Bonito Fish

The Bonito fish is a medium-sized, predatory fish. Bonito fish have stripes on their backs and a silver underside. Four different species of Bonito Fish can be found across the globe.

These fish are popular with both commercial and sport fishermen. They are also used as bait to catch larger fish.

Types and Scientific Name

Four main species of Bonito Fish are most commonly recognized. They are the Atlantic Bonito, the Pacific Bonito, the Indo-Pacific Bonito, and the Australian Bonito. The scientific names for these species are Sarda sarda, Sarda chiliensis, Sarda orientalis, and Sarda australis, respectively. The term Sarda refers to the genus that Bonita Fish belongs to. The second word in the scientific name for each species refers to the area where the Bonito Fish can be found.

• Atlantic Bonito (Sarda sarda): Just like the other subspecies of the Bonito, the name tells you where they can be found. These can be found in the shallow waters of the Atlantic Ocean, as well as in the Mediterranean Sea and even the Black Sea. Their populations play a large role in commercial fishing.
• Pacific Bonito (Sarda lineolata): While there was some debate about these being a subspecies of Sarda chiliensis, they are considered game fish because they put up a good fight and can be found in schools ranging from as far north as the Alaskan coast and as far south as Baja California.
• Eastern Pacific Bonito (Sarda chiliensis): These can be found on the western coast of South America from Chile to Ecuador.
• Indo-Pacific Bonito (Sarda orientalis): Also known as mackerel bonito and striped bonito, these Bonitos are found swimming in the East Pacific and Indo-Pacific waters. It is not uncommon to find them swimming with schools of tuna. Their backs have narrow stripes, which helps give them one of their nicknames.
• Australian Bonito (Sarda australis): Found in the waters around Australia and New Zealand, this type of Bonito is also referred to as horse mackerel or even “little bonito. They typically do not reach more than 40 inches or 22 pounds.

These fish belong to the Scombridae family. There are 51 species in this family. Some of the other fish in this family include tuna, mackerel, and butterfly kingfish. Bonito Fish is part of the Actinopterygii class.

Appearance

These fish can grow to be up to 30 inches long. They have a more streamlined body that is similar to that of a tuna. Their backs are blue with longitudinal stripes, and their undersides are silver. A Bonito Fish’s tail is forked with a narrow base.

Distribution, Population, and Habitat

The four different species are spread out in different areas of the globe. Pacific Bonitos can be found between Chile and the Gulf of Alaska, though most are located in warmer areas near southern California and Mexico.

Atlantic Bonito Fish are found between Norway and South Africa. They can also be found in the Black Sea, the Mediterranean Sea, and the northern Gulf of Mexico. Australian Bonitos are found in temperate areas near New Zealand and Australia. The Indo-Pacific Bonito’s range extends from the Gulf of California to Peru. They can also be found near the Oceanic Islands, with the exception of Clipperton.

These fish choose different areas for their habitats. Some can be found in more open water areas, whereas others frequent kelp forests that are closer to the shoreline. In general, younger fish are more commonly found closer to the shore. They may also swim into bays or harbors. Larger adult Bonitos may swim up to 300 feet below the surface.

There is not a lot of information about the total population of these fish or each individual species, but the fish is not considered to be threatened. They have a conservation status of least concern according to the International Union for Conservation of Nature.

Predators and Prey

What Eats Them?

Bonito Fish face a lot of natural predators. Striped marlin, swordfish, bluefin tuna, pelagic sharks, thresher sharks, shortfin mako sharks, and other large fish like to eat bonitos. Additionally, marine mammals like dolphins and sea lions also prey on them.

Humans also hunt bonito Fish. They are hunted both for sport as well as commercially.

What Do They Eat?

Bonitos are predatory fish that eat other smaller fish and sea creatures. Some of their favorite foods include anchovies, squid, sardines, herring, mackerel, and shrimp. The diet of a bonito will vary among species based on the sea life present in their habitat. However, all bonito fish are predatory, carnivorous hunters.

Reproduction and Lifespan

These fish reach sexual maturity around the age of two. The time of the year when spawning occurs varies by species. For example, Atlantic Bonitos typically spawn during the summer, while Pacific Bonitos spawn between the end of January and May.

Bonitos are broadcast spawners. This means that they release the sperm and eggs (also known as gametes) into the water, where they will be fertilized. After the eggs are released, neither the male nor the female does anything to watch over the eggs or care for the young. Approximately three days after being released, the eggs will hatch.

Fishing and Cooking

These fish are fished both recreationally and commercially. Some people catch smaller bonitos to use as bait for larger fish, such as mackerel. Additionally, people often share that catching a bonito is good practice for tackle fishing. While these fish are caught all year long, more are caught during the spring or summer.

These fish are sometimes used in cooking, but many people find their flavor too strong and their texture unpleasantly oily. The meat of a bonito is dark red.
