1、本科畢業(yè)設(shè)計(jì)本科畢業(yè)設(shè)計(jì)（20_20__屆）屆）魚(yú)類養(yǎng)殖網(wǎng)箱內(nèi)兩種寄生性纖毛蟲(chóng)研究魚(yú)類養(yǎng)殖網(wǎng)箱內(nèi)兩種寄生性纖毛蟲(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：隨著集約化水產(chǎn)養(yǎng)殖的持續(xù)發(fā)展，由纖毛蟲(chóng)引發(fā)的魚(yú)類寄生性疾病的發(fā)生率和危害性不斷提高，造成了巨大的經(jīng)濟(jì)損失。本文利用活體觀察和蛋白銀染色技術(shù)對(duì)兩種采自大黃魚(yú)養(yǎng)殖網(wǎng)箱中的纖毛蟲(chóng)進(jìn)行形態(tài)學(xué)研究。結(jié)果顯示這兩種纖毛蟲(chóng)是隸屬于腹毛目的多核擬雙棘蟲(chóng)及盾片異列蟲(chóng)，多

2、核擬雙棘蟲(chóng)的特征為：蟲(chóng)體細(xì)長(zhǎng)帶狀，口圍帶分成兩部分，3根額棘毛，1根口棘毛，中腹棘毛復(fù)合體由5個(gè)棘毛對(duì)及55根棘毛組成，1列左緣棘毛，5列右緣棘毛，611根橫棘毛，3列背部動(dòng)基列，約50個(gè)大核，無(wú)額前棘毛及尾棘毛。盾片異列蟲(chóng)的特征為：蟲(chóng)體橢圓形，口圍帶連續(xù)，3根額棘毛，2根額前棘毛，1根口棘毛，中腹棘毛復(fù)合體由67對(duì)棘毛組成，左右緣棘毛各15根，8根橫棘毛呈“U”字形排列，2根橫前棘毛，3列背部動(dòng)基列，約60個(gè)大核，無(wú)尾棘毛。關(guān)鍵詞：關(guān)
