Sustainable development of shrimp farming thanks to Biofloc technology

QTO - With a relatively large area of ​​brackish and saltwater aquaculture, Quang Tri province has great potential to develop shrimp farming in a sustainable direction, achieving high economic efficiency and protecting the environment through the application of high technology and advanced production processes. In that context, the project "Application of Biofloc technology to build an industrial-scale white-leg shrimp (Litopenaeus vannamei) farming model in Quang Tri province" implemented by Hoang Minh Nguyen Company Limited is expected to open a new direction for the province's shrimp farming industry, which is still facing many difficulties.

Mr. Hoang Minh Nguyen, Director of Hoang Minh Nguyen Company Limited, shared that previously, shrimp farming using old technology resulted in low productivity, high costs, low profits and affected the environment. With Biofloc technology, clean water, reduced water changes, higher profits, reduced costs, shrimp eat well, grow quickly and evenly. With the ability to manage water quality, reduce excess food and increase survival rate, Biofloc technology is considered a sustainable solution, in line with the green economic development orientation of the province. The general goal of the project is to build a model of white-leg shrimp farming using Biofloc technology to achieve high productivity, outstanding economic efficiency and sustainable development of shrimp farming in Quang Tri; at the same time, creating jobs and increasing income for people.

The commercial white-leg shrimp farming model is implemented at 2 locations with an area of ​​4 hectares. Of which, the concentrated model at Hoang Minh Nguyen Company Limited (Ninh Chau Commune) has a scale of 2 hectares and the dispersed model at households (Ninh Chau Commune) is 2 hectares. The National Center for Northern Seafood Breeding is the unit transferring the technical process of commercial white-leg shrimp farming using Biofloc technology.

During the implementation process, the project team has received, mastered and successfully transferred key technical processes, including: Designing ponds using Biofloc technology, renovating ponds, selecting high-quality whiteleg shrimp breeds, creating and managing beneficial microorganisms (Biofloc), along with care and disease prevention processes without using antibiotics. Based on the received processes, the project has built two experimental farming models. In addition, the project has organized technical training courses for local officials and people, combining theory and direct practice at the models, contributing to improving the capacity to access new technologies for the aquaculture community.

The project completed 100% of its target, in the concentrated model, exceeding the targets of output (reaching 55.12 tons, exceeding the target by 10.2%), productivity (from 26.24-29.01 tons/ha, exceeding more than 2.5 tons/ha) and survival rate (from 79.8%-80.2%). Biofloc technology proved to be highly effective, increasing productivity, reducing costs and ensuring clean products. The model brought in a profit of 1.57 billion VND/ha/crop (50%-90% higher than the traditional model), while creating jobs, improving farmers' qualifications and reducing environmental pollution. In addition, the project has trained 4 technicians proficient in Biofloc and trained 100 farmers, creating a qualified workforce for the locality; creating jobs for 8 regular workers, 8-10 seasonal workers, improving income and producing clean shrimp, reducing environmental pollution. Despite difficulties due to natural disasters and the market, the project has contributed to laying the foundation for sustainable shrimp farming in Quang Tri . According to engineer Tran Minh Hieu, Project Manager, the research team will rely on the success of the model to learn about the natural conditions, soil, and climate of the locality, thereby compiling a suitable document to help people build a safe farming model, increase productivity, reduce costs and especially create clean shrimp, bringing higher economic value.

The project's practical experience shows that the white-leg shrimp farming model using Biofloc technology has laid an important foundation for the transformation of the rural economic structure in Quang Tri, promoting sustainable shrimp farming and adapting to climate change. The initial success of the model shows the potential for replicating Biofloc technology in white-leg shrimp farming not only in Quang Tri but also in other localities in the country and the region.
