"We know what we are, but know not what we may be."
—William Shakespeare, Hamlet
Shakespeare's timeless quote captures the paradox that defines life along the Bay of Bengal. On these shifting coasts, fishermen and salt workers understand the tides, winds, and currents with remarkable intimacy.
However, as they often say, "the sea has moods". Their generations of accumulated wisdom—mastering moon cycles, salinity fluctuations, cloud formations, sea scents, and wind directions—never offer complete certainty.
What Episode Six described as storms and survival continues here as a different form of endurance: the daily negotiation with a fluid, unpredictable environment where livelihoods rely on reading nature's signals with precision and humility.
This episode shifts the focus from cyclones and disaster preparedness to the people whose daily work makes the Bay a living partner.
The emphasis now moves to small but significant acts of livelihood—nets cast at dawn, salt pans glinting at noon, and communities shaped by centuries of environmental familiarity, KN Chaudhuri writes in "Trade and Civilisation in the Indian Ocean: An Economic History from the Rise of Islam to 1750" (1985).
These practices exemplify what scholars call vernacular maritime knowledge, a deep, embodied understanding linking ecology with culture, survival with identity.
Living with water: Fishing as ancestral knowledge
Fishing in the delta predates chronicles and kingdoms. The rivers of the Ganges, Brahmaputra, and Meghna systems have created natural corridors for movement, sustenance, and settlement. Communities in coastal and estuarine areas have built economies and social structures around fishing, establishing rituals, festivals, and myths linked to the water. For many families, fishing is not just an occupation but an inheritance.
Fisherfolk navigate the waters through "reading" rather than measuring: the tilt of a mast in the wind, the sound of waves breaking on a sandbank, the colour of the water after rainfall. These skills reflect what S Ahmed, in his book "Oral Histories of Fisherfolk in Bangladesh" (2012), calls situated ocean literacy, passed down orally, often from grandfather to grandson.
Fishermen plan their expeditions around the lunar cycle, as the moon influences the rise of the tides and the movement of hilsa and shrimp. Salinity shifts—caused by monsoon rains upstream or tidal surges from the sea—guide where and when nets should be set.
This relationship transforms the Bay from a distant space into a carefully observed and negotiated partner. The fishermen's knowledge is not theoretical; it is practical, lived, and ongoing. Himanshu Prabha Ray in "The Archaeology of Seafaring in Ancient South Asia Ray" (2003) points out that this understanding reflects techniques used by early seafaring communities across the Indian Ocean, showing centuries-old continuity in human interaction with changing coastal environments. While satellite images and digital maps now assist state agencies, local communities still rely on embodied perception of nature—a skill no algorithm can fully replicate.
Salt and the development of coastal civilisations
If fish symbolises mobility, salt signifies settlement. Salt production along Bangladesh's coast—especially in Cox's Bazar, Maheshkhali, Teknaf, and parts of Chattogram—has influenced communities and trade for centuries. Salt workers follow a demanding rhythm of evaporation, shaping fields, channelling seawater, and protecting fragile pans from rain and contamination. Under the relentless tropical sun, their labour transforms the sea into a vital resource for preservation, food security, and trade.
Historically, salt production has been closely linked to taxation, revenue collection, and colonial control. In "Salt and Coastal Economy in Bengal: Historical Perspectives" (2018), Mahbub Alam illustrates how the British Raj's salt policies shaped class structures and economic hierarchies in Bengal, connecting a seemingly local activity to global imperial governance.
The salt pans serve as a reminder that the Bay's coastal economy has never been isolated; it has always been interconnected within larger trade, control, and regulation networks. As Sanjay Subrahmanyam notes in "The Portuguese Empire in Asia, 1500–1700: A Political and Economic History" (1993), salt played a vital role in maritime trade, diplomacy, and food preservation demonstrates for the broader Indian Ocean region.
Salt workers' expertise—balancing tidal flows, evaporation rates, and climatic changes—is another form of environmental adaptation. Their collaborative labour patterns foster social networks, reciprocal arrangements, and a shared resilience. The salt fields are as much a cultural landscape as an economic one.
Livelihoods influenced by culture, memory, and the sea
The Bay influences not only what people do but also who they are. Fishing and salt-making communities maintain rich oral traditions—stories of near-death experiences, heroic rescues, peculiar catches, and the moral duties of life at sea. These stories act as cultural treasures that teach humility, cooperation, and respect for the unpredictable nature of the environment.
RK Chowdhury and M Hossain in their 2014 paper noted that such stories are often associated with warnings about storms, cyclones, and dangerous waters, integrating ecological knowledge into moral lessons. Many fishing families commence each voyage with prayers, seeking divine protection. Here, environmental uncertainty becomes a spiritual experience, reinforcing a worldview that believes human survival depends on both skill and grace.
