The humble beginnings of being called “Tuna Capital” (1940s – 1960s)

In Sarangani Bay resides indigenous B’laan groups who mastered fishing. Using bamboo traps and handlines, they were able to catch on-shore tuna. Their fishing techniques let them celebrate how much they saw. But as time went into the late 1940s, migrant fishers from Visayas and Luzon started arriving.

They brought advanced fishing techniques like beach seines, drift gillnets, and ring nets. Back then, tuna was a delicacy often dried or salted. That was until they discovered the power of refrigeration and canneries.

Venturing out to the deep (1960s – 1970s)

By the 1960s, an empty feeling started to plague Sarangani Bay. But that didn’t stop the anglers who set their sights on Moro Gulf waters and the Celebes Sea.

This era introduced large motorized boats that were lovingly called “unay.” It also had refrigeration. This alone changed the game.

The 1970s invited international buyers from all over. One of them was Japan and America, which marked the beginning of the export industry for tuna.

Canneries take center stage in General Santos City (1980s – 1990s)

When the 1980s hit, tuna in General Santos reached its golden era. Giant players like RFM, Purefoods, and General Tuna came in to establish canneries for themselves.

And it didn’t stop there! By the time the next decade rolled around, six canneries were built. That’s when they officially earned their title as canned tuna capital. They also experienced a boom in infrastructure, with buildings like the General Santos Fish Port Complex and cold storage facilities ensuring only fresh catches every time.

Dominating the Mighty Oceans (1990s to the Present)

The insatiable global desire for tuna kept growing. To satisfy this never-ending demand, General Santos took its fishing endeavors to even greater depths, venturing far offshore. Equipped with state-of-the-art tools such as payers, helicopters, and sonar, the city became an unstoppable force.

Today, General Santos proudly boasts of contributing 40% to the Philippines’ tuna production, exporting only the finest sashimi-grade tuna. Far from being just a delectable seafood source, the tuna industry now provides livelihoods for over 100,000 workers, making it the lifeblood of the city’s economy.

What are the types of Tuna caught in General Santos City

General Santos City is home to a multitude of tuna species, each playing a significant role in both the local economy and culinary landscape.

Yellowfin Tuna (Thunnus albacares) – This abundant and economically vital species reigns supreme in GenSan, accounting for over 50% of the catch. Its sought-after status is attributed to its excellence in sashimi and canned tuna offerings.

Skipjack Tuna (Katsuwonus pelamis) – As the second most prevalent tuna variety in these waters, skipjack makes up approximately 25-30% of the catch. It finds purpose in canning and local consumption.

Bigeye Tuna (Thunnus obesus) – Renowned for its high value and export potential as sashimi-grade fare, bigeye tuna possesses a high-fat content that makes it ideal for grilling purposes.

Frigate Tuna (Auxis thazard) – Constituting around 8% of the catch, frigate tuna is a smaller species utilized by local canneries and markets.

Eastern Little Tuna (Euthynnus affinis) – The diminutive eastern little tuna accounts for less than 1% of the overall catch.

Other tuna species, including albacore and bluefin, are present but in lesser quantities.

It is found across tropical and temperate waters worldwide. Typically reaching lengths of up to 1 meter and weighing up to 40 lbs. When cooked, its dark red meat exhibits a low-fat content and soft and flaky texture.

It is known for its robust “fishier” flavor profile compared to yellowfin.

Growing well beyond 2 meters in length with potential weights reaching an impressive 400 lbs.
