An Underestimated Marine Treasure and Its High-Value Development Potential
Round scad (also known as jack mackerel, or Decapterus spp.) is a globally important, highly migratory pelagic fish species widely distributed across tropical and subtropical waters. Characterized by its laterally compressed, spindle-shaped body and fast-swimming, schooling behavior, round scad supports large commercial catches worldwide.
In recent years, this modest-looking small fish has undergone a significant industry revaluation. From 2024 to 2026, global research teams have conducted multi-dimensional, high-value studies on round scad, positioning it as a new favorite in marine food technology and the broader health industry.
Since 2024, a series of studies have focused on the deep processing of round scad. For instance, research in 2024 successfully produced round scad protein hydrolysate powder using bromelain and alkaline protease, opening up applications in high-end nutritional supplements. Another comparative study the same year investigated the neuroprotective effects of round scad‑derived peptides, revealing significant potential against neuroinflammation and providing a scientific basis for functional foods.
Sustainable utilization of round scad relies on sound management. A 2025 study revealed the reproductive biology of round scad in the Sunda Strait, identifying peak spawning periods in May and July, with female sexual maturity at 187 mm body length - key biological references for fisheries management.
Beyond being processed into fishmeal or frozen products, round scad is now achieving higher market value. The latest research (May 2026) demonstrates that surimi gel strength derived from round scad is significantly enhanced. The resulting high‑toughness surimi performs excellently in the development of premium traditional foods such as "Yanpi" (meat‑wrapped paper), substantially broadening the market channels for round scad.
Thanks to its massive biomass, high nutritional value, and continuously discovered bioactive compounds, round scad is transforming from a low‑cost feed ingredient into a rising star in human nutrition, medical foods, and biomedical raw materials. As marine protein resources become increasingly precious, high‑value development of round scad represents a win‑win strategy - delivering economic benefits while ensuring sustainable use of ocean resources.
