. This is an aquatic species with high economic value, suitable for farming conditions in Hoa Vang District.

Mrs. Ha is raising about 4,000 bronze featherback along with 2,000 tenches and carps on an area of ​​1,000m².

“During the farming process, I was given very specific technical instructions from the centre’s staff to ensure the quality, quantity and yield of the harvest. Despite the difficulties in the weather, after nearly a year, the harvested fish yield was relatively high with about 1.1 tonnes of fish. In the next crop, I want to use advanced techniques to breed fish in cages to have a more specific assessment of economic efficiency” said Mrs. Ha.

Along with the family of Mrs. Nguyen Thi Ha, the centre has supported three other fish farming households in Hoa Khuong and Hoa Phong communes.

To ensure the quality of the seeds suitable for the local natural conditions, the Hoa Khuong Agricultural Experimental Farm under the Centre for Fishery - Agriculture - Forestry Extension has researched and developed a process for artificial reproduction of bronze featherback.

In 2023, about 16,000 seed fish were spawned, and they ensure quality with uniform size from 8-10cm, and healthy growth.

After nearly one year of farming, all households harvested about 1.1 tonnes - 1.5 tonnes of commercial fish. This is an imported fish species, so the farming process must follow a high-tech process, requiring farmers to regularly monitor, care for, and use appropriate feed with protein quality requirements to increase survival rate and ensure economic efficiency.

In 2024, the oyster mushroom production model of the family of Mr. Tran Phuoc Son in Hoa Khuong Commune was one of the models supported by the Centre for Fishery - Agriculture - Forestry Extension. In particular, the centre has supported 20 tonnes of raw materials, nearly 1 tonne of spawn, an automatic watering system, and 12 iron shelves; and a wood-fired steam boiler.

The centre has also supported and assigned staff to monitor and provide technical guidance to participating households to ensure the effectiveness of the model.

The raw materials used to grow mushrooms in the model are natural materials such as sawdust, rice bran and corn bran, which are carefully steamed, ensuring the VietGAP standard.

According to Mr. Tran Phuoc Son, a household participating in the model, previously, his family produced mushrooms using traditional methods, leading to a high loss rate and uneven product quality during harvest time.

Thanks to the active support of the Centre for Fishery - Agriculture - Forestry Extension, the Office of Agriculture and Rural Development of Hoa Vang District and the local authorities, his oyster mushroom production model has been invested in modern equipment, ensuring technical requirements, and improving output and product quality.

“We have processed the raw materials, packaged the mushroom spawn, cared for them and have produced the first batch of mushrooms. The loss rate due to contamination by mixed fungi after seeding is very low, only about 2%. In the first crop, the first harvest yield is estimated at about 2 quintals of fresh mushrooms. Currently, the model also creates jobs for 4 local workers," Mr. Son shared.

According to the Centre for Fishery - Agriculture - Forestry Extension, in addition to farming models, the unit has paid attention to organising training courses, and transferring scientific and technical advances, so that farmers have more knowledge to effectively apply to actual production at home to improve economic efficiency.

Mrs. Ngo Thi Thu Van, Deputy Director of the Centre, said that through training activities, demonstration models, and access to new scientific and technical advances in production, many participating farmers have grasped knowledge and techniques to apply in actual production. Thanks to that, the productivity and output of crops and livestock have initially improved.

With access to agricultural extension models, people have gradually changed their farming and production practices towards safety and sustainable development. Through the support of the agricultural sector, localities and other related units, participants have been linking with other households to create stable products to ensure prices and bring high economic efficiency towards large-scale concentrated agriculture and sustainable development.
