摘要: 为了探讨不同微藻饵料对卤虫生长及养殖水环境的影响,采用单独和混合培养的方式,以3种海水微藻(球等鞭金藻、塔胞藻和杜氏盐藻)为饵料饲养卤虫,测定卤虫体长、体重等生长指标及养殖水体pH、温度、盐度、溶解氧的变化。试验结果表明:不同微藻饵料搭配养殖卤虫的效果差异明显,水环境变化也存在较大差异。其中球等鞭金藻和塔胞藻混合饲养的卤虫效果最为理想,卤虫的存活率高,相对增长率大,水环境维持稳定,为卤虫生长提供了良好的水环境。因此在水产渔业生产上,球等鞭金藻和塔胞藻配合形成的饵料可作为增加卤虫存活率和相对增长率的适口饵料进行推广应用。

Abstract: In order to investigate the effects of different microalgae bait on the growth of Artemia parthenogentica and the environment of aquaculture, this experiment used single and mixed culture methods to feed Artemia with three kinds of seawater microalgae, Isochrysis, Tadpole and Dunaliella. Determination of growth indicators such as body length and body weight of Artemia, and changes in pH and dissolved oxygen of cultured water were studied. The experimental results showed that the effects of different microalgae bait on the culture of Artemia were obvious, and the water environment changes were also different. The effect of Artemia was the best in the mixed culture of Isochrysis galbana and Tadpole algae. The survival rate of Artemia was high, the relative growth rate was large, and the water environment was stable, which provides a good water environment for the growth of Artemia in Bohai Bay. Therefore, the bait formed by the combination of Isochrysis galbana and Tadpole algae can be promoted and applied in the production of aquatic fishery as suitable bait for increasing the survival rate and relative growth rate of Artemia.

Key words: Artemia parthenogentica, Isochrysis galbana, Tadpole algae, Dunaliella salina, survival rate, relative growth rate
