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.
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.
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.
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.
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 shad (Tenualosa ilisha), is a biologically, nutritionally, economically, socially and culturally important species in the Bay of Bengal and Persian Gulf regions, but Bangladesh enjoys the major share wherein it contributes about 517,000 tons/year. However, this important fishery declined in the late 1990’s that led the Government to formulate the Hilsa Fishery Management Action Plan (HFMAP) and started its implementation from 2005. Since then, hilsa production increased @5%/year till 2015.
The migration of anadromous fish in heterogenic environments unceasingly imposes a selective pressure that results in genetic variation for local adaptation. However, discrimination of anadromous fish populations by fine-scale local adaptation is challenging because of their high rate of gene flow, highly connected divergent population, and large population size. Recent advances in next-generation sequencing (NGS) have expanded the prospects of defining the weakly structured population of anadromous fish.
Small-scale fisheries (SSFs) have been playing a crucial role in meeting the basic needs of millions of people around the world. Despite this, the sustainability of global fisheries is a growing concern, and the factors enabling or constraining the sustainable management of small-scale fisheries remain poorly understood. Hilsa shad (Tenualosa ilisha) is the single most valuable species harvested in Bangladesh waters, serves nutrition, income, and employment to the large population.
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.
