Pacific Bonito

Species: Sarda chiliensis (Cuvier, 1832); from the Greek word sarda  (an ancient name for a European species of bonito) and chiliensis (in reference to Chile, South America, where the species was first recognized).

Alternate Names: Most commonly called bonehead but also given the names bone, boner, bonefish, flasher, magneto and bongo. In the past often called “poor mans tuna,” striped tuna, little tuna and, derisively, Laguna tuna. One of my favorites names—from the PFIC Message Board—Mr. Bojangles. Called bonito del Pacífico oriental in Mexico.

Identification: Tuna-shaped, elongated and pointed at both ends; a series of 6 to 8 finlets that follow the second dorsal fin and anal fin. Coloring dark blue above with greenish reflections and a metallic luster shading into silver below; several dark oblique lines on the back.

Size: To 40 inches although most caught from piers are less than 24 inches. For years the California record fish was listed as a fish that was caught in Malibu Cove in 1978 with a weight of 22 lb 3 oz. Today the record is listed as a 21 lb 5 oz. fish taken at the 181 Spot in 2003. I’m not sure why the new, lighter fish is the record (and I haven’t been able to find out).

Range: There are two subspecies. One, the northern population, Sarda chiliensis lineolata, is found from Southern Baja California and Gulf of California to Copper River in Alaska. The southern population, Sarda chiliensis chiliensis, is found in the subtropical eastern Pacific, Peru to Chile, and off Japan. As a general rule they’re only found north of Point Conception during El Niño, warm-water conditions (and I witnessed several large bonito, all over ten pounds, being caught off of Elk in Mendocino County during the El Niño year of 1983).

Habitat: Pelagic, although enters bays, especially those with warm water outlets.

Piers: Common at most southland piers during and after warm-water years, both those in bays and those at oceanfront spots. Best bets: Ocean Beach Pier, Oceanside Pier, San Clemente Pier, Balboa Pier, Newport Pier, Cabrillo Mole (Avalon)—#1, Redondo Beach Pier, and the Hermosa Beach Pier. Stearns Wharf (Santa Barbara) and Goleta Pier can be decent, especially in the fall.

Shoreline: Sometimes taken by shore anglers fishing from jettys in southern California, especially the jetty at Redondo Beach.

Boats: One of the favored boat species although the numbers can show a drastic change year-to-year depending upon water temperature.  

Bait and Tackle: Bonito primarily feed on fish and squid and are taken on a variety of baits and lures. The best bait is live anchovies or small sardines fished on a sliding leader or with a cast-a-bubble. The best lure is a bonito feather affixed to either a cast-a-bubble, a wooden float, a Styrofoam float, or a golf ball—the bubble/float/golf ball causes commotion on the surface which attracts the bonito and keeps the lure near the top.

Food Value:  Bonito are considered fairly good quality but require cleaning soon after capture. If bled quickly, or even better if filleted and then put on ice, the flesh can be quite tasty. However, if allowed to warm up in a gunnysack on the nice hot surface of a pier the flesh can be almost inedible (which is true with many fish). Some parts of the flesh are dark colored—bloody and strong flavored. Remove those parts of the flesh unless you desire them for smoking. Given the high oil content of the flesh, the best cooking methods are broiling or bar-b-cuing the meat; the worst are methods like deep-frying that would add more oil. In addition, smoked bonito and pickled bonito are also very good.

When I was young, and lived in San Diego, I would often go out on the half-day boats to catch some bonito. Most of the bonito (in the gunnysacks) would wind up as fertilizer for my mom’s roses. However, a couple of the cooks on the boats would cook up some of the fresh-caught fish. A favorite method was to cut thin slices of meat from the head of the bonito (up behind the eyes) and then lightly cook the slices on a grill using just a little butter. Flavored with soy sauce, it was delicious. Today, given that we’ve all become gourmands, we would probably serve the thin slices raw as sashimi and include a little dipping sauce, i.e., wasabi paste and soy sauce draped over a daikon radish. One recommended dipping sauce even includes fish flakes from bonito, it’s a sauce made from shōyu (a type of soy sauce), mirin (a sweet cooking wine) and the bonito flakes.

Comments: Many people feel that bonito are among the strongest fighting fish, pound for pound, in the sea. For many years the place to go for bonito was the Redondo Sportfishing Pier in Redondo Harbor. This was especially true during the colder-weather winter months. That narrative was altered when the nearby power plant changed ownership and changed procedures. Instead of always being on, and sending a steady stream of hot water into the harbor (where it emerged at the famous “bubble hole”), it became a sporadic occurrence. Visitors never knew when the hot water, or the bonito, would be showing up.  Locals learned to check out the tall towers to see if they were emitting smoke. If they were, the hot water would be bubbling up in the harbor and bonito probably would be present. Today the pier is closed but hopefully will be rebuilt. Many also hope the warm water will return to the harbor.

Bonito or bonita? The correct spelling is bonito but a surprisingly high number of people over the years, including journalists and writers who should know better, have used bonita as the moniker for these fish. One day on the Pier Fishing in California message board someone said his daughter had been called a bonito and she got upset until someone told her that the name meant pretty in Spanish. People then chimed in that she should have been called a bonita since that was the feminine name and bonito was the masculine name. As for the fish, given the strong, powerful fight they typically put up, I think I will stick with bonito as the name.
