Guitarfish Populations Critically Endangered in Ghana Due to Overfishing and Environmental Factors

Guitarfish populations along Ghana's Atlantic coast are critically endangered due to a combination of factors, primarily driven by intense fishing pressure for both local consumption and lucrative international markets, exacerbated by broader environmental changes. These species, known locally as "esene," have seen drastic declines, with related species like sawfish potentially already absent from Ghanaian waters.
High Demand Drives Unsustainable Fishing Practices

The critically endangered status of guitarfish is largely a consequence of their high value in both local and international markets. Their meat is considered a delicacy in Ghana, consumed in various soups and stews, while their fins are highly sought after in international trade, particularly in the Chinese market, where they are used in shark-fin soup. This dual demand creates significant incentives for fishermen to target guitarfish, leading to unsustainable catch levels. Traders have observed a consistent decrease in guitarfish catches over the years, a trend that older residents recall vividly, remembering a time when these fish were abundant.
Destructive Fishing Methods and Habitat Degradation Contribute to Decline

Beyond direct overfishing, destructive fishing methods are significantly depleting guitarfish stocks. The use of lights at sea, for instance, is cited as a major contributor to the depletion of fish populations, though the precise mechanisms by which this practice impacts guitarfish specifically are not detailed. Furthermore, broader environmental issues such as pollution, evolving fishing practices, and the overarching effects of climate change are identified as contributing factors to the decline of guitarfish and other marine life in Ghanaian waters.
Conservation Efforts Underway Amidst Scarcity

In response to the alarming decline, conservation efforts are being implemented, though the scarcity of guitarfish presents a significant challenge. Initiatives are underway to persuade fishermen to cease catching guitarfish by developing alternative livelihoods, such as snail farming, which has been adopted by some fishing families. Additionally, Ghana has established a 703-square-kilometre marine protected area, designated in April, which is to be co-managed by coastal communities and the government. Local fishermen, equipped with GPS trackers, have also actively mapped approximately 15 square kilometres of critical guitarfish habitat, demonstrating a growing local commitment to understanding and protecting these vital areas.
