Illegal, unreported and unregulated (IUU) fishing may occur on the high seas or within a national jurisdiction. Several factors were identified as contributing to the occurrence of IUU fishing activities, among which is poor governance marked by limited and overlapping enforcement by related authorities. With very limited regional enforcement bodies and the absence of a regional multilateral agreement, IUU fishing is difficult to overcome. It means that issues relating to overfishing and other fishing conflicts like foreign vessels intrusions and use of illegal fishing methods will continue to be a problem. This paper identifies the Malaysia's legal framework governing IUU fishing, as well as relevant international and regional laws and policies. The paper also discusses the devastating effects of IUU fishing to the global fish stocks and national economy. Although the existing framework is considered comprehensive, it recommends further stringent and fair law enforcement to combat IUU fishing in Malaysia's waters.

Since fishing is a primary source of income to the coastal communities, conservation of marine natural resources is crucial to safeguard its sustainable supply. Therefore, intensive measures should be taken by all the stakeholders - from the authorities to the local fishermen. The precious coral reefs should be protected as important breeding habitat of various commercially valued species of marine resources and. Thus, in carrying out the political process of designating marine protected areas (MPAs) as marine parks, the local communities must also be engaged by the government due to their proximity to and dependency on the environment as direct resources users. Co-management or collaborative management by engaging the local communities, or community-based management, is the concept that could be able to remedy ineffective MPAs management in Peninsular Malaysia. Co-management or collaborative management approach between the authorities and the communities must be strategised by factoring in their local knowledge of living within and off the marine environment and resources. This study utilises content analysis method on the primary data, namely the national policies, federal acts, and state enactments. While the secondary data in form of official reports, scholarly articles and others deemed relevant are used to supplement and support the findings. This paper dwells on the possibility of shifting the process of MPAs designation from political process to co-management in Peninsular Malaysia, in order to achieve both environmental stability and the livelihood sustainability of the local communities.
