THE SCIENCE
Bonito populations fluctuate in accordance with the warm/cold water periods associated with the Pacific Decadal Oscillation.
Taxonomic description
- Head ispointed and conical with a large mouth.
- Has a compressed body with slanted dark stripes on their backs and upper sides.
- Lower jaw has 14-25 teeth, and is moderately large.
- Reaches 79-102 cm (31-40 in) in length and can weigh up to 11 kg (24 pounds). [4]
- Characterized by a large spleen and lack of swim bladder.[7]
- Was formerly considered subspecies of Sarda chiliensis.[18]
Distribution
- Ranges from the Pacific Ocean from the coast of Alaska all the way down to the tip of Baja California, Mexico. [9]
Life history
- Reaches sexual maturity at the age of 2 and have a maximum lifespan of 6 years. [2]
- Spawning generally occurs from late January until May.[11]
Habitat
- Bonito is a pelagic fish that lives 80-200 meters (262-328 ft.) deep,migrating farther offshore as it grows older.
- Eats fish (such as sardines and anchovies) as well as squid.[3]
- Predators of bonito are larger fish such as tuna, bonito also prey on each other as well. [1]
THE FISHERY
Fishing for bonito occurs offshore in 300-600 feet of water.
Seasonal availability
- Fishing is allowed year-round, but most catch is landed from June-November.[3]
Regulatory and managing authority
- As established by the Marine Life Management Act, the California Department of Fish and Wildlife (CDFW) collects data on and manages this fishery.[2,15]
Gear type
- Mostly taken by purse seine, but are also caught by gill nets, trawl, and hook and line. [2,8]
Status of the fishery
- Currently, bonito is placed in the category of least concern because the catch per year has decreased significantly since the 1990s due to increased regulationand decreased market demand.
- Catch peaked in 1966 with 4.6 million fish declining with a loss of 659,000 in the 1990s.[3]
- In 2014, 70,982 pounds (32,196 kg.) of Pacific Bonito were caught in California.[6]
Potential ecosystem impacts
- Purse seines arenon-selective, which poses risks to non-target species. [12]
THE SEAFOOD
Bonito is sometimes dried,fermented, and smokedto make bonito flakes, or Katsuobushi, in Japanese cuisin
Edible portions
- Can be eaten whole.[4]
Description of meat
- Meat is deep red to pink, soft with a fishy smell but a bold and flavorful taste. [14]
Culinary uses
- Available whole, as filets, or steaks.
- Should be bled and put on ice immediately after catching, and bloodlines should be removed. [14]
- Generally brined prior to cooking.[5]

- For recipe for grilled bonito, visit Greedy Gourmet. [17]
Nutritional information
- For fresh Bonito, there are 5 calories per 129 serving (100 g) and 28grams of protein. [13]
Toxicity report
- As with other top predators, may contain high mercury levels; follow consumer guidelines especially for pregnant women and children. [10]
