Migration of an anadromous fish to heterogeneous environment continuously enforces a selective pressure that incorporates a wide range of life-history strategies by which individuals adapt to the prevailing conditions.
National fish hilsa was declining in Bangladesh. The government of Bangladesh took several measures like the establishment of sanctuaries, bans on catching of brood hilsa and its offspring jatka, and reduced the illegal gears. USAID/ECOFISH-Bangladesh project joints hand with the coastal fishing communities and stakeholders by establishing an adaptive fisheries co-management in hilsa shad sanctuaries as one of the key strategies to revitalize the once-degraded stock of hilsa shad in the Padma-Meghna riverine-coastal habitats.
Hilsa: Status of Fishery and Potential for Aquaculture is a proceedings book, which is edited by an international team of experts and authored by 10 international expert teams working on different disciplines of the hilsa shad. Hilsa is a widely distributed fish within the Bay of Bengal region and harvested in the waters of Bangladesh, India and Myanmar. It is famous worldwide for its delicious taste and superb texture, which persist for a long time. Hilsa is unique in that it contains high amounts of both proteins and lipids.
The anadromous Hilsa shad (Tenualosa ilisha) live in the Bay of Bengal and migrate to the estuaries and freshwater rivers for spawning and nursing of the juveniles. This has led to two pertinent questions: (i) do all Hilsa shad that migrate from marine to freshwater rivers come from the same population? and (ii) is there any relationship between adults and juveniles of a particular habitat? To unravel the answers of the above two questions, the present study was conducted by identifying a set of neutral and adaptive genetic markers.
