A first global study published in Nature found reef sharks were absent on almost 20% of the 371 coral reefs sampled in 58 nations across the world. The study provides conclusive evidence of a severe decline in reef sharks on a global scale which is directly linked to fishing, but confirms protected areas and fishing gear restrictions are effective in maintaining healthy reef shark populations. The results were based on 15,165 hours of baited remote underwater video (BRUV) footage around the world.