These communities also establish collective institutions—cooperatives, informal councils, and shared risk-management systems—where decisions are made by consensus. These structures form the backbone of coastal resilience and provide insights into grassroots climate adaptation that top-down planning sometimes overlooks.
The Bay as a gateway: Trade, markets, and global connections
Fishing and salt production connect Bangladesh to regional and global commodity networks. Hilsa migrates from the Padma estuary to international markets; dried fish (shutki) reaches Sri Lanka, Myanmar, and Southeast Asia; shrimp farms supply Europe, East Asia, and the Gulf. Salt enables preservation and industrial processes, linking small coastal villages with urban centres and international industries.
In "Ecological Economics of Coastal Fisheries: Sustainability and Community Management" (1997), Pomeroy and Berkes describe fishery economies as "ecological markets"—systems where price, availability, and distribution depend not only on demand but also on environmental conditions, seasonal variability, and local knowledge.
Bangladesh's coastal economy exemplifies this interaction. Fishermen's skills in reading currents support centuries-old trading routes that once connected Bengal to Arabia, Southeast Asia, and East Africa.
In this context, the Bay serves as both a lifeline for coastal communities and an entry point into broader geopolitical currents. What Episode 7 examined through "The Bay in the Age of Exploration: Columbus, Vasco da Gama, and the World Beyond—Tides of Discovery and Empire", highlighted the Bay as a stage where global ambitions, maritime exploration, and imperial networks first clashed.
This theme recurs in Episode 8, depicting the Bay as a landscape of human resilience, environmental fragility, and economic interdependence.
Here, the focus shifts from the grand movements of empires to the daily lives of fishermen and salt workers who directly experience the Bay's promises and hazards. This human-centred narrative naturally links to Episode 9, where the frontier again transforms—this time into a contested space shaped by early colonial encounters. Through the perspectives of figures such as John Eaton and the expanding East India Company, the Bay of Bengal becomes not just a geographical region but a crucible where commerce, coercion, and cultural exchange laid the earliest colonial foundations of coastal Bengal.
Vulnerability, Adaptation, and the Emerging Uncertainties
However, the Bay's generosity is increasingly at risk. The very communities that support coastal economies face significant dangers.
· Cyclones strike with greater frequency and intensity.
· Sea-level rise erodes land and contaminates freshwater.
· Salinity intrusion reduces crop yields and complicates salt production.
· Storm surges endanger fishing expeditions.
· Temperature changes reduce fish stocks and alter marine habitats.
These threats reveal a harsh reality: the environmental balance that has supported centuries of adaptation is becoming unstable. Although Bangladesh has made significant progress in early warning systems and cyclone preparedness, many challenges related to livelihoods still persist. Unpredictable weather complicates fishing schedules; unexpected rain damages salt pans; and younger generations are increasingly seeking employment outside these traditional sectors.
Nevertheless, coastal communities continue to adapt by harnessing both indigenous knowledge and new technologies—such as GPS devices, mobile weather alerts, improved boat designs, and mechanised salt pans. These combinations of tradition and innovation exemplify Bangladesh's evolving coastal resilience (Chaudhuri 1985; Chowdhury and Hossain 2014).
Ocean Literacy, Sustainability and National Significance
The practices of fishermen and salt workers demonstrate a form of localised ocean literacy—an understanding of tides, species behaviour, monsoon cycles, and ecological balance. Such literacy is essential for sustainable resource management, ensuring that the Bay's bounty benefits both current and future generations.
At the national level, these livelihoods overlap with wider priorities.
· Food security
· Blue economy development
· Coastal stability and social cohesion
· Environmental stewardship
· Maritime sovereignty
Fishing and salt are therefore not marginal activities; they are essential parts of Bangladesh's effort to responsibly engage with the Bay as a frontier of growth, resilience, and strategic opportunity.
A bridge to Episode 9
As we transition from the lived experiences of coastal communities to the historical frontier examined in Episode 9, a significant continuity becomes clear. The places where fishermen cast their nets and salt workers farmed their lands were once the same sites where early colonial agents observed, intervened, and planned expansion. John Eaton and the East India Company viewed these coasts not only as centres of trade but also as strategic entry points—locations where local livelihood systems intersected with global imperial interests.
Understanding the lived rhythms of the Bay today clarifies how past actors perceived its value. The frontier Eaton encountered—coastal Bengal in the making of empire—was built upon the same ecological knowledge, the same human-environment relationship, and the same vulnerabilities that continue to shape the Bay's communities.
