红螯螯虾体表附生切头涡虫类研究概述

Overview of Studies on the Temnocephalans Attached to the Body Surface of Red Claw Crayfish Cherax quadricarinatus

随着红螯螯虾(Cherax quadricarinatus)养殖业的发展,附着于红螯螯虾体表的切头涡虫及其危害已引起养殖业者的广泛关注。本文介绍了切头涡虫的分类地位和分布,详细描述了切头涡虫外部形态和内部构造,并对切头涡虫的共生特性、食性、生活史、运动方式等生物学特点进行了概述,对切头涡虫的危害和防治进行了总结和讨论。本综述可为红螯螯虾的养殖、切头涡虫病的了解与防治以及相关研究提供参考。

With the development of the red claw crayfish(Cherax quadricarinatus) aquaculture industry, Temnocephalans attached to the body surface of red claw crayfish and their hazards have attracted the attention of the industry. In this paper, the taxonomic status and distribution of Temnocephalans were summarized based on literatures. Then, their external morphology and internal structures were presented in detail. Additionally, their biological characteristics of symbiosis, feeding habits, life history and movement mode were described, and their harm to crayfish and their control measures were discussed. This review is considered to provide a reference for the red claw crayfish aquaculture, and to understand temnocephalans, their prevention and control.
