Kenya's Mida Creek Fishers Face Shrinking Catches and Coastal Pressure as Ocean Warming Reshapes Indian Ocean Fisheries

Along the shores of Mida Creek in Watamu on Kenya's Indian Ocean coast, fishers and fishmongers are confronting a combination of declining stocks, warming waters, destructive fishing practices, and growing competition for coastal space from tourism development, with catches that once sustained generations of families now reduced to two or three kilograms per boat on many days. Community groups are responding with mangrove restoration campaigns, beach cleanups, and proposals for temporary no-fishing zones, but fishers say government support and genuine public participation in development decisions will be needed if the creek's fisheries are to survive the next decade.

 

Declining Catches and a Generation of Change

 

Philip Baya, chairperson of the Dongokundu local fisher group and a Mida Creek fisherman for more than 30 years, describes a transformation in the fishing grounds that is visible in every trip on the water. Fish that could once be caught close to shore, within sight of women waiting on the beach, now require boats to travel much farther into the creek or out toward the open sea. Catches have fallen sharply, with many returning fishers bringing undersized or juvenile fish that raise concerns about the long-term sustainability of the local fishery. Alice Kazungu, a fishmonger and vice chair of the newly formed Mida Beach Management Unit, has described waiting from early morning until midday for boats to return, sometimes watching fishers come back empty-handed. For Kazungu, who depends almost entirely on selling fish to feed her children, the wait has become a daily symbol of a deeper uncertainty that is reshaping livelihoods across the creek.

 

Ocean Warming and Environmental Drivers

 

Scientists have documented warming sea surface temperatures across parts of the Western Indian Ocean, one of the fastest-warming tropical ocean regions globally, and community members in Mida Creek describe observing warmer waters and stronger tidal currents than in previous decades. Some species that were once common in local catches have become scarce or disappeared. The broader scientific context is clear: the global ocean has absorbed more than 90 percent of the excess heat trapped by greenhouse gases, with rising temperatures driving coral bleaching, disrupting breeding cycles, and reshaping fish habitats across tropical coastal systems. An El Niño event building in the tropical Pacific is expected to affect several coastlines including the Western Indian Ocean, adding a further near-term stressor to a system already under chronic thermal pressure. Baya has also attributed part of the decline to destructive fishing practices including monofilament nets, illegal gear, and bait-digging that has damaged seagrass beds, mangroves, and nursery habitats where fish once thrived in abundance.

Coastal Development and Community Access

 

The pressures on Mida Creek's fishing communities extend beyond the water. As Watamu has grown into one of Kenya's most popular coastal destinations, tourism businesses, resorts, restaurants, and recreational boating operations have expanded along the shoreline, competing for the same coastal space that traditional fishers have relied on for generations. Many community members welcome the jobs and income that tourism provides, but fishers are increasingly concerned about proposals that could affect the landing sites used to launch, repair, and store fishing vessels. Boat operator and fisher Said Bayathoya has stated that development should not happen without community involvement, describing fishing as the only livelihood available to families who have lived along the creek for generations. Baya has called explicitly for public participation before any decisions affecting landing sites or coastal access are made, arguing that communities have a right to be included in the governance of the spaces on which their survival depends.

 

Community-Led Conservation and Restoration Efforts

 

Despite the scale of the challenges, Mida Creek's fishing communities have organised substantial self-directed responses. Community groups have launched mangrove restoration campaigns, with BMU members including Kazungu planting new trees that provide breeding grounds for fish, reduce coastal erosion, and stabilise the shoreline. The Mida Creek Conservation Community, an umbrella body coordinating dozens of local conservation groups, oversees mangrove monitoring and restoration efforts across the creek ecosystem. Fishers are also advocating for temporary no-fishing zones, or fish enclosures, that would allow populations to recover and reproduce within protected sections of the creek before those areas are reopened to fishing. Baya has argued that such protected areas could benefit both fishing communities and tourism operators by allowing fish to multiply and restoring the ecological abundance that makes both livelihoods viable, and other stakeholders have suggested that government support for offshore fishing access could reduce the concentration of effort in already-stressed nearshore habitats.
