本年度共進蒐集了台南七股2年生文蛤、新北市淡水河口文蛤、金門韓國文蛤及新北 市貢寮韓國文蛤，並陸續進行人工繁殖，並於體型達到2mm時，進行篩選移至田間池 進行培育養成。共篩選台南七股2年生文蛤50萬粒、新北市淡水河口文蛤30萬粒、金 門韓國文蛤2萬粒及新北市貢寮韓國文蛤6萬粒，放養於試驗場A5池中。並完成各種 苗05、10、15、20、25、30的72小時耐受鹽度試驗 。在15、20、25、30psu鹽度範 圍下台南七股2年生文蛤、新北市淡水河口文蛤、金門韓國文蛤及新北市貢寮韓國文 蛤皆有100%的潛沙率。在10psu下韓國文蛤則無法潛沙，但台南七股2年生文蛤有約 60±5%潛沙、新北市淡水河口文蛤有66±10%潛沙，顯示出金門和新北市韓國文蛤對低 鹽度耐受力較台南七股2年生文蛤、新北市淡水河口文蛤低。

This year, we collected Tainan Chigu 2-year-old clams, New Taipei City Tamsui River clams, Kinmen Korean clams, and New Taipei City Gongliao Korean clams. They were artificially reproduced one after another. When they reached 2mm in size, they were screened and moved to field ponds for cultivation. A total of 500,000 two-year-old clams from Tainan Chigu, 300,000 clams from theNew Taipei City Tamsui River clams, 20,000 from Kinmen Korean clams and 60,000 from Gongliao Korean clams from New Taipei City were screened and stocked in the A5 pond of the test site. And complete the 72-hour salinity tolerance test of various seedlings 05, 10, 15, 20, 25, and 30. In the salinity range of 15, 20, 25, and 30 psu, the two-year-old clams of Tainan Chigu, the freshwater estuarine clams of New Taipei City, the Korean clams of Kinmen, and the Korean clams of Gongliao in New Taipei City all have 100% buried sand rate. Under 10psu, Korean clams can not dive in the sand, but Tainan’s Chigu 2-year-old clams have about 60±5% of the buried sand, and , New Taipei City Tamsui River clams estuary clams have 66±10% of the buried sand. This shows that Kinmen and New Taipei Citys Korean clams have low salt The degree tolerance is lower than that of the two-year-old clams from Chigu in Tainan and the clams from the, New Taipei City Tamsui River clams estuary 。
