Clam farming profits 3 billion VND

With an area of ​​6.3 hectares, an average yield of 18 tons/ha, an average annual revenue of over 6 billion VND, a profit of over 3 billion VND/year, creating regular jobs for 6 workers and seasonal jobs for 30 workers, that is the Ben Tre clam farming model of Mr. Pham Van Thiet, Mai Phu commune, Loc Ha district, Ha Tinh.

In 2002, Mr. Thiet applied for a bid for the land in the riverbank to exploit and raise clams. In the first years, he purchased and utilized the available local seed sources to release the seeds, but the yield was low, only 4-5 tons/ha. After studying the reality in Thanh Hoa and Nam Dinh, in 2010, he boldly invested in releasing Ben Tre clam seeds very effectively.



According to Mr. Thiet, in addition to diligence and hard work, breeders need to pay attention to the following issues:

- Choose a location (clam release site) with sandy or muddy sand (sand ratio 70 - 95%), choose a high tidal flat, calm wind and waves, flat farming ground, regular tides, not too long drying time (best from 4 - 8 hours). The thickness of the sand and mud layer is 10 - 15 cm, the average stable salinity is 15 - 25%o is most suitable.

- Choose the right season to release clams, avoid releasing clams in the rainy months from August to October; should release clams in February to harvest in July to August. Should release large clams to harvest quickly and reduce loss.

- Before releasing the seeds, it is necessary to clean the beach such as removing mollusk shells, filling in low spots, and leveling the beach.

- Choose good quality and disease-free clam seeds.

- Before mass release, the breed needs to be raised until it reaches a size of 200 - 300 fish/kg before being released into the breeding area.
