Tidal river fishermen have decimated the mangrove forest cover around the Densu Delta for traditional fish traps — with only around 16 red mangrove trees left standing. Mangrove biomass is critical for mangrove fish assemblages, which the fishers depend on. This habitat degradation has led to a loss of biodiversity in the area — leading to a decline in fish stock in the Densu intertidal zone. The video below explores this problem with some amazing aerial landscape views.Read More
In a classic Tragedy of The Commons scenario, industrial fishing vessels are dredging up small pelagics reserved for the artisanal sector in Ghana, having already depleted higher trophic species. They tip overboard the unwanted. In response, the canoe fishers are resorting to destructive fishing methods, including using bombs to send a shock wave through the water to maximize their catch and light to attract shoals of fish. The artisanal fishers say they will only stop when the Government stops the trawlers. Climate change is magnifying these vulnerabilities to the extent that fishermen in villages do not go to sea because 'there is no fish in the ocean'. Is the future already here?
Fish processors in Ghana trade-off between their livelihoods and exposure to cancer-causing toxicants such as PAHs. Climate-related shocks, overfishing, and other human activities are also shaping the mobility of migrant fishers.
