Environment Moalboal’s millions-strong sardine schools sustain many kinds of animals, like tuna, dolphins and even seabirds. To avoid predators, the tiny fish form complex, flowing shapes. the world’s oceans in vast schools. In Africa, individual sardine schools are seven kilometers long and nearly two kilometers wide! Forming the building blocks of the marine food chain, they gorge on wafting clouds of zooplankton and are in turn eaten by larger marine predators like mackerel, tuna and sharks. Six major sardine species are commercially-harvested in the Philippines – and except for fish geeks, they all look alike (silver fish with beady eyes). Though small in size, their economic contribution is anything but tiny. In 2015, the country netted 344,730,201 kilograms of sardines, amounting to PHP7.43 billion – proving that the industry is one of the country’s major economic drivers. Thousands of Filipinos are employed as fishers, traders or factory workers in the canning, fish drying and bottling sectors, Zamboanga alone employing over 30,000 people. Though the production trend for sardines seems to be increasing since the year 2000, some local stocks are showing signs of overfishing – like smaller sizes for mature fish and dwindling catch rates for commercial ring-netters. Despite the sheer size of sardine shoals, they aren’t limitless. CONSERVING PHILIPPINE SARDINES Armed with massive nets and tracking gear, commercial fishing vessels with can make short work of sardine schools – even those as large as the ones in Moalboal. Without proper management, they may someday be overfished to the point of extinction. Impossible? The story of the Passenger Pigeon – once among Earth’s most common birds – is ominous. A single, billions-strong flock flying above Southern Ontario in 1866 was 1.5 kilometers wide and 500 S ardines: small, cheap, faceless fish packed in cans. Just how important are they? Oceana’s Gregg Yan dives to see them in a whole new light. Swoosh! Swoosh! Swishing and swarming around us is an endless wave of sardines, moving as one to avoid circling predators like tuna and mackerel. I’m with underwater photographer Danny Ocampo and we’re diving in Moalboal, known for its ‘sardine run’ – where millions of sardines aggregate just meters from shore. Beneath us, hungry mackerel swoop down like dive-bombers. In an instant, dozens of hapless sardines are gone. The rest swoosh on and the bubbling free-for-all continues, floating silver scales all that’s remaining of the departed. UNCANNED When I ask people about sardines, they’re usually equated with 555, Ligo, or for the more nostalgic ones, Rose Bowl (some also equated them with the MRT or LRT). But what do sardines actually look like? Surprisingly, most people don’t know, for when they peel open sardine cans, they get faceless fish swimming in sauce, heads and tails already chopped off. Sardines are bullet-shaped fish which cruise 60 Gregg Yan is the Director for Communications of Oceana Philippines and a student of nature.
