Ghana Dolphin Hunting Crisis: Causes, Laws & Conservation

Dolphins, intelligent and sociable marine mammals, face significant threats globally, with about a third of the 40 known species endangered. In West Africa, particularly Ghana, illegal hunting leads to the death of nearly 10,000 dolphins annually. This practice is driven by various factors, including their use as food and bait, and is exacerbated by declining fish stocks and poverty.

The Situation in Ghana

German biologist and dolphin expert Zandra Alte from the environmental organization Pro Wildlife highlights Ghana as a major global hotspot for dolphin hunting. Her work focuses on understanding the primary reasons behind this activity. Along the Ghanaian coast, particularly around Dicks Cove, dolphin meat is discreetly sold despite legal protections. Vendors are wary of authorities but some, like a fisher encountered, store dolphin catches in freezers, selling them for around €50 each. These are often pantropical spotted dolphins, a species considered abundant globally but facing local declines due to hunting.

Biologist Isaac Okiieri, who has researched dolphins in Ghana for years, monitors their numbers at sea. He notes that Ghanaian waters host about 18 species of dolphins and whales, with the Stanella and climbing dolphins being the most common. During an expedition 20 km offshore, a large group of pantropical spotted dolphins was observed. While these dolphins are sociable and inquisitive, their global abundance can be misleading; smaller groups often congregate temporarily, making it difficult to assess their true population size from such sightings alone. However, their numbers are shrinking in hunted areas.

Fishers admit to catching dolphins, identifying different species based on meat quality (e.g., "soft and tasty" versus "hard"). This practice is widespread, contributing to the decline of dolphin populations. Pantropical spotted dolphins are particularly vulnerable because their global population figures mask local declines, especially for resident coastal populations that are more easily targeted.

Legal Frameworks and International Challenges

Ghana has enacted the Wildlife Resources Management Act in 2024, which legally protects all dolphins and other wild animals from being caught, killed, or kept. However, enforcement remains a challenge due to the lucrative nature of illegal hunting.

Internationally, the situation is more complex. The International Whaling Commission (IWC), established to protect whales and regulate hunting, does not explicitly protect all toothed whales, including dolphins. The IWC's founding convention in 1946 did not define "whale," leading to debates among member states about its jurisdiction over smaller cetaceans. Isabelle Aila, a scientist at the Institute of Terrestrial and Aquatic Wildlife Research in Busam, emphasizes the need for the IWC to implement bans and catch quotas for dolphins, recognizing their crucial role in marine ecosystems, including nutrient circulation, fish stock regulation, and maintaining natural equilibrium.

Conservation Efforts and Community Engagement

In Senegal, US scientist Lucy Keith Jin, through her African Aquatic Conservation Fund, focuses on raising public awareness rather than solely relying on bans. Her program targets schools in fishing villages, educating children about the importance of protecting rare dolphins, particularly the critically endangered Atlantic humpback dolphin. With fewer than 3,000 individuals remaining, the goal is to sensitize children, who are more receptive to change than adults, to conservation needs. A playful approach, including theatrical performances, is used to convey the message that dolphins are valuable living creatures, not just food.

The Economic Drivers of Dolphin Hunting

Back in Ghana, the economic realities faced by fishing communities drive the continued hunting of dolphins. Zandra Alte's research indicates that dolphin meat is often used as bait to catch more lucrative prey, such as sharks, making it difficult to track the true extent of dolphin killings. Sharks themselves are also illegally caught, with their fins exported to Asia for high prices, despite some species being internationally protected.

Fishers often lack knowledge about the species they catch, complicating conservation efforts. The decline in fish stocks, partly due to industrial fishing fleets (many operating under false flags and primarily Chinese-owned), exacerbates the problem. These large trawlers, despite officially catching less than traditional Ghanaian boats, are believed to have a much higher actual catch due to illegal activities, severely impacting local fish populations. This has led to a significant drop in income for West African fishers, forcing them to seek alternative sources of food and income, including dolphins.

Poverty is a major factor; average incomes are less than €200 a month, and dolphin meat provides a welcome source of food or bait. Fishers openly admit to catching dolphins regularly, not just for bait but also to feed their families.

Data Collection and Future Solutions

Isaac Okiieri and his team use a dedicated app to systematically record data on dolphin catches along Ghana's coastline, including species, size, location, and cause of death. This data, analyzed at the University of Cape Coast, reveals that more dolphins are being caught than previously thought and helps identify hotspots for illegal activity. Similar conclusions are drawn by researchers like Isabella Vila, who attributes declining dolphin numbers to hunting, accidental entanglement in nets, and pollution.

In Senegal's Saloum Delta, conservationists conduct annual censuses of the Atlantic humpback dolphin population. Researchers use sound traps to detect dolphin vocalizations and clicks, and photographic identification of dorsal fins to track individuals. While the national park offers some protection, researchers are considering extreme measures, such as creating "insurance colonies" by blocking off mangrove channels, to safeguard the species' future.

The Path Forward

The challenges are immense. While marine ecotourism is a potential alternative livelihood, it requires significant investment and a shift away from age-old traditions. As long as foreign fishing fleets exploit the seas and local communities struggle for subsistence, dolphins will remain vulnerable. Enforcing existing laws, providing alternative income sources, and addressing the root causes of overfishing are crucial steps to protect these intelligent creatures and ensure the health of the ocean.
