Challenges and Conservation

Migratory fish face a host of challenges that jeopardize their populations. These challenges include habitat degradation, pollution, climate change, and overfishing. The construction of dams and barriers can also impede their migration routes. To address these issues, various conservation efforts are being undertaken.

Restoration of Critical Habitats: Protecting and restoring the vital habitats that migratory fish depend on is crucial. Efforts are being made to remove obsolete dams and enhance fish passage systems to enable them to complete their journeys.

Sustainable Fisheries Management: Implementing sustainable fishing practices is essential for preserving migratory fish species. Regulations and quotas are being put in place to prevent overfishing and protect these species from depletion.

Climate Change Mitigation: As climate change affects water temperatures and currents, it poses a significant threat to migratory fish. Addressing climate change through reducing greenhouse gas emissions is a key component of their conservation.
