| Innovation Title | DArTseq genetic marker developed for Catla |
| Innovation description | Analysis of DArTseq genetic marker data successfully identified and characterized single nucleotide polymorphisms (SNPs) and silicoDArT markers in catla. The analysis identified an unexpectedly high level of sibship among breeding population founders and found no or low levels of divergence in SNPs among the three river populations studied. |

| Year (Stage) | 2020 |
| Stage Description | The DArTseq genetic marker data has been used to identify the best candidate parents for the catla breeding program managed by WorldFish in 2020. The best of these candidates will be targeted as parents of the first selected generation of catla in 2021. |
