Illegal, unreported and unregulated (IUU) fishing is posing a significant threat to Sierra Leone's fishing industry, which contributes 12% to the country's GDP and provides protein for 80% of the population. The industry, which employs 500,000 people, is under threat from foreign vessels engaging in IUU fishing, with high-value fish species like bonga, snapper and grouper particularly vulnerable. The government has made efforts to address the issue, but corruption and mismanagement have hindered progress. The country lacks detailed statistics on fish population replenishment rates and needs a comprehensive fisheries strategy. Despite some successes in apprehending illegal vessels, consistent action and enforcement of legislation are needed, along with international cooperation to track vessels and financial flows.
