Fisheries co-management in hilsa shad sanctuaries of Bangladesh: Early experiences and implementation challenges

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 fishery management in Bangladesh

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.

Population genomics of an anadromous Hilsa Shad Tenualosa ilisha species across its diverse migratory habitats: Discrimination by fine-scale local adaptation

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.

Understanding social-ecological challenges of a small-scale hilsa (Tenualosa ilisha) fishery in Bangladesh

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

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.

Fine-scale population structure and ecotypes of anadromous Hilsa shad (Tenualosa ilisha) across complex aquatic ecosystems revealed by NextRAD genotyping

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.

Socioeconomic characteristics of hilsa fishers in the Ayeyarwady Delta, Myanmar: Opportunities and challenges

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.

Spawning seasonality of hilsa (Tenualosa ilisha) in Myanmar's Ayeyarwady Delta

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.

National Fish Week Bangladesh 2019

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.
