Factors Contributing to the Decline of Guitarfish in Ghana

The decline of guitarfish, locally known as "esene," along Ghana's Atlantic coast is attributed to a combination of factors, primarily driven by unsustainable fishing practices and demand from international markets. Their critically endangered status, red-listed by the IUCN, reflects a severe population collapse not only in Ghana but across West Africa, where related species like sawfish and wedgefish are also becoming increasingly scarce.
Unsustainable Fishing Methods and Local Demand

Destructive fishing practices are a significant contributor to the dwindling guitarfish populations. The use of lights at sea, a method employed to attract fish, is specifically cited as a major factor in depleting stocks. Furthermore, the meat of the guitarfish is a local delicacy, creating a consistent demand that incentivizes its capture. This local consumption, coupled with the value of their fins in international markets, places immense pressure on the species.
International Market Demand for Fins

Beyond local consumption, the fins of guitarfish are highly sought after in international markets, particularly in China, where they are used in shark-fin soup. This global demand creates an additional economic incentive for fishermen to catch these already vulnerable fish, making conservation efforts more challenging. The lucrative nature of the international fin trade exacerbates the depletion of guitarfish stocks.
Broader Environmental Pressures

In addition to direct fishing pressures, guitarfish populations are also impacted by broader environmental changes. Pollution in the marine environment is cited as a contributing factor to their decline. Shifts in traditional fishing practices over time, potentially leading to more intensive or less selective methods, also play a role. Furthermore, the overarching threat of climate change is identified as another reason for the diminishing numbers of these critically endangered fish.
