As one of the most popular fish in the world, narrow-striped Spanish mackerel (Scomberomorus commerson) has attracted great attention from fishermen and food lovers, especially in Southeast Asia. This mackerel is not only famous for its delicious meat, but also an important economic source for the local fishery. From the coast of Australia to the coast of Southeast Asia, the wide distribution of narrow-striped Spanish mackerel and its place in local culture make us wonder: why is this fish so highly regarded in the market?
The narrow-banded Spanish mackerel's body is a vivid blue to dark grey hue, fading to a silvery blue-grey underside, which adds to their appeal.
The narrow-striped Spanish mackerel is easily recognisable by its size, reaching up to 200cm in length and weighing up to 70kg, making it the largest of all Australian mackerel. Adult narrow-banded Spanish mackerel have distinct vertical stripes down their sides, features that enhance their presence as they move through the water.
This fish is mainly distributed in Southeast Asia, covering from the east coast of Africa to the northern coast of the Indian Ocean, and Fitz in the South Pacific. This widespread distribution makes it an important component of the region’s fisheries, and its influence in the local economy and culture cannot be underestimated.
Narrowstriped Spanish mackerel's breeding behavior usually occurs on the edge of coral reefs in marine environments, and the eggs have large oil droplets to enhance buoyancy, making the breeding season each year a peak catch for fishermen.
Narrowstriped Spanish mackerel have a relatively short lifespan, usually reaching maturity at two years of age or 80 cm. Their breeding season is usually associated with higher water temperatures, which is essential for the rapid growth of the young fish. Before the breeding season, they form aggregations, which makes fishing more focused and effective.
As a voracious carnivorous fish, the narrow-striped Spanish mackerel's diet mainly consists of small fish, shrimp and squid. When hunting, they display strong hunting instincts, further demonstrating the ecological adaptability of this fish.
Narrow Spanish mackerel is widely fished in Southeast Asia and has become an integral part of local culinary culture. Whether grilled, cooked in soup, or eaten raw, they will delight your taste buds.
In Southeast Asia, narrow Spanish mackerel is primarily fished using the reel method and a variety of tackle. Taiwan’s fishing methods are particularly particular, and many chefs use live bait or artificial bait to ensure the freshness and deliciousness of the catch. In addition, with the implementation of conservation policies, for example, the Queensland government in Australia has significantly reduced commercial fishing quotas, reflecting the emphasis on sustainable fisheries.
In Taiwan, narrow-striped Spanish mackerel is known as "white gold" and is sold at extremely high prices in the market. In 2022, even a 34-kilogram extra-large fish was sold for more than US$3,000. The high price not only reflects its nutritional value and deliciousness, but also that it is one of the important sources of livelihood for local fishermen.
As human demands on marine resources increase, aquaculture becomes a viable option. In 2023, the Taiwan Fisheries Research Institute successfully carried out artificial breeding of narrow-striped Spanish mackerel, which is expected to not only reduce the pressure on wild fish catch, but also achieve the goal of sustainable development in long-term fisheries management.
Although the farming technology of narrow-striped Spanish mackerel has gradually matured, we still need to pay attention to avoid introducing diseases such as parasites to ensure food safety and ecological balance.
As demand for narrow-striped Spanish mackerel continues to grow and its role in the global market continues to rise, it is worth considering whether this brilliant fish of the ocean is of economic, cultural or ecological importance. What impact will the treasure have on the future of fisheries?
