In recent decades, thousands of marine reserves have been established to protect our oceans. Yet, widespread poaching currently makes the vast majority of these reserves ineffective.<\/p>\n

Ensuring the protection of our oceans means we must stem the tide of poaching. However, doing so requires understanding how much poaching is going on and the reasons why people do it. This information is particularly difficult to get because poaching is illegal, clandestine, and often socially unacceptable, so people don\u2019t like to talk about it.<\/p>\n

My colleagues and I studied poaching by recreational fishers in the Great Barrier Reef Marine Park<\/a> (GBRMP) using rigorous social survey techniques designed to study illegal behavior (such as poaching) and ground-truthing measurements (i.e. counting lost and discarded fishing gears). In the March 2017 issue of Frontiers of Ecology and the Environment<\/em>, we reported that between 3 and 18 percent of recreational fishers admitted to poaching in the last year, which is higher than previously assumed. We also identified concentrations of poaching activities at certain times (holidays) and places (poaching hotspots) previously thought to be among the best protected in the GBRMP.<\/p>\n

Fishers gave two main reasons for poaching: their belief that there would be higher catches in reserves and that the probability of detection was low. This suggests that extolling certain ecological benefits of reserves in places where enforcement is limited could actually encourage poaching. We suggest that increasing the perceived risk of detection (i.e. naming and shaming offenders, or publicizing new detection technologies such as drones or night vision) may help to stem the rising tide of poaching on the Great Barrier Reef.<\/p>\n
