摘要
研究了伊乐藻(Elodea nuttallii)对黄颡鱼(Pelteobagrus fulvidraco)池塘养殖水体的净化效果。结果显示,实验组(种植伊乐藻)与对照组相比,水体中总氮、总磷、化学耗氧量、叶绿素含量明显降低,水体透明度增加,黄颡鱼单产、成活率和成鱼规格分别提高17.21%、5.38%、14.27%。可见在保证产量的前提下,伊乐藻对黄颡鱼池塘养殖水体的净化有良好的效果。
The purification effect of Elodea nuttallii on water was studied in the ponds cultured Pelteobagrus fulvidraco. Results showed that Elodea nuttallii can improve the water quality by reducing the concentrations of TN, TP, COD and Chlorophyll a, and increasing transparency. Cultivating E. nuttallii in pond also can improve the growth and survival of P. fulvidraco, with an increment of per unit yield, 17.21% , survival rate, 5.38 % and average individual weight, 14.27%.
