For decades, women in fishing communities along Lake Victoria were expected to stay on shore, selling fish rather than catching them. In Kagwel village in Kenya’s Kisumu County, stepping into a fishing boat was seen not only as unusual but as a violation of deeply rooted social beliefs.

That changed in 2002 when Rhoda Ongoche Akech, then a 39-year-old mother of seven, decided to enter the lake herself.At the time, Akech had spent years working as a fishmonger, buying fish from male fishermen and reselling them in local markets.

But rising costs for fish purchases, cooking oil, firewood and transport were reducing her earnings and making it harder to support her family.“People were alleging that when women go into the waters accompanied by men, they would engage in sexual intercourse,” Akech, now 61. She said community members initially treated her decision with suspicion, but after realising she was determined to learn fishing rather than challenge morality, opposition gradually faded.

Her decision followed an encounter in 2001 when women from neighbouring Homabay County came to Kagwel and began fishing. Watching them convinced her that the work was possible despite local resistance.“I sought the help of two young men by then to assist me with fishing as I learned,” she said.The cultural restrictions around women fishing in Lake Victoria communities are rooted in longstanding beliefs tied to gender and ritual purity.

According to Kagwel village elder William Okedo, one of the strongest taboos concerned menstruation.“It was believed that if women went into the lake while on period, they would scare away the fish and that would cause losses to people who are fishing,” Okedo said.The restrictions extended to men as well. Fishermen were traditionally discouraged from having sexual relations with their wives the night before fishing trips, based on beliefs that it would reduce their catch.

For 16 years, Akech remained the only woman fishing regularly in Kagwel, working alone among male crews.It was not until 2018 that another woman joined her. Faith Awuor Ang’awo, a 37-year-old mother of four, had also been working as a fishmonger and was facing similar financial strain.“My husband refused the idea at first,” Ang’awo said, citing fears of social backlash from the fishing community.

“But later on allowed me to join Rhoda.”In 2020, Dorcas Awiyo, then a 22-year-old mother of three, followed. Her husband, himself a fisherman, initially opposed the decision but later agreed after the family’s need for additional income became more urgent.“At first, my husband was not receptive to the idea, but later on allowed me,” she said.By 2022, when Janet Ndweyi joined the group, resistance had largely disappeared.

“I didn’t face any challenge or receive any warning when joining them because the community around was used to seeing Rhoda and Faith fishing,” Ndweyi said.Without a husband to support her and with fish trading becoming less profitable, fishing offered her a more stable income. She now uses her earnings to pay college fees for both of her children.

“Through fishing, I am able to cater for my household’s basic needs and also pay for children’s school fees that are in college,” she said.Economic necessity has been the strongest force behind the social shift.According to Wilson Onjolo, fisheries officer for Seme subcounty, boat owners at Kagwel Beach can earn between 6,000 and 8,000 Kenyan shillings ($46 to $62) on productive days. Crew members earn between 500 and 800 shillings ($3.88 to $6.20), while traders such as fishmongers may earn up to 1,000 shillings ($7.75).

That compares favourably with the roughly 500 shillings women like Akech earned daily when they relied solely on fish trading.Village elder Okedo said the economic pressure facing households has made communities more willing to reconsider long-held norms.“This is all because of economic hardships that the community is facing; it is pushing women to break the taboo,” he said.

Fisherman Dalmas Onyango said most male fishermen now support women entering the trade.“The majority of my fellow fishermen now support their decision to fish,” he said, adding that changing economic realities have made old restrictions less practical.At the same time, the lake itself is becoming less reliable.

Lake Victoria, which supports more than 42 million people for food, employment and drinking water, is under increasing pressure from overfishing, pollution, invasive species and climate change. Annual harvests remain around one million tonnes, but per capita catch rates have declined significantly.Akech said she has seen the change directly over the past two decades.

The amount of fish she catches today is noticeably lower than when she first entered the lake in 2002.Chris Mutai, senior meteorologist in charge of the Kisumu meteorological station, said rising water temperatures are contributing to the decline by encouraging algae growth and reducing oxygen levels in the lake.

“To reverse this, people should keep off riparian land to allow undergrowth that will serve as the breeding ground of fish, and avoid pollution of the lake that traps more heat than plain, clear water,” Mutai said.He warned that temperatures could rise by another 0.5 degrees Celsius over the next 10 to 20 years, reaching between 29.5C and 31C.

Without stronger environmental controls, including protection of riparian zones and regulated fishing, fish stocks are expected to continue falling.Weather forecasting has become increasingly important for fishing communities. Mutai’s office distributes five-day forecasts through WhatsApp groups and local government channels, helping fishermen and fisherwomen prepare for dangerous lake conditions.

Despite their success, Akech and her team still operate in a legal grey area.Susan Claire, acting director of fisheries and blue economy for Kisumu County, said women officially participate as boat owners and fish traders, but not as night fishermen or crew members.“We have women who own boats and women traders, but they are not involved in night fishing or as boat crew members,” Claire told Al Jazeera.

That leaves women like Akech without formal recognition or equal access to support available to male fishermen.However, Christopher Aura of the Kenya Marine and Fisheries Research Institute said in 2023 that Lake Victoria had more than 47,000 fishermen, including 1,000 women, suggesting official county records may not fully reflect women’s participation.

