style="text-indent:25px">水蛭具有水生性、野生性、變溫性和特殊的食性。根據(jù)水蛭的生活習(xí)性，要求選擇具有一定水域、溫暖、安靜、動(dòng)植物繁多的場(chǎng)所。噪音，尤其是震動(dòng)，對(duì)水蛭的生長(zhǎng)不利。因此，應(yīng)避開(kāi)車(chē)輛來(lái)往頻繁的交通沿線和有噪聲、震動(dòng)的飛機(jī)場(chǎng)、工廠等地區(qū)。地形的選擇應(yīng)以背風(fēng)向陽(yáng)、環(huán)境優(yōu)良為好。這樣，春秋季節(jié)可增加光照時(shí)間，延長(zhǎng)水蛭的生長(zhǎng)期，冬季可防風(fēng)抗寒，使水蛭能安全越冬。同時(shí)優(yōu)美的環(huán)境，夏季既可以防暑，又可以增加動(dòng)植物的***數(shù)量，為水蛭提供充足的餌料。我國(guó)淡水水域遼闊，因地域的差異各地水的質(zhì)量有明顯的區(qū)別。決定水質(zhì)質(zhì)量的理化指標(biāo)主要有溫度、鹽度、含氧量、pH 值、水色和肥度等。要考慮水源流至場(chǎng)地是否被污染。嚴(yán)重污染的水域，例如出現(xiàn)水顏色反常、渾濁度增大、懸浮物增多，洛陽(yáng)水蛭養(yǎng)殖、有毒物質(zhì)增加、發(fā)生惡臭等現(xiàn)象，則***不能使用，洛陽(yáng)水蛭養(yǎng)殖。同時(shí)還要考慮該水域在1

大塘養(yǎng)殖日常管理中，每天要檢查水位線的高低，及時(shí)進(jìn)行水位的調(diào)節(jié)，尤其陰雨天氣，要防止排水口堵塞，造成水位過(guò)高，夏季或干旱少雨季節(jié)水分蒸發(fā)也會(huì)造成水位下降，要及時(shí)補(bǔ)水，穩(wěn)定水位。 </p> <p> 水溫管理水蛭生長(zhǎng)適宜的水溫是15～35度，比較好水溫是20～30度，以28度為比較好。有條件的養(yǎng)殖場(chǎng)戶(hù)，要建造良好的水溫環(huán)境，可以搭建大棚提高水溫，覆蓋遮陽(yáng)網(wǎng)降低水溫，來(lái)防止春秋季早晚水溫下降，防止夏季水溫過(guò)高盡量不使水溫超過(guò)35度。小面積養(yǎng)殖池一般水位較低，一定要注意夏季水溫過(guò)高，發(fā)生水蛭中暑死亡。冬季只耍有越冬土層，水蛭可自然冬眠越冬，只要不結(jié)冰，水蛭冬眠就很安全。 </p> <p> 水質(zhì)管理是一個(gè)復(fù)雜又矛盾的過(guò)程，需要養(yǎng)殖者自己不斷地體會(huì)和總結(jié)；簡(jiǎn)單地說(shuō)，要保持良好的酸堿度，要有富裕的含氧量，要有豐富的微生物。淮南水產(chǎn)生態(tài)養(yǎng)殖公司1次畜禽血塊，但血塊中不能含鹽。</p><div

化學(xué)方法**常用的就是生石灰清塘。生石灰遇水后發(fā)生化學(xué)反應(yīng)，放出大量的熱能，中和淤泥中的各種有機(jī)酸，改變酸性環(huán)境，從而可以起到除害殺菌、施肥、改善底質(zhì)和水質(zhì)的作用。使用時(shí)可干池清塘或帶水清塘。帶水清塘一般是在總堿度、總硬度及pH值都偏低的池塘，及時(shí)合理地施用石灰；而池水和底質(zhì)中鈣離子濃度較大、堿度較高，則不必施生石灰；在有機(jī)質(zhì)貧乏的養(yǎng)殖塘不宜單施生石灰，否則會(huì)加劇有機(jī)物的分解，使有機(jī)物積存更少，池塘肥力進(jìn)一步下降，恢復(fù)更為困難。 </p> <p> 除生石灰外，還可選用化學(xué)復(fù)合型底質(zhì)改良劑。如一種主要成分為過(guò)氧化鈣(CaO2)的白色顆粒狀 “底層水質(zhì)改良劑”，投人水中能迅速增氧，促進(jìn)硝化作用，降低水中的氨氮、亞硝酸鹽、硫化物的含量，還能補(bǔ)充生物生長(zhǎng)所需的鈣，并使底質(zhì)疏松透氣，利用有機(jī)質(zhì)的完全分解。目前，一種新型亞硝酸根離子去除劑——亞硝酸螯合劑（BRT）及其鹽類(lèi)具有降解池水中亞硝酸態(tài)氮及氨態(tài)氮，螯合池水中的有機(jī)物，消除池水及池底中所含重金屬離子的污染等，可用做池塘土壤改良劑、底質(zhì)改良劑及底質(zhì)活化劑。

淤泥沉積速度與施肥、投餌等飼養(yǎng)管理措施直接相關(guān)。在生產(chǎn)中努力做到看水施肥，切忌過(guò)量；按照生態(tài)互補(bǔ)原則合理混養(yǎng)、密養(yǎng)；投飼量根據(jù)季節(jié)、氣候、生長(zhǎng)情況和水環(huán)境變化靈活掌握；在飼料中添加誘食劑、促長(zhǎng)劑等，增強(qiáng)水產(chǎn)動(dòng)物的食欲，促進(jìn)飼料營(yíng)養(yǎng)的吸收轉(zhuǎn)化，降低餌料系數(shù)，從源頭上解決排泄物對(duì)底質(zhì)和水質(zhì)的污染；防治水草(特別是絲狀藻)大量生長(zhǎng)，及時(shí)撈出過(guò)多或死亡的水草，以防腐爛變質(zhì)；有條件的可朝黑化區(qū)域潑撒煉鐵爐渣(一般1.5kg/m3)，以延緩黑化過(guò)程，并降低危害。 </p> <p> 另外，如果干池期較長(zhǎng)，可考慮把水產(chǎn)養(yǎng)殖和農(nóng)作物進(jìn)行輪作。這樣可以使淤泥更充分地干透，靠陸生作物發(fā)達(dá)的根系，使土壤充分與空氣接觸，有利于有機(jī)物的礦化分解，更好地改良池底，同時(shí)，還可以獲得農(nóng)作物本身的經(jīng)濟(jì)價(jià)值。另外，生長(zhǎng)的青綠作物和牧草還可作為池塘的優(yōu)良綠肥和魚(yú)類(lèi)的飼料。水蛭的自然越冬氣溫降至13度以下時(shí)，水蛭鉆入靠水面的潮濕疏松的泥土中越冬。威海水產(chǎn)養(yǎng)殖</p><p
