overfishing
- Illegal, Unreported, and Unregulated (IUU) Fishing
Extent of IUU Fishing: It is estimated that IUU fishing accounts for 10-31% of the global fish catch, valued at up to $36.4 billion annually. This illegal activity undermines sustainable fishing practices and threatens fish populations.

-
- Inadequate Fisheries Management
Regulatory Challenges: Many fisheries lack effective management and oversight, particularly in international waters. This leads to overexploitation of fish stocks as there are few regulations to control fishing practices.
-
Subsidies: Government subsidies can encourage overfishing by making it economically viable for fishing operations to continue even when they are not sustainable. This results in an overcapacity of fishing vessels.

-
Market Pressure: The global demand for fish continues to rise, leading to increased fishing efforts. This demand often drives fishermen to catch fish at unsustainable rates, further depleting stocks.

- Bycatch and Environmental Impact
Bycatch Issues: The practice of bycatch, where non-target species are caught unintentionally, contributes to the decline of various marine populations. This not only affects the targeted fish species but also disrupts the entire marine ecosystem.

-
Fishing Effort: The intensity of fishing activities, including the technology and methods used, significantly impacts fish populations. Overfishing occurs when the fishing effort exceeds the reproductive capacity of fish stocks.

The combination of these factors creates a complex challenge for marine ecosystems and fish populations worldwide. Addressing overfishing requires coordinated efforts in regulation, sustainable practices, and consumer awareness to ensure the long-term health of our oceans.
