中文摘要:

      针对目前海珍品增殖的需要，进行了刺参人工鱼礁增殖实验研究。实验共分为3部分进行，即无模型礁与有模型礁的对照实验、同种材料5种形状模型礁以及两种不同材料的三角形孔洞长方体礁对比实验。实验结果表明，各种形状的模型礁投入到养殖实验池中后对刺参的平均聚集率与不投放模型礁相比差异极显著；同为水泥制的5种模型礁投入后，圆管形模型礁对刺参的平均聚集率最高，与其他4种模型礁相比差异显著；两种不同材料的三角孔模型礁投入后对刺参的平均聚集率差异不显著，水泥制模型礁高于大理石制；利用石块投石造礁对刺参也具有一定的聚集效果。

英文摘要:

      The experiment on artificial reef enhancement of Apostichopus japonicas was carried out for its application in aquaculture. In the experiments, enhancement with or without artificial reef model,the effect of five reef models of different shape but the same material, and two different material reef models of the same shape were compared. The results showed that the difference of mean attractive rate (MAR) of all artificial reef models were significant (P<0.01) compared with non-reef models. The MAR of the pipe shaped reef model was the highest and the difference is significant (P<0.05) compared with the other four shaped reef models. MAR of two different materials of reef models in triangular shape was not significant (P>0.05) and the MAR of the reef made of concrete was higher than that made of marble. It is suggested that stones can also have attractive effects on Apostichopus japonicas.
