Sturgeon Poaching in the Caspian Sea: A Hidden Battle

In the waters off Dagestan, a silent crisis is unfolding. Local fishermen have turned to sneaky tactics to catch sturgeons, a species already pushed toward the brink. Researchers set out to uncover why these illegal hunts keep growing even as government rules tighten. They spoke with 53 fishers from 24 small groups between 2020 and 2021. The questions were simple: how many trips do they make? How much fish do they bring home? The answers were checked against written logs to keep the data reliable. Because fish populations change with seasons, the team built a yearly model that smooths out those ups and downs. They also used statistical tools to break down the patterns of catching fish, seeing how long each group stays on the water and how many boats are active. The results were startling. From 2018 to 2021, the groups caught about 82, 000 kilograms of sturgeon in just over three hundred trips.While the number of active groups fell from 21 to 17, each remaining group worked far harder. The months they spent fishing rose by almost half, and the total catch per group jumped 49 percent. Yet when looking at how much they caught each month, the efficiency dropped. This shows that stricter laws haven’t stopped poaching; instead, they pushed fishers to squeeze more out of fewer boats. One possible reason is a state hatchery program that, while meant to boost sturgeon numbers, may also provide extra fish for illegal buyers. The program unintentionally fuels a vicious cycle: more sturgeons mean more fishers, which leads to more illegal fishing and even more harm to nearby seals. The root of the problem lies in how isolated communities feel left out. When people have few legal job options, they rely on fishing for survival. Trying to protect the sturgeon without addressing these social gaps only locks everyone into a loop of overfishing.
