Of 612 Mediterranean Killifish caught in the Gulf of Gabès, Tunisia, 54 (8.8%) had deformed spines, and were 8 times more likely to be deformed when from polluted areas. Deformities occurred less frequently as size increased, more often in fish under 25mm long.

Location: GCLME, West Africa

The Guinea Current Large Marine Ecosystem (GCLME) is polluted, degraded, and has declining fish stocks, but most countries in the GCLME rely on its natural resources. Local marine fishery, offshore oil production, periwinkle* harvesting and mining have an estimated value of US$49,941.4 million, of which offshore oil production accounts for 59.79%.

*Periwinkle – Catharanthus roseus G. Don (used to make the chemotherapy drug Vinblastine Sulfate)
