The Science

The Science

Over 40 species of symbiotic parasites live on the gills and within the guts of yellowtail. [2]

Taxonomic description

  • Has a blue body, yellow tail, and silver sides with a bronzy stripe along the lateral line. [2]
  • Grows to 2.5 m in length and weighs up to 36.3 kg, with the largest weighing in at 41.3 kg (91.1 lbs). [2]


  • Found along the eastern Pacific from southern Washington to Mazatlán, Mexico (for California Yellowtail). [1]

Life history

  • Has an average lifespan of 5-6 years with a max of 12 years. [2]
  • Females can spawn at 2-3 years old and release up to 150 eggs during spawning, but about 100 eggs are fertilized at a time. Yellowtail eggs are externally fertilized, with the females releasing eggs into the water column, and the males spraying sperm over the eggs. [2]
  • Spawning occurs during the summer, from June to October. [10] Younger females spawn once during the spawning season, while older ones can spawn multiple times. [2]


  • Lives near rocky reefs, kelp beds, and offshore islands. [2]
  • The eggs and larvae are eaten by mollusks, echinoderms, crabs, and fish. [2]
  • Common predators of adults are great white sharks, California sea lions, and humans; the fish’s blue and silvery color is an adaptation to help camouflage from predators. [2]
  • Preys on round herring, sardines, squids, anchovies, and California flying fish. [2]

The Fishery

The Fishery

No California Yellowtail can be taken commercially if it is less than 28 inches (71 cm) long. [9]

Seasonal availability

  • Fishing is open year-round, but between May and August limits to pounds of yellowtail per boat apply. [4]

Regulatory and managing authority

  • As established by the Marine Life Management Act, the California Fish and Game Commission regulates the fishery, and the California Department of Fish and Wildlife manages this fishery. [12]
  • As yellowtail is caught as bycatch by fisheries targeting other species, this species is not included in any specific fishery management plan, but still falls under the jurisdiction of NOAA fisheries under the Marine Mammal Protection Act and CDFW and CFGC as per the Marine Life Management Act. [6,12]

Gear type

  • Sometimes caught as incidental catch in the drift gillnet fishery, and is also targeted with hook and line. If targeting yellowtail with drift gillnets, the mesh size must be ≥3.5 inches. [6]

Status of the fishery

  • Is a largely sought after sportfish, but no decline in population sizes has been detected. [7]
  • Commercial catch declined when purse seining (1973), and later, gillnets (1994) were banned in California waters (CDFG 2001). [1]
  • There is currently no stock assessment or fishery management plan in place for California yellowtail. [1]
  • Currently no conservation acts apply. [1]

Potential ecosystem impacts

  • Yellowtail is a secondary and tertiary consumer in its ecosystems, so its presence helps create the population structure for its prey. Removal of yellowtail may impact populations of its prey and predators. [2]

The Seafood

The Seafood

Known as Hamachi in sushi, this fish has a buttery texture due to its naturally high oil content. [3]

Yellowtail nutrition facts

Edible portions

  • The meat (muscle), head and roe are edible, remaining parts may be used in broth or soups. [3]

Description of meat

  • Light red to pink in color, and buttery due to its high oil content. [3]

Culinary uses

  • Yellowtail is commonly used raw in sushi as sashimi or smoked. [3]
  • It is sold fresh and frozen, and whole, in fillets or steaks. [3]
  • Recommended cooking styles include broil, grill, and saute.

Nutritional information 

  • 66% of the calories are from protein, while the rest 34% are from fat. [10]

Toxicity report

  • Yellowtail have high levels of histidine, which is converted to histamine by bacteria when the fish spoils and can cause histamine toxicity. To avoid this, make sure to refrigerate the fish properly and do not eat if spoiled. [5]

Seasonal availability

  • It is available year round. [1]
