With over 50 years of deep-rooted experience in Dongshi aquaculture, the Tang family began farming eels during the grandfather's generation. Currently managed by the third-generation successor, Tang Xin-yuan, the business focused primarily on eel farming in its early days. Today, they have established their own brand, "Xin Xian Fish Farm," and transitioned to cultivating healthy seafood products using enzymes and probiotics. Currently, their primary aquaculture species are eel, white shrimp, and milkfish. Adhering to the principle of avoiding indiscriminate medication, they ensure that consumers can eat with peace of mind, and they were honored as a Traceability Champion in 2020 (Minguo Year 109).
