20.95%）。此壓力驅(qū)動空氣中的氧氣進(jìn)入水體，直到水體中的氧氣壓力等于空氣中的氧氣分壓。 </span> </p> <p> <span style="font-size:14px;">? 當(dāng)水體中的氧氣壓力等于空氣中的氧氣壓力時，氧分子進(jìn)出水體的凈值為零，也就是所謂溶氧達(dá)到平衡點，或稱為飽和點。 </span> </p> <p> <span style="font-size:14px;">? 影響氧氣水中溶解度的重要因子 </span> </p> <p> <strong><span style="font-size:14px;">- 大氣壓力 </span></strong> </p> <p> <span style="font-size:14px;">大氣壓力隨著地勢的增高而下降，因此地勢越高的地方，氧氣的溶解度</span> </p> <p> <span style="font-size:14px;">就越小。同一地點的大氣壓力每天都不大相同，如臺風(fēng)季節(jié)的低氣壓，</span> </p> <p> <span style="font-size:14px;">可能使氧氣的溶解度大為降低，因而導(dǎo)致養(yǎng)殖物缺氧而暴斃。</span> </p> <p> <strong><span style="font-size:14px;">- 鹽度 </span></strong> </p> <p> <span style="font-size:14px;">鹽度上升，則達(dá)到飽和點的溶氧量下降。</span> </p> <p> <strong><span style="font-size:14px;">- 水溫 </span></strong> </p> <p> <span

style="font-size:14px;">1、有機(jī)物質(zhì)降解不徹底，易產(chǎn)生氨氮、亞鹽、硫化氫、甲烷等有毒有害物質(zhì)。</span> </p> <p> <span style="font-size:14px;">2、有害菌、寄生蟲等病原菌容易出現(xiàn)大量繁殖現(xiàn)象。</span> </p> <p> <span style="font-size:14px;">3、低溶氧***動物的生長和正常的生理活動，攝食下降，抵抗力降低，易暴發(fā)疾病；嚴(yán)重者會導(dǎo)致大量死亡。養(yǎng)殖水體中的溶解氧應(yīng)保持在5-8mg/L，至少應(yīng)保持在4mg/L以上。若溶氧在4ppm時，蝦會吃料，但飼料利用率下降。若溶氧維持在2-3ppm，蝦出現(xiàn)停料，體質(zhì)變差。溶氧在2ppm以下時，蝦會因為窒息而死亡。</span>

style="font-size:14px;">造成水中溶氧不足的原因</span></strong> </p> <p> <span style="font-size:14px;">（1）高溫：氧氣在水中的溶解度隨水溫升高而降低，如在一個大氣壓下，水溫由10℃上升到35℃時，空氣中的氧在純水中的溶解度可以由11.27毫克/升降至6.93毫克/升，高溫會引起水體中溶氧降低。此外水產(chǎn)動物和其他生物在高溫時耗氧增多也是一個重要原因。</span> </p> <p> <span style="font-size:14px;">（2）養(yǎng)殖密度過大：水體中眾多生物的呼吸作用增加，生物耗氧量也增大。</span> </p> <p> <span style="font-size:14px;">（3）有機(jī)物的分解作用：有機(jī)物越多，細(xì)菌就越活躍，這種過程通常要消耗大量的氧才能進(jìn)行，因此容易造成缺氧。</span> </p> <p> <span style="font-size:14px;">（4）無機(jī)物的氧化作用：水中存在如硫化氫、亞硝酸鹽等無機(jī)物時，會發(fā)生氧化作用消耗大量的溶解氧。</span> </p> <p> <br />

style="font-size:14px;"><strong>（1）觀察水色和透明度：</strong>如果水色濃綠、暗綠且暗淡無光澤、或水中藻類少且老化，說明水體處于缺氧與亞缺氧狀態(tài)。水透明度小，藻多底層藻類光合作用不夠容易老化，加上藻多夜間耗氧多也會造成水中缺氧。 </span> </p> <p> <span style="font-size:14px;"><strong>（2）觀察水面上泡沫的多少：</strong>如果水面上的泡沫較多，且關(guān)停增氧機(jī)后泡沫久久不能消散，則說明水體處于缺氧與亞缺氧狀態(tài)。 </span> </p> <p> <span style="font-size:14px;"><strong>（3）觀察水中懸浮物的多少：</strong>如果水中懸浮物較多，也說明水體處于缺氧與亞缺氧狀態(tài)。</span> </p> <p> <span style="font-size:14px;"><strong>（4）晚上觀察魚蝦是否有爬邊、跳塘等現(xiàn)象：</strong>如果有魚蝦爬邊、跳塘等現(xiàn)象，也說明水體處于缺氧與亞缺氧狀態(tài)。 </span> </p> <p> <span style="font-size:14px;"><strong>（5）檢查pH值：</strong>如發(fā)現(xiàn)pH突降或逐漸下降，則說明水底缺氧。 </span> </p> <p> <span style="font-size:14px;"><strong>（6）有沒有氣泡溢出：</strong>早晚觀察水面有沒有氣泡溢出，如果有說明水底缺氧。 </span>
