1. Introduction: The Global Significance of Fish and Its Economic Role
Fish is far more than a dietary staple—it is a foundational pillar of global trade, employment, and economic resilience. From small-scale coastal fisheries to massive industrial processing plants, the seafood supply chain touches hundreds of millions of lives, yet its true economic footprint remains obscured. Behind every fillet on a supermarket shelf lies a complex web of labor migration, informal work, and systemic cost pressures that shape markets worldwide. Understanding this hidden labor is key to grasping fish trade’s real economic impact.
Labor Migration: The Engine Behind Fishing Hubs and Processing Centers
Fish trade depends heavily on mobile labor, driven by geographic and seasonal patterns. In Southeast Asia, millions migrate annually from rural fishing villages to coastal processing zones in Thailand, Vietnam, and Indonesia, seeking better wages. Similarly, Peru’s anchovy fleet draws workers from Andean highlands, while Norway’s salmon industry relies on cross-border expertise from the Baltic states and beyond. These flows transform local economies—stimulating demand for housing, transport, and services—yet migrants often remain economically invisible, locked into temporary contracts with limited social protections.
- Migrant labor sustains 70% of seasonal fishing operations in Southeast Asia, according to FAO data.
- Processing hubs in Thailand’s southern provinces employ over 300,000 workers, 85% of whom are foreign or temporary, creating informal labor pools that drive down costs.
- This mobility fuels economic interdependence but deepens vulnerability, as workers’ legal status often blocks access to fair wages or healthcare.
Gendered Labor in Post-Harvest Processing: Hidden Contributions and Economic Marginalization
While fishing draws men and women from diverse regions, post-harvest labor remains sharply gendered. In cold storage facilities and fish markets across India, Bangladesh, and West Africa, women constitute the majority of workers—yet occupy the lowest-paid, most precarious roles. They perform repetitive tasks such as cleaning, sorting, and packaging, often without formal contracts or benefits.
- Women in Bangladesh’s fish processing zones earn 40% less than male counterparts for identical work.
- Despite making up 60% of informal labor, only 12% hold managerial positions or union representation.
- This marginalization suppresses household incomes and limits economic upward mobility, reinforcing cycles of poverty.

Informal Employment: Sustaining Low-Cost Global Fish Supply Chains
A defining feature of fish trade is its reliance on informal employment—contracts without legal registration, safety oversight, or social security. Across Latin America, Africa, and South Asia, up to 90% of fish processing and distribution jobs operate off-the-books, enabling traders to minimize costs and maximize margins.
| Formal vs. Informal Employment in Fish Trade |

| % of workers in informal roles |
| 90% |
| Average monthly earnings (global average) |
| $400–$800 |
| Annual economic loss from informal labor (estimated by ILO) |
| $12 billion |
These informal structures allow global retailers to maintain low consumer prices, but at the cost of labor rights and long-term supply chain stability. When workers lack protections, outbreaks of illness, disputes, or strikes disrupt operations—threatening food security and trade flows.

Labor Migration Patterns Shaping Fishing Hubs and Processing Zones
Global fish trade flows are deeply shaped by labor migration, creating dynamic hubs where supply and demand converge. Coastal nations like Indonesia and Senegal export raw catches to processing centers in Thailand, Spain, and the Netherlands—destinations drawn by both infrastructure and migrant workforces.
- Migrant workers from Myanmar and the Philippines fuel Thailand’s seafood processing, often settling in segregated worker villages near ports.
- In Senegal, seasonal labor from Mali and Guinea supports the country’s booming frozen fish export sector, peaking during Atlantic fishing seasons.
- This mobility enables year-round production but embeds workers in transient, high-risk environments.
Gendered Roles in Post-Harvest Labor and Economic Marginalization
Post-harvest operations reflect entrenched gender disparities. While men dominate logistics and equipment handling, women dominate low-wage, repetitive tasks like deboning, filleting, and packaging—roles rarely recognized or compensated fairly.
- Glassdoor data (2023): Women in Indian fish processing earn 38% less than men for equivalent hours.
- ILO report: Only 11% of women in West African cold storage facilities hold formal contracts.
- UNDP analysis: Female workers are 2.3 times more likely to face verbal abuse and harassment without legal recourse.

Informal Employment: Sustaining Low-Cost Global Supply Chains
The backbone of fish trade’s affordability lies in informal labor—unregistered, informal contracts, and off-the-books employment. Across Latin America, Africa, and South Asia, up to 90% of fish processing and distribution operate informally, enabling traders to undercut costs and maximize margins.
| Formal vs. Informal Employment in Fish Trade |
|---|
| % of workers in informal roles |
| 90% |
| Average monthly earnings (global average) |
| $400–$800 |
| Annual economic loss from informal labor (estimated by ILO) |
| $12 billion |
| Number of workers in informal fish trade (ILO estimate) |
| Over 60 million |
This informal ecosystem fuels low prices for consumers but suppresses labor rights, weakens public health oversight, and undermines long-term supply chain resilience. Workers lack safety nets, reducing their ability to respond to trade shocks like disease outbreaks or climate disruptions.
