Introduction: The Rhythms of Data in the Blue Realm

In the grand narrative of the Revised Taiwan Provincial Chronicles, the ocean is not just a geographic boundary but the lifeblood of Taiwanese civilization. Through the archival lens of the Economy Chronicles: Fishery Affairs, we see not cold statistics, but an epic of migration, survival, and technological leaps. From the Ming and Qing fishermen fleeing taxes to the modern leap of 910,000 tons, these figures reveal how Taiwan transformed from a traditional fishery dependent on nature into a vital hub of the global maritime economy.

Geographic Connectivity: Historical Grounds and Modern Hubs

According to the Fishery and Jurisdiction Chronicles, key coordinates of maritime governance and reclamation include:

  • Penghu Islands: A “paradise” for early Quanzhou and Zhangzhou fishermen fleeing taxes; a Patrol Inspection Division was established here in the Yuan Dynasty.
  • Wang-gang (Wengang): The starting point for fishing boats reaching Taiwan in Ming records, located near modern-day Budai and Beigang.
  • Lower Tamsui (Donggang): The central harvesting zone for mullet during the peak season in the Dutch and Qing periods.
  • Keelung, Suao, and Hualien: Deep-sea fishery bases on the east coast where the Kuroshio Current flows.
  • Chihkan (Tayouan): The center for fishery trade and tax management during the Dutch period.

1. Data Origins: Why the Sea Was the First Map for Ancestors

Archives reveal that the rise of Taiwan’s fishery was closely linked to tax pressures on the mainland.

  • Tax-Driven Migration: During the Ming Dynasty, fishermen along the Fujian coast suffered from heavy levies and intrusive inspections. They fled to Penghu and Taiwan to make a living in remote, resource-rich waters.
  • Natural Fishery Advantages: Taiwan’s west coast sits on a shallow continental shelf (less than 100m deep), while the east coast faces the Kuroshio Current, a vital route for migratory species like tuna and billfish.
  • Early Trade Data: Records show that during the Dutch period, about 100 junk boats came to Tayouan annually for fishing and trading venison. A single shark was taxed one stuiver, earning the East India Company 10,000 guilders per year.

This sea-ward expansion, driven by survival, laid the earliest settlement foundations for Han people in Taiwan—fishery was a precursor to land-based agriculture.

2. Taxation and Power: From Tax Farming to Fiscal Relief

Local records document the historical extraction and management of marine resources.

  • Tax Farming in Dutch and Ming-Zheng Eras: The “Jian-gang” (taxed ports) system involved merchants bidding for the right to collect taxes, often leading to severe exploitation of fishermen.
  • The Mullet Flag System: During the Qing Dynasty, a “Mullet Flag” system was implemented for the highly seasonal mullet catch. Each flag cost 1.2 taels of silver, with Fengshan (modern Kaohsiung/Pingtung) yielding the highest revenue due to its location.
  • Shen Baozhen’s Fiscal Turning Point: In 1874, Commissioner Shen Baozhen realized that tax collectors and local gentry were monopolizing profits. He petitioned to abolish various maritime taxes to relieve the burden on the poor.

The data reveals a shift in governance logic: from pure resource extraction to providing safety and tax equity for maritime operations.

3. A Century of Output Fluctuation: 1940-1981

The Fishery Affairs chronicle provides a set of startling comparative figures, outlining the destruction and reconstruction caused by war and technology:

  • Pre-War Peak (1940): Fishery output reached 119,521 tons, a record high during the Japanese period.
  • Post-War Collapse (1945): Due to WWII, output plummeted to 16,862 tons, less than one-seventh of its peak.
  • Recovery and Take-off (1952-1981):
    • 1952: Recovered to pre-war levels (110,000 tons).
    • 1960s: Surpassed 600,000 tons.
    • 1981: Reached 910,000 tons, with tuna exports becoming a primary pillar.

The secret to this 50-fold growth was the transition from “coastal bamboo rafts” to “deep-sea power.” Archives record the introduction of large-scale purse seine technology in 1967, expanding operations to the Atlantic and Indian Oceans.

4. Ecological Codes: Kuroshio and Resource Fluctuations

Biological observations in the chronicles reflect ancestral wisdom regarding marine ecology.

  • The Power of the Kuroshio: Records show the east coast’s Kuroshio Current can exceed 28°C in summer, providing an ideal path for migratory fish.
  • Resource Instability: Archives mention that while whaling existed in eastern Taiwan, it was eventually abolished by the government due to “unstable whale resources” and international conservation trends—an early sign of ecological adaptation.
  • Mullet Migration Data: Mullet migrate south to spawn every year around the winter solstice. The precision of these ancient “biological clocks” guided fishing activities for centuries.

Modern Revelations: Governance Logic Across Generations

From the fishery data in the Revised Taiwan Provincial Chronicles, three lessons for modern marine governance emerge:

  1. Geographic Advantage is the Canvas of the Blue Economy: Taiwan’s position at the crossroads of the Kuroshio and the continental shelf makes deep-sea fishing an inevitable strategic choice.
  2. Technological Iteration is the Only Way to Break Through: Without the revolution from bamboo rafts to 1,000-ton deep-sea vessels, Taiwan could not have achieved a 50-fold increase in output amidst resource depletion.
  3. Governance Efficiency Dictates Industrial Survival: From ancient “Tax Farming” to Shen Baozhen’s fiscal relief and modern acceleration programs, government policy remains the conductor of industrial prosperity.

Conclusion

The Fishery Affairs section of the local chronicles is a dataset written in sweat and salt spray. From ancient taxes on “Mullet Flags” to modern satellite-tracked deep-sea fleets, every advance Taiwan made on the ocean proves the resilience of civilization at the edge of nature. To respect marine data is to respect the deepest survival wisdom of this land.
