Taiwan Hard Clam: A Native Species and Global First

Hard clam cultivation began in Taiwan in the early 1920s. Around 1934, farmers began raising them in brackish water areas along the west coast and river estuaries. Hard clams gradually became an important part of Taiwan's aquaculture industry after 1970, when pond farming took hold.

Taiwan's hard clams were long believed to be Meretrix lusoria, introduced during the Japanese colonial period. It turns out they were native all along. In 2023, the Fisheries Research Institute under the Ministry of Agriculture published a paper in Molluscan Research confirming that Taiwan's farmed hard clams are not only a native species but also newly identified worldwide. They were officially named "Taiwan hard clam" (Meretrix taiwanica). All hard clams across Taiwan—whether in wild habitats, aquaculture farms, or traditional markets—are Taiwan hard clams.

According to the Annual Report of Taiwan Fisheries Statistics, hard clam farming represents the largest segment of Taiwan's shellfish aquaculture. Clean water, appropriate temperature, and proper pH levels are key to successful cultivation. Taiwan's major hard clam farming regions include Changhua County, Yunlin County, Chiayi County, and Tainan City.
