Bonito Fish 101: Catching, Tasting, And Cooking Made Easy

Guide to catch & eat Bonito fish

Bonito fish are cousins of the tuna fish, and they are often referred to as trash fish, because they are most commonly used as bait, despite being a fierce predator in the wild.

They aren’t really that common as food, but some people find them to be absolutely delicious. Bonito fish are completely safe to eat, and as we’ve said, some people find them delicious.

However, these fish have a very strong and harsh flavor, as well as an oily texture, so not everybody finds them appealing, and whether they are nice or not depends completely on every individual’s preference. 

It is very common for people to question, time and time again, whether they are actually safe to eat or not, because of their very unique and “different” flavor. We will reiterate that they are completely safe to eat, and you might really enjoy them! 

What are Bonito Fish?

Bonito fish aren’t exactly popular, or a well-known dish, so you might have never heard of them before. That’s why it makes sense for us to start from the very basics, and explain exactly what Bonito fish are. 

Basically, Bonito fish belong to the Scombridae family, and they are cousins to better-known fish such as mackerel and tuna.

They live in salt water only, and are not very common as food, hence why you’ve probably never heard mention of them at any markets! 

They have a very unique texture and taste, which sets them apart from other fish, and they are usually used as bait for fishing. 

Oh, and fun fact, Bonito means “pretty” in Spanish….but these fish aren’t exactly considered to be appealing. In fact, their nickname is “trash fish”, kinda mean! 

There are a few traits that set the Bonito fish apart from all the rest, and which you can look out for in order to identify them. Here they are: 

  • They are ray-finned. Bonito fish have rays on the tips of their fins, which in the wild serve them to guard themselves and also to be intimidating towards other species. They are, after all, predators! 
  • They have a very aggressive nature and are known as one of the fiercest predators. They are hard to catch, and are known to start fights with other fish! 
  • They are oval in shape, which helps them swim better. 
  • They eat other fish, mainly sardines. 
  • Bonito fish are known for swimming very long distances, so they have a lot of endurance! (This also means that if you get in a tug of war with them, they will be able to keep going for ages!)
  • They usually swim in large schools, as they are very social amongst their own kind. 
  • They are usually found near the shore. 

However, despite Bonito fish having some unique traits and personalities that should easily set them apart, it is actually very easy to accidentally confuse a Bonito fish with a Tuna. Most beginners do! 

Bonito fish are unique in their species, but they are categorized by their age and their region. 

Here are the main different categories, or types, of Bonito fish:

Old Bonito Fish

Old Bonito fish have very dark and firm meat, with moderate fat content. 

Young Bonito Fish

Young Bonito fish are smaller in size, with pink and light meat, and barely any fat content. 

Regional Bonito Fish

Regional Bonito fish are either Atlantic or Australian, and this depends on the region in which they are located. 

How to Catch Bonito Fish

As a general rule, we recommend that you use a line between 4 and 8 pounds, as these will get you the most Bonito fish! 

Fishing Rod

Using a fishing rod is the good old classic fishing method, simple and straightforward. However, it requires technique and a lot of patience.

You will ideally need a rod that is sturdy and strong, as Bonito fish can put up quite the fight! 

Oh, and if you are going to try and catch some Bonito fish, then here are some tips that we have, that might come in super handy:

  • Use frozen bait! Bonito fish love it! 
  • If you are using live bait, we recommend sardines or pilchards, as this is what Bonito fish are most likely to bite. 
  • While you are fishing, combine placing the bait at the bottom of the water with having it floating around, so that you can tempt as many Bonito fish as possible!
