Background: The Deccan mahseer, Tor khudree (Sykes, 1839) is a potential game and food fish species belonging to the family cyprinidae and is categorized as endangered. Its distribution is restricted to southern part of India, specifically to Peninsular Rivers. This study is first to assess the genetic diversity and differentiation in Tor khudree by developing novel simple sequence repeat (SSR) markers.

Article Synopsis
- The Deccan mahseer (Tor khudree) is an endangered fish species in peninsular India, threatened by overfishing and habitat loss, necessitating a conservation program.
- Researchers studied 152 samples from four rivers, identifying high genetic diversity with 44 distinct haplotypes from two mitochondrial genes.
- Most genetic variation (71.02%) occurred within populations, with significant differentiation between population pairs, indicating the need for tailored conservation efforts.
Article Synopsis
- Spermatogenesis is a complex process, and this study focuses on the in vitro propagation of spermatogonial stem cells (SSCs) from catfish (Clarias batrachus) to better understand their biology.
- Researchers used collagenase and techniques like Ficoll gradient centrifugation and magnetic sorting to purify SSCs, yielding around 3 million cells for further study.
- After over two months of culturing in a specific medium, the stem cells showed typical characteristics and were able to differentiate into spermatids, with a small percentage capable of fertilizing, which may facilitate further research in both basic and applied biology.
