Innovation TitleGangetic Hilsa ecotypes/races and its return to natal river for spawning discovered by genetic analysis
Innovation description We applied an innovative model that uses fundamental population genomics information to inform conservation and management of Hilsa shad. This help in motivating fishers not to catch the juveniles, as they will get the assurance of getting back the juvenile as adult in the respective rivers. This innovative model that may be valuable for other aquatic species, especially in anadromous fish species that intersect diverse ecotypes during their life-history stages.
