Tridge summary

Vietnamese farmers have found success in raising cobia fish using high-density polyethylene (HDPE) plastic cages, as reported by local agricultural extension centers. These cages, with a diameter of 10 meters and a volume of 500 cubic meters, have demonstrated higher fish survival rates and healthier fish, leading to increased yields and profitability. The use of HDPE cages is particularly beneficial in areas hit by severe weather, as it can withstand high winds and waves, reducing risk and damage to farmers. From 2020 to 2022, the National Center for Agricultural Extension in Vietnam has implemented a project to promote this technology among marine farmers, with initial successes and plans to expand the training and implementation of these cages. This innovation is seen as a key strategy for sustainable and profitable marine farming, contributing to the economic value added by the seafood industry and the conservation of marine resources.

Sharing with the delegation, Mr. Nguyen Xuan Hoa (Van Thanh commune, Van Ninh district) excitedly said: "The HDPE plastic cage has a diameter of 10m, a volume of 500m3, and I have raised 2 times, in which, the first phase. I stocked 1,100 cobia, after about 8 months of raising fish, the average weight was 7kg/fish, the survival rate was from 89-92%, the harvest was over 6.5-7 tons, after deducting interest expenses. about 88 million VND". Mr. Hoa added: "Seeing efficiency, in the second phase, I released 7,000 cobia, harvested 9 tons, with the selling price of 125,000 VND/kg, a profit of 120 million VND. Farmed fish applying new technology are very healthy. So our fishermen can rest assured, the family is currently preparing to release the third batch." Similarly, Mr. Tran Ngoc Sy (local cobia farmer) happily said: "Through my research, I have boldly switched from traditional wooden cages to HDPE cages. I find that HDPE cages are more open and the fish are big. This is the first ...
