1、本科畢業(yè)設(shè)計(jì)本科畢業(yè)設(shè)計(jì)（20_20__屆）屆）三種貝類養(yǎng)殖中的有害性纖毛蟲(chóng)研究三種貝類養(yǎng)殖中的有害性纖毛蟲(chóng)研究所在學(xué)院專業(yè)班級(jí)生物技術(shù)學(xué)生姓名學(xué)號(hào)指導(dǎo)教師職稱完成日期年月摘要摘要：近年來(lái)，在市場(chǎng)經(jīng)濟(jì)的引導(dǎo)下，水產(chǎn)養(yǎng)殖得到了快速發(fā)展。貝類養(yǎng)殖是我國(guó)水產(chǎn)養(yǎng)殖的重要組成部分，但是隨著貝類養(yǎng)殖密度和養(yǎng)殖規(guī)模的不斷擴(kuò)大，養(yǎng)殖病害亦日趨嚴(yán)重，已成為制約貝類養(yǎng)殖業(yè)發(fā)展的重大障礙。纖毛蟲(chóng)原生動(dòng)物廣泛存在于各種水體，某些類群是養(yǎng)殖業(yè)種的危害種或潛在危害

2、種。由于纖毛蟲(chóng)病死亡率高，流行范圍廣，可不同程度地給宿主造成危害，故對(duì)其研究既具有理論意義，又具有經(jīng)濟(jì)價(jià)值。本文主要研究貝類養(yǎng)殖水體中的三種有害性纖毛蟲(chóng)——蘭氏偏體蟲(chóng)Dysterialanceolata、北歐林奇蟲(chóng)LynchellaNdica、少齒蓬管蟲(chóng)Chlamydonyxpaucidentatus。根據(jù)活體觀察及蛋白銀染色法對(duì)其形態(tài)學(xué)、纖毛圖式進(jìn)行了綜合描述。關(guān)鍵詞關(guān)鍵詞：貝類養(yǎng)殖；纖毛蟲(chóng)；形態(tài)學(xué)；纖毛圖式。Abstract:Inr
