Lake Baikal’s Arctic Cisco Declines by 28%: What You Need to Know

Arctic Cisco Population on the Decline

According to a recent report by the Federal Agency for Fishery of Russia, the Arctic Cisco population in Lake Baikal has experienced a significant decline of 28% since 2019. This decline has raised concerns among scientists and environmentalists, as the Arctic Cisco plays a vital role in the lake's ecosystem.

Causes of the Decline

The exact causes of the Arctic Cisco decline are still under investigation, but several factors are believed to be contributing to the problem. These include overfishing, pollution, and climate change.

Overfishing

Arctic Cisco is a valuable commercial fish, and overfishing has been a major factor in its decline. In recent years, the number of fishing vessels operating in Lake Baikal has increased significantly, leading to overfishing of the Arctic Cisco population.

Pollution

Lake Baikal is also facing increasing pollution from industrial and agricultural sources. This pollution can harm the Arctic Cisco and its habitat, making it more difficult for the fish to survive and reproduce.

Climate Change

Climate change is also believed to be a contributing factor to the decline of the Arctic Cisco. Rising water temperatures and changes in the lake's ice cover can affect the fish's spawning and feeding habits.

Impact on the Ecosystem

The decline of the Arctic Cisco has a significant impact on the Lake Baikal ecosystem. Arctic Cisco is a major food source for other fish species, such as the Omul, and its decline could lead to a ripple effect throughout the food chain.

Conservation Efforts

Efforts are underway to conserve the Arctic Cisco population in Lake Baikal. The Russian government has implemented fishing quotas to reduce overfishing, and is working to reduce pollution in the lake. Scientists are also studying the effects of climate change on the Arctic Cisco and are developing strategies to mitigate these effects.

Conclusion

The decline of the Arctic Cisco in Lake Baikal is a serious issue that requires attention. Overfishing, pollution, and climate change are all contributing factors to the problem, and conservation efforts are needed to protect the remaining Arctic Cisco population. By taking action now, we can help to ensure the future of this iconic fish and the Lake Baikal ecosystem.
