The clariid catfish, Clarias batrachus commonly known as Magur, has declined drastically from natural habitats in India during the last decade. This fish is highly preferred fish by Indian consumers and has high market demand. As a result traders often substitute C. batrachus with a morphologically similar but supposedly banned exotic catfish, C. gariepinus, in India. This study uses rigorous morphological comparisons confirmed by DNA barcode analysis to examine the level of substitution of C. batracus by C. gariepinus in India. Our results indicate that up to 99% (in many cases) of the market samples sold as Magur or C. batrachus were in fact C. gariepinus.
胡子鲶，通常被称为麦古的印度胡子鲶，在过去十年里已从印度的自然栖息地急剧减少。这种鱼深受印度消费者喜爱，市场需求很高。因此，在印度，贸易商经常用一种形态相似但据推测被禁止的外来鲶鱼——尖吻鲈，来替代印度胡子鲶。本研究通过DNA条形码分析证实的严格形态学比较，来研究在印度尖吻鲈对印度胡子鲶的替代程度。我们的结果表明，在许多情况下，高达99%被当作麦古或印度胡子鲶出售的市场样本实际上是尖吻鲈。
