SERDANG: Ninety per cent of the country’s waters is now free from intrusion by foreign fishing boats since an operation code-named ‘Op Naga’ was launched last April, said Agriculture and Agro-Based Industry Minister Datuk Seri Salahuddin Ayub.

He said during the period, 160 foreign fishing boats were detained in the South China Sea and the Straits of Melaka, resulting in a significant increase in the catches of local fishermen on the East Coast and the West Coast.
