In recent years, the agricultural sector and localities have implemented many solutions, promulgated policies to encourage investment attraction, aquaculture development of advantageous products, such as white leg shrimp, Ben Tre clam, tilapia, etc.
Up to now, the province has developed 350 hectares of farming area of white leg shrimp in the direction of intensive and semi-intensive farming, accounting for 99% of the total farming area and only 1% of extensive farming. In the province, many farming areas for intensive white shrimp farming have been formed in Hoang Yen and Hoang Phu communes (Hoang Hoa); Quang Nham, Quang Chinh (Quang Xuong); Hai Ninh, Xuan Lam, Truc Lam, Thanh Thuy (Tinh Gia). The areas have been gradually adopted in the direction of VietGAP, many farmers have boldly invested in roofs, applying biofloc technology and commercial shrimp farming in cement tanks with a yield of 20-30% higher than normal farming. Most ponds have 2 crop/year, some up to 3 crops/year, average productivity is 15 tons / ha / crop; after deducting costs, give profits of VND 300 to 500 million. Every year, white leg shrimp in the province reaches the output of 3,000 to 3,500 tons of commodity. In tilapia farming, localities have actively converted a part of agricultural land of ineffective agricultural production into a model of tilapia farming according to VietGAP process, creating safety products, meeting the requirements of the domestic market and export-oriented.
Up to now, the province has expanded the area of tilapia farming for nearly 90 hectares, concentrated in districts of Ha Trung, Hoang Hoa, Quang Xuong, Nong Cong with productivity of 10-12 tons/ha. In addition, most of the freshwater aquaculture areas are released by tilapia in the form of intercropping. In order to encourage farmers, the Provincial Agricultural Extension Center organized many technical training courses for farmers about measures in the process of raising tilapia according to VietGAP process. Building models of tilapia farming associated with product consumption, helping to stabilize product consumption, creating food safety and hygiene products. According to the provincial agricultural restructuring project, in the period of 2015 - 2020, tilapia is identified as one of the four main breeding animals in the province's fisheries development and aims to achieve 1,000 hectares of unisexual tilapia farming for export by 2020, productivity reached 20 tons/ha, output of 20,000 tons; by 2025, it will be 1,500 hectares, with a yield of 20 tons/ha, a production of 30,000 tons, mainly in fish-rice areas with key infrastructure. This will be a source of raw materials for processing factories in the province, export to European countries.
Currently, relevant branches of the province and localities are focusing on developing concentrated intensive aquaculture areas applying high technology, synchronous infrastructure investment, scientific and technical application, advanced production process to expand production. Continue to mobilize people to convert areas of low-lying rice fields with low productivity to freshwater aquaculture intermingling tilapia. Developing advantageous products, such as white leg shrimp, Ben Tre clam, tilapia. Implementing the Plan No.101/KH-UBND dated May 11th, 2018 of the Provincial People's Committee on the development of the shrimp industry in Thanh Hoa province has become a large manufacturing industry, sustainable, adaptive to climate change and environmental protection. To support that direction, the province must continue to invest in the construction of the infrastructure of Dong - Phong - Ngoc aquaculture area (Ha Trung); the concentrated industrial shrimp farming area in Minh Loc commune (Hau Loc); upgrading infrastructure of concentrated industrial shrimp farming area in the province; encouraging enterprises and aquaculture production establishments to invest in expanding scale. At the same time, it should strengthen the state management of techniques and environment to limit environmental risks, epidemics, organize aquaculture production in the direction of linking the stages in the value chain.
