Gambia’s oyster fishery is an ecological system, a women’s livelihood and a governance system at the same time
WHAT THE EVIDENCE SAYS
A qualitative case study interviewed 60 female oyster harvesters and conducted two focus groups across an urban and rural harvesting system. Participants described detailed ecological knowledge of tides, seasons, oyster availability and mangrove condition, mostly transmitted through families. They also reported increasing harvesting pressure and declining oyster abundance alongside growing use of seasonal closures, restrictions and collective monitoring as commercialization expanded.
WHY IT MATTERS / OUR READ
The study is useful because it treats ecological condition, knowledge, markets and institutions as one system rather than separate problems. For conservation practice, stronger rules without attention to women’s livelihood strategies, local knowledge and market access can miss the mechanisms that actually determine harvesting behavior.
CAVEATS / UNCERTAINTY
Declining oyster abundance is participant-reported rather than an independent ecological abundance trend, and the evidence comes from two sites and a qualitative sample. The findings support social-ecological interpretation, not a basin-wide estimate of stock condition or governance effectiveness.

Interviews with 60 female oyster harvesters show how tidal knowledge, family-transmitted practice, commercialization and formal closures are interacting inside two mangrove–oyster social-ecological systems.
