    摘要: 豐年蝦(Brine shrimp, Artemia sp.)由於它容易取得,孵化簡單、大小適當與營養價值極高,因此至今在水產養殖上仍極廣泛的被使用在孵育魚貝幼苗的最佳生物活餌料。餵食豐年蝦後之幼魚貝苗其存活率皆比餵食人工合成或單一飼料之存活率為最高,此為除了其為活生之餌料外,其優越之營養素成份、比率與種類為主因;其營養素中除了蛋白質與碳水化合物外,尤其多元不飽合脂肪酸之種類為幼魚貝苗賴以合成為本身之脂肪酸及存活之主要營養素來源,又由於豐年蝦之品質與來源之差異,有可能導致餵食後幼魚貝苗其存活率之影響,因此本研究欲探討不同豐年蝦品種之脂肪酸種類比較。分析結果發現從Reference Artemia cysts (RAC)之豐年蝦比較其他兩種San Fransico Bay (SFB)與Great Salt Lake (GSL)有極顯著較高之16:1ω7 (13.30%),18:1 (36.10%) 與20:5ω3 (7.44%)脂肪酸百分比組成,然而San Fransico Bay (SFB) and Great Salt Lake (GSL)之Artemia卻比Reference Artemia cysts (RAC)有顯著較高之18:3ω3。
    Due to the availability, hatchery, size and high nutritional values of brine shrimp, Artemia sp., this zooplanktonic specie has been widely used as the best live diets for the rearing of the larval fish in aquatic culture. By feeing with the live Artemia nauplii, the survival percentages are normally higher than other feeding with artificial or mono diets. This is mainly due to the significant various nutrient types, profiles and types. Other than proteins and carbohydrates, polyunsaturated fatty acids are the main nutrient sources for providing the main sources in order to keep a good survival of aquatic larvae. Therefore, the quality or geographic origin differences of the Artemia nauplii may result a survival effect on the fish larvae. This study is conducted to compare the various fatty acid profiles on three different Artemia sp. Results show that relatively high of fatty acids are found in 16:1ω7 (13.30%), 18:1 (36.10%) and 20:5ω3 (7.44%) from Reference Artemia cysts (RAC) compared to the other two Artemia specie. However, a significant higher of 18:3ω3 are found to be from the Artemia of San Fransico Bay (SFB) and Great Salt Lake (GSL).
