  深圳XXXXXL196_may18_FT特区报惠州10月27日电(记者XXXXXL196_may18_FT 陈海峰 通讯员 黄少卿 叶衍达)今年4月,科研人员在惠州市惠东县西枝江流域发现一种未被描述的马口鱼新种。近日,该研究成果在国际学术期刊《多样性》(Diversity)刊发。基于形态学与分子系统生物学研究结果,该鱼类被确认为新物种,命名为“Opsariichthys rubriventris”,拉丁文直译为“红腹马口鱼”,论文建议其中文名为“广东马口鱼”。

  据悉,该科研工作是在华南师范大学副研究员王俊杰主持的“中国-东盟渔业资源保护与开发利用”项目资助下开展的。科研人员来自华南师范大学、浙江省森林资源监测中心与西子江生态保育中心。

  该论文第一作者,华南师范大学水产学专业研究生陈嘉博、动物学专业研究生李颖滔介绍,“广东马口鱼”是一种栖息于溪流上游的鱼类,该新物种背鳍前鳞13-14片;下颌略长于上颌;成鱼颊部有两行珠星;成年雄鱼下颌、腹部、胸鳍和臀鳍前缘呈橙红色,通过以上形态特征可与同属其他物种相区分。

  论文作者之一,浙江省森林资源监测中心生物多样性监测所工程师,IUCN-ChSSG(世界自然保护联盟中国物种专家委员会)专家组委员周佳俊表示,“广东马口鱼”仅栖息于广东省内珠江流域的一些支流上游中,对栖息地环境要求高,分布范围狭窄,种群数量相对于其他马口鱼较少。由于其色彩艳丽,观赏价值高,容易成为观赏鱼贸易下的捕捞对象,亟须关注与保护。本次对该新物种的描述,对于了解马口鱼类的演化和珠江溪流鱼类多样性的保护有重要意义。(深圳特区报)
