Marine fishing in the Philippines - Marine fishing in the Philippines is more than an industry; it is a way of life. With 7,100 islands, the Philippines has the world's longest discontinuous coastline. Over a million Filipinos are engaged in marine fishing. Of these, an estimated 800,000 are small-scale fishermen using tradition, low-cost techniques, notably net fishing from small boats and the fish corral. The fish corral is a stationary pen that traps fish in coastal fishing grounds. Traditionally, these techniques have provided small-scale fishermen and their families with a means of subsistence. In the past two decades, however, their way of life has been threatened by the rapid commercialization of Philippine waters.
