摘要

于2010年11月至2011年4月, 在福建平海湾海域开展了污损生物附着对杂交鲍Haliotis discus hannai生长和存活的影响研究。结果显示, 鲍壳上污损生物种类主要是网纹藤壶Balanus reticulatus、三角藤壶B. trigonus、褶牡蛎Alectryonella plicatula和翡翠贻贝Perna viridis, 具有明显的热带、亚热带海域污损生物群落特点。对照组与去污处理组之间成活率无显著性差异, 去污作业短期内会对鲍类生长产生负面影响。壳缘部位被生物附着污损的鲍类, 其生长率有所降低, 这可能与壳缘处附着的污损生物会堵塞鲍鱼呼吸孔有关, 妨碍其呼吸和排泄等代谢活动正常进行。

Abstract

The effects of shell fouling on the growth and survival of the abalone Haliotis discus hannai from November 2010 to April 2011 in the Pinghai Bay, Fujiang province was studied. A total of six groups were prepared, one control and five treatments (umbo region fouled, ventral edge fouled, umbo region fouling removed, ventral edge fouling removed and shell fouling removed). The results showed that the major fouling species colonizing on the abalone shell were acorn barnacles Balanus reticulatus and B. trigonus, oyster Alectryonella plicatula and mussel Perna viridis. On the survival rate of the abalone, there was no significant difference between the control and treatment groups. A negative effect on the shell length growth was observed after fouling was removed for 50 days. The growth rates including shell length and weight of the abalone with the ventral edge fouled were lower than those with fouling removed, which may be due to the fact that the open respiratory pores near the shell's outer edge were covered by fouling organisms and the normal respiratory process was hindered.
