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.
The Darwin-Hilsa project is developing an incentivebased system of hilsa fisheries management in Myanmar’s Ayeyarwady Delta. This study uses a mixed-methods approach to assess the socioeconomic status of local fishing households. Many are extremely vulnerable, owing to the seasonal nature of fishing and unpredictable flows of income. Coping strategies include informal loans, livelihood diversification, and migration, while many flout fishing restrictions to cover costs and repay loans.
The hilsa is a critically important species for smallscale fishing communities in Myanmar’s Ayeyarwady Delta and Rakhine State. Yet current fishing regulations are inadequate and exploitation rates are well beyond sustainable levels. This study analyses key parameters underlying hilsa biology, comparing them across different ecological zones of the hilsa’s range in Myanmar and across time. It provides evidence of major spawning activity between July and September in the freshwater zone, particularly in September.
The 27th “National Fish Week-2019 is being observed across Bangladesh 18-24 July 2019. This special week entirely dedicated to fish is an existing opportunity to raise awareness and encourage individuals and fish farming communities to practice sustainable fish farming, better-manage natural resources while helping prevent the extinction of various species of indigenous fish.
In the present study, digital imaging was used to measure length-frequency data from all major migratory habitats of Hilsa. This investigation appears to be the first to generate information using this technique regarding population dynamics and stock status of Hilsa, and subsequently, a guideline for using this method was developed. This is also the first time that the spatial and temporal size composition of Hilsa in sanctuary, nonsanctuary, and marine habitats were also compared.
This study was conducted to understand the mouth development during different larval stages of T. ilisha, which might assist in their aquaculture such as choosing the most appropriate live food.
This paper describes the current marine fisheries situation in the northeast sector of the Bay of Bengal, ninety percent of which corresponds to Myanmar's EEZ and ten percent to Bangladesh. With the exception of the research carried out by the fisheries research vessel Fridtjof Nansen, the Myanmar sector is largely data deficient due to political reasons.
The present study was undertaken to determine the influence of season, habitat sanctuaries, gear and physico-chemical features on the catches of hilsa shad in Bangladesh waters.