Claire acknowledged that declining fish stocks remain a major concern and said the county is working with meteorological services and Beach Management Units to improve awareness, climate adaptation and enforcement against illegal fishing.For Akech, the debate is less about recognition than survival.She continues to leave before dawn with the same determination that first took her to the water more than two decades ago.

Some days the catch is poor, and the income barely covers the effort. On better days, it is enough to keep going.The lake has changed, but so has the community around it.

Fisherman Ibrahima Mar, 55, said dwindling catches have upended a way of life sustained for generations in Rufisque, near Dakar. He described a steady depletion of fish stocks that has left traditional fishers struggling to survive. “The fish have been taken from our path,” he said, pointing to worsening conditions in recent years.

Analysts attribute the decline to a combination of illegal practices and large-scale industrial operations. Bassirou Diarra, Senegal country manager for the Environmental Justice Foundation, said vessels engaged in bottom trawling and other activities often operate under Senegalese flags but are linked to foreign ownership, including European and Asian interests.

“These practices not only reduce fish availability for local consumption but also limit economic returns to the country,” Diarra said, citing issues such as unauthorized fishing in protected areas, non-compliant equipment and lax licensing.

A 2025 report by the Environmental Justice Foundation estimated that 57% of exploited fish populations in Senegal are in a state of collapse, underscoring the scale of the crisis.

The decline has had ripple effects across coastal economies. According to census data, more than 82,000 people in Senegal depend on fishing, accounting for about 2% of the workforce. Ancillary sectors such as fish processing, transport and retail have also been affected.

Local fishing leaders say productivity has sharply declined. Mamadou Diouf Sene, head of the Rufisque Fishing Wharf Revenue Commission, said it now takes up to seven months to catch what previously required two months, reflecting the strain on marine resources.

The economic pressure has contributed to increased migration attempts, with some fishermen undertaking dangerous journeys to Europe in traditional wooden boats known as pirogues. Community members say these journeys often end in tragedy.

Environmental factors have compounded the problem. Researchers note that climate change is shifting small pelagic species, such as sardinella and horse mackerel, northward, further reducing local availability.

Authorities acknowledge enforcement challenges. Cheikh Salla Ndiaye of Senegal’s Directorate of Fisheries Protection and Surveillance said monitoring vast maritime areas remains difficult despite support from security forces.

Efforts to improve oversight are underway, with environmental groups such as Greenpeace introducing technologies including satellite tracking and mobile reporting tools to help identify illegal activity at sea.

The crisis has raised concerns about long-term food security and economic stability in Senegal, where fish remains a central component of both diet and cultural identity.

The analysis, led by Dr. Zeb Hogan of the University of Nevada, evaluated data on more than 15,000 freshwater species and identified a significant collapse in migratory populations across major river systems.

The report highlights that these migrations, which rank among the largest animal movements globally, are increasingly disrupted. Species such as the dorado catfish, which travels an estimated 11,000 kilometres between the Andes foothills and the Amazon estuary, exemplify the scale of these journeys.

More widely known migratory species, including salmon and eels, are also affected.

According to the CMS assessment, freshwater ecosystems are particularly vulnerable to human activity. Pollution entering rivers and lakes, the construction of dams that obstruct migration routes, and overfishing have collectively reduced fish populations.

Rising water temperatures linked to climate change are compounding these pressures.Amy Fraenkel, executive secretary of CMS, stated that migratory species face increasing challenges throughout their life cycles, often crossing multiple national boundaries.

The report underscores that coordinated international action is necessary to address these pressures, particularly as river systems frequently span more than one country.

Migratory freshwater fish support some of the world’s largest inland fisheries and are a critical source of food and livelihoods for hundreds of millions of people. In Cambodia’s Tonlé Sap lake, part of the Mekong river system, more than 100 migratory species contribute to high-yield fisheries, with catches reaching several tonnes within short periods, according to Hogan.

The report identifies 325 freshwater fish species that cross international borders and could qualify for enhanced protection under CMS frameworks. However, only 24 species are currently listed, many of them sturgeon historically targeted for caviar production.

Delegates from 132 CMS member states are meeting in Brazil, where improving river connectivity and protecting migratory pathways form a central part of discussions.

Proposed measures include removing or preventing barriers such as dams, maintaining adequate water flows, reducing pollution, and coordinating fisheries management across borders.

The Amazon basin remains one of the last relatively intact strongholds for migratory freshwater fish. Regional initiatives, including a proposed decade-long conservation plan for migratory catfish, are being considered as potential models for other river systems.

The Mekong basin is identified as a region of acute concern, with large migratory species facing heightened extinction risks due to overfishing and habitat disruption. Key countries in the basin, including Thailand, Cambodia, Laos and Vietnam, are not currently part of the CMS treaty framework.

Other priority basins highlighted in the assessment include the Danube, Nile and Ganges-Brahmaputra systems.

The report also notes past losses, including the extinction of the Chinese paddlefish in the Yangtze River, attributed to habitat disruption following the construction of the Gezhouba dam in 1981.
