摘要

hildebrandi是墨西哥西南部特有的一种小型(<130毫米)淡水鱼,因栖息地丧失和入侵而被列为濒危物种。我们确定并比较了当地鳉鱼(T. hildebrandi)不同种群的长度-重量关系、相对重量和条件因子参数。对墨西哥恰帕斯高原3个鳉鱼种群在整个分布范围内的富尔顿条件因子(K)、相对重量(Wr)和长重关系进行了估算。在人为活动较多的鱼类中,Wr显著最低。本文首次在科学文献和Fishbase等数据库中公布了T. hildebrandi的体细胞指标和长权关系。

Evaluation of somatic indexes in the endangered and endemic killifish Tlaloc hildebrandi (Cyprinodontiformes: profundulidae)
ABSTRACT Tlaloc hildebrandi is a small (<130 mm) freshwater fish endemic to Southwest Mexico and is listed as endangered through habitat loss and invasive species. We determine and compare the parameters of the length–weight relationship, relative weight, and condition factor among different populations of the endemic killifish, T. hildebrandi. Fulton’s condition factor (K), relative weight (Wr), and the length–weight relationship were estimated for three killifish populations throughout its distribution range in the highlands of Chiapas, México. The Wr was significantly lowest in fishes where there are higher anthropogenic activities. The somatic indexes and the length–weight relationships for T. hildebrandi are hereby published for the first time in both the scientific literature and databases, such as Fishbase.
