2、物為食，能防止沉積物中有機物含量的增加，相應地防止缺氧和氨濃度升高。哺乳動物血液中含有的呼吸色素載氧力（15-20 ml O2/100ml血液）高得多。與哺乳動物相比，這導致低載氧力（1-2 ml O2/100ml血液）。氧張力控制血紅蛋白與氧的結合和分離。鰓部的氧張力比血液中高，因此，氧結合到血紅蛋白上。三、將下列帶“工程”二字的詞組和句子譯成英語。 1土木工程；2. 生物工程；3. 火力工程公司；4. 工程局；5. 建筑工程公司；6.工程施工；7. 工程項目；8. 港口工程混凝土結構設計規范；9.遺傳工程。將下列詞組譯成英語。1. 暴雨；2. 煙癮極大的人；3. 睡得很死的人；4. 繁重的

29、的輪蟲：（1）將養殖的輪蟲過小孔徑的篩子，使小輪蟲與大輪蟲分開。（2）培養不同品系的輪蟲，因為輪蟲的規格由遺傳決定。第一種方法不能完全控制輪蟲的大小。過篩雖可將剛孵出的小輪蟲（neonate）與成蟲分開，但這些小輪蟲在魚苗池中，規格增加很快。所以，培養具有不同遺傳規格的輪蟲是更好的辦法。但這要求養殖者在孵化場中至少保存兩個以上的輪蟲品系。生產上用控制溫度和投喂不同餌料的方法大量培養不同規格的輪蟲。如夏季高溫時日本的小型輪蟲（S-型）居多，冬季以大型輪蟲（L-型）為主。七、翻譯下列單位的名稱中國科學院水生生物研究所中國海洋湖沼學會水生生物學報動物學報中國水產科學研究院廣東海大實業（集團）有限公司

46、The fish which，were black in color were transported to the market.將下列短文譯成英語。對幾種魚的研究表明，它們需要高度不飽和脂肪酸（polyunsaturated fatty acids, PUFA）。單一的亞麻酸（linolenic acid）就能滿足鮭鱒魚對必需脂肪酸的需要，但適宜生長還需要亞油酸（linoleic acid）。日本鰻鱺（Japanese eel）適宜生長也需要這兩種脂肪酸。亞油酸和花生四烯酸（arachidonic acid ）促進熱帶草食性齊氏羅非魚（Tilapia zillii）生長的作用比亞麻酸和二十

47、碳五烯酸（eicosapentaenoic acid）好。因此，PUFA中n-3和n-6系列脂肪酸對淡水魚類具有重要營養價值。既然二十碳五烯酸和二十二碳六烯酸（22:6 (n-6)）比亞麻酸能更有效地預防虹鱒必需脂肪酸缺乏癥，這些PUFA的鏈長也是滿足必需脂肪酸需要的重要成分。自首次在哺乳動物中發現第一種促性腺激素釋放激素（GnRH）以來，目前已在脊椎動物和原索動物中鑒定出了14種同功能（isoform）的促性腺激素釋放激素。這些同工物的名稱是根據初次測出其肽特殊序列所用的動物來命名的。大多數脊椎動物類群的cGnRH都與一個或多個GnRH型共存。脊椎動物的GnRH神經元系統（neuronal
